Hi Mala, sorry I'm not understanding the problem. It's just a normal fact of geometry and
mathematics that the projection of a rotated object does not keep equal distances in the projected view.

For example if you have a square in the Top view:



If you rotate it so that the plane of the square is not aligned with the top view:



Then the projection of it in the top view will not be a square with equal length sides anymore:



Your lofts have equal distances in 3D but they are at an angle to the top view so it is normal that the
projected lengths in the top view will not be equal.
