Types of Drawing Documents

Drawings are normally created with the model resolved; that is, all information about the model is available in the drawing document. You can improve performance in creating, opening, and working in drawing documents with the following:

Lightweight Drawings A subset of model data is loaded into memory; the remaining model data is loaded as required. In a new drawing, create a lightweight drawing by specifying draft quality views. Opening a lightweight drawing is faster than opening the same drawing with fully resolved models. You can change between resolved and lightweight mode while in a drawing.
Reduced display data drawing files Tessellated data for shaded and draft views is not saved with drawing documents when you clear the drawing option, reducing file size. The data is available in the model file.
