in wildfire 5.0 I think the only one is to disable the config options that allow the use of sketch constraints, (e.g. sketche_equal_length_constraint no).
you can also do it temporarily by sketch > options.
I'm sorry, though.
Bye.
in the wf5 no longer exists, in the wf4 the option was still present.
have added commands of substitution of geometric entities and reference much more effective than the old style.
Also if you pull a line and click once with the right you can always unleash yourself at any time by the inent manager.
