Hi mike, for drawing on surfaces just make sure to enable "Object Snap" in the bottom toolbar so that it's highlighted in orange. When it's enabled there will be an "on surface" snap that will place the current point onto a surface. And if you want the object that you're drawing to follow the direction of the object that you placed the first point on (like drawing a rectangle directly on the side of the cube), make sure you are placing those points inside of the 3D view, not the Top/Front/Right views. When you do the drawing in the 3D view it will automatically align planar drawed objects onto the surface you are placing points on, when you're in the 2D Top/Front/Right views it keeps the drawn object flat to that 2D view.

For some more information and small example video captures, check out here:

look for the section labeled "Drawing / snapping on to surfaces".

Hi Michael,

Actually I got as far as your animations show. I thought it would project too. I mean draw completely on the surface. No biggy I just used the curve projection tool to take it further.

Hi mike, no those drawing tools like circle, rectangle, etc... are designed to draw planar objects. If it was automatically projected onto a curved surface you would no longer be getting an actual circle or rectangle result from the circle or rectangle commands for example which would be kind of weird, and make some kinds of things like inputting a radius to be very misleading since the actual result you got would not actually have the radius that you just specified. It just keeps things a lot more simple and predictable when the circle command really does make circles instead of making something else.

If you want the result to be projected you'll need to do the projection afterwards yourself. But one other thing to note is that several commands like Trim and Booleans will automatically project planar curves just as a built in part of the command, so if you're planning on cutting with the drawn curve you don't actually need to do a projection of it as a separate step, just do the boolean or trim with the planar curve directly.
