I created a model in Alibre Design, which includes a number of threaded holes. In Alibre's documentation it says that while you don't see the threading on the render, it's included in the design data.

I exported from Alibre to an .stl file and uploaded to shapeways. The shapeways preview likewise shows smooth holes, not threaded holes. If I order a piece, will my holes be threaded or not?

Thanks
Tom

Open your stl in this. WYSIWYG from Shapeways, you can zoom right in.
You can check, repair, measure and scale your file.]]> JACANT 2012-09-30T21:36:02-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=55780&th=11017#msg_55780
Alibre keeps track of that information for the sake of design drawings and bills-of-materials, but it's not capable of generating actual screw threads; any holes will be simple smooth-sided bores. If you want threads you'll either have to cut them into the finished part or create the contours yourself via the Helical Cut tool.]]> VeryWetPaint 2012-10-22T21:52:58-00:00
