/* Constructing Physical Structures Using Standard Geometric Objects */
In view of the drawing process and geometrical properties, objects can also be divided into two groups: dimensional objects and nodal objects. A dimensional object is characterized by a local coordinate system (a center and local X-, Y- and Z-axes) and a number of dimensional parameters such as length, width, height, radius, etc. Examples of dimensional objects are box, sphere, rectangular strip, line, helix, etc. A nodal object is characterized by a set of points (nodes). [[EM.Cube]]'s nodal objects include polystrip, polyline, NURBS strip, NURBS curve and polymesh objects.
CubeCAD provides a diverse set of standard geometric objects that are fully parameterized. In addition to the center coordinates and rotation angles, these objects have a variety of dimensional parameters that are used to set and control their size and geometrical shape. More complex objects can be created by editing and combining these basic shapes. Objects can be created by clicking on one of the object buttons on the '''Object Toolbar''' or from the '''Object → Solid''', '''Object → Surface''', or '''Object → Curve''' menus. Once an object tool is selected, left click anywhere on the work plane to draw the object. The following table show a list of [[EM.Cube]]'s standard solid, surface and curve objects:
