Working with Blocks, BlockAttributes, EntityGroups, References, and Hyperlinks

This chapter describes how to:

• Create and Insert Blocks. Blocks bind entities together to form a single entity. You can insert internal Blocks and external drawings as Blocks into drawings.
• Link BlockAttributes to Blocks. BlockAttributes are entities that let you link labels or variable text information to Blocks.
• Group Entities. EntityGroups are collections of entities (similar to Blocks) that are treated as one. Unlike Blocks, EntityGroups are not designed for repetitive insertions.
• Use References. References attach a separate drawing to the current drawing.
• Edit Components. In-place editing lets you modify the definition of referenced Blocks or externally referenced drawings.
• Attach Hyperlinks. Hyperlinks associated to entities provide jumps to Web sites, email addresses, drawing files, or user-defined views.

The Insert toolbar contains tools to insert Blocks, Referenced drawings, and Referenced raster image files. It also has a tool to save entities and convert Blocks to file.
