Void sweep detaching from solid when solid moves under constraints

I have noticed a recurring issue when creating certain families (furniture in this instance), where in that if I create a solid extrusion, constrained to reference planes, and give an edge/edges of that extrusion a void sweep to chamfer the edge, the void sweep sometimes 'unsticks' from the solid geometry when it is moved.

 

See attached file. The Main leg frame of this family is constrained to a 'Width' parameter, adjusting the distance between the legs - this works fine. The edges of the legs have void sweeps around them, to chamfer the edges for a more detailed look. 

 

When I flex the 'width' parameter, the leg frame adjusts as expected, but the void sweep attached to the edge of the leg frame stay static and removes itself from the leg frame.

 

Any ideas what I'm doing wrong please?

Did you miss attaching the file?

No attached file. The family itself would be very helpful.

 

It seems that the void itself needs to be constrained to the reference planes that are controlled by the width parameter. Checking up on that may be worthwhile.

Apologies, yes I did. Please see file attached to this reply

I attached the family. I just used two legs to demonstrate a way to do this.

 

Continue working on the family i gave you. I don't have time to finish, I have to go home.... Maybe I will finish when I get there....

 

The thing is, you need to unjoin all geometry before you cut geometry. Join geometry only when you see that everything works. For sweeps, you must use "Pick Path" instead of "Sketch Path".

No problem, thanks for the work so far. Would it have made a difference that I joined the geometry? I did create the void sweeps on the leg before joining the leg to the crossrail, but maybe the void cant find the edges on the leg to cut now that it has been joined to another piece of geometry?

 

Thanks,

Yes. The "Join Geometry Tool" was definitively the cause of this problem. Instead of using "Join Geometry Tool", I created new void sweeps to cut pieces where two elements should be joined. I Attached the file. Everything works now.

Was definitely the fact that I have created a void sweep, then joined geometry. I will know for the future now, thanks for your help.
