how do I get the center of mass symbol to show in drawing views
Actually, Glenn. That is just step 1.
Step 2 is to physically show it because it is hidden by default.
You need to select it in the tree and show it.
I don't know. Here's what I do.
I downloaded a macro from this forum called CenterOfMassPointCreation.swp . It creates a 3D Sketch and places a point upon the CoM. Note I did not write this attachment.
In drawings, I have a CoM symbol created as a block. I drop this into the view, and make it coincident with that visible point in the sketch. Then I hide sketches.

How to add a point on CENTER OF MASS
First insert reference geometry COG in part/assembly.
Second, insert model items in drawing.
You might need to make COG visible.
