Input

• 1 or more groups containing one well-defined perimeter.
• 1 or more groups containing an open edgepath.
• 1 raw open edgepath.

Operation

Direct

1. Pre-select valid input, per above.
2. Run Command.
3. To adjust result, type values.

Command is a Pick command.

Parameters

• Down slope
• Up Slope
• Distance
• Direction

Express Slope in Percent

Flare controls slope by expressing a percentage. This percentage is calculated as the ratio between rise and run. Rise is the difference in height. Run is the difference in plan.

A rise of 1 and a run of 1 yield a Slope of 100 % or 45 degrees.

A rise of 1 and a run of 4 yield a Slope of 25 % or roughly 12 degrees.

Direction

You may Blend outwards, inwards, or both directions.

• To flip Blend direction, use key Arrow up.
• To Blend outwards, use key Arrow right.
• To Blend inwards, use key Arrow left.
• To Blend symmetrically, use key Arrow down.

Read the Status Bar

The status bar will show current options. Directions refer to keyboard Arrow keys.

Feel the Flare

Put a grouped level rectangle in the middle of a big dramatically sloping terrain plot, so it partly sticks into the slope.

Select the rectangle, and Run Fit. Now, run Flare.

To explore what Flare does, experiment with the four parameters in the VCB. Start with low-percent Slopes, a long length, and Direction 1.

What does the Direction Parameter Mean?

It controls whether to move terrain upwards-and-downwards, downwards-only, or upwards-only. Also see the Panel..

Outwards or Inwards?

If you blend an closed path, for instance a circle, what is outwards is clear. Now, if you remove one segment from the circle, it is still quite clear what is outwards, even though it is now a an open path.

If you blend an open path, Landshape will try to determine what is outwards and inwards by the convexity of the path.

If you blend a single straight path (which lacks a convex/concave distinction), Landshape will interpret outward as towards the camera.
