The H-Factor

We got a comment from a customer that he would like to turn off our default Object Snaps temporarily when using certain HydraCAD tools. There is an easy way to do this – AutoCAD has Temporary Overrides built in; these are stored in the CUI file.

Overrides differ from toggles (F3 for OSNAP, F8 for ORTHO, F9 for SNAP) in that they do not have to be turned off and then back on. Instead, if a key combination is held down then the override kicks in; if it is let up, the override disappears. Look in the CUI under Keyboard Shortcuts/Temporary Override Keys

To remove the osnap (and ORTHO and SNAP), simply hold down SHIFT+D (righties) or SHIFT+L (lefties) to disable all snapping and tracking. Let go, and the osnap returns.
