Requesting Parameters from another Object

[Kyle Boyd]

I am wondering if it is possible in 19 to request/reference parameters from other objects. (I am building some custom labels).

Currently I can grab an object’s ID using GLOB_ID, or similar. But I would like to grab a specific parameter in the object say, randomPAR. Is this possible? If so, how?

So far I have tried:
I have a custom object with the parameter TestPAR defined in the Parameters as a text parameter. In my label object, I try

re_parameter = REQUEST (“ASSOCLP_PARVALUE”, “TestPAR”, nameind_TEST, type_TEST, flag_TEST, dim1_TEST, dim2_TEST, val_TEST)

labelText = val_TEST

but it results in the error “Uninitialized variable
at line 13 in the 2D script of file TEST LABEL.gsm.”

I have also tried substituting “ac_bottomlevel” for “TestPAR” with similar results. Can someone help?

*this is a duplicate to a post I made on Archicad-Talk, but I figured would post here as well.
That post is here
Also I have referenced this post from 2003 https://archicad-talk.graphisoft.com/viewtopic.php?t=648

Initialize that val_TEST variable.

val_TEST =""
re_parameter = REQUEST (“ASSOCLP_PARVALUE”, “TestPAR”, nameind_TEST, type_TEST, flag_TEST, dim1_TEST, dim2_TEST, val_TEST)

labelText = val_TEST

If you don’t initialize you will always get a warning. Sometimes it doesn’t matter, but with Requests it often does. If variables aren’t initialized, they are assumed to be numbers, and that variable needs to be a string.
