Im trying to create ventilation duct section using dynamic block. Duct section consist on:
1) outside circle (dashed) - it stands for insulation fd the duct.
2) concentric inside circle
3) "moon" inside.
In this DB I would like to be able to manipulate:
1) diameter of the outside circle (dashed)
2) diameter of inside circle
and I would like the "moon" to be scaled while Im changing diameter of inside circle
I was trying to do thatusing constraints and using scale parameter. Both blocks you can see in attached drawing. As you can see I cannot achieve my goal. My DWG file in the attachment.
Any help will be apriciated.
