| Absolute Coordinate | A method of plotting points whereby distances are measured from the origin. |
| Axis | Primary direction in a coordinate system. |
| Cartesian Coordinate System | A rectangular coordinate system created by three perpendicular axes labeled X, Y, and Z. |
| Origin | The point at which axes intersect. |
| Polar | A method of plotting points whereby distances are measured using angles. |
| Relative | A method of plotting points whereby distances are measured from the previous point. |
| Coincident | Two points fixed together. |
| Collinear | Lines or points belonging to the same line or an extension of that line. |
| Concentric | Arcs and circles sharing the same centers. |
| Coplanar | Belonging to the same plane. |
| Fixed Point | Locking a point to a position relative to the sketch coordinate system. |
| Horizontal | A line parallel to the horizon. |
| Parlallel | Two or more lines having equal distance between them. |
| Perpendicular | lines forming a 90 degree angle. |
| Tangent | A line that intersects a circle or an arc at one and only one point. |
| Vertical | Perpendicular to the horizon. |
