In this they uses many calculations with GLOB_HSTORY_ELEV, GLOB_HSTORY_HEIGHT. F.e. UKRD = GLOB_HSTORY_ELEV + ROOM_HEIGHT PARAMETERS UKRD = UKRD LOCK “UKRD” Since AC18 it works fine for them, but with 20 it didn’t work. They use the result for the UI and for schedules. What could be a workaround? They also ask why these values are not supported in Parameter Script? Graphisoft Berlin GmbH February 14, 2018 at 10:09 #3810 Gergely FehérKeymaster GLOB_HSTORY_ELEV is a project dependent global variable, so it is not allowed to use it in parameter script. In gdl elements there is no workaround for it.
