So what if I want to apply a filled region pattern to a selection of picked multiple rooms using this graph: ?
After running this graph it works as I thought, however, if I try to run it on another selection group of rooms, it removes the previous hatches and then applies the new process to my new selection. I see a Node from The RHYTHM package called Pick Model Elements…but cannot seem seem to get it to work…
Hi @Dave_Vaughn
You need to use Dynamo Player for this. I had a similar problem and i run through dynamo player script and it works. Remember you need to keep pick model elements in your graph to run in Dynamo Player. Good Luck!
Ok…but if I have the user run it in the player…they have no control over the filled region that they want to apply to the rooms! How can I get that wired up so that they can pick it from a list or type it into a string?
@Dave_Vaughn Do you have different filled region for each room?
I got it!
I used a new node from Rhythm (Rhythm.TextBoxInput) <<<GREAT NODE!..see graph pic.:
Yes the user has to assign specific filled regions to multiple rooms in different areas. 
“Don’t ask…it’s an unreasonable client!”
Excuse the dumb question but wasn’t this possible with revit color schemes?
Yep, It could have been done also via setting up a color scheme and the critiera…but, this is a fast solution if you don’t want to wire all that up. Run the graph, pick the boxes and hatch and done!
