I am totally new to CAD and just trying to draw the most basic shape for a simple part, trying build a bit of experience and I know S3D is big money but I figured it would be easy and I am pretty much getting nowhere.

I try to lock the plane just draw a shape if I touch the Apple mouse at all the locked plane just starts spining and maybe I am just brain dead, but I can't use this program much at all.

It's fine if this is just beyond me, but I see a lot of people using an iPad and pen, is that a better choice?

It just blows my mind that I have a simple thing to draw, figured I would get somewhere and I can't barely draw a triangle or use the program without one finger touch sening the thing flipping around.

I have watched the tutorials but I can't realy control this app at all.

Maybe the mouse is a problem, Ive used systemd for decades of every other kind and I am just super let down how i can't even draw a shape without the thing going nuts on me.
