The measure toolset is very weak compared to something like Sketchup, with its inferences and ability to measure along axes, perpendiculars, parallels, etc. I would expect the measure tools in NavisWorks to be much more robust since it is intended to be used downstream of design by Contractors, Subcontractors, and Facilities Managers. I'm new to NW, but the instructor teaching my essentials class is of the same opinion, so I'm guessing this is something that needs to be addressed. As a builder, this lack of simple functionality is enough to make me put the CD back in the box and ask for a refund. Hopefully I'm just overlooking something. Thanks in advance for any feedback.
