Hi
I have created in AutoCAD a solid model of one of the bones in a wrist by extruding and then offsetting a stack of 69 polylines representing the outlines of the bones. This gave me 69 thin slabs of solid which I then unioned together to make a solid model. Since the model was created from 69 discrete slabs, it has an artificial looking "stepped" surface shape.
In an attempt to smooth the surface of the object, I exported the model as a 3D studio model. By setting the weld vertex threshold distance to be just greater than the slab height, the stepped effect was eliminated, leaving me with a nice smooth surface.
Now I've got a model that is beautiful to look at, but which I can't actually use...
I now need to perform Boolean intersection and union operations on the smoothed bone within a geometric modelling program that only accepts ACIS solids. So I imported the 3DS model back into AutoCAD and saved it as an ACIS. However this failed with the message: "No solids or regions selected"
My question is:
Is there a way of converting a "watertight" surface model into a solid that can be imported into AutoCAD. The acid test is whether or not AutoCAD can successfully export the converted object to an "ACIS" SAT file.
Any help greatly appreciated.
