TxDOT Standards were created for the GEOPAK Civil Engineering Suite product layered on MicroStation. The workspace can be set up in your custom workspace directories, but one limitation you will notice is the civil specific Project Configurations from the PCF will not get loaded. In order to get the Project specific variables to load, you must edit the PCF and comment out lines which are calling up the SUITE_INSTALLDIR.
SOLUTION: In the TxDOT.pcf on line 117, it is calling a %if defined(SUITE_INSTALLDIR). Since we are setting this up for PowerGEOPAK, this line cannot exist because it is automatically loading the GEOPAK program with PowerGEOPAK. Edit the PCF and add in a comment on this line and on the %endif statement at the end of the file (line 218) to bypass this from getting loaded.
