IV Surfacing is not industrial strength

Anyone else having good or bad experience with IV surfacing? The first
limitation we encountered was the inability to offset a surface. (Brand SW
had no such problem). The second limitation is that there is no parting
line function. This fundamental and invaluable feature is missing. It's
frustrating to have to go back to MDT for part of the job and then import
into IV to complete the job.

It appears that we will have to wait for another release before IV is ready
to do serious surfacing work. I hope Autodesk is planning to address these
issues.

Russ,

The new Thicken/Offset command works great for me on surfaces : Thicken =
solid output, offset = surface output. Does this not do what you want?

Also, the Split command will do what the part line in MDT does, but only on
solids in Inventor. If you must split a surface a work around might be to
thicken the surface, use the split tool to break the surface and then the
delete face tool to reduce the resultant solid back to multiple surfaces.

Hope this helps.

They are. I remember talking with a developer about the new surfacing
tools. Not everything they wanted made it into R6. They were happy with
what they did have, but knew the toolbox was incomplete. I believe that we
can expect enhancements in R7. I know that world-class surfacing tools are
high on their priority list.

The offset command simply does not work all the time - sometimes it just
can't perform the function.

Regarding the Split command - it works great if you have a part line to
start with. Complex parts require a parting line function in order to
generate a split and there is no tool to do it with.

As a simple example, imagine you are molding a donut. Let the donut start
with its centerline parallel to the z-axis (the hole is facing up). Now tip
the donut about x or y so that its axis is at a 10 deg angle to the z-axis.
Assume your tooling (press) operates in the z direction, so the mold must
completely enclose the part without locking the part in either mold half.
The parting line to do this is two odd-shaped splines around the outer and
inner surfaces of the donut. MDT will do this - IV cannot.

I agree with Russ. I was content (I don't believe I said that) with the
surfacing capability in desktop. Of course I had been using it since it was
called "AutoSurf". The thing about Desktop I didn't like, was the
interaction between surfaces and solids. Neither one knew anything about
the other. I hope the enhancements that Walt is talking about will make IV
more like a Hybrid modeler.
