Can't section imported STP in IDW

I've got some models created in ProE that I made STP files of. In an Inventor assembly, IV10, I can create a section view fine but I can't create a section view of the same part in IDW mode. I know it's not going to work when I drag the mouse to the location I want to drop the section view and I don't get a preview. If I try though, I get the following:

[WARNING] Create Profile And Section View: problems encountered while executing this command. [r:\core\Fw\Main\FWxApp.cpp, line 3724]
[ERROR] Modeling failure while creating edges resulting from face-face intersection. [r:\core\Mi\body.cpp, line 646]
[ERROR] Modeling error while processing 2124875.ipt. [r:\Application\Dl\Main\DLxBodyComputer.cpp, line 968]

[ERROR] Modeling error while processing 2124875.ipt. [r:\Application\Dl\Main\DLxBodyComputer.cpp, line 968]

I tried with auto-stitch turned on and off, with no difference. I also tried exporting an IGES from ProE and get the same results, or lack of results.

I am able to do these same steps successfully in IV11 but the rest of the project is being done in IV10.

Using IV11, I thought to open the STP, save as an IPT, then export it back to STP format again. Anyway, that didn't work either...

I've seen some people mention SAT format and will give that a try as a last resort.

I'm unable to post these parts.

Some maybe's ....

Regen the prt's using an absolute accuracy of .001" or equiv. Resolve any geom
checks that are generated. Try again as STEP or SAT or ...

Shift the section plane a smidge one way or the other to avoid sectioning thru
corner vertices.

Is there interference between the Step'd parts?

That is the most likely cause.

I ended up doing more testing with just the single part file and not in an assembly and it still didn't work.

I can try the absolute accuracy step. As for geometry checks, I did already look and there are more than a few.... It's not my model and I can't invest any time in "fixing" it.

Good idea and it might work. I will give that a try.

That worked .... with some tweaking. If I attempted to place the section line very close to center visually, it would still fail, so I placed it almost an inch away. It works, but that's too far. So, I edited the section line, projected the flange I'm looking at to get the center point, deleted the original section line and recreated a new one. I placed it at .25, then .125, .06, and finally .015 away from center and it works.

Glad you got sumpin workin. I'd have never thought to "sneak up" on it. Pretty
Inventive. `;^)

I'd be interested in obtaining the data set used to see this failure in
sectioning imported data.

Please contact me at: peter.varga@autodesk.com and we can determine the best
way to transfer the data securely.

Peter,

I submitted a part with the same issue under support request #1-887402701.
I was interested in whether or not this part could be repaired with
Inventors surfacing tools. I'm not expert when it comes to surfacing and
hoped for a little more feedback than I got. Please let me know if you
could offer any assistance.
