https://forums.autodesk.com/t5/inventor-forum/horizontal-and-vertical-constraints-not-consistent-with-view/m-p/5612701#M377751 <P>My question/complaint is, "Why is up not consistent with the text on the view cube?"&nbsp;</P><P>&nbsp;</P><P>The responses I've gotten are, "the thin line is up" and, "it's a bit annoying, but it's done properly in Inventor."&nbsp;</P><P>&nbsp;</P><P>Neither of these address the fact that the "thin line" is horizontal when looking at the left and right faces of the view cube.&nbsp;</P><P>&nbsp;</P><P>Again I ask, why is up not consistent with the text on the view cube? I feel like the answers I'm getting are, "Up is arbitrary, but Inventor&nbsp;shows you which arbitrary direction up is!"</P><P>&nbsp;</P><P><STRONG>I have never seen any post explaining WHY up is sideways on either side of the YZ plane.&nbsp;</STRONG></P><P>&nbsp;</P><P>Granted, every direction is arbitrary until a datum is selected, but my point is that it would appear, based on the only data given (the text in the view cube), that UP would be UP relative to the text on the view cube.&nbsp;</P><P>&nbsp;</P><P>Maybe Inventor should change the view cube?</P><P><IMG title="Honest View Cube.png" alt="Honest View Cube.png" src="https://forums.autodesk.com/t5/image/serverpage/image-id/166190i087182E8D253F036/image-size/original?v=mpbl-1&amp;px=-1" border="0" /></P><P>The directions on the view cube, again the only point of reference anyone has, would lead you to believe that UP should always be the direction from the Bottom to the Top of the view cube, or else why would you call those sides the top or bottom? The view cube depicted above shows how Inventor treats UP in all sketches on the origin planes, though, where UP is defined as the direction from the Front to the Back of the view cube, and that does not make any sense at all.</P> Wed, 29 Apr 2015 15:13:08 GMT Anonymous 2015-04-29T15:13:08Z
