Label Object in "Find and Select"

Jochen Suehlo — Tue, 14 Sep 2021 07:12:51 GMT

I have created a label object, which reads the Building Material from a wall.
The pen color of the BM is used to place fills besides the wall.
The label thus graphically identifies the building materials of the wall surfaces.
Now I want to activate only the labels (not the walls) with "Find and Select" which have a specific BM color. Unfortunately, this is not provided for in "Find and Select".
When I try to overwrite some of the labels pen colors like AC_LabelPointerPen with a free value, this does work, but I cannot use the REQUEST{2} ("Building_Material_info"...) in the Parameters Script to do this with the BM color.
Any ideas if I can use "Find and Select" for this purpose?

I'm not sure you can. Objects, that are created in GDL have two type of variables - common (independent from GDL script and shown in element settings - that might be pen colour, font, fill type, element elevation and sizes) and variables that set in GDL script. In your case pen colour is set in GDL script and invisible for Find and Select command. When you press "Add" in "Find and Select" - program is showing which variables you can choose - and there is no access to variables set inside of GDL element.

Hi Joachim,

The closest I can think of is find&select the walls and put them to another layer. Hide other layers except the wall's and the label's. Labels which annotate hidden layers are also hidden, so you will only see the labels of the selected walls.
