TIG, I guess Tyuro wanted to draw on the face of the circle (2D) not on the surface of the cylinder (3D)

Thats correct

Awesome! It worked! Thank you very much

Hello,

I'm new to sketchup. I've experience with Solidworks.

Now i wanted to draw a shape in sketchup on the same plane as the little circle... Now each time I want to draw something it comes on the plane of the cuboid... How can I select in sketchup that I want to create a drawing on the same plane (surface) as the little circle...
