Details
The Default Environment Variable "UGII_OLD_SKETCH" is not available form NX1899 onwards.
Solution
This variable was related to the old sketcher, which was referring to the Unigraphics pre-V13 user interface.
Setting this to "1" used to enable Unigraphics pre-V13 sketch user interface.
From Unigraphics NX 1.0 onwards, only 1 sketch creation user interface was available, so access to the pre-v13 (and pre-NX1) version of the sketch creation UI has been removed. (disabled through coding)
Customers who have pre-v13 sketches can still edit them via the "Edit pre-V13 sketch" icon, which is still available (but hidden by default).
Users will no longer be able to create a new sketch using the pre-V13 sketch UI.
Therefore, the UGII_OLD_SKETCH variable is no longer valid in Unigraphics NX1. onwards.
So this was an redundant environment variable from NX1.0 onwards,
So this variable has been removed.
