View Full Version : I need a solid from existing surfaces. HELP!
2007-10-24, 06:10 PM
Okay, I am at my wit's end trying to figure this out. How would I use a cylindrically enclosed set of surfaces to create a 3D Solid? I didn't originally design this, otherwise I would have started as a solid. Looking at the JPG, the left is the surface parts, the right is my revolved outer cylindar. I can't figure out where to go from here. Is there a way to just basically, fill in the hollow surface model, so that I can have a 3D Solid? If not, how would I make this into a 3D solid? Am I making this more difficult that it needs to be? Thanks for any help you can give.

Programs like Mechanical Desktop and Inventor will stitch surfaces into solids. Can you zip and post the file?

Here's the drawing. If you can do anything with it, let me know how to do it. :) Thanks.

There is no command in AutoCAD 2007 that can convert your complex surface to a solid. I would do the job in Autodesk Inventor.

Fair enough. I have a student version of Inventor R 11. What would I do to make these surfaces workable? When I import it into Inventor, all the pieces are automatically made into one part. I can select and highlight each individual surface, but I can't figure out how to manipulate any of them. I can't even delete any of them. Any advice?
BTW: Maybe the next version of AutoCAD should have a way to do this. :)

Your surfaces do not form a "watertight envelope" therefore you cannot stitch to a solid. Parts of the surface model are missing.

Well, this is only part of the whole bottle. I don't want to have to go through permissions to post a proprietary drawing on here, so I just sent the neck of the bottle. If were to make the enclosing top and bottom, would it then be able to be made into a solid and then sent to AutoCAD?

Try internet for m2s.lsp.
