hi
in the attached file I have a line and a tube thingy
I'm creating a point group on the line and on the tube
in DOPs I'm setting up an sbdconstraint and feeding that into an applyrelationship DOP

if there is only one (1) point in the line group (goal points) then it works exactly as I'd like, but if there are more than one - all the constraints jump to the first one they find…

not sure what I have wrong but I'd be grateful if someone would take a look.

I think at one point I was trying to do something similar. Hope this example helps!

ah…very nice…
I think the trick here is to use the RBD Point Object…

thanks VERY much!
