To avoid close proximity between building envelope and a nearby power line, geometric methods to compute normal distances from spatial point, plane and line to a parabola, approximating the catenary, are developed using projection onto ideal planes. Then line geometry is applied for the first time...

The distance from the origin to a point P(x, y) is given by (blank). Find the distance from the point (5, 9, -5) to each of the following: (a) the xy-plane, (b) the yz-plane, (c) the xz-plane, (d) the x-axis, (e) the y-axis, (f...
Planar—The distance calculation will be performed on a projected flat plane using a 2D Cartesian coordinate system. This is the default method. Geodesic—The distance calculation will be performed on the ellipsoid. Regardless of the input or output projection, the results will not change. The Ver...
