anyone have a tutorial for modeling with surfaces? I have never used surfaces
and I really do
not know where to start? My company produces castings of
complex shapes that have no straight
edges on them and are curved, usually
unequally, in all directions. In the past, we have started with
a large
block in part mode and "whittled" it down. Are these types of complex shapes
easier to create
with surfacing?
A tutorial will be helpful.
Thanks,

I know this the Inventor NG but I gotta tell you what I do to deal
with surfaces. I design machines for assembling products which have been
designed in several other cad packages, UG, Catia, SDRC and Pro-e. I get step
and iges translated parts from these cad systems. I then need to "Fix" the
surfaces in order to get them to import as solid models in Inventor. Basically
Inventor needs a closed volume to accept the model as a solid. Check out a
program called Rhino
href="http://www.rhino3d.com/">http://www.rhino3d.com/. It has great
import capabilities and the resulting model if done correctly will import into
inventor as a solid. Some parts are easily converted and others are very
tough. In your case you would be designing in native rhino surfacing, (which
is fairly easy to learn) then you would join your surfaces into a closed
volume and export as a step or acis (Sat) file for import into Inventor. I
heard rumors a while back that autodesk was going to merge rhino surfacing
with Inventor, I don't know if it was true or not but I think it would be a
great combination! I've been an Inventor user since the first release and
to me its the best overall design package for machines, It just needs a
comprehensive surfacing package. By that I mean NOT like the stripped down
surfacing added to Mechanical Desktop.
