Hi @talha_ozdemir ,
Welcome to the Forums, I see you're using Revit 2022 and you're facing this issue on a custom Familie you developed.
Could you kindly elaborate on this, so that other users can point to in the right direction/ or explain probable causes?
1. What kind of Family is this? maybe the template has certain restrictions.
2. Is it possible to post the family here so others can take a look at it?
3. From the looks of it, I assume it's a metal profile? What is your requirement like? Does it need to look like this in Detail as well as 3D or can it be simplified to just a rectangular profile in geometry? (May save you relative family file size).
A little more description would be very helpful to narrowing it down or finding a better workaround.
Cheers, K
