Let me elaborate. I'm working to create a Revit family for a running track for work. The tricky part is I'm trying to make it as customizable as possible so that I can just change parameters when I load it into a project, and this includes the number of tracks, whether I need 6 tracks or 8. I'm wondering if it's possible to make a parameter that can automatically create the number of tracks I need in the project without copying the extrusion and just adjusting it to fit the previous track. I've tried playing with visibility graphics, array and offset tricks but nothing seems to work. Any tips would be immensely helpful.&nbsp;</P> Mon, 13 Oct 2025 18:47:30 GMT https://forums.autodesk.com/t5/revit-architecture-forum/is-it-possible-to-create-a-revit-family-that-automatically/m-p/13850138#M362014 pfarsonAA4ZQ 2025-10-13T18:47:30Z https://forums.autodesk.com/t5/revit-architecture-forum/is-it-possible-to-create-a-revit-family-that-automatically/m-p/13850174#M362015 <P><a href="https://forums.autodesk.com/t5/user/viewprofilepage/user-id/17972883">@pfarsonAA4ZQ</a>,&nbsp;#1.
