Terrain Overview
Create a ground surface, shape proposed changes and inspect the result with terrain analysis.
Terrain OverviewTerrain combines an existing ground surface with proposed changes. Import measured data or create a starting surface, then shape it with points, brushes or grading objects. Analysis is calculated from the available model; a detailed-looking surface does not establish the accuracy of its source survey.
Open terrain editing
Open the Terrain workspace. The left rail offers Data, Model and Analyze. The right panel includes Tool Guide, Inspector and Outliner. Select a tool to see its instructions, or select an existing terrain object to edit its properties.
Create or import the ground
Use Data to import terrain or create it from scratch. Check its physical dimensions, elevation units and position. Replacing a ground surface is different from adding a proposed grading object; read any replacement confirmation.
Shape the proposal
Use Model for Volume Points, Spray Sculpt, Pad, Sloped Pad, Retaining Wall, Breakline, Grade Limits, Drainage and the offered grading tools. Tools that draw a line or polygon become editable objects after completion. The Model button remembers the last chosen tool; its arrow opens the choices.
Inspect the result
Use the top-bar Display menu to toggle Contours, Slope, Aspect and Runoff. Analyze offers Profile, Region, Slope and Cut/Fill. Existing, Proposed and Compare surface views help distinguish the baseline from the design.
Keep editing or leave
Use Undo and Redo for recorded changes. Use Close to leave the workspace. Terrain and proposed objects remain part of the project; closing is not a separate Apply operation.
