REQUEST{2} Building_Material_info to override Parameter

Arnaut_2604 — Fri, 23 Sep 2022 08:18:10 GMT

Hi there.
I want to include the option to override Surface, Fill and Pens based on the Building material.

As I realised after my request returning 0 and checking the reference guide under Request Parameter Script Compatibility I can't use "Building_Material_info" to override a parameter after AC20.

Is there a way around this?

And out of curiosity, why was this incompatibility introduced in the first place?

n = REQUEST{2} ("Building_Material_info", gs_trim_out_bm, "gs_bmat_surface", Surf) text2 0,0,Surf Parameters gs_trim_out_mat = Surf

I included the text2 function to check whether it returns the right value which it does.

This option was discontinued because it could lead to invalid states in Teamwork.

May I ask what the use case even is?

I'm thought of using it for the trim material options on a sliding door.
Thought it would be conveniant to just have surface, fill and pens change depending on the building material but still have the option to override it, hence wanting to change a parameter.

So actually it is not really needed to give it back to the parameter.

You can use the request in the UI script, and you can show the info there. Goal achieved!

I guess, but it's not quite the override I had in mind.
It makes sense why the GS windows and doors can't be set to a building material but fills and pens need to be set seperately.
