I'm working on modifying some commands in our configuration, and had a couple questions.
I've looked online to better understand what the "$" does within these files. For example:
I understand that the command line is referencing a previously established variable (MS_CONFIG_DRIVE) but I don't understand what the $ is doing. Is it telling microstation to look for a previously established variable, named after the $ and between the two parenthesis?
I'm also looking to understand the difference between the ":" and "=" within the config documents.
as well as:
MS_DESIGNMODELSEEDNAME = 2D Design
On the surface, it seems like both operators work in a simlar fashion.
More specifically, I was attempting to set up an if / then statement to reference local files if the network drive was unavailable:
MS_CONFIG_DRIVE = C:/Program Files (x86)/Bentley/MicroStation V8i (SELECTseries)/
%if exists (Y:/)
MS_CONFIG_DRIVE = Y:/
But first I had tried:
MS_CONFIG_DRIVE: C:/Program Files (x86)/Bentley/MicroStation V8i (SELECTseries)/
Then first example worked correctly, but the second one did not. I would appreciate any advice. Our company no longer employees the CAD guru who set up our files, and I am working to better understand how this all fits together.
Adding to what everyone else has also mentioned I would use a different variable name than MS_CONFIG_DRIVE
This is a custom variable that you have defined, not one that MicroStation recognizes natively. To avoid confusion as to which variables are native MicroStation variables and which variables are your custom variables do not use the MS nor USTN prefix for your variable names.
Excellent point Rod!
