Re: AutoCad STL Files

Let me share with you a couple of hints. I have been using STL files
from Autocad solid models for running parts on an FDM 1650 and I've
rarely had a problem. First of all I always use solid models rather than
surface models for STL generation because a solid is 'watertight'. I can
always be sure this way. You can play with the facet resolution of solid
with an Autocad command called 'facetres'. The default is .5, but if you
raise it, you you will get a much finer detail model and smoother
surfaces (but with a cost of more processing time). Also, always make
sure that the solid model is in the positive x,y,z octant. Hope this
