Working with Blocks, BlockAttributes, EntityGroups, and References

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.
