To change the appearance of the schedule you must change the appearance of the block.

Changing Colors

The colors of the entities are set in the block. To change the color, you must open the block and change the color there. Changing the color of the layers in the regular customization commands will not change the color of the schedule.

Changing Text Styles

The text location, style, and justification is also set in the block. Labels are inserted as regular text. Values that are updated are inserted as attributes. To change any of these settings, the values must be changed in the block. When the schedule is updated, the attribute value will be updated, but all the other settings will left alone.

Opening and Redefining the Right Blocks

The schedule consists of a header block, a different block for each phase (A, B, and C), a footer block, and a wrap block. Each block must be modified individually.

To modify a block, insert the schedule that you want to modify. Use the DM Electrical->Customization->Open Block from Drawing command and select part of the schedule. The block definition will be opened for you.

Make the necessary changes in the block and save it.

Then use the DM Electrical->Customization->Redefine Block in this Drawing command and select the same part of the schedule to update the block definition. Then, erase the schedule and reinsert it. It is necessary to erase and reinsert the schedule in order for some attributes value to be properly updated.

Be careful when opening and redefining the phase blocks. A common error is to modify the block associated with one phase and to then redefine a block associated with a different phase. It will appear that nothing has changed, when really the wrong block was selected.

Schedule Block Attributes

The default schedules do not include all the possible values that can be included in the schedule. To insert more information, use the DM Electrical->Customization->Block Creation->Insert One Line Device Schedule Attribute command.

Once an attribute is inserted, modify the settings to make it look right for the schedule.

The personal protection equipment (PPE) required for the person working on the equipment is based upon the incident energy at the working distance from the equipment. The arc-flash-protection boundary is the distance unprotected works must keep between themselves and the equipment.

In both cases, the calculated energy values will limit the burns on the works to second-degree.

There are three commands you will use when performing arc-flash calculations.

The DM Electrical->One-Line Devices->Set Arc-Flash Values command is used to specify the additional information about panels required to perform arc-flash calculations. Most of the work related to arc-flash is done using this command.

The DM Electrical->One-Line Schedules->Insert Arc-Flash Schedule command will print a schedule on the drawing documenting the arc-flash calculations.

The DM Electrical->One-Line Schedules->Create Arc-Flash Stickers command will create stickers for each of your panels and display them in your web browser. You can then print them using a color printer and sticker paper and attach them to your panels in the field.

Set Arc-Flash Values

When you run the DM Electrical->One-Line Devices->Set Arc-Flash Values command, the following dialog box is opened. It’s big! Click on the image to see a full-size version, or run the command in Design Master Electrical.

Each one-line device is listed as a row in the grid. The bold columns are calculated for you by the software. You are responsible for filling in the other values.

While you are using the dialog box, you can hover your mouse over a column title to see a tooltip that describes the information that goes in the column.

Each of the columns in the grid are described below.

Device: The one-line device. Devices are listed in a tree based upon which devices are fed from other devices.

Calculate Arc-Flash: Whether or not arc-flash is calculated for the device. Devices that are not calculated will not be displayed in the arc-flash schedule on the drawing and will not have stickers created.

Because it is difficult to sustain an arc-flash below 208V, devices with voltages less than 208V do not need arc-flash calculations performed. You have to manually uncheck this box for devices below 208V.

Voltage: The voltage of the device. The voltage determines the arc-flash calculation method that is used. The voltage is set when you create the one-line device.

Equipment Type: The equipment type from IEEE Std 1584-2002 Table 4. The type of equipment selected sets a distance ‘x’ factor. The ‘x’ factor is used as an exponent in the calculation. Higher ‘x’ values result in higher incident energy values.

The following list displays the ‘x’ factor for each type of equipment for voltages between 208V and 1,000V.

• Switchgear: 1.473
• MCC : 1.641
• Panels: 1.641
• Open air: 2.0
• Cable: 2.0

For voltages below 208V and above 1000V, consult IEEE Std 1584-2002. The ‘x’ values are slightly different, but the relative orderings are the same (switchgear is the lowest, open air and cable are the highest).

Configuration Type: Whether the device is enclosed or not. Enclosed devices reflect the arc-flash toward the worker, resulting in larger incident energy values. Most panels and other devices inside buildings should be set to Box.

• Open: no enclosure, lower incident energy
• Box: enclosed equipment, higher incident energy

Grounding: The type of grounding on the device. Grounded devices have lower incident energy values.

• Grounded: lower incident energy
• Ungrounded and high resistance grounded systems: higher incident energy

Gap Between Conductors: The gap between the conductors. The most accurate calculation can be used when the gap between conductors is between 13 mm and 152 mm.  Within that range, the smaller the gap, the larger the incident energy.

If possible, set the gap based the manufacturer’s specifications. Typical gaps between conductors for devices between 208V and 1,000V are listed in IEEE Std 1584-2002 Table 4.

• MCC: 25 mm
• Panels: 25 mm
• Switchgear: 32 mm
• Open air: 10-40 mm
• Cable: 13 mm

For voltages below 208V and above 1000V, consult IEEE Std 1584-2002.

Working Distance: The distance from the possible arc point to the person working on the device. It includes  both the distance from the device to the worker and the distance from the front of the equipment inside to where the arc flash would occur.

The incident energy will be calculated at this distance from the device. The farther away from the device, the lower the incident energy. Any part of the body closer to the device than this distance will be exposed to higher incident energy than is calculated.

If possible, set the working distance based upon the actual dimensions of the equipment. Typical working distances are given in IEEE Std 1584-2002 Table 3.

• Low-voltage switchgear: 610 mm
• Low-voltage MCCs and panelboards: 455 mm
• Cable: 455 mm
• Other: To be determined in field

Bolted Fault Current: The bolted fault current is the fault at the equipment. This value is calculated based upon the other settings in your project. All the arc-flash calculations assume the equipment and the fault are three-phase. For single-phase equipment, the calculations provide conservative results.

Arcing Current, 100% & 85%: The predicted three-phase arcing current used to determine the operating time for the protective devices. For voltages less than 15,000V, the 100% column is calculated based on the values to the left in the grid. The 85% column is based upon the 100% column.

For voltages greater than 15,000V, the arcing current is equal to the fault current.

Arcing Time, 100% and 85%: The duration of the arc-flash has a significant impact on the incident energy. The longer you are exposed to the flash, the more intense the burn.

The arcing time is based upon the time-current curve for the specific breaker you are using. These values are provided by the manufacturer. You typically can find them on their website.

You are responsible for entering two values, one for the arcing time at 100% of the arcing current, and the other for the arcing time at 85% of the current.

The incident energy is a function of the arcing current and the duration. Lower arcing currents that take longer to close the breaker can result in higher incident energy values than high arcing currents. To account for this, incident energy is calculated at 100% of the arcing current value and at 85% of the arcing current value. The greater of the two incident energy values is used to determine the PPE required for the device.

Fuses must be handled differently from breakers. The time-current curves for fuses may include both melting and clearing times. Use the clearing time if it is listed. If only the melting time is listed, for greater than 0.3 seconds add 10%, otherwise add 15% to the time.

If the arcing fault current is above the total clearing time at the bottom of the curve (0.01 seconds), use 0.01 seconds.

Incident Energy, 100% and 85%: The total incident energy is calculated based upon the arcing current, duration, and working distance.

Required PPE: Personal Protection Equipment (PPE) rating required to work on the device. The rating is based upon the larger of the two calculated incident energy values. NFPA 70E 2012 Table 130.7(C)(16) lists the minimum arc rating for clothing in cal/cm². All of the calculations are done in J/cm². Both values are listed below.

• PPE 0: 0-5 J/cm² (0-1.2 cal/cm²)
• PPE 1: 4-16.7 J/cm² (1.2-4 cal/cm²)
• PPE 2: 16.7-33.5 J/cm² (4-8 cal/cm²)
• PPE 3: 33.5-104.6 J/cm² (8-25 cal/cm²)
• PPE 4: 104.6-209.2 J/cm² (25-40 cal/cm²)
• PPE X: > 209.2 J/cm² (> 40 cal/cm²)

Arc-Flash-Protection Boundary Energy: The arc-flash-protection boundary is the approach limit for unprotected workers.

You can specify the energy value. This is the amount of energy that will be delivered at the boundary distance. The default energy value of 5.0 J/cm² will limit burns to an unprotected worker to second degree during an arc-flash incident.

Arc-Flash-Protection Boundary Distance: The boundary distance is calculated based upon the specified Arc-Flash Protection Boundary Energy value.

Insert Arc-Flash Schedule

The DM Electrical->One-Line Schedules->Insert Arc-Flash Schedule command will insert a schedule on the drawing displaying the results of the arc-flash calculation. The schedule can include all of the information in the grid in the Set Arc-Flash Values command. The default schedule displays only a most relevant fields.

The dialog used to insert the schedule works like all the other schedule insertion dialog boxes in Design Master Electrical.

Create Arc-Flash Stickers

The DM Electrical->One-Line Schedules->Create Arc-Flash Stickers command will create a sticker for each one-line device that has Calculate Arc-Flash checked using the Set Arc-Flash Values command.

If the incident energy at the device is less than 40 J / cm2, a warning label will be printed. If the incident energy is greater than 40 J / cm2, a danger label will be printed.

The sticker also will display the shock protection information for the device. Shock protection is a function of the voltage of the device. The values are based upon NFPA 70E-2012, Table 130.4(C)(a).

Examples of the two types of stickers created are shown below.

Creating the pipe sizes, flow categories, and sizing tables can be complicated and will take some time. Once you have configured those to match your companies standards, you will be able to easily size pipes in your projects.

Creating Sizing Tables

There are three customization commands that are used to define the information needed to size pipes.

The DM Plumbing->Customization->Pipe Size command defines the pipe sizes that are available to be used for each pipe type.

The DM Plumbing->Customization->Pipe Flow Categories command defines the types of flow that are available for each pipe type. Flows that have diversity factors can be created using this command.

The DM Plumbing->Customization->Pipe Sizing Tables command defines the tables that are used to size the pipes. The sizing tables set a maximum flow value for each pipe size. Horizontal and vertical pipes can be sized to different values.

Pipe Sizes Dialog Box

Each pipe type is listed in the grid. All of the available pipe sizes are listed below the pipe type. Each pipe type has a separate set of sizes associated with it.

Label: The label that is displayed on the drawing for the pipe size. You can enter any text here that you want. It will be displayed exactly as entered.

Interior Diameter: The interior diameter of the pipe size. This value is not currently used in the software. Future sizing and velocity calculations will use this value.

Exterior Diameter: The exterior diameter of the pipe size, used when drawing the pipe in 3D.

Pipe Flow Categories Dialog Box

Each pipe type is listed in the grid. All of the available pipe flow categories are listed below the pipe type. Each pipe type has a separate set of flow categories associated with it. The order of the pipe flow categories is important.

The first flow category is the one used to size the pipe.  All the other flow categories are converted to the first category before it is sized.

When pipes of different types are connected, the flow is transferred between the different pipe types.  The flow categories are matched up in the order they are listed in this dialog box.

Category Name: The name of the category that is displayed in the pipe query dialog box. This is a display value for the user only. It is not printed on the drawing.

Label Prefix: A prefix that is added to the flow value when it is printed on the drawing.

Label Suffix: A prefix that is added to the flow value when it is printed on the drawing. Make sure to include a space at the beginning of the suffix if you want a space between the value and the label.

Conversion: The type of conversion used to convert the flow category to the first flow category. The first flow category cannot have the conversion set.

Multiplier: The value of the flow category is multiplied by this value to convert it to the first flow category.

Lookup Table: The value of the flow category is converted based upon a lookup table. The Flow Lookup dialog box will be displayed.

The flow is assumed to be a count of the number of fixtures of the type. For example, the displayed lookup table is for water closets with flushometer valves (UPC Table 6-7).

Fixtures: The number of fixtures.

Flow: The corresponding value to use when converting to the first flow category. Enter the total flow value here. In this example, the additional flow for the second fixture is 30 FU, but the total for the first two is 70 FU. The total of 70 FU is entered.

Minimum Pipe Size: The minimum pipe size that is used when the pipe contains the specified number of fixtures. The size can be larger than this if the flow from other fixtures requires it, but it will never be smaller.

Additional Multiplier: The final row is treated differently from the other rows. This is the additional flow that will be added for each additional fixture beyond the last value listed. Here, the flow value is the additional flow, not the total. In this example, each additional fixture adds 10 FU to the total.

Pipe Sizing Tables Dialog Box

The pipe sizing tables convert from the total flow value in a pipe to a pipe size. It is the link between the pipe sizes and the pipe flow categories.

Multiple sizing tables for each pipe type can be created in the grid on the left.

Active: Whether or not the sizing table is displayed when querying a pipe. You will want to define lots of sizing tables in your standards database, however they will not all apply to your current project. Limiting only a few sizing tables to be active will simply your choices when setting the sizing table for a pipe.

Name: The name of the sizing table that is displayed to the user. It is also used as a default for the sizing table schedule printed on the drawing, but can be customized if necessary.

The lookup table that converts a flow value to a pipe size is created in the grid on the right.

Vertical Flow Same as Horizontal Flow: Whether or not vertical pipes are sized the same as horizontal pipes. Check this box to size all pipes the same. Uncheck this box to size vertical pipes differently from horizontal pipes.

Size: Each size defined in the Pipe Sizes dialog box is listed here. These cannot be changed in this dialog box.

Flow, Horizontal: The maximum flow allowed in horizontal pipes of this size.

Flow, Vertical: The maximum flow allowed in vertical pipes of this size. This column will be disabled if the Vertical Flow Same as Horizontal Flow box is checked.

Enable: Whether or not this pipe size is used when sizing pipes automatically. If it is unchecked, this size will not be chosen when sizing pipes, and this size will not be displayed in the pipe sizing table printed on the drawing.

Sizing Pipes

To size the pipes, use the DM Plumbing->Pipes->Pipe Calculations command. Select a pipe in the system you want to size. Each flow category in the pipes will be totaled separately. The flow categories will all be converted to the first flow category. Then the pipe size is chosen based upon this total flow value using the pipe sizing table.

There are two fields in pipes related to sizing pipes. You can modify these values when inserting or modifying a pipe.

Size: Size is pulldown menu of pipe sizes defined in the Pipe Size command. The default value is Sized Automatically. When this is selected, the pipe size will be chosen based upon the flow values and sizing table.

A specific pipe size can be set by selecting a pipe size from the pulldown. The pipe size will not be changed during the calculations.

Custom pipe sizes cannot be entered. You must choose a size from the pipe size list. If you need a different size, add it to the pipe size list, then select it.

Sizing Table: The table used to size the pipe is selected here. All of the active sizing tables will be listed.

You can also choose Same as Previous. If this is selected, the pipe will be sized based upon the previous pipe.

Set the sizing table for the first pipe in the system, then set the rest to Same as Previous.

If the sizing table changes at any point in the system, for example a high pressure and low pressure part of the system, change the Sizing Table setting in the pipe where the change happens. All the pipes before the changed pipe will be sized based upon the Sizing Table setting in the first pipe, and all the pipes after the changed pipe will be based upon the Sizing Table setting in the changed pipe.

Inserting Sizing Tables on the Drawing

The DM Plumbing->Pipes->Insert Pipe Sizing Table command can be used to insert sizing tables on the drawing to document how the pipes are sized.

This procedure is most often used when you purchase a new computer and install Design Master on it. The new computer will have the default customization installed on it. These steps will transfer your existing customization, saving your custom layers, options, and blocks.

1. Find your customization path by running the DM->Help->Installation Settings command.
2. Press the Open button to automatically browse to the folder in Windows Explorer.
   
3. By default the customization folders are called Electrical Customization, HVAC Customization, and Plumbing Customization.
   
4. Select the folders you wish to transfer and copy them to the medium of your choosing (thumb drive, cd, shared folder, etc) using any of the Windows copy commands.
5. On the new computer, close any projects you have open and repeat steps 1 and 2 to find your customization path.
6. Overwrite the folders with the ones you copied previously.  Press Yes to All to overwrite the folder.
   

“base.dcl”
Can’t find file.

Error loading dialog control file.

Semantic error(s) in DCL file.
See file acad.dcl for details.

Cause: One of the standard AutoCAD support file search paths has been removed.

Solution: Manually restore the missing support file search path. The location of the support path depends upon the version of AutoCAD you are running.

All of the support paths are located in your AppData folder. The location of this folder depends upon the operating system you are running.

One simple way to find it is to open Windows Explorer. Press ALT+D to put your cursor in the address bar. Type %APPDATA% and press ENTER. Include the percent signs when you type it in. The current folder will be changed to the AppData folder.

You can also locate it manually.

• Windows XP: C:\Documents and Settings\<User Name>\Application Data
• Windows Vista, Windows 7: C:\Users\<User Name>\AppData\Roaming

Then, the AutoCAD support folder will be located in that folder.

• AutoCAD 2004: <AppData>\Autodesk\AutoCAD 2004\R16.0\enu\support
• AutoCAD 2005: <AppData>\Autodesk\AutoCAD 2005\R16.1\enu\support

When installing an update, it is necessary to update all three programs at the same time. You do not want to update one program and not the others.

It is necessary to have AutoCAD closed on the computer you run the installer on.

None of your existing customization will be overwritten during the update process.

Update Installs for Multiple Users

Install the update to the same location as where you originally installed Design Master.

You do not need to close AutoCAD on the other computers with our software installed.

The next time a user opens a drawing in AutoCAD, Design Master will be updated automatically. They will be prompted to restart AutoCAD if necessary.

This high ventilation requirement is caused by one of the rooms in the zone requiring 100% outside air. The room typically has a small load in it that does not require very much air to condition. The supply air required for the space is lower than the ventilation air required, resulting in 100% outside air. If any space in a zone requires 100% outside air, the whole zone will require 100% outside air when using these calculation methods.

The solution is to increase the supply air required for the critical space. The percentage of outside air required in the space will go down, resulting in the percentage of outside air in the zone going down as well.

Here are the specific steps in Design Master HVAC to take to diagnose and solve this problem:

1. Run the DM HVAC->Building Definition->Project Information command.
2. Confirm that the Ventilation Calculation Method is not set to Minimum. If it is set to Minimum, then something else is causing the problem.
3. Run the DM HVAC->Load Calculations->Print Preview command.
4. Confirm that the Print Ventilation Schedule toggle is checked. Confirm the zone in question is selected to be printed.
5. Press the Calculate and Print Loads button.
6. Locate the Ventilation Schedule section of the print out. The critical room will be highlighted. This room is the one you will need to modify. The Discharge Outdoor Air Fraction should be 1 for this room. Check for other rooms that are set to 1. If there are any, they will need to be modified also.
7. Run the DM HVAC->Building Definition->Rooms->Edit Rooms command.
8. Use the Find button to select the room from step 6 that needs to be modified.
9. Select the toggle next to Minimum Supply Air. Specify a value that is greater than the outside air required for the room. The outside air value can be found in the Zone Outdoor Airflow column of the print out from step 6.
10. Run the DM HVAC->Load Calculations->Print Preview command again and confirm that the Outdoor Air Discharge Air Fraction for the critical zone is less than 1.

The room load is the load that is seen inside the room. This load needs to be accounted for by the air being supplied to the room.

The system load is the load that is seen at the air handler. This is the total load that the air handled needs to account for.

The system load includes the ventilation load and the plenum load. The room load does not include these two values.

Wrap Block

When the circuit description wraps, an additional block is inserted in the schedule to extend the space available for the circuit.

To set the name of this block, go to DM Electrical->Customization->One-Line Diagram Schedule Blocks. Look for the “Circuit Wrap” blocks. The name of the block that will be used is listed there.

To create the block, you will want to start with one of the existing circuit blocks. Insert a panel schedule on the drawing. Use the DM Electrical->Customization->Open Block From Drawing command. Select the panel schedule on the first circuit line. This will open the circuit block for you.

Save the drawing using a new name for the wrap block. Erase all of the text and attributes from the drawing. Change the height of the lines so they are 1 unit tall.

One way to do this is to select all of the lines and use the Properties window in AutoCAD. You can open this by pressing CTRL+1. Set the Starting Y value to 0 and the Ending Y value to -1.

Description Width

The width of the circuit description area is specified in the first circuit block. To modify this width, insert a panel schedule on the drawing. Use the DM Electrical->Customization->Open Block From Drawing command. Select the panel schedule on the first circuit line. This will open the circuit block for you.

The insertion point of the DEND attribute is used as the end of the circuit description area.

If you can find the attribute, move it to the appropriate location.

If it does not exist on the drawing, use the DM Electrical->Customization->Block Creation->Insert One-Line Device Schedule Attribute command to insert it. Insert the Circuit: Description End (DEND) attribute.

After you have modified the location of this attribute in the block, return to your original drawing with the panel schedule on it and use the DM Electrical->Customization->Redefine Block in this Drawing command to select the circuit block. Update the block, then erase the panel schedule and reinsert it.

Design Master Electrical has two types of motor loads: “Single Motor” and “Multiple Motors.” The software uses these load types to determine the largest motor when calculating a feeder size. It always looks at all of the connected motors. For example, when determining the largest motor for a panel, we look at all of the motors connected to the panel, plus all of the motors connected to panels fed from the panel.

The largest “Single Motor” load is used as the largest motor.

If there are multiple “Single Motor” loads, the largest is used as the largest motor.

If there are no “Single Motor” loads, the largest “Multiple Motors” load is used as the largest motor.

For a piece of equipment with a single motor, you want to use the “Single Motor” load type.

If the equipment has multiple motors, you have two choices:

• If there are four or fewer motors, and no other load types, you can specify each motor as a “Single Motor.”
• If there are more than four motors, and you need additional load types, you specify the largest motor as “Single Motor” and the sum of the other motors as “Multiple Motors.” Even if the sum of the other motors is larger than the single largest motor, the largest motor can be determined.

If no motors are designated as a “Single Motor”, the software does not have enough information to figure out what the largest motor load is. It uses the largest “Multiple Motors” load as a conservative choice. The largest motor will be smaller than that, but how much smaller cannot be determined. Sizing that group of multiple motors at 125% might result in a feeder that is too big, but that is better than having it be sized too small.
