Hi, i am new to this fusion 360. I met problem regarding the issues of projecting line on the surface. I can't project the line onto the sphere surface and it is really frustating.
The warning shows **Not support projecting sketch geometry into same sketch,please change the target sketch or geomery**. I dont understand, somebody help me explain why this happened. ;(
