tangent constrain on multiple curves

[safiredesignengineers]

hi group

is it possible to have a tangent constrain on multiple curves?

see enclosed rough sketch, i would like the curved free end or the arm to be in constant contaced with the wavey top line on the other part, the wavey line is constructed as 3 curves but i can only get the tangent constrain to apply to one of the curves.

i would like the tangent constraignt to move between the curves so the part stays in constant contact with the wavey line. this is just a mess about sketch i suppose a real world instance will be a wheel following a shaped cam plate.

regards adrian

ok sussed it!

"Transitional constraints" 8-)

If you were working from Sketch Blocks before moving to assembly of parts where you would use the Transitional, if you can replace the curves with a Control Point Spline you can then add Tangent (this does not work with an Interpolation Spline).
