Rather than slamming 3d printing, how about an assist in
designing/processing the parts for printing?

Most of the posters have a knowledge of cad, and can create
a 3d wire form of an object. and have access to a cad
program.

What hints would you care to give to the group for creating
3d surfaces from a wire frame model, particularly compound
curved surfaces and inside corner radii, so these are
"manifold" and can be processed through a "slicer" program
to generate the FFF g-code file for 3d printing?

Do you know of any [free] VBA or AutoLISP macros or add-ons
to "skin" a DXF/IGES wire frame?

I'm going to continue to tell it like it is about 3D printing and CADCAM. So will others that are members of CADCAM Technology Leaders group on LinkedIn.

No CADCAM company or 3D printing expert that I know of wants anything to do with Usenet. I completely understand why.

I haven't used AutoCAD in a over a decade. No machining job shop I know of uses AutoCAD any longer. AutoCAD is the past. I'm done with it. The only place I ever see AutoCAD is woodworking shops.

When I want to skin a wirefame I use Delcam PowerShape. Delcam employees are very active on CADCAM Technology Leaders.

If you or others choose to ignore what's clearly a very strong and successful group to get answers that's your choice. There is a ton of info on CADCAM Technology Leaders that you can't find anywhere else.

Times have changed and many machinists/CADCAM programers think Pay 4 Play rags like slow eddy works for can't be trusted.
