straighten object in coreldraw

let's say i have an object or a group of objects which was grouped/ungrouped/modified and grouped again and so forth so the initial angle of rotation is lost. is there a way to straighten this object on a horizontal line?

simplest example: make a rectangle, rotate it at any angle, convert it to curves and the rotation angle is lost.

  • My Match Vectors macro can be used for that type of "straighten" task.
