Summary

Something I'm developing in Orchard, for my classes, to reinforce understanding of the 3D workspace. Showing the relationship between the 0,0,0 point and positive and negative grid locations. Grid 3D model is 1cm spacing.

• RGB=X,Y,Z for your axis colors.
  The Orchard link below if you want to demonstrate in a class or something, but for this, I should be remunerated handsomely because this is introducing some powerful concepts and training tools for the noobs.

The bottom of the grid plane can be raised on Z as one element and since the profile is triangular, the 'line thickness' can be made very thin.

Some pieces are floating a bit so supports are needed if you print it but it's more of a visual aid.
