Kudos to GS for a truly magnificent part (i bet it's typical for all DH windows, but I'm too lazy to check)
W double hung MU 10,
When you change 3D Detail level in the parameters list, it actually reverses the sash locations: upper sash moves in, lower sash moves out. The mullions stay the same.
How are we ever going to really use BIM, if the I and M are totally F**K'D up?
And yes, I know, we are all just waiting for the day when the window MFR provides the lib part for free from their website. Then we'll be really cursed because they'll lock their code, and Anderson's manufacturer parameter will be "MFR" and Marvin's will be "MANUF" and they won't schedule.
I can see it's going to be great....
