Imported F3D object is broken

[kmarty]

Hi again, at this moment I am able to import F3D file .

but either I choose "Convert to STEP" or "nativ" ("Native"?), I get this:

with "Report view" output:

F3D file: Cable_holder_E3_v113.f3d or: Cable_holder_E3V2_v3.f3d (both does the same or very similar result)

This is how it should look (this one is imported STL -> "Create shape from mesh" -> "Refine shape" -> "Convert to solid"):

BTW. Is it ok that after import a (temporary?) folder with the same name as F3D file remains next to F3D file?

[jmplonka]

Hello,

the ACIS (SAT, SAB/SMB[H]) import is not easy to process for me. The result doesn't look like what is expeted and I don't understand why.

PS the folder contains the Content of the imported file for debugging purposes. Like the SMB/SMBH files for the F3D files, together with the converted SAT and / or STEP files.

[kmarty]

I get it. It's just a report.

Temporary directory/folder: I see.

[jmplonka]

Unfortunately I can't figure out why the plane is not well alligned. Importing the points from the resulting SAT file as point-cloud it looks the same. Nither Inventor nor Fusion360 is able to import the SMB file LOL.

[kmarty]

So, the issue is there, it is not resolved, but closed anyway? Huh?

"I don't know how to fix it (, yet)" isn't reason for closing the issue.

Btw. the original F3D file was created in Fusion360.

[jmplonka]

Please, do me a favour: have a look into the ~_f3d folder and open the ~.smbh file in FreeCAD with "Convert to STEP". Is it possible for you to open the file, or does FreeCAD crashes (QT5-Conda issue ?!?)?

[kmarty]

Step by step (just for sure):

• Open FreeCAD
• update "InventorLoader" plugin:

Workbench successfully updated. Please restart FreeCAD to apply the changes.

- restart FreeCAD
- download "Cable_holder_E3V2_v3.f3d"
- import "Cable_holder_E3V2_v3.f3d" in FreeCAD with "Convert to STEP" (which creates temp folder with SMB and SMBH files)
- ignore how looks imported model (corrupted, btw)
- close FreeCAD without saving
- open FreeCAD
- import SMBH file with "Convert to STEP"

but it look, for first sight, fine. No crash happened in any step.

So there seems to be a big difference in SMB and SMBH files and I will switch to SMBH instead! Thank you very much for your support.

[jmplonka]

For a better understanding of the F3D files, I'm working on a feature based ('native') import routine for Fusion360.
