View classes in sheets and view templates.

[franjavigarciavalencia]

Hi, I have a couple of questions I'd need some help with:

-First, how would you check if any kind of view is being used already in a sheet (for instance, a ViewPlan or a View class)? This would be mainly to check if you are trying to create a sheet with a view already in use.

-Second, what is the class or how do you access view templates? I'd like to apply one to a View but I do not know what to use and can't seem to find anything clear.

Thank you in advance for your help!

To answer the first question, you can use the ViewSheet GetAllPlacedViews method:

If it gives you the opposite of what you need, you can invert the relationship (post from 2008!):

To answer the second, do these two recent threads help?

• Get all Views that accept View Template -- https://forums.autodesk.com/t5/revit-api-forum/get-all-views-that-accept-view-template/m-p/9105369

Thank you for the help.

For the first issue I had I used the method you suggested and it worked like a charm.

For the second one, I solved it using RevitLookup and used the ViewTemplateId and IsTemplate properties of the View class, in case anyone needs or wants to know. Thank you for your suggestions anyway!
