🟧 How to Add a Sloped Surface

Create a sloped obstruction surface (e.g., a ramp), adjust heights, and visualize ray-traced RF effects.

Step 1: Turn Off the Heatmap

  • Disabling it prevents unnecessary recalculations while drawing the surface.

🟧 Step 2: Add a Surface Type

  1. Open the Obstruction menu (or press O).

  2. Go to Surfaces → Add Surface Type.

    • Choose Material (e.g., Concrete).

    • Set Thickness (e.g., 6 inches).

  3. Click Add Type to create your surface template.

✏️ Step 3: Draw the Surface

  1. Select the new Surface Type.

  2. Choose a drawing tool (e.g., Rectangle).

  3. Draw the surface in the canvas.

📐 Step 4: Set Slope Heights (Blue & Red Points)

  • After drawing, two points appear: Blue and Red.

  • Drag to set heights:

    • Example: Blue = 0 ft, Red = 9 ft (ramp rising from blue to red).

🖊️ Step 5: Create the Surface

  • Click Create Surface to finalize.

🧭 Step 6: View in 3D

  • Switch to 3D View to see the sloped surface in context.

✅ Step 7: Turn On the Heatmap (Ray Tracing)

  • Re-enable the Heat Map to recalculate propagation with the new surface.

  • Check 3D View again to observe the decrease in received power where the ramp attenuates the signal.
