Constraint question

[sps_cad_guy]

I am working on a project where I need to constrain some round pegs to a rolled bar.

I have attached a screen shot of what I have.

How would I constrain the pegs into the holes where the full round surface of the pegs was fairly flush with the inside surface of the rolled bar? The one peg I have in there, I just put in manually, so it's not locked into position at all.

I really appreciate your help and suggestions with this.

I would do a concentric mate first then to get it allingned with the hole then to a tangent mate with the backside (inside surface) of the curved plate with the end of the peg using this command.

I don't seem to be able to get the concentric mate to work.

Could it be because the hole in the rolled bar were put in while in the flat?

I haven't done any work with sheet metal, but what would happen if you rolled up the end of part marker to above the roll feature, and added a work axis to all of the holes?  You might then be able to use those for constraints after the rolled feature?

[Cadmanto]

The problem might be that because the hole is on the curve, technically it is an elipse.

Try creating an axis through that hole first, then do the concentric to that axis.

I appreciate the help, but I don't seem to be able to even put an axis in my rolled bar.

I've attached it here, so did I get off from the very start on the wrong foot?

When attempting to put an axis in the holes, it only seems to pick up the center of the rolled surface.

I am still on 2012 so I can't open your part.

Are you saying that neither one of these axis commands are working for you?

I tried my idea (above), if you roll the end of part marker to above the fold, you can add work axes to these holes.  You SHOULD then be able to use them for constraints.

CORRECTION... when rolling the EOP marker back down... the axes do NOT stay with the holes.  😞 

Try Scott's idea!  LOL

One way:

Constrain to the work axis.

Thank you very much to all for the help.

This was what I was able to make work for me.

Then, after using cooincident mate to the work axis and

center of the peg, I was able to make the flat end tangent

to the inside of the rolled bar.

Thanks again for the help.

I don't work in assemblies very often, so it's a learning

challenge every time I do.
