Hi Pierre,
I see your point, sorry.
Actually i do not see a reason for not having the possibility to use a shortest path ligament, we have all the ingredients to create this facility, i have added this element to our wishlist.
I do not have the equations on hand for this, i will try to see if i can get hold on them.
In the meanwhile there is a hack, but it is by no means elegant but i think it would work…
[ol]
[li]Create a dummy segment
[/li][li]Create a prismatic joint on the segment
[/li][li]Create the AnyKinSPLine
[/li][li]Create a AnyLinCombinationMeasure between prismatic joint and AnyKinSPLine use Coef={1,-1} meaning that measures will be equal
[/li][li] Drive the combination measure to zero, have the reactions switched on…
[/li][li]Create the AnyViaPointLigamant between dummy seg and ground
[/li][/ol]
Check the force is acting as intended!
Best regards
Søren
