ksuToolsAddTracks fail #195

myamigo · 2023-11-10T15:27:08Z

Description

I have a fairly complicated PCB (8 layers, 805 components) that I am importing into FreeCAD using KiCadStepUp. The "Load Board" command works fine and finishes in about 1 min. When I move to "Add Tracks" I hit a fault after a little more than 1 hr...

10:13:27  zones done
10:16:29  running time: 3850.488sec
10:16:29  running time: 3853.867sec

10:16:29  Running the Python command 'ksuToolsAddTracks' failed:
Traceback (most recent call last):
  File "C:\Users\scott\AppData\Roaming\FreeCAD\Mod\kicadStepUpMod\.\kicadStepUpCMD.py", line 4352, in Activated
    add_toberemoved = tracks.addtracks()

    FreeCAD.ActiveDocument.getObject('Board_Geoms'+tname_sfx).addObject(extrude)

<no object bound to built-in method addObject>

The fault occurs while processing the top layer.

Given how log it takes to get to the fault I worked on getting the file size down to narrow focus and managed to isolate it to an edge case, literally.

I have a castellated edge connector in my design to which I attach a Tag Connect EC-10 edge connector adapter. The board edge should run down the center of the holes, splitting them in two as shown below...

If I move the board edge so it clears the TC_EC-10 pads (Y=0.64mm) then fault does not occur...

If I set the bottom edge of the board to Y=0.63mm then the fault occurs.

Steps to reproduce

Save StepUp_Issue#195.zip file to a folder and extract the board file.
Run FreeCAD and enabled the StepUp WB
"Load Board" then "Add Tracks"
Verify fault
Edit the board outline and set the lower edge at 0.64mm
Repeat step 3 and verify that there is no fault
Edit the board outline and set the lower edge at 0.63mm
Repeat step 3 and verify that there is fault again

@myamigo
thanks for the detailed feedback.
I tried your board but I cannot reproduce your issue...
I get only this warning message:
Part::Extrusion: Link(s) to object(s) 'Sketch' go out of the allowed scope 'Extrude57'. Instead, the linked object(s) reside within 'Board_c493'

StepUp_Issue#195-castellated-kv7.zip
I downloaded FC from here:
https://github.com/FreeCAD/FreeCAD/releases/download/0.21.1/FreeCAD_0.21.1-Windows-x86_64.7z

Your issue and FC error seem similar to this issue #179

As a side note, please consider to add Grid origin to your kicad_pcb file... then all your sketches in FC will be aligned to this origin.

myamigo · 2023-11-11T14:23:21Z

Hmmm. What version of KiCad are you running? I prefer aux=drill origin so the PCB lines up with other mech models.

myamigo · 2023-11-11T14:29:15Z

That error mssg with sketch out of scope seems to be relevant. Does the mssg go away when the board outline is extended past the part?

easyw · 2023-11-12T11:08:14Z

Hmmm. What version of KiCad are you running? I prefer aux=drill origin so the PCB lines up with other mech models.

you can choose aux=drill origin as you prefer,
but then you have to set in FC kSU pref the same.
Then FreeCAD and KiCAD will use the same reference for mech objects

in kicad v7 grid origin is hidden under long click on aux origin icon

Thanks for the tip!

I solved my "no object bound to built-in method addObject" problem at line #238 of tracks.py

I changed that line from:

        FreeCAD.ActiveDocument.getObject('Board_Geoms'+tname_sfx).addObject(extrude)

to

        try:
            FreeCAD.ActiveDocument.getObject('Board_Geoms'+tname_sfx).addObject(extrude)
        except:
            print('EXCEPTION: Board_Geoms'+tname_sfx+'.addObject(extrude)')
            pass

And it happily gets by. I don't know exactly what is going on under the hood but I expect the edge connector is getting split into two zones groups with one being associated with the board because it is inside, and the other is left as an orphan. This change seems to handle the orphan.

This got me by that issue and on to another one involving net-ties that I will create another issue for.

Thank you for your help and a great FC add-on.

@myamigo
please test the board with the new update 0f8c4d5 ...
it should solve the issue and keep the cut for tracks.

myamigo · 2023-11-13T15:47:15Z

Confirming that your update gets by the issue. I'm testing it with my larger PCB now and I'll report the result. I'm also using the grid origin after setting it to the drill origin (PCB center).

myamigo · 2023-11-13T18:41:19Z

The larger PCB import completed and it looks much better but now I am noticing problems.

There is a large rectangular "pad" that is the size of the overall GND pour included with the topPads face but it is located at the design origin (0, 0) where the grid origin is now at (200, 100).

If I Draft | Downgrade the face I can select and delete the rectangle. Then I can select all of the downgrade shapes and Upgrade them gain I have what I expect... almost!

I am noticing random instances of pads missing...
Here is a 12x12 BGA in KiCad...

... and after the FC_ SU import...

... that is mostly showing a 9x9 pattern.

This show show 2 pads and a net-tie (highlighted) ...

The ISP_BOOTn pad and net-tie next to it are missing in FC as is the footprint below...

In another spot I see a track area that has not been completely constructed. ...
In KiCad...

When imported...

Several pads are missing in this view and the highlighted rectangle does not have a outline like the other objects. I think I can work with the output now so I can export to STEP an load back into my CAD package for assembly fit and rendering.

I am willing to try anything you might suggest but I have to get back on track.

myamigo · 2023-11-13T19:38:23Z

I may be seeing more issues with the use of complex pads as I note in #196 (comment)

I'll report what I find.

easyw · 2023-11-13T22:13:45Z

If you are looking for rendering, you may look for kicad to blender plugin.
To get assembly checking, missing some pads shouldn't be an issue at all.
The main purpose of kicadStepUp is the mechanical integration and tracks are added just for this scope.

myamigo · 2023-11-14T15:44:26Z

I've not looked at Blender yet but I will. I'm also looking for high quality renders of our product with the PCB in exploded view so our pro CAD package is best for that. Anyway, I'm getting closer to a solution.

myamigo · 2023-11-15T20:56:48Z

My issues have been addressed with updated FP's as per #196.
