相切的三个平面

Synopsis

obj = SPHERE/TANTO,plane1,plane2,plane3,CENTER,point,RADIUS,r

Description

Creates a sphere tangent to three planes by specifying the three previously defined planes and a previously defined point which lies in the three dimensional quadrant (octant) of the center of the sphere.

For the sphere to be tangent to all three planes, the planes must all be at right angles to each other.

Parameters

Parameter

Description

TANTO

Minor word that indicates that the spherical fillet is to be tangent to three planes.

plane1,plane2,plane3

Three existing intersecting planes.

NOTE: The sphere octant is tangent to planes 1 and 2 and a plane normal to planes 1 and 2 through the intersection point of the three planes.

CENTER

Minor word that indicates that a point is to be supplied which approximates the location of the sphere center.

point

A previously defined point which approximates the location of the sphere center and determines which of eight possible spheres to create.

RADIUS

Minor word that indicates that the radius of the sphere is to be specified.

r

A positive value which establishes the sphere radius.
