Hi,

As described in this article: https://knowledge.autodesk.com/support/revit-products/troubleshooting/caas/sfdcarticles/sfdcarticles/Difference-in-measurement-between-length-and-cut-length-of-a-beam.html

"Length is the measurement of the beam's representation in Coarse detail display. Cut Length is the measurement of the physical geometry in Medium and Fine display."

Kind regards

Dear Mr.Jeroen

thanks for replying, but not understood its concept behind cut length and length, what is the use of it

regards

which length represents for material take-off consideration as the length
of the concete beam

Hi,

As stated in that article, the lenght is a representation, the cut lenght is the physical geometry (the 'real' lenght). So the Cut Lenght is the one you need.

"Length is the measurement of the beam's representation in Coarse detail display. Cut Length is the measurement of the physical geometry in Medium and Fine display."

Kind regards

the length is the distance from start and end points of the framing element

cut length is the clear distance between the supports of the framing element

cut length is always less than the length of the framing element

Cut length is the actual length of the framing member, but if I build a parametric family (ie angle wall) from L-angle framing members and share them in the family then place in a project, Revit only reports the framing member length in a schedule not the cut length which is basically useless.

Any ideas how to get the cut length to report?

That is very helpful thank you very much sir

The only reason I am responding is to correct this as it was marked as the solution and is wrong.

As noted in the other solution, the length is the one line representation of the element, center to center.

The cut length is the actual physical length and can be longer than the length. Example: a beam resting on top of two columns will have a cut length longer than the length.

This is WRONG. Cut length can be longer than length. It all depends on the cut angle. If you cut an RHS / SHS at 45 degree then definitely the cut length will be longer than length

Put it simple

Length is the distance between end points in 2D, think about structural analysis where you only model a beam element as line element.

Cut lengh is the actual length you need to buy to make that member (i,e distant between perpendicular lines of 2 furthest ends). So for the fabricator, they are only interested in cut length because that is the length they need to purchase from mill.

Below is an example of cut length > length

Isn't that what I said in the post right above yours?
