Extra Window/Door properties

[Ruben V]

A simple geometric measurement that is often needed (at least in Belgium where I work), is the total length of a door or window sill. This can be easily scripted using GDL (I tested this in the default window & door objects):

!Total Sill Length
IF gs_sill_outside = 1 THEN
	PARAMETERS TotalSillLength = A + gs_sill_ovhg_left + gs_sill_ovhg_right
ELSE
	PARAMETERS TotalSillLength = 0
ENDIF

A similar whish is the total inside/outside circumference of a door/window. Here the property is 2*(width+height) when the window is located at a certain vertical offset from the finished floor, and (2*width+height) when it is a door or window which is set "flush" with the floor finish...

Now we use workarounds with schedules (one column with left overhang, one with the right, one with the width) and do final calculations in a spreadsheet app. Cannot be solved with Expressions (library part parameters like "gs_sill_ovhg_left" not accessible) and adding the code-snippet above is quite maintenance-heavy...

As @Jeroen pointed out to me, this wish would also (more or less) solve my issue. But I still believe that integrating this in the standard objects would be a great addition. There are some exceptions/difficulties though, like windows with "sidelights" or combinations of doors/windows...
