    Rebar shape parameters

    Hi everyone,

    I'm having trouble creating an extra parameter in a rebar shape family.
    I can only add parameters a to g but I need to ad just one more variable (h).
    Can anyone tell me how to do that ?
    Or is the rebar shape limited from a to g ?

    Hey

    I do not want to add new thread so I reply to this one.

    I have rebar family as you can see on picures. I wanted to add parameter "X" which correspond to spacing between short ends. Everything goes well, changes implemented, but.... on drawing this dimension is clearly shown as 432 mm, but parameter X equals 490,5, WHY? I have totally no idea, why... Parameter X is shared parameter and described as "reinforcement length".

    Hi,

    I think this case should be sent to Autodesk.

    Rebar does not "flex" in the family like other Revit families. This allows for overlapping segments. To see how the bar behaves load it into the project and flex it is a large space. I typically place one in a floor and vary the properties to see how the bar behaves.

    It seems that when you "overconstrain" a rebar sketch, the dimensions become unpredictable. If you remove H, K parameters, X will show the correct value.

    I think you will find the numbers report correctly in the project, but if this approach works for you then great!
