Igs translation and face/surface extraction |
|
|
Hi group,
We utilize Pro/e (still learning) and CV. We were first told by the Pro/e
outfit that we would be able to call up native UG .prt files in Pro/e. We
have since found that is not true. We only have one seat of UG and there
are no more engineers here that are proficient at it so it has really become
only a way to convert the files for use in Pro/e or CV.
Our problems have been that when the models are brought into Pro/e after
..igs'ing them from UG NX we see the model as only ONE entity, even though
the list of Quilts is long. We cannot seem to find a way to either export
it as surfaces (into Pro/e) or extract the surfaces in Pro/e (which we can
do in UG). When brought up in CV it usually is a surface model, not solid,
but is sometimes missing information. We've tried exporting from UG as an
..igs and as a parasolid, but neither seems more successful in Pro/e.
Anyone know how to extract surfaces (or quilts) in Pro/e?
Thanks,
The Crew

What is "extract"?
If you'll "Edit Definition" the import feature you can manipulate (delete,
repair, etc.) individual surfaces.
If you just want a few surfaces for reference without the overhead of all
the surfaces you can (one of a few ways to go about it, I guess) put your
imported part in an assembly with a "reciever" part and copy individual
surfaces.
I'm curious about the Pro/E / UG interoperability. What are your
experiences? Don't have the UG interface module or it doesn't work for
you? What ver Pro/E? |

STEP works much better for transferring solid model data from UG to Pro/E.
Wildfire can import Parasolid export files from UG.
To get assemblies from UG to show their assembly structure, you must use the
external interface. You can do it from within UG, but you have to elect the
from file option. You can not select the UG data interactively and get the
assembly structure in the IGES file.
If you have solid bodies in UG and are only getting surfaces/quilts in Pro/E
then you need to change the export settings in UG to export the solids. By
default, I think, UG exports surface data in IGES.

I share Jeff's confusion. If I knew what you were trying to do with these
surfaces, I (we) could be more help. There are, in fact, limited ways to work with
imported solids/surfaces. You can use them as they are for 'Merge/cutout'
operations (AutoCAD/UG/Parasolid boolean subtract). Or, you can do Pro/e surface
copy operations; or you can use the imported surfaces for copy geom from other
models ('Insert>Shared data>Copy geometry from other model') which gets you some
independent surfaces to play with. What you need depends on what you are trying to
do with the imported data. Care to share?

Re: Igs translation and face/surface extraction |

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.
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
model.
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.
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.
Btw, anyone on here have experience using Pro/e in the specific discipline
of jet-engine airfoils and airfoil tooling?
*sigh*

Da Crew,
(These suggestions have been mentioned already but.. I'll add to help)
The best way, imho, is to open a new file and...
Insert/Shared Data/Copy Geometry from Other Model/Open (the imported
iges proe file)/Default (coordinate system)/Surface Refs/Include/Indiv
Surfs or Quilts.. (now you have the surfaces you want)
Otherwise, if you want to keep the data all in the same imported iges
proe file:
Add all the imported surface geometry to one layer, then,
Insert/Surface/Copy the surfaces (or quilts) you want, then Blank the
layer with all the imported surfaces. (now you have surfaces you want)
Good luck..

We are running Wildfire 2.0 build M010, but have received M030, but haven't

Yes, turbine airfoils. Pro/e can do a great deal of different types of
work. We're not building Lego blocks, as I told our WF2 rep, but we'd like
to get into contact w/someone that may have the unique perspective of using
WF2 in the turbine airfoil industry specifically with investment casting

Cool. Can't help ya. Google search for:
aviation OR aerospace turbine tooling pro/e OR pro/engineer
might get you a start. Might also get your sales rep to put out some

Through my current employer I've done a good deal of work for Solar Turbines
in San Diego. My stuff has mostly been tool design, but the tooling I do has
to interface to the Solar's parts, which have a lot of various airfoil
shapes. They don't do aircraft engines; their turbines are built for power
generation and oil/gas pumping stations, but it probably doesn't make a lot
of difference from your standpoint.
I won't be able to help you with WF2-specifics: Solar (and, therefore, we)
is on WF still. But it shouldn't make a hell of a lot of difference, either.
For your purposes it would be the best if your Wildfire rep could get you in
touch with people at Solar. However, don't hold your breath: they are
extremely security-paranoid (with good reason). On the other hand, if there
are any software-related questions I can answer without sharing their
designs, I don't see how this will violate our NDA with them.
You can email me at removealex.shishkin@sbcglobal.net (minus the 'remove'
thingy).
