MicroStation/Inroads Manual

Our MaineDOT MicroStation/InRoads Manual is available either as a single (large) PDF file, or as individual (much smaller) chapter PDF files.  We completed our first revision to this manual in early October, 2008, which updates everything to MicroStation V8 (2004 Edition), current InRoads documentation for both Design and Survey, our current standards, including US Customary Units (feet and inches).  This manual is intended for projects that are designed in InRoads. Some of the chapters in this manual are the same as in the MicroStation for MX manual.
