When I print my sections and add a collar plan, the rotated map view in the collar plan window has not correctly rotated the structural symbols.
Solution
This is caused by MapInfo not rotating symbols, when an affine projection is applied to rotate the map. Everything else in the map is rotated.
As a workraound, you can open the structural symbols in a blank map in the collar area. and then use IMAGES>Map to Image to save a image of the structural symbols. If you then add this image to the collar plan view, it will be rotated correctly.
