I want to create a path mate, to constraint the center of the sphere to remain on the composite curve1.
Impossible to constraint the sphere, otherelse than to remain on one of the arcs, but nope on the whole comp. curve.
Tx a lot for any help
It looks as though the spere is constrained to the curve but as you say it moves around on the curve freely. If you want to constrain it to one position on the curve then I would think you could add a plane to the specific place you want it constrained and use one of the planes in the sphere to mate it.
I used Plane 2 on the curve in the attached JPG.
No, my problem is with the sphere, which isn't constrained to the curve.
The sphere is constrained only to a part of the curve : the large arc, but isn't constrained to the lower part of the curve.
I re-draw another composite curve, to show the problem more accurately.
Perhaps I could draw a spline, instead of 4 arcs, but it isn't consistent that the path mate don't match with a whole composite curve.
I also join a screen capture, to illustrate the problemo : the shpere is constrained to the large circle.
It seems like a Composite Curve would be the right thing to use for your mate, but I don't believe SW actually works that way. Using a Fit Spline is probably going to give you much better results. I think Composite Curves were originally introduced to fix some of the limitations that SW had, but somehow the fix never really worked.
Tx for your help.
Really too bad that a path mate don't work with composite curves....
Really unbelievable, to be frank, but it isn't the first unbelievable mis-working I met with this unbelievable program.
So, I will use a fit split, but it's really not consistent.
I managed to do something like this using a composite curve on one assembly I created some time ago. The trick I used is create a surface following the path of the curve and use the edge of the surface in the path mate. On the pathmate dialog box, to select all the the edges of the surface, I used the button "selection manger" and after "select group".
I hope this helps.
I made a spline, but your solution is more accurate.
Tx a lot for it, but I have to admit that SW isn't always very friendly
