I was trying to understand 3d tool, so I have drawn a square and then make a symbol, and select rotate 3d tool...but something unexpected happens:
if I rotate along x axis the square is not simmetric along y axis. Try to explain better:
this is the square, if i rotate along x, i'm expecing to become a isosceles trapezoid (simmetric along the y axis), but is scalene instead
changing the starting point of the 3d cursor before rotating doen't change this.
have i made some mistake or is a bug?
By the perspective, it appears as though the square is not centered horizontally in respect to the vanishing point.
Here is an article that discusses changing the vanishing point: http://www.adobepress.com/articles/article.asp?p=1247261&seqNum=4
