gettype

I believe there are several objects that provide getType methods - which are you calling it from?

I''ll assume you are trying to get the type of model document.

2012 SOLIDWORKS API Help - GetType Method (IModelDoc2)

Notice the return value is a swDocumentTypes_e: 2012 SOLIDWORKS API Help - swDocumentTypes_e Enumeration

This is just an enumeration that the solidworks library defines; basically like assigning integers to variables but more memory efficient because it (should) be handled during compilation rather than run-time.

If you are troubleshooting something, it can be helpful to set up select case routines for printing the type to the immediate window.

select case swModel.getType

     case swDocNONE

          debug.print "swDocNONE"

     case swDocPART

          debug.print "swDocPART"

     case swDocASSEMBLY

          debug.print "swDocASSEMBLY"

end select
