GDL: Label_Marker_Form & bmat_ID

Hi all,

https://community.graphisoft.com/t5/GDL/Hack-the-Surface-Label/m-p/621379

Following on from this thread about splitting Surface names, I got it working with Composite and CP names, but have run into an issue with Building Materials when it comes to beams and columns... For all situations I have it working, I just replaced the _sContentStringsHead[1][5] parameter with the value that I wanted displayed to then be passed on into the label_marker_form stock macro to be displayed. For what ever reason though, the value that I am inserting is getting placed between a pair of numbers followed by a bmat_ID from the element. For beams, this is the number Zero. For columns it is Zero/One for the core, else One. The extra bmat_ID for columns seems to always be the core. If I do not insert anything in the the _sContentStringsHead[1][5] parameter these numbers bound a "x" usually. The veneer bmat shows if there is one though...

_sContentStringsHead[1][5] = bmat_ID

_sContentStringsHead[1][5] = bmat_id

Default _sContentStringsHead[1][5] value

Default _sContentStringsHead[1][5]
