Getting Started with Smart Slope Generator... 

Installation & Setup

1. Run Installer: After downloading, run the .msi file. It automatically detects Autodesk® AutoCAD® Verticals and Autodesk® Civil 3D® (2025/2026) versions.
2. Directory: Files are placed in the secure ApplicationPlugins folder.
3. Ribbon Access: Upon launching, look for the "Add-ins" Ribbon Tab (integrated for a cleaner workspace).

Step-by-Step Workflow:

1. Launching the Command

• Via Ribbon: Navigate to the Add-ins tab and click the DRAWSLOPE icon.
• Via Command Line: Simply type DRAWSLOPE and press Enter.

2. Configuring Parameters (Interactive Dialog)

The new dialog features a Live Preview Canvas that reflects changes instantly. Adjust these settings:

• Step: Defines pattern density (distance between lines).
• Ratio: Controls the length of shorter intermediate lines (e.g., 50%).
• Offset: Sets the gap between the pattern ends and the boundary lines.
• Layer & Color: Select an existing layer or create a new one directly from the UI. 

3. Choosing the Generation Method

• Elastic (Default): The most advanced method. It proportionally distributes lines and allows for manual "fixing" of overlapping areas in complex turns.
• Perpendicular: Forces lines to be 90° to the Crest, ideal for structural walls.
• Hybrid: A smart mix that adapts to varying geometry.

4. Execution & Selection

Click the "Draw" button.

• Prompt 1: Select the Upper Curve (Crest).
• Prompt 2: Select the Lower Curve (Toe). 

Note: The tool supports 2D/3D Polylines and Civil 3D Feature Lines. Ensure "Is 3D" is checked in settings if elevation data is required.

Tips for Best Results

• Clean Geometry: For the best results with the Elastic method, ensure your polylines don't have self-intersections.
• Smart Memory: The plugin remembers your last-used settings (Step, Ratio, Color), so you don't have to re-configure for every new slope.
• F1 for Help: If you get stuck, simply press F1 while the command is active to open the detailed offline documentation.

Summary

1. Launch: Click Draw Slope in the Add-ins tab or type DRAWSLOPE.
2. Configure: Use the Live Preview to set your Step, Ratio, and Method.
3. Draw & Select: Click Draw, then select Crest, then Toe.
4. Finish: Press Enter to finalize. Your pattern is created as lightweight, standard AutoCAD objects.

Installation: Run the downloaded .msi file. The installer will automatically detect your Autodesk products and install the plugin in the correct directory.

Uninstallation: You can unload the plugin by exiting the Autodesk product and running the installer again (selecting "Remove"), or by using the Windows Control Panel > Programs and Features.

Background Hatching: While the slope lines are generated accurately using the projection algorithm, the optional "Background Hatch" feature may occasionally require manual adjustment. In scenarios with complex or self-intersecting geometry, the hatch might not fill the area completely or may spill outside boundaries. Users may need to adjust the hatch boundaries manually in these specific cases.
