Orientation of newly attached HUDs

Hi,

A have been making a HUD and am confused about the HUD orientation when first attached.

Here is my scenario..

1. I work assembling the prims for my HUD. I link them all together.

2. I attach the assembly as a HUD

3. The HUD attaches but is rotated so I am just seeing the side of it. I edit the attached HUD so I see the front.

My question is ... when you initially attach and object as a HUD which face to "see". I
have tried experimenting with this but cannot understand how it works. I am not sure if it is influenced by where you are standing when you "attach".

Any hints?

what I usually do when first building a new hud is make one prim and apply my test texture to it. then I attach it to the HUD and see what side comes up. that then becomes my working face for the rest of the HUD, if it involves multiple prims

Along the North-South-East-West directions, the west side of the object is what becomes the HUD surface. For new cubes this will be side #4.

If you rotate the object, whichever surface ends up on the West side now becomes the new HUD surface.

If you are facing east, and the object is in front of you, then the side you see is the HUD surface. So when building HUDs, open the World Map and orient yourself to face East. That way there are no surprises.

Another way to look at it, on the edit mode's X/Y/Z axes, the side where the red X-axis arrow points into the object is the HUD surface.

See my crude visualization of which side becomes the HUD surface.

Not a crude visualization at all. Excellent work. Thanks for illustrating it so well!
