[solved] Value increase error: editing 3D Surface changes values all by itself

[chrisb]

i set the values for BoundBox extra offset and Sample Interval to 1mm and close the UI by clicking OK

I can confirm herb's observations, but there is more in it: When I load the file I get the following error message in report view:

Code: Select all

Traceback (most recent call last):
  File "/Users/cb/Desktop/FreeCAD.app/Contents/Resources/Mod/Path/PathScripts/PathOp.py", line 227, in onDocumentRestored

    obj.setEditorMode('ShowTempObjects', 2)  # hide
<class 'AttributeError'>: Property container has no property 'ShowTempObjects'

Next error on double click on the surface op:

- Deleted Surface op and saved the file.
- After that, loading the file did not show any error
- I couldn't select both surfaces before creating the operation, because they are from different solids.
Error in report view: PathOpGui.ERROR: Please select faces from a single solid
- I could add the second face separately
- When I now change the settings according to herbk's settings I can create the 3D surface.
- Editing the operation I can confirm herb's issue.

... It's not a new problem, a made checks down to Appimage release .19518, the oldest i have.

I think to remember we have had this prob at other OPs/parameters to, but that was several month in the past...

... - Editing the operation I can confirm herb's issue.

Has anyone else experienced this issue?
Same platform, MacOS, or on a different platform?
Using pre-compiled downloads, or compiling from source?

I have not had this specific problem, increase by a factor of 10, on Windows 10 machines, ever that I can recall.

Thanks for the input and testing.

@ChrisB: Should we move these recent posts related to this value increase error to an independent topic here in PathWB, with a title suggestive of the issue?

Thanks,
Russ

[chrisb]

I split the topic, correct me if I did something wrong. Is the title ok?

Hi Russ
I can confirm the problem as described from Herbert and Chris.

Thanks for all of your good work.

Perhaps it is the locale? We are all from Germany having this issue. My locale shows C/C, but I'm not very sure that this is respected everywhere, because that's not my systems setting, it is rather something in the MacOS startup script. I have set the language to English.

Just tried this on my recent linux master but cannot test since the provided model was produced on older 3Dsurface code:

Code: Select all

<class 'AttributeError'>: Property container has no property 'ShowTempObjects'

Maybe OP needs to get latest code to make sure this is not chasing shadows. I can retest if a recent 3D operation displays the same bug.

I will change the lower limit to 0.0001 millimeters in the next PR.

There are a couple of constants for such small numbers in FC. Maybe look and decide which is appropriate. ( Presumably this units relative ) There is the user's geometric accuracy setting and some other hardcoded small number. It would be good to keep such things synchronised, rather than having several unrelated constants dotted around the code.

Happy hunting.

Evening All,

I have noticed the same issue when using the profile edges Op.

Watch the value of extra offset:

We had this a long time ago, and the reason was the erronous handling of the decimal separator. I think that uwestoehr is working on it, perhaps together with openBrain. I will try to find it, but it became very difficult to find even recent posts with the flood we are getting meanwhile per day.
