| Basics of Coordinate Metrology Unit 5: Geometric Combinations - Distance (Part 1) | Step 2 of 8 |
| Distance | Point | Line | Plane | Sphere | Cylinder |
| Point |  The distance vector is equal to the difference of the local vectors of the two points |  The distance vector is perpendicular to the line. |  The distance vector is perpendicular to the plane. |  The distance is the distance of the sphere center from the point. |  The distance is the distance of the cylinder axis from the point. The distance vector is perpendicular to the cylinder axis. |
| Line | The distance vector is perpendicular to the line. |  The distance vector is perpendicular to both lines in space. |  The distance vector is perpendicular to both the line and the plane. |  The distance is the distance of the sphere center from the line. The distance vector is perpendicular to the line. |  The distance is the distance of the cylinder axis from the line. The distance vector is perpendicular to both the line and the cylinder axis. |
| Plane | The distance vector is perpendicular to the plane. | The distance vector is perpendicular to both the line and the plane. |  The distance vector is perpendicular to both planes. For planes to have a distance > 0, they must be parallel. |  The distance is the distance of the sphere center from the plane. The distance vector is perpendicular to the plane. |  The distance is the distance of the cylinder axis from the plane. The distance vector is perpendicular to both the plane and the cylinder axis. |
