Door Unit Height Calculation

b_almquist — Wed, 24 May 2023 08:41:00 GMT

ArchiCAD seems to be miscalculating door unit heights. It's not adding the thickness of the threshold or sill into the calculation. I tried creating a new property for "Unit Height w/ Threshold" as an expression but the threshold checkbox and threshold thickness parameters aren't available as a values in an expression. Has anyone else come up with a solution to correct door unit height?

Could you copy-paste the exact Expression you created, plus screenshots of the Door in question and the result?

7'-0" (door leaf height) + 1 1/2" (frame thickness) - 1/2" (frame rebate) + 1/2" (threshold thickness) = 7'- 1 1/2" (unit height)
ArchiCAD calculates the unit height as 7'-1", ignoring the threshold thickness.

I was not able to create a property for 'Unit Height w Threshold' because the Threshold Thickness parameter (gs_treshold_thk) isn't available from the list of Parameters & Properties available in the Expression Editor.

I think on the third screenshot the 1/2" is to the top of the threshold, not the bottom of the Door Leaf, the Door Leaf is lower. So I don't think the Threshold Height is added when calculating Unit Height.
