Creating a solid from 3D Faces

Recommended Posts

Hello,

 

I tried to create a solid using 3dpoly but for some reason I am not able to transform this closed 3dpolylines into surfaces.

Then I just created 3dfaces.

How do I generate a solid using all of this 3dfaces?

 

Thank you

What exactly are you trying to create that first tried using a 3Dpolyline then switched to a 3DFace?

 

While I am waiting on a reply, and without the benefit of knowing/seeing what you are attempting to create, I will suggest one possible solution. Convert the 3Dfaces to surfaces using CONVTOSURFACE then use the SURFSCULPT command to generate the required solid. Caveat: the surfaces better be watertight otherwise SURFSCULPT will fail.

 

Still no reply?

 

OK. Here is a second possible solution that I thought of. Find and use the F2S lisp routine created by Bill Gillis. It is described thusly...

 

F2S.lsp creates a single ACIS solid from selected 3dfaces, touching or not

 

If neither one works then you did something wrong and I have no other solutions to offer other than to recreate the object from scratch using a different method.

It seems I did everything you mention in your post. Convtosurface didn't work with 3dpoly (or randomly worked), also using surfsculpt doesn't work with the surfaces created from 3dfaces.

I tried F2S and the solid created is not even close to how the solid should look like.

I thought that Convtosurface will turn all the closed 3dpolylines into surfaces, but as I said It is not consistent (only surfaces parallel with X plane were created). Any idea why this is happening?

You want me to diagnose the problem without the benefit of seeing a drawing? No can do. Attach a copy of the drawing to your next post. If the file size is too large then upload it to a file sharing website like DropBox then post a link to it here.

What did you do after the Loft?

How did you create the top and btm surfaces? with Surfpatch?

For solid did you use Surfsculpt?

Thanks

After the loft I created the top and bottom surfaces using lines and the EDGESURF command. Then it was a matter of just using SURFSCULPT to create the solid.

If SURFSCULPT doesn't work with separated surfaces, try before the command UNION in order to obtain a single unified surface.

But the end result has to be a "watertight" surface otherwise SURFSCULPT will not work.

Yes, right. Also self intersections have to be avoided.
