Examples include a sphere, an extrude, or a rectangle created on the layer plane. A 3D symbol definition consists of 2D and/or 3D objects that are created on a layer plane.After placement, the symbol instance exists on any plane (just like any other planar object), and displays in any view. Examples include text, a rectangle, an arrow, or a bitmap, placed on the screen plane. A 2D symbol definition consists entirely of 2D objects that are created on the screen plane.It may be helpful to review Concept: Objects in the screen plane and in the layer plane. You can also create your own symbols.Ī symbol definition can be created from one object or many objects. Vectorworks products provide thousands of symbols as part of the available content. When a symbol definition is placed into the drawing, a symbol instance is created (see Concept: Object instances, definitions, and styles). The objects are incorporated into a symbol definition, which is a resource that can be selected from the Resource Manager and Resource Selector. Symbols Concept: Vectorworks symbols What are symbols?
