Auto Dimensioning for Horizontal and Vertical Dimensions by Clicking in between two lines.

[Rukuto]

I would like some help to create a function that would allow me to select a point in between two horizontal and/or vertical lines and it would give me the vertical and horizontal dimensions between those lines. It's a 2D drawing but some lines are of different z value. I have tried using chatgpt to create a code but it is not able to properly select the nearest line from my specified point (after running the command). 

This function is there in the new sketchup. I was hoping to use it to create internal dimensions in an architectural plan.

In newer versions since AutoCAD 2016, the DIM command can already do this. What do you need that is not in this feature?
