First time poster here. I am self teaching myself Dynamo in between projects at work, so I will not pretend to know anything Im talking about.
I have several instances of detail components that i would like to have dimensioned at the same “edge” geometry reference. I thought it useful to have Genius Loci added for this reason. I ultimately would like to be able to select a single instance of a detail component, select the edge reference to dimension to, and a dimension string is automatically placed. There are areas where the dimension string would run vertically as well as horizontally. For reference, see below snippet of components in question:
Hello @dlovelessZJ2SZ welcome 
yes it should be possible from family instance detail component in this case, we can get all these reference named or not as we can when dimension manuel, and yes genius loci have nodes for that, show us what you have tried so far and we can try help from there…
i figured the first order of business was to select all “like” detail components in the view. This is where i have hit my first roadblock. im trying to filter the list of ALL detail components against the single selected component from the view. i was anticipating 13 true in my list, but ive got none.
yeah, great, but instead try very simple with one detail component, just with the select element node, download genius loci, there is a node guess it called family instance get reference or something it should give youy all refrence for this component and planes as well and then use genius loci dimension by reference node for the dimension…have downloaded genius loci? try this first and if go stock just show us from there and we can probably help…btw which revit version are you in ?
here is a very basic example as could be a start with genius loci, what i try dimension is a very simple beam section detail item, as you see sometimes it can be hard to find the right refernce specially when they dont have any name, but possible…in that case it can sometimes help create a rectangle by plane in these planes so we better can see them i dynamo preview, for get the right ones
