I would guess there is no error. I had the same problem when I worked on my Jupyter integration.

I think the problem is that showMainWindow doesn't start a QT EventLoop anymore. Earlier FC versions did, and so that code worked as is.

Yes, I did exactly that and had the problems mentioned above.

I'd like to import STEP files through the Python API. The only way I found so far is "Import.import". Side Note: "Import" is a legal name for a module, but maybe not the most appropriate... But that function always returns None. It creates a new document with one object. You can ...

For example this works well: templates = [] ell = Part.Ellipse(vector(0),5,4) template = ell.toNurbs().toShape().Edges[0].Edges[0] obj.Shape = template for i in np.linspace(0,10,int(10/0.2)): templates.append(template.copy()\ .translated(vector(0,0,i)).copy() .rotated(vector(0), vector(0,0,1), i / 4...

Yes, that helps I think, thank you!

I also think I need to be more careful what Objects to pass into the Loft. Not everything that looks like a wire is an edge.

No, I don't think my shapes intersect. The edges of each layer are touching to form a closed wire, but the layers don't touch each other.

I'm using the latest development version installed through Conda on Ubuntu. I'd like to rotate and extrude a 2D Shape through Python. I have tried several Shapes as a combination of wires whose Edges are toching (Lines, Arcs etc). I have tried putting those Edges in a List,a Compound and a Wire. I m...

The following trick works (after %gui qt):

Interstingly though, if I start a jupyter kernel in that environment, this code will open the main window: from PySide2.QtWidgets import (QLineEdit, QPushButton, QApplication, QVBoxLayout, QDialog) import freecad import FreeCADGui as gui %gui qt5 The next line must be in a new cell. gui.showMainWind...

I followed your instructions, and installed a conda environment on two different Ubuntu systems. showMainWindow from a python script (no jupyter involved) briefly shows a black window and crashes with no error message. No idea why. I'd like to promote Jupyter not just for core and addon developers, ...
