Is there a nice way to do this? I'm thinking I'll either just eyeball it, or maybe pattern a few parts at intermediate positions.
What I've done already in similar situations/designs is opened a new assembly and positioned my components to the furthermost extreme and then insert a 3D sketch and convert the outer edges as a sketch. Once you have that established then either fine tune the 3D sketch or add another sketch to overlap that one on 2D..
What I've ended up doing is (in my moving assembly) temporarily mating (position only) and then adding a sketch point in my part.
I couldn't / didn't want to add external relations so just fixed them in place. I did this twice, then I made my cut and tried to check with physical dynamics, but that didn't work.. don't know why.
I ended up just checking visually by applying a section on the face of the plate, but that was a pain as it didn't update when I moved the bolt.
Anyway I'm going to add a reasonable tolerance so I'm sure it will be fine, but I'll make sure there's a good round file in the site toolbox
I'm not entirely sure what you mean, would you mind elaborating. I have just had to get it done this time, but I'd much rather find a better solution
One option is to temporarily create a circular pattern of that hinge bolt in the direction that it swings. Make the number of instances like 20 or so (or more). and make sure that you are only doing the pattern instance like 30 degrees or so (and not the full circle).
So then basically, you will have a bunch of bolts all in one little area with one little step.
Then edit the part you want to add the clearance hole to and make sure that none of your sketch lines come in contact with any of the patterned instances.
oooh that gives me an idea Dan - I could offset the intersecting bolt surfaces in my part and pattern a few of those and get some intersection curves. What worries me is, both the hinge and bolt position and the door thickness could still change before this design is ready
Then create a 3D sketch at the assembly level with arcs that have their center at the pivot point of the bolt swing and have them tangent to the extreme edges of the bolt. Or better yet, sweep a tube around the bolt using those arcs.
Then use those to drive the position of sketches in your interfering part.
Later, once you have finalized the design, you can remove the links and the arcs and sweeps (if you want to) and just leave the hole.
This worked out pretty good. In the part in my defining assembly I copied the relevant faces from the bolt and also created an axis from the hinge pin.
I didn't use a pattern, I cut the faces in half along the bolts front plane and added split line along it's top plane, knitted a planar face to locate the part on the axis, repeatedly used move body with mates / intersection curve
I think I did a few unnecessary steps, but I'm hoping this is parametric.
Thanks again Dan and John
One thing that I notice.....
That area with the red square.....if something is mounting to that bolt, then will you have issues with that something interfering with the same plate?
Here's a pic showing the arrangement a bit better Dan. The door will stop against the opposite rebate.

I would definitely setup temp files that cover the different door thickness and movement and since your the Master Wizard - surely there are some mathematical calculations that are just ready to burst open your brain, door thickness A = (1-1) Hinge Swing Radians - door thickness B = (1-2) Hinge Swing Radians...
Basically what I had mentioned falls in line what Dan Pihlaja mentions, where both would get the worse case scenario on the swing, Dan mentions a pattern, I mentioned just inserting two, one on each end of the outer extremes..
