Hello, I recently updated Creo View 6.1 from 4.0. I no longer have the markup tab in the ribbon. Is it hidden somewhere, or am I missing something?
I don't believe that the OS should dictate whether or not this is available (although it may be possible). It sound more like you may have installed Creo View Express which does not have markup capabilities like Creo View Lite or Creo View MCAD has.
creo view 6.1 is not supported on Win10.
For Win7 should install creo view 5.1 or less.
those words have been tested and confirmed by myself in both direction.
