Schedule rebar length

[Anonymous]

Hi! Could someone tell me if (and how) it is possible to have the total rebar length in the schedule, but not the real length, I want the sum of the parts (a, b, c...). I already tried to resolve this with a formula, but it does not work for all rebars because they don't have the same amount of parts (some a,b others a,b,c,d...)??

Thanx!

Thx Rafal to take a look at my problem, but this is not really the answer to my question, as you can see on my example:

The result I would like to have hier is the sum of 550+1090+770= 2410mm, instead of the real length 2300mm...

I have the same question.

Hi @rafael_cabral 

You can add a shared parameter to the rebar shape family and create a formula for it to compute the theoretical length.

You can specify the formula for each rebar shape depending on the geometry.

Here's an example for shape 23 in the UK Revit library

@ovidiu_paunescu: It would be brilliant to have a simplified alternate formula for such cases. Just the summation of displayed values (A,B,C, etc) is enough for fast checking on site and for BoQ purposes. Maybe creating a global rebar option (checkbox) to use such simplified formulas would make Revit faster and safer for design-intent purposes.

I often get complaints from quantity surveyors and on-site engineers about "discrepancies" between segment (A,B,C) lengths and total lenght of rebar (total lenght being a lot shorter than the sum of the segments).
