Invalid Trajectory in an extruded sweep

[lindejos]

Hi Anyone,


I am trying to build a sweep in WF3 along a trajectory comprised of three curves. The first curve (sketched) lies in the TOP plane and along the horizontal. The second curve (also sketched) lies at an angle of 135 degres from the first and is contained in a plane parallel to but offset 5 mm from the TOP plane. The third curve (a two point datum curve) is drawn between the close ends of the first two curves and tangent to both (forming a smooth curve as seen in theimage in the attached archive). For some reasonI am getting an error that the specified trajectory is not valid. I've done this kind of thing before (not usually changing elevation in a curve) with no problem. Is this just a limitation of the software?


I have attached the prt file as well.

It is possible (see screen shot below). My suggestions:


-Use variable section sweep (never insert->sweep)
-Use a one-by-one selection technique to pick the curves, you do not want to get 3 separate trajectories, just 1 long one. (pick on one segment, hold shift and select the same segment again to enter one-by-one, hold shift to add the other 2 to that chain)
-sketch your section and theres your sweep

Hello "lindejos" to be able and make a succefull VSS, use
the VSS tool and select with the left mouse buttom the
first curve for the trajectory, then press SHIFT key and
select the rest of the curves.

"Lindejos" if you want to remove a curve from your
selection, just select it again, also there most be only
one trajectory called ORIGEN to make the VSS.

enjoy.
