cutting of 2d elements in revit

[shimon]

Hello everyone!
I started drawing in revit a plant to the winds, so I inserted poroton 2d taken from the family detail elements, but of course at the meeting with the washings I need to cut the poroton. Can you do it? If so, how? Thank you in advance.

No, you can't. you have to solve with an appropriately cut item
