Shape bender issues

[L i am]

Hi all, I just downloaded CFL Shape Bender and am getting unexpected results. Am using SU 17 make. Can somebody please advise what may be going wrong.

Cheers

When in the preview mode when you get the green structure, hit the down arrow key to reposition the Preview. If it's not the down arrow try the others, I can't remember specifically just now.

It'd be clearer if you posted a SKP so we could check it out.
The line is best draw along the red axis and the group you are bending behind it and the arc behind that.
Also the line/arc should be of sufficient length to give the bend needed.
As @Box says you can also flip the bend using the toggle key presses when it's previewed.
