Why Direction Matters when Digitizing Polygons in LP360

When drawing polygons it definitely matters if they are drawn clockwise or counterclockwise. Why you ask? Well, because polygons have a “sense” of direction. The right hand side of the vector used to draw a polygon is considered to be the “inside.” If you draw your polygon clockwise the right-hand side of the vector becomes the “inside” of the polygon. Likewise, if you draw the polygon counterclockwise the right hand side of the geometry is on outside of the polygon and the insider portion is now considered to be a “hole”.
