calculate total length lines

[arj]

If multiple lines are selected, Revit should automatically calculate the combined total length and display the result in the Properties palette.

[Scott_D_]

The answer is either:

A - Use a length based family that presents as a line with a Shared Parameter so that you can schedule their lengths and sum the length values

B - Don't use Lines

There's a "Calculate total length of selected lines" dynamo script included with Revit installation.
