The rule of thumb is that for smoothest curves, you need to have faces that are 1/2 the size of the minimum resolution of the printer.
For WSF, the Min Detail is 0.2mm, so WSF curves need to have segments less than 0.1mm
For FUD, they'd need to be 0.05mm or smaller.

If your model is in inches, then your faces are 3.5mm wide around the circle. There are just 3 faces across the corner I've hilighted above. You'll need 24 or more faces across that corner for smoothest ouptut from the printer.]]> stonysmith 2013-02-20T16:12:54-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=62474&th=12953#msg_62474
I get what you are saying. Is there some way I can increase the number of polygons in the stl file after it is drawn? I am using Catia and am unsure how to create a smoother Radius in the part designer to create a smooth surface when it is saved to stl.... I have uploaded another file and with much worse looking radii and as you can imagine I would not want this in a print. ]]> Longhornss 2013-02-20T16:47:16-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=62476&th=12953#msg_62476 as described here on objet.com]]> mkroeker 2013-02-20T17:04:32-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=62487&th=12953#msg_62487
Is there anyway I can verify the models before I send them for printing? ]]> Longhornss 2013-02-20T19:50:34-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=62489&th=12953#msg_62489 ]]> mkroeker 2013-02-20T20:15:58-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=62492&th=12953#msg_62492 Longhornss 2013-02-20T20:50:59-00:00
