section view and new version [solved]

[Vincent B]

The section view seems doesn't work anymore with this version.
Somebody to check out that?

Probably the reason you've had no responses up to now is no-one else is seeing the fault you describe. I created a brand new Techdraw page using my favourite test model and applied two section views with no errors in the Report View. The community seems to be experiencing quite a number of config file issues possibly with a number of users having 0.18 and 0.19 but using the same config files for both. I would never recommend this and therefore have a batch file specifically for 0.18 and another for 0.19. So therefore it's worth trying a rename of your user.cfg and system.cfg with FreeCAD closed, please give feedback whatever the outcome.


@wanderefan I am looking at a possible bug in the orientation of certain section views but I'll report that separately when I've done further testing on Linux as well.

You're right. After have installed the new version of freecad, I saw the default repertory files (hatch...) was not good and must be right filled out.

I'm seeing the same (or similar) problem on Linux. It's strange but the problem seems to raise its ugly head for me when I modify the TechDraw workbench's settings then restart FreeCAD.

Steps to reproduce:

1. rm -rf $HOME/.FreeCAD
2. Start FreeCAD
3. Create one or more section(s) through a part
4. Save and exit FreeCAD
5. Restart FreeCAD and open model
6. Create another section through a part (to show that it still works but it's not absolutely necessary)
7. Modify the font in TechDraw preferences (I use Open Sans)
8. Exit and restart FreeCAD
9. Open the model
10. Attempt to create a section through a part - it fails at this point (The error message is: File /tmp/FreeCAD_Doc_a59905d2-2c78-4920-9fab-7ddd51b3da39_bab6ba_135044/FreeCAD_Doc_a59905d2-2c78-4920-9fab-7ddd51b3da39_bab6ba_135044SectionView004SvgHatch.svgBsMZ2B does not exist.)
11. Save and exit FreeCAD
12. rm -rf $HOME/.FreeCAD
13. Restart FreeCAD and open the model

You should see a SectionView item in the Model View that is not associated with the ProjGroup where all the sections were successfully created. The SectionView I'm referring to is called SectionView003 in the attached model.

I have attached the model that I used.

Haven't managed to duplicate your results so far, but I'm using a version that is 120 commits ahead of yours.

I've seen that message in the past, but not lately. There was some work done on managing the svg files for hatches, so maybe the problem doesn't exist now?

Thanks for letting me know your experience. Based on your feedback I decided to download the "latest" appimage as at 16-Jun-20, but unfortunately the problem still exists as I described it. As soon as I changed the TechDraw font and restarted FreeCAD the problem raised its ugly head. Looks like I won't be changing the font...at least until the "latest" appimage is at least at the same revision as your version. (At this stage I don't have the time nor inclination to build FreeCAD from scratch but maybe in the future...)

Hope this may provide some clues to the current "section" problem in techdraw.

Try:
New file>Part>cube>techdraw>view>section

Result:
- Section Tasks tab is greyed out, and doesn't function:
- No section view is generated.
- Console and report output are output are as follows.

This is what the dialog look like before selecting an orientation (large bluish buttons). Once you select an orientation, the data entry fields should become active.

This says that third and fourth SectionView objects are being added to the document. There is no sign of them in the tree or on the page? Are "SectionView" and "SectionView001" in the document?

This has been reported before with the AppImage version, but I can not duplicate it here with this:
