How find out space status of a viewport ?

[mehdi-guida]

Hi,

I have 4 viewports in a layout. Space of One of them is Model (highlighted and is in model space).

Is there any system variable or .Net code to find out which one is in mode space and which one is in paper space?

Thank you

Editor.ActiveViewportId;

I would first check the CVPORT system variable. If it is 1 then no viewports are currently active in modelspace.

Thank you for reply.

As you said If CVPORT is 1 then no viewports are currently active in modelspace. but I need to know which one is active?

Then use the Editor.ActiveViewportId; property...

Thank you

I used this property but that always return an ObjectId even in empty layout !

The Layout is a Viewport. That is why CVPORT will return 1 when no viewports are active to modelspace. And also why I said you should check that sysvar.
