Incorrect icons for section views

Is it me, or are the icons for the YZ and ZX section view buttons mixed up? The labelling seems correct - just the icon appear to be wrong.

Depends how you have oriented the workspace. The icons do look switched if workspace in 'front view'.

It does seem a little odd given it defaults to a different orientation on starting a new part.

I suspect that a part of the problem here is that the X-Y Plane presmts as a "vertical" plane in most CAD products (courtesy of the architects who were (Federally) funded to control "CAD development" through much of the 1980's whereas "Industry-types" assume the X-Y Plane to be the "horizontal" basis of their work. -- Lew

Hello Lew,
is it also ok to suspect the first plots on a computer screen have been 2D (x-y like them on paper at school...x up and y to the right), then the third dimension vector was simply added in a direction to the screen, to let the geometry grow out of the monitor... and there you have the right hand rule and so on...
its the same orientation on e.g. a milling machine or 3D-printer were the part "grows" out of the table.
Regards
Stefan

Hi Stefan -- The convention for 2D Axis is the X+ axis going horizontally to the right and the Y+ axis 90° anti-clockwise to that to make the Right Hand Rule effective. Add a 3rd Dimension to that and the Z+ axis goes "up" (the direction your right hand thumb points when your "fingers" sweep from X+ to Y+. [That is the definition of the Right Hand Rule.] -- Lew
