I discovered uMake+ for myself yesterday and immediately subscribed - a fantastic tool.
However, the current version 3.49.1 seems to contain a massive bug concerning the Sketch Planes:
Whenever I create a Sketch Plane and then click on the hook at the bottom right to activate it, the Sketch Plane immediately disappears and the grid immediately moves back to the position of the original XYZ axes (red, green, blue).
This always happens even if I lock the Sketch Plane. So no accurate drawing is possible.
Am I doing something wrong or is this really a bug in the current version? I have watched several tutorial videos on YouTube and followed the instructions exactly - so I can hardly believe that I have misunderstood a function here.
