Dynamic Block to Calculate & Display Length based on Stretch Distance

[Anonymous]

Hi!

I'm pretty new to dynamic blocks and I haven't succeeded in creating one that uses any sort of formula yet. What I have been working on right now is trying to create a dynamic block that I can centre on a given object, stretch one side of the distance parameter to the face of another object, and calculate and display the calculated value of 1/2 this distance on each edge of the central object plus the width of the central object. I've tried to illustrate this below:

Thanks so much for your help!

Add FIELD inside dimension with length of stretched object.
