Offset gizmo range sometimes doesn't include the original location

[zarakon]

The Structural Pylon is the worst offender here. As soon as you move it in any direction, it jumps way inside whatever it's placed on, and can't be moved back out to its original location

Also happens to the TT-18A Launch Stability Enhancer, the TT-70 Radial Decoupler, and to a lesser extent the Gigantor XL Solar Array

You can use the Space key to reset any gizmo modifications on the currently selected part.

As for the actual issue, though... it might be worth seeing if it's been reported on the Tracker already. If not, a concise report (preferably including screenshots) would be awesome, if you have the time.

There's an invisible grid that parts snap to, so when you see your part move away from its starting point it's because it's snapping to the nearest grid point.

Sal is correct, there are underlying grids that the parts will snap to, both local to the part and absolute to the ship.

If you don't want it to snap to one of these grids when you offset, turn angle snap off before pulling on the offset gizmo's axis markers.

I know, I actually created a separate issue for what I think is wrong with grid snap - http://forum.kerbalspaceprogram.com/threads/104196-Offset-Gizmo-snaps-in-directions-other-than-desired-movement

This is something else, and it happens even when snap is turned off. All of the affected parts have portions of their model that are not highlightable. It seems that the game uses the highlightable mesh to set the limits of the offset tool, so if that area is normally not adjacent to the attachment point, it gets forced inward as soon as you try to move it.

I'll try to record a short video showing it

You mean the slight bevel to the bounding box?

Video:

Some parts where the attachment point is not highlightable behave poorly when using the offset gizmo.

Note that angle snap is always turned OFF when I'm using the offset tool. The part not only moves inward as soon as I try to move it a different direction, it also can't be moved back to the original position without resetting it entirely.
