Dynamic blocks that do not have the same x, y, z scale (absolute value) lose their ability to modify the dynamic properties.

I did some research and found dynamic blocks that do not have the same x, y, z scale (absolute value) lose their ability to modify the dynamic properties. I have a dynamic block with a stretch property that lost the ability to change its dynamic property when I scaled, mirrored, or rotated. In my case, the x, y, z scales showed up as 1.0 in the Properties palette, but for some reason they were not being recognized correctly. When I retyped 1.0 for the x, y, z scales, my dynamic properties came back, which allowed me to modify the blocks' stretch property."

NOTES FROM CADALYST TIP PATROL:
Good workaround. Sometimes when features are applied, they don't always work as they should. So users have to find ways to trick AutoCAD into doing what we want it to. This is a good tip and a good procedure: If your dynamic block doesn't work, re-enter the data, even if it is the same data.

Nick Azbell wrote in response to our October 27 issue: "When making dynamic blocks, it is good practice to check the Scale Uniformly box. That way if the block is scaled, all directions hold the same number and dynamics are retained."
