Create Point Slope to a LANDSurface

Point Slope to LANDSurface

The Create Point Slope to LANDSurface tool enables you to simulate where a projected line with a defined fall gradient and specified direction would meet an existing LANDSurface.

Two Point Slopes (red) visualizing where projected lines would meet an existing LANDSurface. Green crosses represent Spot Levels.

Create Point Slope

To use the Create Point Slope to LANDSurface tool:

  1. Select an existing LANDSurface.
  2. Select parent Spot Level (not part of the LANDSurface).
  3. Go to:
    • LAND4/Group Palettes/Show Spot Level Palette, or
    • LAND4 Palette/Spot Levels.
  4. Press Create Point Slope to LANDSurface button.
  1. Enter fall percentage in Fall Palette (negative values = elevation).
  2. Define fall direction using Rubber Band line. 

A new, interpolated child Spot Level will now automatically be created at the intersection point of the (projected) rubber band line and selected LANDSurface.

LANDSurface missed

Should the rubber band line miss the LANDSurface, a warning pops up.


Dependencies

The new interpolated Spot Level is a child of the parent Spot Level and the selected LANDSurface. All three objects are dynamic objects holding dynamic relations to one another.

If the parent Spot Level is moved, elevated, or otherwise updated, then the child Spot Levels position will be updated accordingly.

Arrows on dependency lines always point from children Spot Levels towards parent Spot Levels, and here they point towards the corners of the specific LANDSurface triangle the Point Slope hits.
