hi anyone know if it is possible to create a family using existing family members and not extrusions? what i need to do is create a family consisting of a single vertical plane unistrut frame that is copied along a bay of columns. however since the size of the unistrut can change i would rather be able to open the family and change the strut from a drop down menu from the unistrut family, then save the parent family and all change within that bay. hope thats clear! like in CAD where you create a block then you just have to change it once when there's multiple instances. i know this is similar to families but in cad you could make a block out of multiple blocks cant seem to do that in revit any help appreciated!

Has anyone developed a way on Revit MEP 2013 to automatically select a pump from a loaded family based on a specific flow rate calculated? As opposed to manually selecting the pump size yourself? It would be much appreciated if anyone can shine any light on this subject! Alex

I am modifying a pre-existing electrical panel family and the goal is to create text on the panel in elevation view to reflect the panel name. The issue I have seems to be that even though I type a default panel name in the "Panel Name" parameter (I used "zzz" so the value would stand out), when I load this family into a project and attempt to place my first panel, it comes in with a blank value in the "Panel Name" parameter slot. Typically, this would come in with a value of: "zzz". Again, this is an "out of the box" family that I am attempting to modify, so I am partly wondering if this is because a something has been done to force this field come into a project empty. Any ideas / thoughts are much appreciated. I will also say, that once the panel is inserted, you can give it a name, then update the family to include the functionality and everything works great (because it has a name now). The problem is, getting it to come in with a default name, so you can change it after placing it into the project. (I am using Revit MEP 2011) Thanks,
