I have been making great progress with Wizo Script and can see that it will be my main method of working in Alibre. BUT . . . . when I put 2d-splines into sketches on the ZX-Plane (or parallel planes), the sign of the Z-coordinates had their sign reversed.
I've attached a zipped script to demonstrate this. It first draws 3D points and splines (which are drawn as expected) and then 2D splines. The 2D points that control the 2D splines are entered with negative z-coordinates, but are drawn as though positive values had been provided!
Aside from this happening in Wizo Script it appears to also occur with the 'insert from file' function. I understand that the "insert from file" capability was originally an add-on contributed by an Alibre User. In both of these cases it should be possible to easily rectify the sign reversal.
For WizoScript, so as not to mess up all the existing scripts that might anticipate this sign reversal, I would suggest the ability to include a flag at the top of a script to indicate that z-coordinates should be drawn as input. For "insert from file" a checkbox could be added to indicate a wish to preserve z-coordinates.
As far as what happens, or should happen, on planes that are not parallel to the 3 major planes, I have no idea. It might be too mind bending to consider, but for the standard planes and their parallels, up and down should not be confused. (says me!)
