Revit MEP: Wire Length Calculations

Tuesday, January 1st, 2013

(Part of our ongoing series comparing features in Revit MEP and Design Master to make it clear why our software is better.)

Both Design Master Electrical and Revit MEP calculate feeder and branch circuit wire lengths in order to calculate voltage drop. In Design Master Electrical, we also use this for fault current calculations, though mentioning Revit MEP can’t do that isn’t the purpose of this post.

Rather, we wanted to mention the difference in how we calculate the wire lengths.

In Revit MEP, the wire length is the sum of the distances along the X, Y, and Z axes. That’s great when you are calculating a length inside a building, but what about underground wires? There’s no option to calculate straight-line distances.

In Design Master Electrical, we give you the choice for how to calculate the wire length. You can calculate it based upon the distances along the X, Y, and Z axes, but you can also calculate it based upon the straight-line distance. The calculation method can be specified for each circuit, allowing you to control how your calculations are performed.

    Our company has been using Revit MEP for electrical design projects since 2010 but we discovered very quickly (within a few days of first installation) that voltage drop calculation is the achilles’ heal in that design package. It is completely unreliable. This is one of the reasons that our design group uses Design Master, primarily. We still have our AutoDesk subscription and regularly test Revit’s capabilities in this area (amongst others) but it has not changed in 3 years. We have found DM to be very solid in this regard and our level of comfort with it as a design package is definitely increasing with every project.

    I agree! Designmaster is better than Revit. Designmaster created by engineers for engineers! Revit created by ??? for engineers?

    Also, the example of the angles wall on the Revit website is not how an electrician would run the conduit. They would run it parallel to the angled wall!
