Lines by Point Number
This feature allows you to draw lines and/or arcs based on the
points in the coordinate file.
Prompts
If you choose this option and a coordinate file is not open, you
will be prompted to open one.
You will be prompted at the command line to enter the coordinate
point IDs that define a line/arc or a series of lines/arcs.
You may type the point IDs at the command line or pick points on
the screen.
Enter Point Sequence
(point group/Reset/sNap on) (last point = <72>):
Once a point is selected the
command line will change to a new group of options
(cLockwise curve/ccW curve/Point group/Reset/sNap on) (last point =
<72>):
Once finished plotting points simple hit<Enter> and the
command line will clear.
Point Input: When entering
a point sequence specifying a line/arc the following input forms
are acceptable:
34: Either specifies the
starting point of a line or, if this is a continuing series of
lines, draw a line from the previous end point to point 34 and
occupy point 34.
6-9: Draw a line from point
6 to 9 and occupy point 9.
-4 : Draw a line from the
previous end point to point 4 but remain at previous end point.
L: Specify a cLockwise
curve. The previous end point is assumed to be the PC of the
curve. The next point specified is the center or radius
point of the curve and the next point entered is the PT of the
curve.
W: Specify a counter
clockWise curve. The data entry sequence is similar to a clockwise
curve.
P: Use a Point group to
specify the lines/arcs. You will be asked to pick the point group
file using a file dialog box.
R: Reset the “last point”
to none
N: Toggles the CAD snap
command on or off
If you choose to use a point group file, lines will be drawn from
point to point in the order specified in the point group file (see
the CGMngmt chapter for information on point group files).
If you do not want to type in the point IDs to define the
lines/arcs, you can select the points from points that are plotted
on the screen using your mouse. (see Plot Points and
Symbols).
Note: To specify an arc to
be drawn pick the PC point of the curve then enter either
L <Enter> for
clockwise or W
<Enter> for counter clockwise curve. When prompted, pick the
radius point and then pick the PT.
