    Default Dynamic Block with Dependent Drop Down Lists

    I am trying to create a dynamic block with three dependent drop downs. I've gone over one forum post (https://forums.autodesk.com/t5/dynam.../td-p/11700945) that is what I am looking for but the example that is in the post only has two dependent drop down menus and I need to figure out how to do three or more.

    I have a block "horizontal.dyn" which has several different size horizontal beams. There are metric and imperial beams. There are 4 applications which the beams can be used in. Only certain beams can be used in certain applications.

    I have tried to make this work, but I am stuck in how to get three drop down menus to work with the method used in the attached "drawing3.dwg" which was the sample in the post above. (drawing3.dwg was created by someone in the Autodesk forum shown above.)


    Example:

    You can see in the chart below that 265mm is only used with splays, 500 mm is only used in flooring etc, but 1000 mm can be used in either flooring or seating. (Obviously this is only a sample. My blocks have way more options.)

    I want three menus: Equipment Type, Measurement, and Sizes.

    Metric Sizes Imperial Sizes Flooring Seating Stairs Splays
    265 mm X
    500 mm X
    1000 mm X X
    2000 mm X
    10' X
    66" X

    I would like the menus to flow like the following:
    Equipment Type -> Measurement -> Sizes
    Flooring -> Metric -> 500 mm
    -> 1000 mm
    -> Imperial -> 10'
    Seating -> Metric -> 1000 mm
    -> 2000 mm
    Stairs -> Imperial -> 66"
    Splays -> Metric -> 265 mm

    If someone can help me figure this out, this would help me in programming my other blocks that have similar structures. I think it would greatly make the blocks much more user friendly for those in my team.

    I have attached a copy of my block and the spreadsheet I used to program it.

    Default Re: Dynamic Block with Dependent Drop Down Lists

    Reading that thread you linked provides some insight on how to handle your situation. The sample shown in the first post of that thread is using a Block Properties Table Action. It is currently misconfigured, though. Another post in that thread explains how to adjust it to work properly, which was to adjust the column order in the Block Properties Table.
    If you have a technical question, please find the appropriate forum and ask it there.
    You will get a quicker response from your fellow AUGI members than if you sent it to me via a PM or email.
