PEDIT
You can use the PEDIT command to create a closed pline from several line and arc seg-
ments. To do so, issue the command, pick one of the lines, answer Yes when asked if you
want to turn it into a pline, select the JOIN option, and pick the other segments with a
window. Remember:
• All segments must be touching but not overlapping.
• You can’t have segments on top of each other.
• The resulting pline should be closed.
• Use the Fuzz option of MPEDIT if your geometry isn’t exact.
ENTITY SELECTION
When you use the AREA command, it’s easier to select objects than it is to pick points.
To find the area of a large object minus the areas of several smaller objects, you can use
the Add and Subtract options of the AREA command. Pay attention to the command
prompts. Type AREA↵A↵ followed by O↵, select the largest entities, and then right-click
when you finish; doing so adds the areas of all the objects you picked. Type S↵ to select
the Subtract option, followed by O↵ for Object, and select each object whose areas you
want to subtract.
QUICK AREA CALCULATION FOR COMPLEX FEATURES
It’s not unusual to want to find the area of an object with a large number of features
removed. It’s easy to miss one or more objects in the process. The quickest way to get a
total area when you have many areas to subtract is to create regions. If all the objects are
circles or closed plines, you can do this with the REGION command. If the shapes are
composed of anything else—lines, arcs, overlapping segments—use the BOUNDARY
command. Once all the shapes are regions, use the SUBTRACT command to create a single
region. Then you can select a single entity when using the Object option of the AREA
command.
The alias for the AREA command is AA, which doesn’t follow the normal pattern used for
other commands. Why not? A (ARC) and AR (ARRAY) are already taken. RENDER (RR) is the
only other alias with this format.
The variable PEDITACCEPT was added to AutoCAD 2005. If it’s set to 1, the user isn’t prompted
with the question Object selected is not a polyline. Do you want to turn it into
one? <Y>. Instead, the object is automatically turned into a pline. It’s possible that 1 will
become the default setting in a future release.
