•

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 open
the Job | 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.

If the button is blank and the current job contains at least one

polyline, you will be prompted to select an existing polyline. Once
