What moves is not the sketch but its geometry. This happens because all of it is linked to projected external geometry points. They are always projected normal to the sketch so with the changing angle their projections move as well. looks like it's the reason. Then question would be - how to rotate...

Hand-drawing ?

yep, it's hand-drawing. need to build "first approach" model, based only on the common sense.

looks like i don't understand how does geom transformation works. On the following screenshot i created sketch on YZ plane and moving it in Y direction 450 mm, but it was moved in Z direction. Why ???

Hi All, Im beginner with FreeCAD. First of all HUGE thank you for such product ! I've got some issue with sketch placement. Im trying to move my sketch to new position (using rotation around Y-axis), but freecad is shifting sketch a bit, so i can't apply it to generate final body. I have attached my...
