How to get length property of pipe?

Hi
I want to filter all of pipes, which has length>=500mm.
But I can’t find out the length property of pipe.

Unfortunately geometry of pipes can be modeled in many ways and they can be in many different positions, so it is difficult to come up with a generic algorithm to calculate the length. You have two options:

Use the Bounding Box Length: This works for horizontal pipes. Bounding Box Height works for vertical pipes. Note if you create a filter where you are filtering for both, then only pipes that pass both conditions are accepted.
Check if pipes in your model has property sets that provide the length for pipes and use that in the filter.

Hi, If the model is created in Revit initially then you can make sure that the parameters that control the object are exported. These parameters are contained in the dimensions properties. These can be exported by checking the Export Revit property sets or by mapping these parameters only using a mapping table associated to the export. These parameters can then be used in your rules.
