# Center of Mass in F360 - any way to add to sketch?

Has anyone figured a way to easily carry the Center of Mass indicator from the Utilities tab back to a sketch?

I want to be able to use it to position holes for hanging signs. Basically, mark the COM then draw a vertical line to the top and bottom of the sign to position the holes to hold the sign straight.

As far as I can tell, you have to Extrude to find COM, which finishes the sketch.

Can you project the indicator on to the sketch? You may need to create a second sketch as the indicator wouldnâ€™t exist earlier in time.

Iâ€™ll give that a try later today. Thanks for the idea.

I did find this:

So the answer is â€śNo, but yes.â€ť You can set a sketch point to intersect the Center of Mass, but it wonâ€™t dynamically track changes.

Tom, great find, none-the-less. I was going to try and find this. Thanks for doing it.

I was working with this and a sketch has no weight so a hole does not lighten the object in that area.

I know you donâ€™t want to finish the sketch but all you need to do is right click on the sketch and left click on â€śEdit Sketchâ€ť and you are right back in edit mode. When you edit the sketch and then the body, the center of gravity moves dynamically.

Now I cut the second hole and the Center of Gravity moved without me doing anything to it.

Now you decide you want to put holes in-line with the center of gravity so you â€śCreate a New Sketchâ€ť and pick the body. If you close the body out, you lose the center of gravity marker. Now it wonâ€™t snap to the center of gravity but you can zoom in and place a point on the C of G and create a line vertically. I created another line vertically the opposite direction. I then place two 3/8 inch holes on the line.

I delete both of the vertical lines and extrude cut the holes into the body.

The holes are in-line with the center of gravity.

I am not sure if that would work in your application but it definitely needs the body to work.

Wow. I am coming to realize that I havenâ€™t even begun to scratch the surface of Fusion360â€™s capabilities. The things I learn from you guys.

Believe me, I feel I am in the same boat.
