To align the workplane with the face of a 3D object

2011-08-22T22:34:00.000-07:00

To align the workplane with the face of a 3D object

The left image shows the user coordinate system not aligned

to the face plate of the 3D object and the right image shows

the user coordinate system aligned to the face plate of the

3D object.

To construct objects on the face of the desk stand in the sample file, align the

XY plane (workplane) of the UCS with the face of the desk stand.

Work with Coordinates in AutoCAD

2011-08-22T22:29:00.000-07:00

Work with Coordinates

The coordinates of the world coordinate system(WCS) define the location of

all objects and the standard views of AutoCAD drawings. However, WCS are

permanent and invisible. It cannot be moved or rotated.

AutoCAD provides a movable coordinate system called the user coordinate

system(UCS). The XY plane of the UCS is called the workplane. In a drawing,

by default WCS and UCS have the same orientation. When you create and

modify objects in a 3D environment, you can move and reorient the UCS in

3D modeling view.

Use the right-hand rule to determine the positive axis direction of the Z axis.

By rotating your hand, see how the X, Y, and Z axes rotate as you change the

UCS.

In this lesson, you will learn how to:

■

Align the workplane with the face of an object

■

Create and modify objects on the workplane of the current UCS

Brick Masonry

2011-07-18T02:11:00.000-07:00

To make a rigid wall of brick, individual bricks are laid together in horizontal layers, or coarses. The bricks are bound together by cementing material or mortar.
The mason spread a layer of mortar with a wide, flat trowel. He then sets the bricks on the mortar pressing them down lightly. If bricks is out of line, he taps gently into place with the handle of his trowel.

How to estimate concrete hollow blocks or CHB

2011-07-14T22:15:00.000-07:00

A wall has a dimension of 35 meters long and and 7 meters high specify the use of 15 cm. concrete hollow blocks. Prepare a comparative bill of materials for CHB.

15 x 20 x 40 cm. CHB wall
find the area of the wall
A= 35 x 7
A= 275 sq. m.

1 sq. m. of a wall consist of 12.5 pcs of CHB

275 x 12.5 = 3,437.5 pcs of CHB
