Descriptive Geometry
(OP)
Does the CAD systems do descriptive geometry as we had to do manually years ago?

RE: Descriptive Geometry
By "descriptive geometry" I assume you mean the construction or witness lines used to create alternative views of an object?
If so, then I don't know of any CAD system that does that automatically. Why would they need to? Are you looking for the artistic effect? Any CAD system would be able to easily create the construction lines manually.
RE: Descriptive Geometry
Are you currently using CAD?
Also, you may want to red-flag your other thread. You entered it twice.

On the other hand, if they're stuck doing 2D then maybe it's of use.

RE: Descriptive Geometry
That has happened to me a lot. I wake up and the stupid computer doesn't work!
...then it's back to the drawing board!

RE: Descriptive Geometry
Most CAD systems offer an option to use a grid when sketching in the 3D model and the 2D drawing. The grid lines could effectively be used to do what you are asking.

RE: Descriptive Geometry
You mean you still have a drawing board? Most of us dumped ours. But since I don't yet have the portability of a laptop, I still occasionally use a quad pad, triangles and scale. So the descriptive geometry I learned still gets used.

RE: Descriptive Geometry
Someone that only ever uses 3d CAD and doesn't want to know how or why the program did what it did (I would venture to say that there is not a single designer, engineer, or draftsman worth anything that could say that with a straight face.) doesn't need it. Anyone that wants to understand what they do and not just trust the program to do things right, should know it.
Perhaps not on the drawing board, (although I found that to be invaluable experience as well.) but in AutoCAD at least it should be taught.
Besides if no one learns how to do this stuff, who is going to tell the software programmers what to make the software do?

RE: Descriptive Geometry
No, I don't. Just being sarcastic. I had one up until over 3 years ago, but have not actually used one in about 8 years.

RE: Descriptive Geometry
Most of the problems were architectural and piping with a few planes to figure out.

Everything should be designed as simple as possible, but not simpler.
RE: Descriptive Geometry
I see the same issue all the time.
