• T-Crv : creates a curve with a
specified incoming tangent from the
next two points that are stored with a
description associated with T-Crv.
When the second point is stored, the
prompt shown here appears where the
incoming azimuth or bearing is
specified.
• Rect : will compute and store the
fourth and final point that forms a
rectangle or parallelogram after three
points are stored with a description associated with Rect.
Note: At any time, the line type for any linework command can be
changed while collecting linework for a particular feature. For
example, a feature called FENCE might primarily use the Line
linework command, but might also contain a curved section. To add a
curve to the fence, you would use the Ctrl-L Quick Pick to open the
Auto Linework screen and toggle Line to R-Crv prior to storing the
first point of the curve. Once the second point of the curve is stored,
the curve is defined and appended to the FENCE polyline. This
routine is enhanced with the Props command, described below.
; On : When checked, activates the associated linework command. If
a particular polyline is created and then this is unchecked for that
linework command, future points stored with the same description
would not result in any change to that polyline. But if this is then
activated again later, all future points collected using the same
linework command will be appended to the original polyline.
End: Toggles between the following two functions, giving you control
in collecting data for two or more separate features that use the same
linework command:
When the map icon is displayed for this button, a polyline has
been created for the associated linework command. Tapping the
button will then allow you to detach future points using this linework
command from the current polyline, resulting in future points being
added to a new polyline.
