Unwrap error

[Mx74]

Unwrapping was working so far, but since the 2 last updates:

float() argument must be a string or a number, not 'NoneType'Running the Python command 'PatternCommand' failed: Traceback (most recent call last): File "/miniconda3/envs/freecad/lib/python3.9/site-packages/freecad/freecad_glider/tools/init.py", line 167, in Activated pat.unwrap(file_name, obj.Proxy.getGliderInstance()) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/patterns.py", line 157, in unwrap super().unwrap(outdir) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/patterns.py", line 112, in unwrap all_patterns = self._get_plotfile() File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/patterns.py", line 89, in _get_plotfile plots.unwrap() File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/glider/init.py", line 164, in unwrap self.get_ribs() File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/glider/init.py", line 84, in get_ribs rib_plot.flatten(self.glider_3d) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/glider/ribs.py", line 228, in flatten return super(SingleSkinRibPlot, self).flatten(glider) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/glider/ribs.py", line 83, in flatten self.draw_rib(glider) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/plots/glider/ribs.py", line 250, in draw_rib single_skin_cut = self.rib.profile_2d(singleskin_cut_left) File "/miniconda3/envs/freecad/lib/python3.9/site-packages/openglider/airfoil/profile_2d.py", line 49, in call xval = float(xval)

I made a simple test:

• new doc, I create a new glider by default: unwraping works
• I name a line or a riser : unwraping doesn't work anymore.
• I delete the name, unwraping still doesn't work. So it seems it has something to deal with naming those lines

I can't reproduce on linux/ubuntu.

btw. please use ```code``` for code blocks.

I'm also on Ubuntu. Made another test on Manjaro, same problem. Both are installed via Conda.

I just made the naming test again, the error message is a bit different:

These two different errors made me wonder...

I just copied all the openglider's files again over the existing ones, and now it runs smoothly. Don't know what has happen when I updated the last commit, but obviously something went wrong. Sorry for the hassle.
