I agree. That would be my preferred workflow.
In example @looo made that seem possible. Maybe over time you two can figure out if something is still missing in Pivy, to make that more streamlined. I guess now it should be a bit easier. As there is an additional developer leveraging such capabilities. ;)
Sorry for that. I am currently in a delicate situation where I can't compile FC anymore. So I use a PY3/Qt5 Appimage, but I cannot test other builds. Would you have a console log of the crash please ?
There is Py2/Qt4 AppImage available too, said that, it doesn't crash. This therefore feels like some glitch on my system and as such i don't feel it makes much more sense to look into it further. I have a newer, compared to the default, Pivy installed and likely there is an issue involved related to that. And in the end i am not sure on how Python 2 compatible the latest Pivy currently is or intends to be in the future.

The editable interpolation curve tool should now work also with pivy 0.6.4
I think it works quite well to model hulls, wings, etc ...

This looks great. I'm looking forward to modeling the mud wings of a prewar car ...
You need at least FreeCAD 0.19.23300 to edit my current sketches.

Hi Chris,
that is what I get after invoking your code => some utils missing?
Old python. Why doesn't it update when downloading actual 18-pre versions?

Code: Select all

Python 2.7.14 (default, Feb 28 2018, 16:59:39) [MSC v.1800 32 bit (Intel)] on win32
Type 'help', 'copyright', 'credits' or 'license' for more information.
>>> import graphics
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:\Users\Max\AppData\Roaming\FreeCAD\Mod\Curves\graphics.py", line 2, in <module>
    from pivy.utils import getPointOnScreen
ImportError: No module named utils
>>> from graphics import COLORS

Thanks.
Your pivy version is too old, unfortunately.

I think the standard builds are still py2/qt4.
The Conda builds are py3/qt5, but they are only for x64 (you are using 32 bits FreeCAD).

Yes. GeomInfo tool give information about the underlying geometry of an edge or face.
Here, you get information about the full circle that supports your edge.

Hello, i'm trying to use the interpolation curve tool.

i understand keyword shortcuts need, but it's not clear for me how to use the tool with external shape. Is someone can do a youtube video to see the toll in action ?

My "learning curve" could be better :-) thanks !
