When you make a copy of a block from an Xref, AutoCAD needs to assign that block a name.
The Create Unique Layer, Style, And Block Names option tells AutoCAD to use the original
block name and append a $#$ prefix to the name (# is a numeric value starting with zero). If
you were to import the Bath block, for example, it would become $0$bath in the current draw-
ing. This ensures that the block maintains a unique name when it's imported even if there is a
block with the same name in the current drawing. If you use the
BINDTYPE
system variable
and then type
1
, the original name is maintained. If the current drawing contains a block of the
same name, the imported block uses the current file's definition of that block.
The Bottom Line
Assemble the parts.
Technical drawings are often made up of repetitive parts that are
drawn over and over. AutoCAD makes quick work of repetitive elements in a drawing, as
shown in the first part of this chapter.
Master It
What is the object used as the basic building block for the unit plan drawing
in the beginning of this chapter?
Take control of the AutoCAD display.
Understanding the way the AutoCAD display
works can save you time, especially in a complex drawing.
Master It
Name the command used to save views in AutoCAD. Describe how to recall a
saved view.
Use hatch patterns in your drawings.
Patterns can convey a lot of information at a glance.
You can show the material of an object, or you can indicate a type of view, like a cross section,
by applying hatch patterns.
Master It
How do you open the Hatch And Gradient dialog box?
Understand the boundary hatch options.
The boundary hatch options give you control
over the way hatch patterns fill an enclosed area.
Master It
Describe an island as it relates to boundary hatch patterns.
Use external references.
External references are drawing files that you've attached to the
current drawing to include as part of the drawing. Because external references aren't part of
the current file, they can be worked on at the same time as the referencing file.
Master It
Describe how drawing files are attached as external references.
