The following example illustrates the meaning of the storage location [Save location] setting option.
An error message Unknown variable:
If you have created a variable with the storage location [Save location] "Only in table [Only in table] " (storage in the tab/tac file) and want to use it in Sketcher, the error message Unknown variable appears.
Save the relevant variable with the storage location [Save location] "In geometry and table [In geometry and table] " (storage in tab/tac file AND 3db file).
-> Now the variable can be used in the sketch.
