FLÄCHENMODELL PERFORMANCE

Hallo Inventorianer,
wir haben Daten aus Catia V4 nach Inventor 7 konvertiert (ca. 35 MB). Welche Möglichkeiten gibt es die Performance auf ein erträgliches Maß zu erhöhen? Drehen läßt sich das Modell super schnell.

Aber schon eine Extrusion dauert ca. 2-3 Min!!

2GB Arbeitsspeicher, P4 2,8 GHz., Windows XP Pro SP1. Grafikkarte 3dlabs 7110

Vielen Dank

Georg

Yea right

 

I don't know much of Inventor yet, but if you ask
in English I'm sure you'll get more answers.

 

 

Danke

We are having data convert from catia 4 to IV7. Something about super slow model, rotation and extrusion. Thats all I can get out of it. A 35 mb file is a pretty good sized file to import though.



What format are you importing the data in. IGES, STEP?

Data from Catia V4 converted hello Inventorianer, we after Inventor 7 (approx. 35 MT). Are
there which possibilities to increase the performance to a bearable measure? Tricks leaves
itself fast the model super. But already an extruding lasts approx.. 2-3 min!! 2GB main
memory, P4 2.8 GHz., Windows XP pro SP1. diagram map 3dlabs 7110 Thank you George

That takes the fun out of it Kent. What use is the Deutch I took in highschool if I can't show how little I retained here!

Hello Inventorianer, we converted data out of Catia V4 after Inventor 7 (ca. 35 MB). Which possibilities is there, to raise the Performance to a tolerable measure? Turning lets itself the model super quickly. But already an extrusion lasts ca. 2-3 min! 2GB memory, P4 2.8 GHZS., Windows Xp per SP1. graphic card 3dlabs 7110 thank you very much Georg

I convert data from Catia V4 to Inventor (surfaces). I use the STEP Interface. The rotation of the model is very fast.But if I would like to make any changes it takes about 2-3 min. How could I increase the speed to seconds?

Best regards Georg

Hey thats the best xlation yet!



Clearly the file is too large to post. Is this just a single part? If so you might have kernal errors that are causing the problem. Otherwise I would have assumed imported data would be fast since the beginning brep data is fixed and thus shouldn't need any calculation. Sean is going to give me a hard time about this, but save the file as an acis file and open it with MDT and do an amsanitycheck. Warnings are OK, but if errors show up that would most likely be the cause of your problem.

The problem is the surfaces.  Thickening
them?  Takes forever!  Catia export only surfaces, to other cad
programs.  Probably used Elysium?  I would suggest exporting to
another program.  Maybe Rhino and then making a step model to import into
Inventor!!

You can also look at having CATIA surface quality
no higher than 5 as well as cleaning up unnecessary operations.

the surface is closed = body

We have Catia V4 and Inventor 7 here... we
perform these translations daily. Once you STEP the data into Inventor you
should see construction surfaces. Using the promote tool, right click >
select all. Now promote, if the surface is in fact a closed body Inventor will
promote it into a solid.

 

Mind you, 35MB is a large file. I am
currently working with somethign similar and it still takes a while to load and
manipulate.

Do you need the complete body? Or just some pick-up
points? Maybe you can open the body, add the work geometry you need and then
make a derived part of it using only the work geometry. Next, use the derived
part to model your assembly around it. When you're done switch on the body in
the derived component.

Like I said, I'm not a CATIA expert, far from
it.

 

I have, however worked with CATIA files, and one of
the things we did was have the people working CATIA clean up the file and use 5
as maximum surface quality.  That helped translation to the extent that the
import is now completely workable.

 

The fact that the body is closed had nothing to do
with the fact that there was cleaning up to be done.

 

It's up to you.

Yes I need the complete body.

The performance is horrible. Why does Inventor convert the STEP-files so badly?
Other programs convert this much better e.g. MDT.

I haven't seen this phenomenon but then again I don't import files on a daily basis. From what I have seen all the packages have quirks, granted IV is one of the worst on importing. SW is weird, it pretends to have healed the model but if you export it out again and import it you will get the same problems again. It is almost like SW healing is really just learning what to ignore. PTC does a good job of importing if you get all the settings just right AND the part doesn't have an outlandish aspect ratio.

Okay guys. Let me give this a try.



George,



Versuch, Ihren Softwarenfahrer für Ihre Grafikkarte zu aktualisieren. Sie macht irgendetwas haben, das in der Hintergrundumwelt läuft. Wenn doch dies kann wirklich die Leistung hinunter verlangsamen.

Drivers are all updatet. It´s not a hardware bug. It is a bug of Inventor. The same import in MDT 6 is ok!! and I can work with the model!!

The biggest model I ever had was about 250 MB. This model does not make so much problems (no drawings)!! It´s not the size of the model. It is the STEP-interface.

best regards

You should then be able to acisout of MDT and import the kernal data into IV and be good. Meahwhile you should have your VAR (reseller) submit the STEP to Autodesk for analysis.
