In-Depth Information
a sample door symbol and a table to which the symbol refers. The standard door-type symbol
suits this purpose nicely because it's an object that you can set up and use as a block indepen-
dent of the Door block.
FIGURE 12.1
A door symbol tells
you what type of
door goes in the
location shown.
Usually, the sym-
bol contains a
number or a letter
that is keyed to a
table that shows
more information
about the door.
A door symbol placed by a door in a floor plan
refers to a specification in a table in another drawing.
Adding Attributes to Blocks
In the following exercise, you'll create a door-type symbol, which is commonly used to describe
the size, thickness, and other characteristics of any given door in an architectural drawing. The
symbol is usually a circle, a hexagon, or a diamond with a number in it. The number is generally
cross-referenced to a schedule that lists all the door types and their characteristics.
You'll create a new block containing attribute definitions in the file for which the block is
intended: the Plan.dwg file. You may also use the 12a-plan.dwg file. You'll create the block in
the file so you can easily insert it where it belongs in the plan.
First, you open the Plan.dwg file and set up a view appropriate for creating the block with
the attribute:
1.
Open the 12a-plan.dwg file, which can be found on the companion website, www.sybex
.com/go/masteringautocadmac. Metric users can use the file 12a-plan-metric.dwg.
These are similar to the Plan.dwg file you've created on your own, with a few additions
to facilitate the exercises in this chapter.
