Tim,
Sorry, we currently do not have a rotate function in the contour area, but you can use the mirror function to achieve this by mirroring about a 45 degree line. Do the following:
1.) Go to Contour area and load your Geometry.
2.) Select Line Mode, key in the start point at 1,1 Enter, then for the end point, select the
INC radio button then key in 12,12 Enter (this line will be at 45 degrees).
3.) Now, select your outline geometry using Select -> Chain.
4.) Select Mirror, then on the mirror options dialog choose Line, Select OK, Select the 45 degree line.
5.)The mirrored geometry will show in yellow, Press Esc to exit mirror.
6.) Now, delete the original geometry and you should be good to go.
