From 3D to 2D

[saitoib]

Hi all.

I want to create a 2D projection from a 3D object.
I have done a lot of research and the only way to do this in AutoCAD is to use the Flatshut command?

It seems that when I create a 3-sided view with Flatshut, I have to create each projection one at a time.
Is there a lisp or something that will automatically create a 3-dimensional view?

Thank you.

Instead of destroying the 3D object try command _VIEWBASE (and commands based on that) >>>details<<<.

Are you confusing FLATSHOT with FLATTEN?  FLATSHOT doesn't destroy the 3D object.

Hi,

oh yes, you are correct, my fault, sorry!

It sounds like you don't "want to create a 2D projection," but rather multiple projections.  It's not clear to me what you mean by the "a 3-sided view" vs. "a 3-dimensional view," or whether those are the same.  Can you post an image or drawing showing the kind of result you're looking for?  If by "side" you mean orthogonal-direction projections such as in typical technical drawings, should it be from 4 sides, and maybe from 6 directions, rather than 3?  If by "3-dimensional" you mean something like an isometric view, from which point(s) of view?

FLATSHOT doesn't have a command-line version, so I expect it will be necessary to finish it out with the dialog box for each view, but at least the changing of view directions, and the starting up of FLATSHOT for each projection, can probably be automated.

I'm sorry I can't explain it better.
I want to create the plan view in image B from the 3D object in image A.

That is opposite from what the title said.

You wanted a bunch of 2d views to 3d.

Thank you for your guidance.
I have not used any 3D functions in AutoCAD before, so I had no idea about this kind of process.
I will study it.

Thank you very much.

Hi,

well, command _VIEWBASE and it's functions were already pointed out in the first reply in this thread (yesterday) 😉

I'm sorry, my English is very difficult, so I missed it.
