Snapping to a point on an arc.

[Anonymous]

Might be a dumb question but is there a way to snap this circle to the 3o'clock position of this larger circle? My work around was to horizontally constrain the center of the circle to the center of the bigger circle but I don't really like that...

I came from NX11 and MasterCAM and they have snap on by default.

Horizontal snap constrain

Related question: Is there also a way to snap to midpoint?

Thanks!

Thanks For Posting your Problem in Autodesk Forum.

Yes, In Autodesk Fusion 360 have a way to snap to mid point of circle.

when you draw a large circle then it has a centre point, 

next you select circle command then you go on the center point of large circle and take a reference & move your courser in vertically & horizontally.

At that time you draw on circumference of Large circle according to Reference.

You can, as mentioned above, move your cursor over the centerpoint of the larger circle first, then move it towards the 3-c'clock position, giving you a reference to snap the smaller circle onto. But it won't constrain there. It will constrain the smaller circle coincident to the diameter of the larger circle, but it won't constrain its position on that diameter.

You'll have to establish some other constraint. The simplest is to give the centerpoints of both circles a horizontal constraint together, but there are other ways too. All of them involve establishing at least one constraint. Fusion doesn't just "know" that you want it locked there.
