I am trying to create a dynamic door block with standard structural opening & leaf sizes, with attributes attached to the block (dimensions, fire rating etc). Some of the attributes are variables, and some are fixed. I initially set up the dynamic block with various visibility states, but this means all the attributes have to have different tag names. Ultimately, I want to extract the attributes to a schedule, so would like to retain the same tag names. Any suggestions as to how to achieve this? I have attached my work in progress which may explain the situation better. Many thanks.
