I'm attempting to build a wing using a parallel blend. Here's the steps
I go through to create my part:
(Pro/E 2001)
1. Create datum points from external file (airfoil)
2. Create datum curve through points
3. Start parallel blend
4. Place entity on datum curve
5. For other wingtip (other end of blend), place entity on same datum curve
6. Scale second entity to desired size
7. Specify blend depth
8. Finish
My problem is with 6, the scaling. The width of the wing (from leading
edge to trailing edge) is 1.0. When I give a scaling factor of 0.55 for
the second entity, it performs as expected and scales to 0.55 of the
first, and then I can specify the depth and I have a tapered wing
section. When I give a scaling factor of 0.56, however, the entity
doesn't scale at all, it just seems to move. What's going on here?
If you'd like the part files (or trail files), I'll provide them to you.
Thanks in advance.
