Extracting part of a global variable

Wokka — Wed, 14 Apr 2010 05:03:35 GMT

Hi guys,
Hopefully a simple request..?
I've created a simple label to extract a walls composite name. The problem is the name is too long to be practical on a floor plan ie:

'WT06 - Reverse Brick Veneer.'

I'd like the label to just note the first 4 letters. "WT06"
I vaguely recall seeing the ability in GDL a long time ago....

Is there a way I can specify just these few letters instead of the whole name?

Cheers

STRSUB is the command you are after.
For the first 4 characters of your name you want STRSUB(composite name, 1,4)

Barry,
Fantastic, thanks for that. I knew it was somewhere.
The problem is, as I've 'hacked' the original ARchiCad object, I don't fully understand all the manipulations required to get the final result.
I placed in the masterscript:

If gs_content_type = `Composite` then
identify = WALL_COMPS_NAME
endif

after adding a new parameter to the parameter list.
Where do I insert your bit of script?
Thanks again...I know time is money...

DON"T PANIC thanks but I got it to work! Cheers again!

In your 2D script there will be a TEXT2 command to add the text for the name.

i.e. TEXT2 0,0, identify

You will wnt to change this to TEXT2 0,0, STRSUB(identify,1,4)

I am assuming you are using the variable "identify" to hold the name of the composite.
But watch out because it looks like when your "gs_content_type" parameter is not `Composite` then you will have a blank "identify" parameter and no text will appear.
I can't say for sure without seeing all of the script.
