Elevation From Level Parameter

RC_RVT — Wed, 02 Oct 2024 12:35:58 GMT

Can I add the "Elevation From Level" system parameter into a Revit family so I can refer off it?

I'm wanting to add another parameter that goes: if(Elevation From Level>1000mm, "Wall End Panel", "Base End Panel")

Is there something else I can do? I know that I could create another parameter that would work the same way as Elevation From Level, but I really want to use the existing parameter to reduce confusion for other people using this family.

almost all the 3d families have the Default Elevation as Elevation from Level:

for example : if(Default Elevation > 100 mm, 100 mm, 10 mm)

Thanks for the reply, but this doesn't work. As the default elevation is set as 0 which it needs to stay as. But then when I change the elevation from level in the project the Default elevation formula no longer works. See below where I try and explain it better.ABCD

🤔so you can not use that way,you need to use the another way that you say, this is interesting i never use this (Default Elevation), i always use reference plane in elevation and control the height.

I use this way because, if I use a custom parameter (e.g. Height To Floor) to control the base of an object, the reference planes go all the way to the floor level, regardless of how far off the floor the object is. Then when I add dimensions on lower units/panels, the witness line connects to the wrong reference plane (the wall units/panels) due to it being all the way to floor. Sounds like something small probably, but when you are doing this all day, it just doesn't work to keep having that happen. I'll figure something out hopefully. Thanks for your input anyway.
