Create and Modify Blocks
A block definition is a set of objects that are grouped together as one named object with a
base point and unique properties.
Define Blocks
You create blocks by associating objects and giving them a name.
Create Blocks Within a Drawing
After you define a block in a drawing, you can insert a block reference in the
drawing as many times as necessary. Use this method to create blocks quickly.
Each block definition includes a block name, one or more objects, the coordinate
values of the base point to be used for inserting the block, and any associated
attribute data.
The base point is used as a reference for positioning the block when you insert
it. Suppose you specify that the base point is at the lower-left corner of an object
in the block. Later, when you insert the block, you are prompted for an insertion
point. The block base point is aligned at the insertion point you specified.
The block definition in the illustration comprises a name, PLUG_VALVE, four
lines, and a base point at the intersection of the two diagonal lines. For an
explanation of the schematic representation shown, see
Overview of Blocks on
page 405.
