Hey Steve,

It's been awhile since I used Bridgeworks, but I remember that we usually did not check supports. With lightyear we used to check every part also. We now have enough experience to know which part supports need to be edited.

If you are going to the 3D Systems North American Stereolithography Users' Conference you can discuss this issue face to face with 3D Systems. Also, send an e-mail to Patti Brown ( and discribe your problem so that we can discuss this at the 3D wishlist panel! If you e-mail them now they will have the information for you at the conference.

In response to Brad, we set the MSA at 30. On some parts we go as high as 46.
