The AREA command lets you calculate the accumulated area of close polylines, ellipses
and circles from the drawing in a way of successive pickups. It provides three modes of
area calculation; namely, they are:
Once the AREA command is entered, it will prompt
Area -- Add/Subtract/<Entity>:
asking you to pick up the entity for the area calculation. Valid entities are
polylines, circles and close ellipses. If the polyline is not closed, it will be taken as
a close polyline made by adding an additional line joining its start point and end point.
You may enter the sub-command option "A" and "S" to switch to the Add
mode and Subtract mode, respectively. AREA will change the prompt to
Area -- Entity/Subtract/<Add Mode>:
Area -- Entity/Add/<Subtract Mode>:
Once a valid object is picked up, AREA will calculate the area result and report it in
the command area in the form as
Area = xxx.xxx, Total Area = xxxx.xxx
and continue the prompt again, until you press space bar or <Ctrl/C> to terminate
Other type of area calculation
For complicated area formation, use BPOLY command to obtain the total area information.
The AREA command is an external command provided by the TCL program file
"AREA.TCL" or "AREA.TCA". Either file must be present in the COMMANDS
sub-directory where the TwinCAD resides. If you can not issue AREA command, you may solve
the problem by copying the "AREA.TCL" to the COMMANDS sub-directory.
