Model for Descriptive Geometry by A. Jullien - Angle of a Plane with Planes of Projection
Object Details
- Jullien, A.
- Description
- Given plane APA’, c’ is a point on the intersection line of the plane with the vertical plane. Point b on the horizontal intersection of the plane is chosen so it that bc’ is perpendicular to PA. Connect b and c’ to from the red string. The horizontal projection of bc’ is bc and the vertical projection is cc’. By rotating bc’ about bc to the horizontal, point C1 is found. Now angle cbC1 is the angle of the plane with the horizontal plane. Similarly, the angle bC1C is the angle with the vertical plane.
