Tutorial for Surface Modeling

[Anonymous]

Does 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 started writing one but the example I had wasn't
the best in the world so I but it on the back burner.  If you could post an
example of your part maybe I could use it as an example.  Of course that
doesn't help you right now.

I've had surfaces created right in Inventor that wouldn't thicken for no
reason I could discern. The surfacing toolbox in R6 is perhaps half full,
and still has some quirks, and the developers know that. It was a good
start, but they couldn't get it all in in one release. But Inventor is not
really being touted as a full-fledged surfacing tool....yet. When I saw the
design philosophy behind what they'd done, I was very pleased. I like the
way Inventor jumps between surface and solid seamlessly. It's truely a
hybred system, and when it's fully developed, it's going to be awesome.

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.

I have several tutorials on surface modelling in my Inventor Intermediate R6 text which is available from SDC (www.sdcacad.com).

The intermediate text should be available to ship the end of February.
