Edit Dimensions for Multiple Objects

[cburgessYUD2V]

Hi All, 

I'm fairly new to Revit, and I hope someone can help. Hopefully I can adequately describe what I'm trying to do.

I have an electrical conduit model from my trade modeler, and I am trying to divide the model into three sections, which match the divisions of the building, and get quantity takeoffs for each section. 

My clumsy solution to get quantities is to just delete all the conduit from the other sections and then run a quantity takeoff on what's left. But many of the conduits are modeled with long dimensions that run past the border of the section, so if I ran a takeoff for area A, it would also be counting several hundreds of feet of area B as well. For it to be close to accurate, I thought I could change the lengths of a lot of conduits so that they stop at the boundary of the section. So far I've only been able to do it one-at-a-time, which is impractical.

Is there a way to either do a mass length change, or simply chop the model off at the boundary in such a way that the takeoff will not include it? (In the attached image, the vertical line is my desired section border location.)

Any direction is appreciated!

You could use the split tool to split the conduits at each area boundary.

Then select everything inside an area and populate a parameter field with some text to identify the area - you could use one of the built in parameters such as comments or description etc or you could add your own shared parameter.

Then you can create schedules filtered via the text inserted in that parameter.

I do this all the time for bills of quantities.

What version of Revit are you running? depending on the version there may be different options you can filter by.

other than that, id do what @iainsavage suggests.
