Global Modification

[Lingwisyer]

Hi all,

Is there someway to write back to Globals?

Not with GDL that I know of.
What GLOBAL are you trying to alter?

I am sure you could control them with an add-on or of course they are just standard Archicad settings which you can change.

WIDO_SILL is apparently a global parameter instead of a standard parameter like A / B / ZZYZX.

I found a modifiable version of it in ac_wido_sill which writes back to WIDO_SILL. Though this is from wall face rather than core...

Hi Lingwisyer,

no, globals are one-way communication from Archicad to GDL. Technically it's allowed to change them, so your code and called macros see the changed value, but AC doesn't read it back.

Any reason WIDO_SILL is a Global rather than a standard parameter? Or is there some other parameter that I am missing that is Reveal to Wall Core?

Historic reasons and keeping backwards compatibility.
You can use ac_wido_sill. The distance from wall face to core can be calculated using WALL_SKINS_PARAMS.
