Bug in Path/Pocket 0.19

[scholli]

I found a strange behaviour in the latest daily (which I could not find described anywhere yet).

When I try to create a pocket operation the basemodel jumps out of it's position (even kind of random as it seems)

I attached the test file with which I was able to reproduce it...

Hope that helps finding the root cause an fix it.

When I try to create a pocket operation the basemodel jumps out of it's position (even kind of random as it seems)

Yes, this is currently broken - it happens whenever one repositions or rotates the base model. Unfortunately the fix is not straight forward and will probably take a bit.

I attached the test file with which I was able to reproduce it...

Here it is even worse, perhaps due to the fact that openCamlib isn't installed:
After a fresh FreeCAD start and loading the model I get the error in report view

Code: Select all

OpenCamLib is not working!

A recompute shows the message

Code: Select all

PathPocketShape.ERROR: Pocket does not support shape Model-Body001.Face11

and then the path vanishes completely.

Evening,
I am taking a look at this issue. I have downloaded the model file in the OP. I have identified one problem in the model file. I have not been able to reproduce the result in the model file, yet. I will also test with earlier releases when I have additional time. I will provide more information and solution when it is not so late here.

Stay tuned,
Russell

Hi Russel,

Do you need a step by step to see where the error occurs?

I can reproduce it...

Edit: Wait, i am download the newes version of FreeCAD...

Evening,
Thanks for the instructions above, Walter.

Ok with: ... Start here: ... Now we see this: ... PathPocketShape.ERROR: ...

Using them, I was able to reproduce the error and trouble-shoot the problem.

I found a strange behaviour in the latest daily (which I could not find described anywhere yet).
When I try to create a pocket operation the basemodel jumps out of it's position (even kind of random as it seems)

I collaborated with @mlampert and have corrected the issue. ...Well, at least the current model works correctly. However, I have since made additional modifications to the same files to accommodate rotational UI elements. So, I have two options:

1. wait to present the solution as a part of my next PR
2. use the current scripts to make patched versions with only the necessary changes to address the issue identified in this topic - then upload to the related topic here on the forum

If I get time, I may opt for making a patched version of the current script. This would help FC users sooner. Besides that, I don't have a time frame for my next PR with 4th-axis UI integration.

Thanks.
Russell

Morning,

I found a strange behaviour in the latest daily (which I could not find described anywhere yet).

When I try to create a pocket operation the basemodel jumps out of it's position (even kind of random as it seems)

Okay. I reworked the script. So far my tests show this behavior to be eradicated. Further testing will confirm or disprove the fix... lol.
I appreciate the testing and feedback.

Please visit the Path Pocket Shape: 4th-axis Integration topic to download the updated scripts to fix this issue. You will need to re-create your Path Pocket Shape operations because the "Use Rotation" property has been renamed to "Enable Rotation" in preparation for UI integration of rotation settings within the core of the PathWB.

Thanks Walter for the help in reproducing the error.

Yes, this is currently broken - it happens whenever one repositions or rotates the base model. Unfortunately the fix is not straight forward and will probably take a bit.

I think it is fixed, unless there is another issue to which you were referrring? I ran a couple tests on the two instances of this problem reported here in the forums and both models and operations behaved correctly with the fix. I have this fix already in my 4th_axis branch - had to edit it in order to remove UI elements I had installed also. Stand-alone version 1k-testing is available now at the topic linked above. Feel free to visit my GH repo and build the 4th_axis branch that has Rotation UI integration for PathWB well started.

Shall we mark as solved based on Russ's new published python scripts?
