I created a Dynamic Component of a basic straight conveyor(attached) that allows me to enter some specific parameters. So far the Dynamic Component is working really well.

What I would like to create next is another Dynamic Component of a 90-degree conveyor(static example attached) that allows me to enter the same parameters as the straight conveyor plus specify an Interior Radius.

I can’t seem to come up with a good plan for the attribute settings to make the 90-degree conveyor work. I’m not asking for someone to do the work for me, but to point me in the right direction. I did find a post where the idea was to break the arc down into an individual arc segment, then rotate and copy that segment about its center point:

Change curved section by dynamic components

Hi there, please excuse my bad english. I am native german speaker. Ok, I can move objects by dynamic components. But I need to create an individual radius for to produce a press braked steel section. For instance: For to draw an simple L-section L100/100x3mm there are 3 elements. 2 flat sections 94x3mm and one radius section bedween both flat sections. Inner radius 3mm + 3mm thickness = 6mm. Now I would like to rotate one flat section by different angle. That is easy. But how could I change the…

Trying to figure out a simpler way if possible. Any guidance is much appreciated.

first the rollers or any object can be position using polar coordinates and rotated
