I am using Advance Steel 2021 along with the Graitec Power Pack. I'm trying to use the Graitec two-flight stair macro to speed up our work flow but when I get to the landing length, I cannot set the inside stringers to our desired length of four inches or turn them off as you can in the original Advance Steel Stair Macro. Using the original one-flight I would extend and than cut the inside stair stringers 4 inches to the platform. How do I get this four inch conversion from both flights tread noses to the platform when using the Graitec Two-Flight Stair Macro?
