    Default Supply diffuser dynamic block - stretching

    Hello, AUGI members.
    I need your help with a block.
    I am trying to make a block (dynamic) that will do the following:
    1. Rotate incrementally @ 45 degrees.
    2. Flex duct (zig zag pattern) be able to "stretch"/"shrink" (not like an accordion, but more subtracting or adding the zig zag pattern)
    I currently have 5 visibility states showing each state when stretched.
    I know it would have something to do with Lookups, but I am not well versed in the matter.

    Thanks in advanced.
    -Adam

    I played around with this during lunch.

    I handled the zigzag pattern as arraypath set to a construction line between the line in the center and the end line.
    I stretched and rotated the end line and the construction line with a polar parameter and polar stretch action. (angle increment set to 45 degrees)
    The partial circle and center line are a rotation parameter & action chained to the polar stretch.

    It works ok. I wish it were a little cleaner such that the zigzag pattern never overlapped or gapped the line in the center.

    Hope it helps.

    Attached block is a little better. I modified the array of the zigzag pattern so the zig and zag array separately. A little less clunky and less overlap of the center line.

    Having an issue with this block - it seems to insert fine in a new drawing, but when I insert into an existing file, I'm getting the attached error.

    I'm completely lost - any advice appreciated.

    Hmm, I've never come across that message before.

    Check the ARRAYASSOCIATIVITY system variable in each of the drawings. Mine is set to 1.
