I am trying to create a family that has a minimum line length that won't just kill the family when it gets smaller. Im using the if(a<b,b,a) statement but when I load it, it just shows in the properties its the minimum length but the line is smaller than the minimum value in the model. The other line just kills it when it becomes to small. I just want it to stop at that min. length. Help!

Hye MelDesign,


Could you add the family in question?


however, looking at the formula I think this is where you going wrong.


When I use min and max length control I use two parameters. One to contain the formula and the other for user input. See the below family.


Hope this is what you were after.
