Carlson Precision3D 2023 Video 13 - Pad Template Slope Work

Tutorial: Improving DTM for Precise Flow Calculations using Pad Template Slope Work

Step 1: Setting up a 10 Edge Snap

1. Open your Carlson Precision3D 2023 software.
2. Navigate to the DTM (Digital Terrain Model) module.
3. Focus on improving the DTM for more precise flow calculations.
4. Understand the concept of setting up a 10 Edge Snap for accurate measurements.

Step 2: Creating a Polyline with 10 Edges

1. Select the Polyline command in the software.
2. Click on 10 different edges along the road to create a precise polyline.
3. Start from one edge and continue selecting edges until you reach the upper corner.
4. Press 'C' to close the polyline shape.

Step 3: Reviewing and Adjusting Vertices

1. After creating the polyline, select it to view its properties.
2. Turn off the snap feature if it's enabled.
3. Review the vertices of the polyline to see the segments and their elevations.
4. Note the elevations of the vertices for further adjustments.

Step 4: Using Pad Template Slope Work

1. Right-click and access the Topo command in the software.
2. Choose the Pad Template option with the default single elevation setting.
3. Ensure that the software follows the actual vertices' elevations for accuracy.
4. Adjust any vertices that are slightly higher to maintain the correct slope.

Step 5: Merging Surfaces and Updating DTM

1. Let the software merge the surfaces to create a smooth transition.
2. Observe the updated DTM and the eliminated wall in the design.
3. Add material shoulders to enhance the surface appearance.

Step 6: Drawing Additional Polylines

1. Deselect all existing polylines in the design.
2. Use the TIN snap feature to draw another polyline accurately.
3. Utilize the endpoint snap to ensure precise endpoint connections.
4. Close the polyline shape by pressing 'C'.

Step 7: Applying Materials and Runoff Coefficient

1. Highlight the new polyline (Polyline 3) in the design.
2. Access the materials library in the software.
3. Drag and drop a grass material onto the polyline to simulate ground cover.
4. Verify that the grass material has a runoff coefficient of 0.2 for proper water drainage.

Step 8: Finalizing the Task

1. Review the changes made to the DTM and surface design.
2. Ensure that the runoff coefficient meets the requirements for accurate calculations.
3. Congratulations! You have successfully accomplished the task of improving the DTM for precise flow calculations using Pad Template Slope Work in Carlson Precision3D 2023.

By following these steps, you can enhance the accuracy and visual representation of your terrain modeling projects using the features provided in the Carlson Precision3D 2023 software.
