I made a simple Dynamo graph to find a way of using Dynamo to insert a 2d lines Generic Family (X-Z plane) with the ability to control the X and Y dimension on each family (a rectangle). I use the Element.Parameters node to list the parameter of the selected family but I don’t see the dimension parameters X and Y in the list. Is it not the right node to use? Any other nodes I can use to control the dimensions of the rectangles?
