Traditional x,y,z axes orientation to North/South/East/West

Traditional x,y,z axes orientation to North/South/East/West

Traditional x,y,z axes orientation to North/South/East/West

(OP)
Given that positive Y usually points up skyward in various packaged engineering programs, then what is the usual orientation of X and Z relative to 'Plant' North?

RE: Traditional x,y,z axes orientation to North/South/East/West

usually?  for example...

RE: Traditional x,y,z axes orientation to North/South/East/West

X normally goes left to right horizontally, Y goes bottom left to top left vertically and Z goes straight up your nose..

RE: Traditional x,y,z axes orientation to North/South/East/West

only if you're triple jointed

(but then you auto types are, judging by the way you install bits and pieces under the hood)

and your orientation would have Zed (your thumb) horizontal pointing backward (presumably more aligned with your mouth)

and course then it depends on which way you're facing for which way is North ... since i like Zed up, I'd have X east and Y North (unfortunately triple jointed too !!)

Based on plant north you say.
Are you looking at a drawing sheet here, or are you looking at the bed of a CNC machine? and which way are your fingers pointing?

A very good point.

All said, there must be some "convention" or "generally understood sense" mentioned somewhere. Get googling, maybe?

One cannot trivialize the importance of this point - life could be much simpler if only such things were clearly defined somewhere for all to follow.

RE: Traditional x,y,z axes orientation to North/South/East/West

I generally assume a right hand coord axis arrangement with the y-axis pointing north... and z-axis upwards.  I've often seen LH Coord systems with z-axis downwards for geotech stuff, and I don't know if there's a real standard.

Ask the Australians, they may not have the same view. Have you ever seen an Aussie map of the World ? amazing !

RE: Traditional x,y,z axes orientation to North/South/East/West

Is "south" Australian for "north" ?

RE: Traditional x,y,z axes orientation to North/South/East/West

Then again, they are looking up at the world from down under, aren't they? Very understandable.
