How to get current space?

[JeffPaulsen]

I am working on a lisp routine and want to make an IF statement based on whether the user is in paper space or model space.

How do I determine the current space?

This seems like a basic request and I assume this information is stored in a system variable but a 10 minute search has come up empty.

You might try this routine.  It is the one I use.

(if(and(zerop(getvar"tilemode"))(= 1 (getvar"cvport")))(princ"\nPspace")(princ"\nMspace"))

Thanks guys.

I never have much time to work on lisp so I ended up making two routines for now, one for PS and one for MS.

I will take a cloder look at your suggestions when I have more time. I did test Paul's code at the command line and it was able to acuratley determine what space was current. I will probably look at this option first.

Yes, both TILEMODE and CVPORT must be investigated
to determine what space is current.

Only the CVPORT system variable need be tested:

(if (= 1 (getvar 'cvport))
    < user is in paperspace >
    < user is in modelspace >
)

Depending on program intent it can be handy to know if you are in floating modelspace.  Determining that requires more than testing only CVPORT.

Correct - TILEMODE must also be tested if it is necessary to differentiate between the Model layout & viewing Modelspace through a Paperspace Viewport, but I believe my above suggestion is the most succinct way to determine the current space, as the OP requested.

I suppose it doesn't have to be TILEMODE.  One could also use CTAB, since you can't rename the model layout.  Same difference in the end.
