Wall parameters-available for doors/windows

[Anonymous]

Hello,
Does anyone know what the globals "wall_max_height" and
"wall_min_height" refer to in wall parameters- available for
doors and windows ?
Thank you,
Peter Devlin

Curious myself so did a quick experiment.

The manual was a big load of help - wall_max_height" = max height of wall and "wall_min_height" = min height of wall - fantastic insight

These don't seem available for use with doors and windows - just get "0".
But in a property script for walls I did get some values.
If the wall is trimmed to a roof then the "wall_min_height" is the lower trim height and the "wall_max_height" is the upper trim height but beware of openings as in the attached picture.
The upper height is to the edge of the window hole and not the top of the wall as you would expect.
I'm sure this would be different if the window wasn't full height.

WALL_HEIGHT is of course the overall height of the wall.
This will be the same as WALL_MAX_HEIGHT if the trim passes through the top of the wall (and there are no openings).
But if the top of the trim passes through the side of the wall then these will give different values.

Hope this is of some help and I was clear enough in what I was trying to say.

Hello Barry,
Thank you for doing some investigation and posting back.

You say:
"These don't seem available for use with doors and windows - just get "0". "

So it's an error in the manual listing these globals as "available for
doors and windows". The manual should have put them in the
parameters available for listing and labeling.

Not the first error in the manual. I can think of several.
Thanks again,
Peter Devlin

Some more info (read it carefully, because it is tricky):
WALL_MIN_HEIGHT
When a Wall is trimmed by a Roof, this variable returns the smallest height of the Wall body resulting from the Roof Trim. Simply cutting the Wall by a Roof to its Base (as opposed to its Top – the default operation) does not affect this value. But in case the Wall is cut by a Roof to its Base, plus the Set Wall/Column Base to lowest Point checkbox is checked, the Wall’s height will be modified and this value will reflect that change. Performing SEO operations on the Wall will not affect the value returned by this variable.

WALL_MAX_HEIGHT
When a Wall is trimmed by a Roof, this variable returns the greatest height of the Wall body resulting from the Roof Trim. Simply cutting the Wall by a Roof to its Base (as opposed to its Top – the default operation) does not affect this value. But in case the Wall is cut by a Roof to its Base, plus the Set Wall/Column Base to lowest Point checkbox is checked, the Wall’s height will be modified and this value will reflect that change. Performing SEO operations on the Wall will not affect the value returned by this variable.
