Variable section sweep problem

[engmechs]

Hi all,

I am working on a variable section sweep, & origin curve depends on another curve defined in another graph (profile).

Everything seems ok as after I input the relation, the section size changed to match the initial graph y value.

However, it doesn't reflect the variation in cross section, when it goes along the datum curve. Only at start point. Do I miss something?

I wonder if I need to match the parameter value between graph feature & VSS feature to get the relationship. Or something else? Any idea?

Regards,

if i am following you right, your relation

sd4=evalgraph("graph1",trajpar*5)

whatever your graph and dim are....
the trajpar* part has to equal your graph length

do a vss on a rect. with the top adding on your graph sweep
and then change the "* length " part of the relation it will make it clearly than I can say it

Thanks cadcamguy, I will try it out.
