Path simulator bug?

Giulio Buccini · Post by **Giulio Buccini** » Sat Jul 10, 2021 9:15 pm

I was just playing with the "Linear2D" array command to duplicate some circular pockets on a plane.
I noticed that if I try to simulate the path then only the milling ops on the first pocket are executed, the other pockets are ignored.

I missing something?

Afternoon from the sunny state of Oklahoma in the United States of America. I am taking a look at your file and the issue you are reporting. First test confirms your reported issue. I am now looking into the code for the cause.

Me again.
The problem appears to be that the `Array` object lacks the `Active` property that other operations possess. I will see if I can identify a proper solution for this issue. Feel free to create a bug tracker ticket for this issue.

I currently have an open PR that refactors the `PathArray` module. If I identify a solution to this issue, I may append it to that PR.

Thanks for reporting the matter. Have a great afternoon.

Hi Russel, 3:30 AM here in Germany.

Anyway the generated g-code seems ok to me. So it seems a problem of the simulator only. Can you confirm?

P.S.
Following the link you posted I read: "IMPORTANT: POST ONLY 0.19 BUG REPORTS"
I'm using version 0.20 ...

Good early German morning!
I can confirm the issue is isolated to the simulator.

I have added a simple fix, adding the `Active` property to the Array object, to the existing PR #4818, [Path] Refactor path array algorithm into independent PathArray class. I tested the fix and it does allow the simulator to include the Array object in the simulation. I also added the Path Array operation to the recognized list for the `Active` toggle in the Path WB toolbar since it will now have the dependent `Active` property for the toggle process.

The bug does exist in 0.19 also. You are simply a very astute individual that uses the latest and greatest version.

Have a great day. Thanks for making FreeCAD better.
