Issues with Viewport.CanAddViewToSheet method

Anonymous — Mon, 29 Apr 2019 08:49:32 GMT

Dear All,

Despite the fact, all the conditions for view placement on sheet are met, Viewport.CanAddViewToSheet method constantly returns false value;

bool result = Viewport.CanAddViewToSheet(view.Document, view.Id, sheet.Id);

However, if I try to place the view on the sheet without checking whether the view CanAddViewToSheet, everything works fine. I provide the same input arguments in both cases.

Viewport.Create(view.Document, sheet.Id, view.Id, new XYZ(0, 0, 0));

I have seen, that a year ago @Anonymous asked the same question in the post:

https://forums.autodesk.com/t5/revit-api-forum/how-to-add-views-on-a-sheet/td-p/7935024

and was not answered. Does anyone experienced similar issues with this method?

Edit: I use views of ViewPlan class

I tried the same code you provided in Revit 2020 and it returned true. Maybe your file has been corrupted or your sheet, the view has a problem about that method. Can you provide a sample file?

I hope this helps,

Recep.

Here is the file.

Views are placed on sheets only if this line is off: (full code is provided in the macro)

Does anyone?

I was looking for workarounds, and what I noticed is that views that are placed on sheet has the parameter:

'Sheet Number', whilst views that are not placed don't. Do you think this could be a good direction to check whether view is already placed on sheet?

@Anonymous , 5 years later - did you manage to figure it out?

Hi,

When a view belongs to a sheet Revit adds the Sheet Name parameter, otherwise, when the view does not belong to a sheet the Sheet Name parameter does not exist.

I implemented this simple method to check if it is possible to add a view to a sheet:

private bool CanAddViewToSheet(Autodesk.Revit.DB.View view) { ParameterSet parameterSet = view.Parameters; Parameter sheetName = view.get_Parameter(BuiltInParameter.VIEWPORT_SHEET_NAME); return !parameterSet.Contains(sheetName); }

Use:

if (CanAddViewToSheet(view)) { //Create }

Seems like you've passing parameters in the wrong order here. The sheet id should be the second, the view id should be the third parameter.

bool result = Viewport.CanAddViewToSheet(view.Document, sheet.Id, view.Id);
