Datum Plane Offset

Datum Plane Offset

Datum Plane Offset

(OP)
All,

I have a strange one.  When I offset a datum plane the orientation rotates -90deg about the Z-Axis.  Is this a glitch or is there value that I am not seeing.

RE: Datum Plane Offset

In which direction are you offsetting the plane?

(OP)
Positive direction.

RE: Datum Plane Offset

Hi,
   I have had a similar problem.   I don't know if it's a glitch or not.   For me, the Datum plane would reverse it's vector if it was Parallel to a face/plane and through an edge.
  The fix I came up with was to make the Datum parallel to another datum Plane (vector control) and through a Datum Axis.   The Datum Axis direction is driven by a Datum plane also, but on the edge in question. (Perpendicular to Datum/through point)  Now, when I make updates to my model I don't worry so much about the datums "flipping" and causing sketches to fail.   
   I would suggest you make sure that the Datum is either relative to another (Fixed) Datum or from a face you are sure will always be there on future edits.

Bubbers.
