Terms | Definitions |
|---|---|
 Annotate | To add explanatory notes to. |
| Browser | A sequential record of the construction steps in a 3D modeling program. |
| CAD (Computer-Aided Design) | The use of a computer to assist in the process of designing a part, circuit, building, etc. |
| Chamfer | A small angled surface formed between two surfaces. |
| Coincident | Occupying the same area in space. |
| Collinear | Lying in the same straight line. |
| Concentric | Circles or arcs that share the same center. |
| Constraint | A limit to a design process. Constraints may be such things as appearance, funding, space, materials, and human capabilities. A limitation or restriction. |
| Counterbore | A cylindrical recess around a hole, usually to receive a bolt head or nut. |
| Countersink | A conical-shaped recess around a hole that is often used to receive a tapered screw. |
| Design | An iterative decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems. |
| Dimension Constraint | Used to describe the size and location of individual geometric shapes. |
| Documentation | The documents that are required for something or that give evidence or proof of something. A drawing or printed information that contains instructions for assembling, installing, operating, and servicing. |
| Edit | A change or correction made as a result of editing. |
| Extend | Make larger in area. |
| Feature | A distinctive attribute or aspect. |
| Fillet | A rounded interior blend between two surfaces. |
| Fabricate | Construct or manufacture an industrial product. |
| Fix | Attach or position securely. |
| Functional | Designed to be practical and useful. |
| Geometric Constraints | Restrictions applied to geometric entities; for example, horizontal, parallel, perpendicular, and tangent. |
| Horizontal | Parallel to the X axis. |
| Isometric | A form of pictorial drawing in which all three drawing axes form equal angles of 120 degrees with the plane of projection. |
| Mockup | A model devised to expose its parts for study, training or testing. |
| Model | A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original. A model is often used to test ideas, make changes to a design, and to learn more about what would happen to a similar, real object. |
| Offset | The amount by which something is out of line. |
| Parallel | Lines, planes, or surfaces side by side and having the same distance continuously between them. |
| Perpendicular | At an angle of 90˚ to a given line, plane, or surface. |
| Polygon | A closed geometric figure in a plane formed by connecting line segments endpoint to endpoint with each segment intersecting exactly two others. Polygons are classified by the number of sides they have, such as a triangle has three sides, a quadrilateral has four sides, and a pentagon has five sides. |
| Profile | An outline of something as seen from one side. |
| Prototype | A full-scale working model used to test a design concept by making actual observations and necessary adjustments. |
| Revolve | To move in a circle about a central axis. |
| Right Triangle | A triangle that has a 90 degree angle. |
| Rotation | Turning around an axis or center point. |
| Sketch Plane | The surface that 2D profiles can be sketched on. |
| Specification | A detailed description of the design and materials |
| Tangent | A straight line or plane that touches a curve or curved surface at one point. |
| Trim | Cut off irregular or unwanted parts. |
| Vertical | Parallel to the Y axis. |
