Design Review 2011 Autodesk

How many times did you sent a drawing to your client for Revision... And the only thing that you received as a feedback was a completely different without meaning drawing?
It would be better if you just give them a copy of your work and the permission only to comment anything they want on it without destroying your drawings changing your Dims & by accident deleting some lines.
With Design Review you'll have the ability now to Publish your Models with their necessary Manufacture Drawings in a .dwf or .dwfx format and send your work to your client without worries...

The following video comes from Youtube as it is and the only purpose is to give a better explanation of Design Review tool by Autodesk and How is this work.

AutoCAD Useful Commands

Tracking Point ---> "tk"
It helps you to locate a desirable Point in space. Starting from an End Point
without any sketch lines you can dynamic insert any value you want as you pull over your cursor in any direction you desire.

Properties Palettes ---> "Ctrl+1"
It's display the properties changes of a selected geometry and it lets you to modify your Layer, Points, Dimension, Scale, etc.

Enter Snap
Specify snap spacing or [On/Off/Aspect/Rotate/Style/Type] <5>: s (Style)
Enter snap grid style [Standard/Isometric] <S>: i (Isometric)
There are appears now three isometric angles that you can draw.
Set them through the F5 or "Ctrl+E".

_ellipse (Iso Circle )
Specify axis endpoint of ellipse or [Arc/Center/Isocircle]: enter i (Isocircle) right-click
Specify center of isocircle: pick or enter coordinates
Specify radius of isocircle or [Diameter]: enter a number

Recall
This command gives you the ability (when select an object) to call the same command that have been used for the selected object.

Wolfram Demonstrations Project

An alternative view in science

Conceived by Mathematica creator and scientist Stephen Wolfram as a way to bring computational exploration to the widest possible audience, the Wolfram Demonstrations Project is an open-code resource that uses dynamic computation to illuminate concepts in science, technology, mathematics, art, finance, and a remarkable range of other fields.

Annoying Acronyms

noreply@blogger.com (Ioannis Skarlatakis) — Wed, 01 Dec 2010 11:05:00 +0000

There are many times when you start to read an article or a brochure or even an advertisement and you meet some of : D F T , P I D or you could misunderstood F E A with F M E A. I know that every professional should be familiar with the acronyms of his/her sector. However there will always be an annoying acronym that has been escaped from your mind collection or probably you don't remember it the right time.
For reasons like these which mentioned before I made a small collection of seldom acronyms or maybe not that common that could help some of us who want a further explanation
I will try from time to time or under your suggestions to grow up this collection in the section of Mechanical Design and relatives sections in engineering.

Newton Law's

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

II. The relationship between an object's mass m, its acceleration a, and the applied force F is

F = ma.

Acceleration and force are vectors in this law the direction of the force vector is the same as the direction of the acceleration vector.

III. For every action there is an equal and opposite reaction.

"Based on the second law we consider that 1 N(Newton) is the net force that's requared for an object of 1 kg mass to travel with acceleration of 1 m/s²."

1N ≡ 1kg m/s²

1N ≈ 0.22481 lb_F

1pdl ≡ 1 lb·ft/s²

1 pdl = 0.138254954376 N
