Hi everyone !
Today I was playing with shapes and extruding them and I found that the X and Y coordinates are inverted…
Maybe I do something wrong… Here is my “playground”

Thanks 
Okay, with further investigation I’ve seen that on extruded shapes the maeh is rotating 90 degrees.
Here is an example. Just exchange the mesh and the geomety to see how it’s changing.
