Problem with hole

[Anonymous]

I need to make a recess/pocket to receive the head of a bolt. I have the through hole for the threaded shaft of the bolt in place. When I use the circle command and establish the center and diameter of the recess on the front face based on the center point of the through hole, it shows up on the rear face and therefore I cannot extrude the pocket I need. The front face is curved, not a flat face. I don't see why that would be a problem.

Suggestions?

There is an option, Direction on the extrude dialog set it to 2 sided extrusion, you can drag both the same direction to get what you're after.

I thought of that, but that is not my problem. When I define the larger circle for the recess, it is on the wrong face even though I select the front face and it turns blue. After I establish the center of the circle and the diameter, when I hit Enter, the blue circle that I want to extrude from is on the rear face, not the front that I started with.

I think some pictures will help. When you say circle tool do you mean circle in a sketch?

Yes. New to Fusion and the terminology.

Here is a picture. I need to make recesses with a flat bottom to receive a bolt head. When I define the circle on the outside face, it shows up on the flat face where the slice/kerf is.

You need a Counterbored Hole.

While we are on the subject - I also need a hexagonal hole on the opposite to capture the matching nut. Mind showing me how that is done?

I'd use sketches for this as the hole tool is more work in this situation. Also you should constrain your sketches.

Here's how I'd do it.

This is less work!!??

I have tried for 2 days and can not select the outer circle for my counter bore.

Here is how far I have gotten. Where is my mistake.

Also, what are constraints, what are they for, how do you use them?

Figured it out! Somehow, eating a hamburger made it work
