I've made the following model with which I hope to explain the PTC coordinate system to 5th Graders. I've succeeded only in confusing myself. Maybe you can help.
The file is attached. Created with Creo Parametric 3.0 M070 Academic. I think this a right hand system as pictured, I've extruded X+, X-. Y+, Y-, Z+ and Z-. I want to extrude (20mm) FRONT+, FRONT-, TOP+, TOP-, RIGHT+ and RIGHT_ on the planes I presume that FRONT+ is on the Y+ side of the FRONT plane. Am I on the right track?
It seems to me that the default system in Creo Academic is a left handed system!!!
