hi @denniswave I started converting the 3D floorplan to 2D by using your solution..but getting the cross floorplan as result.I.e walls are cross instead of horizontal,vertical means

hi@denniswave,it has generated the cross floorplan..how to make that straight.?

@AkshayBagekari I tried the solutions for the cross floorplan that @denniswave and @Brent185 suggested, but I couldn't solve it.. and are right, but solutions depend on how each person thinks. Everyone's thinking process may be different. I aimed for a straightforward output - So, I added a rotation gesture(UIRotationGestureRecognizer) and checked the camera angle when the user rotated it. I compared that angle with the angle of each surface, and it matched the angle of the longest continuous surface. , I set that rotation angle as the camera angle. I didn't rotate the whole surface; I just changed the camera angle. Finally, I got the correct output. I added the rotation gesture only for testing purposes to see if it appears straight at a certain angle, which means you don't need to add the gesture. For example :- by setting camera rotation. self.camera?.zRotation = largesurfaceAngle
