Concern about extruded holes

[hoosac19]

Hello,

I created a hole in the bottom sketch of my housing, but have some questions:

1) I extruded the first hole in my sketch and copied it, but neither hole shows any depth in the 3D view (photo shown) unless I set the housing opacity to less than 100%.

2) If I select edit mode for the bottom sketch, only the first hole circle appears, not the copy (photo shown).

3) I really want to snap new hole copies to the intersection of the inner construction circle and the straight construction lines (90 degrees apart) (see 3D photo), but I see no snap at these coincident intersections and instead have to zoom in by a factor of 10-100X to be sure that the hole center aligns properly.

4) If I rotate the 3D view to the bottom face (orthogonal), I can click on the center of the original extruded hole to verify its Cartesian coordinate, but the copied hole displays no center mark (see photo).

Thank you very much for your help!

Well your hole/s are studs, and therefore you won't find any holes.

If and when you make a extrude hole and thread it, you will be able to pattern it, rather than move.

Might help....

Ok, I deleted the holes and reconstructed them and am now certain that they are holes and not protrusions.

I've tried several times to use the move/copy tool to make a copy of the top hole, first by selecting the hole face (first photo) and then by selecting the hole sketch (second photo).  In each case, there is only an option to move (the copy checkbox is either absent or greyed out).

What is the correct method to copy a hole in this case?

I can use copy and paste to duplicate a circle in 2D sketch mode, but unfortunately all the construction lines disappear (unlike in 3D mode), making hole placement difficult.  I made sure that the separate sketch layer used for construction lines is set to Visible.

Does Fusion 360 support "snap to construction line intersection" capability (in this case, between a circle and a straight line)?

Thank you again.

What I would do.....

You didn't say how many holes, but half circle with 45 degrees spread, in this example....

Might help....

Thank you for the circular pattern suggestion, I've been using it and the rectangular pattern tool to copy my extruded holes in lieu of the straight Move/Copy command for now.
