How to get access to data from "Visiblity/Graphics"?

Dear Artur,

Thank you for your query.

Have you tried searching the Internet for this information?

I get quite a lot of hits searching for "revit api visibility graphics":

https://duckduckgo.com/?q=revit+api+visibility+graphics

You probably should be more precise about what exact settings you wish to access, though.

Here is one specific example from The Building Coder:

There are many more, though.

I hope this helps.

Best regards,

Jeremy

Hi Jeremy,

Thank you for your reply.

What I'm exactly looking for is list of model categories hidden in a given view.

I'm aware of:

GetCategoryHidden(ElementId categoryId);

But maybe there is a better way than iterating through all categories and check if it is hidden?

Dear Artur,

Thank you for your update.

I am not aware of a better method.

Check the View class methods:

There is also a Visible property on the Category class:
