@jorge, looking at your model, I think I got a good result from it. Please download my model and look at it. I flipped the component up, and then moved the line to be directly under it. Shape bender will offset the final shape from the bending shape by the same distance that the component is offset from the straight line. So since you want to bend exactly to the shape of the bent shape, then the component needs to be directly on top of the straight line.

I can make a video that explains it better if the model came out right.

Hope it helped,

Chris

Thank you, Dave and Chris.

It works when the curve is parallel to the green-red plane (see snapshot).

But, why the curve on the left (parallel to the blue-red plane) did work?

The second and third pictures might give you a clue:
if the curve has angles > 90 degrees it bends ok.
Ignores if angles = 90 deg.
And changes directions if < 90.

My problem is solved. I will flip up the entire model (as it should have always been). Thanks again.

I can't tell from your screen shot but I wonder if you have the "curve" laying down on the ground plane or is it standing up. If it is standing up vertical to the ground plane, that would explain why it isn't working for you.

The curve is in the blue-red plane. It works with the curve on the left, but not with the profile curve on the right.

Here is a new picture and the model.

Thank you both,
Jorge.

Thank you for this useful script.

1. How can I solve this error: Error: #<TypeError: Cannot set the length of a zero length vector)>

Probably it is related to the curved line I am using.
Some parts of my model <bend> in each direction, as in the picture.
No group is created after pressing Enter.
(I have no component spray script installed).

2. If someday there is a pro (paid) version of this scrip, here are some ideas:

• be able to UNbend a profile.
• be able to calculate the bend gains (as explained in next link)
