You can group objects to create block definitions in the current drawing, or you can save the block as a separate drawing file. When you define a block, you specify the base point, the objects to group, and whether to retain or delete the objects or convert them to a block in the current drawing. You can also enter a text description and specify an icon used to help identify the block definition in AutoCAD DesignCenter. Block definitions are one of many nongraphical objects saved in a drawing.

A block reference can contain other blocks nested within it. For example, you can insert a drawing of a mechanical assembly that contains a housing, a bracket, and fasteners, with each fastener composed of a bolt, washer, and nut. The only restriction on nested blocks is that you cannot insert or create blocks that reference themselves. Continue reading →

Blocks can be defined from objects that were originally drawn on different layers with different colors, linetypes, and lineweights. You can preserve the layer and property information of objects in a block. Then, each time you insert the block, you have each object within the block drawn on its original layer with its original color, linetype, and lineweight.

A block is a collection of objects you can associate together to form a single object, or block definition. You can insert, scale, and rotate a block in a drawing. You can explode a block into its component objects, modify them, and redefine the block. AutoCAD updates all current and future instances of that block based on the block definition.

A composite tolerance specifies two tolerances for the same geometric characteristic of a feature or features that have different datum requirements. One tolerance relates to a pattern of features and the other tolerance to each feature within the pattern. The individual feature tolerance is more restrictive than the pattern tolerance.
