Very new to fusion 360 ! When I add a circle tangent to 2 other circles it moves the first 2 circles from

their original locations. Do they need to be contrained?

Thanks

If you do not want them to move, YES. All sketch entities should be constrained and related to the Origin of the model. In your case, dimensions, to the circle centers from the origin and/or each other will be the answer.

Here is a quick Screencast showing what I wrote about above. I assumed the circle you wanted tangent but it can be any of the three.

I did not explain very well, Sorry . I wanted the 2 circles with dimensions to not move

and the 3 rd. circle on the right to move only.

I know there is a way its great software!

Thanks

Same solution method, just apply the dimensions to the circles you do not want to mover, constrain them, and then apply the tangent constrain to the other circle.

The reply you gave was right on I am back to designing . Can not live with out those constraints !

Thanks
