Dear Aysu,

Welcome to Wolfram Community, we are glad to have you!

Please do not post several question on the same discussion.

If you have a new question, then make a new post.

The 2nd question you asked on this discussion thread was posted separately here:

Is it possible to write the code and manipulate it in grasshopper?

Please keep you comments here in accordance with original subject and use other posts for other subjects.

Sincerely,

Moderation Team

P.S. We recommend reading this post for the beginners: How to post and use Wolfram Community

Glad to help. If you turn that surface into something architecturally interesting, I'd love to see it.

Use Paste Snapshot from the pop-up menu at the upper right.

Edit the resulting expression, changing DynamicModule to Module, and assign to "graphics":

graphics = Module[...

Export the graphics:

Export["Structure.3ds", graphics]

Chris

This makes a simple parametric surface:

surface = 
 ParametricPlot3D[{Cos[u], Sin[u], v}, {u, 0, 2 \[Pi]}, {v, 0, 1}]

This exports it in Maya format:

Export["cylinder", surface, "Maya"]

And this exports it in 3DS format:

Export["cylinder.3ds", surface, "3DS"]

I can't say why the example you gave didn't export. If you post the expression that created the surface, I can take a look.
