<<< "In CV when we hand our programmers our geometry to cut (NC program)
they receive it as a solid since that's how we build it. We generally
'piece-meal' the programmers information as we complete it or as they need
it (airfoil blocks here, shrouds there, etc.). In order for the
programmers to be able to utilize the information, they must break it
apart, so to speak. I don't believe CV will cut solid geometry so the
programmers must turn the solids into surfaces. They do so by 'extracting'
the faces or surfaces from the solid. These generally are untrimmed
surfaces which the programmer must then retrim to one another to create a
useful surface model with which to cut. CV will allow extraction of faces,
surfaces and even edges." >>>
If I'm following, you can export discrete surface, quilts, curves (?), etc.
from Pro/E. Quilts can be selected from within the export dialog. Curves
probably require a little layer manipulation (I've never done it, but
believe it should be possible).
<<< "Generally when we receive models in engineering from the customers,
they are already surface models, not solids so we don't usually have any
problems. We've tried to call this .igs file up into CV, but it has bombed
out on us or is missing a lot surfaces or other information. Since we are
learning Pro/E I wanted to take this opportunity to try it there. The
quilt list IS in the Layer Tree as mentioned. They all have the same name
and highlight the entire model when selected.
The subject in question is a rework tool. Therefore I only need a small
portion of the original model which has a LOT of information in it. We
thought by 'extracting' only the geometry that we need, any subsequent .igs
conversion would have a greater chance of compatibility and completeness
since the translator is dealing with a considerably smaller file. The tool
we generally use in UG to 'extract' the surfaces does not work with this
One way: Set the selection filter to "Geometry". Highlight and select a
surface. Menu: Edit / Copy, then Edit / Paste (or ctrl+C and ctrl+V). The
Copy dashboard will open and you can (I think) select additional chained
surfaces. (There are intricacies with the "selection" process that I don't
want to get into; I don't understand them well enough to explain, but they
can be figured out and there is a tutorial on PTC's site.) Once you have
copied all the required surfaces, export and specify the quilts to be
exported (look for the Quilt button in dialog).
Another, maybe easier way: Put the reference file in an assembly and start
a new part file (in the assy). Go thru the copy routine and just export
the part file (don't have to worry about filtering the exported entities).
<<< "When I build a solid in Pro/E I am able to highlight any surface or
feature individually, but not w/this .igs translation. If I were able to
'extract' the surface, radius or other information in a more precise
manner, it would be helpful." >>>
You should be able to, I think. When you have trouble selecting something
that you think you should be able to ditch the Smart selection filter and
set it to the type entity you are after.
You can also determine whether import feature surfaces are treated as
surfaces or quilts. Select the Import Feature, Edit Definition. Menu:
Edit / Feature Properties, clear the Join Surfs box. (It's actually a
little more complicated sometimes; you may have to go thru an Edit Boundary
to get the surface out of a quilt, but let's save that for another time if
it's really necessary <g>.)
<<< "I apologize if this isn't very clear as I'm still trying to grasp how
Pro/E works and I know less about UG which makes for a frustrating time in
trying to explain all of this and then ask for the help I need when, in
fact, I don't know exactly where I need the help.
If exporting from UG using different modifiers is the key, then we're
willing to try that. If the key is getting a better model from the
customer then we'll start there, but I doubt we'll get very far. By better
model I mean that a UG-native model SHOULD be able to extract it's own
geometry, but this model will not allow it." >>>
Shouldn't be any major problems getting what you want, or shouldn't think
so. Holler back if you can't get it figured out. What version Pro/E are
you using (I've missed it if you've said)?
<<< "Btw, anyone on here have experience using Pro/e in the specific
discipline of jet-engine airfoils and airfoil tooling?" >>>
Turbine components or airframe? Can't claim to "know" anything about
airfoils, but do occasionally deal with them in the course of doing
airframe structural repairs. I also do some occasional tooling for static
test fixtures, though the only airfoil related one I've done was a winglet
fixture. Whatcha wanna know?
