need help with TRAJPAR

[gggggggggg]

I'm trying to create a variable section sweep & use the trajpar relation.



How do I write the relation so that the dimension of the sketch is 1.5 at the origin (in the sketch) & .75 at the end?

If you want a linear transition:



d = 1.5 - .75 * trajpar

 

[gggggggggg]

thanks noppenbd.
