When I export, I'm either getting the error message "No mesh objects selected!"or I get a file that I can't import into Simplify 3D--it's either empty or unreadable. I think I've tried everything to fix this and can't get it to work. I'm running the latest version of ViaCad (V9, Build 1109) on a Mac using OS 10.7.5. If there's someone from Punch who can look at the file, I'd be glad to send it. Any help would be appreciated!

Punch/Encore does not monitor the forum. If you need immediate support, please contact Encore tech support. If you want development or users to take a look, post your file with steps to repeat. Tim

The problem occurs using export and selecting STL file format. I'd appreciate any advice you could give me on this.

I had selected/grouped the original polygons used to make the shapes and tried to export them in the .STL. Hiding all of the polygons and ungrouping/selecting all solids, then exporting to the .STL with the "selected items" box checked solved the problem. Thanks, Eric

STL export wants mesh, surfaces or solids. Your part has the solids inside a group. If you can ungroup your solids, you should be able to export as STL. I am updating the code so that it also takes groups. We should not need to ungroup to export STL. This correction with be in the 1147 codestream. Tim
