Hi, I doubt that it will be functionnal after a downgrade of the version. Please let me know if it works or not.
Meanwhile, I will be working on a block that would include only dynamic actions and parameters. Note that this could take a few days!
Yep, won't work in 2007. When opened it lost all dynamic properties.
Arg. My boss won't upgrade to 2013. Gotta make due.
Alternatively, maybe having a thicker line on the end of the arc would work.
Or making the arc a pline and then having thicker ends.
Preferred is the arrow but with the limitations of 2007 we might need to adjust.
After a few tests, I think I could get the block to work. There are some limits to what can be achieved with dynamic action and parameters, so you might not be able to use it in all situations.
Please have a look at the file and mark as solved if this is the solution to your problem.
