Hi All,
I am working on a door family and need to be able to input a dimension from either the left jamb or right jamb for a reference plane that can move within the width of the door. Currently it is simple to have a parameter that moves the reference plane left or right from just one side, the part that gets tricky is adding another parameter that moves the reference plane left or right from the opposite side. I am thinking there is a formula that can force this to work but i have no idea what it might be. I have attached some screenshots of what I am working on that probably explains is a little better.Distance width.JPG
