Hi,
There is some work on the path WB related to this issue : https://forum.freecadweb.org/viewtopic. ... &start=210
I suppose it will be fixed soon.

oh dear

is there a way I can access a version 0.19 that isn't broken so I can experiment with Russ's 4th axis code?

I have the same issue on Freecad-daily V0.19 2019/06/10 on Ubuntu 18.04. Freecad 0.18.1 works no problem though...

https://github.com/FreeCAD/FreeCAD/pull/2250

I think that's the fix. Rebuild from source or wait for the next daily build.

I'm wondering if I need to compile my own version to get ahold of a working path in v0.19???

I'd rather avoid this at this delicate noob stage of my freecadding...

oops cross-posted - that's great thanks Sliptonic - I'll wait til tomorrow and try again.

I think there is still an error here:
PathScripts/PathToolController.py#L197
it should be commented/removed:

Code: Select all

# if FreeCAD.GuiUp:
#     # need ViewProvider class in this file to support loading of old files
#     from PathScripts.PathToolControllerGui import ViewProvider

No, this block is essential to keep existing project files loading properly. In existing project files the Python proxy of the view provider saves module name and class name which will be PathToolController instead of PathToolControllerGui.

The line from PathScripts.PathToolControllerGui import ViewProvider makes sure that PathToolController provides the class ViewProvider.

Then there should be something more to be fixed...

I get the following errors after having applied the PR 2250:
