| Mirror tools | allow selected shapes to be copied or flipped about a defined center |
| Copy or Clone | tools allow selected objects to be reproduced in their exact size and form. |
| Deformation tools | emulate the process of working a piece of clay |
| Move | is used to advance an object from one position to another |
| Snap | allows the object to be moved only at set intervals of distance |
| Rotate | refers to tilting or changing the direction that an object is facing |
| Transformations | are actions that scale, rotate, and move objects |
| Scale | changes the size or proportions of an object along one or more axes |
| lathe | operations allow the user to create a 2D shape and then revolve it around an axis |
| lofting | allows you to create a 2D shape and then extend it along a path or curve to form a 3D object. |
| Boolean | tools or operations are used to create objects by combining, subtracting, or determining the common intersections of various objects such as primitives |
| Union or Addition | is used to combine objects together into one new object |
| Subtract or Difference | is used to remove part or all of an object where objects overlay each other. |
| Intersection | is used to calculate the overlapping volumes of objects so that the overlap becomes the object. |
| defaults | Values provided automatically by the software |
| Polygons | are plane figures made with three or more straight sides |
| Splines | curves or polygons that are composed of segments that can be manipulated by control points placed along the curve |
| Control points | may be made “active” and then dragged using a handle attached to the point. |
| 3D modeling programs | contain certain basic geometric shapes that can be combined with or subtracted from other shapes to form more complex objects |
