Possible to convert a Polyface Mesh to a Surface with BricsCAD v19?

cadmonkey

Can I convert a Mesh to Surface in BricsCAD v19? At the moment I need to use a 3rd party program to convert a cloud point survey to a Polyface Mesh (the 3rd party programs only uses Meshes), I then export that Mesh and import in with another 3rd party program to convert the Mesh to a Surface, then I import that Surface into another CAD application to sculpt that Surface to a 3D solid. Was just wondering if I could do everything in BricsCAD instead of using multiple CAD software and 3rd party programs.

V19 has a CONVERTOSOLID.

It will convert watertight Meshes to Solids mostly fine.
Same as by explode : region : stitch
If the Mesh was ok, you will get a nice Solid,
If not, a Surface.

Okay, I have attached a screenshot of the Mesh that I got..It is only a flat Polyface Mesh that I get and the CONVERTOSOLID command does not work. I don't think that Mesh of mine is watertight, I use another CAD software to make is a watertight solid using the "sculpt" command.

I think it would work by
converting all 3D Polygons to Regions
Stitch all Regions.

May give a Solid,
or better looks like a Surface.
Which should work to THICKEN.

I personally would do clean up and all 3D Mesh work in Modo
and finally try to convert that Mesh to Solid in Bricscad.

Can you try to copy your Mesh,
explode (>3D Faces ?),
select 3DS Faces, convert to Region,
select regions and Sitch ?

Should give a Surface,
that you can Thicken (?)

That works for me if I create a Cube Mesh, explode,
delete top 3D Face, make 5 Regions, Stitch.
Gives a Surface to Thicken.

I think Convert to Solid will only work for things that
can finally result in a reasonably Solid with a Volume (?)

Hi Michael, thanks for your help..I will try your above mentioned techniques tonight
