The Alignment Manager in VisionLidar enables users to create, modify, delete, and analyze horizontal alignments within the Vision database. Alignments are crucial for sections, profiles, road modeling, and camera paths.

1. Overview of Alignment Manager

The Alignment Manager interface consists of:

✔ Left Panel – Displays all created alignments.
✔ Center Panel (Optional: "Calculation on Alignment") – Computes offsets and distances along alignments.
✔ Right Panel – Used to define and manage the selected alignment.
✔ "Raw Align." Tab – Lists the points of intersection (PI) making up the alignment.
✔ "Horizontal Alignment" Tab – Displays individual segments of the alignment.

💡 Alignments created in this tool are exclusively horizontal alignments. Vertical alignments must be managed in the Civil Module.

2. Available Functions in Alignment Manager

Computation & Modification

✔ Compute Distance/Offset – Calculates the distance of a point along the alignment and its offset.
✔ Compute Point(s) – Generates a point at a specific distance & offset.

  • By Interval Option – Creates multiple points at regular intervals along the alignment.
    ✔ Compute Offset – Draws left and right offset alignments with user-defined values.

Alignment Management

✔ Save – Saves any changes made to the alignment.
✔ Validate Points – Checks if there are existing points at the alignment vertices.
✔ Create Points – Generates new points at alignment vertices that lack points.
✔ Report – Produces a text report detailing the alignment’s geometry and structure.
✔ Invert – Reverses the order of alignment points.
✔ Reinitialize – Deletes the alignment definition while keeping the points in the database.
✔ Import/Export LandXML – Imports and exports alignments in LandXML format for CAD & civil engineering software.

Picking Points & Drawing Alignments

✔ Pick Points – Adds alignment points by manually picking them in the drawing.
✔ Pick Polyline – Converts a polyline into an alignment, creating temporary points at each vertex.

  • Validate Points Option – Matches existing points to polyline vertices.

  • Create Points Option – Generates new points at polyline vertices.
    ✔ Draw/Erase Alignment – Displays or removes the alignment in the drawing view.

 

 

3. Understanding Horizontal Alignments

✔ Raw Alignment Tab – Shows tangent intersections used in alignment construction.
✔ Horizontal Alignment Tab – Lists all alignment segments, which can be:

  • Lines

  • Curves

  • Spirals

  • Spiral-Curve-Spiral combinations

💡 For advanced vertical alignments (road grading, elevation profiles), refer to Civil Module – Alignment Section.

4. Key Benefits of the Alignment Manager

✔ Versatile Application – Used in road design, railways, and land development.
✔ Comprehensive Control – Modify offsets, distances, and geometry with precision.
✔ Flexible Input Methods – Define alignments using points, polylines, or LandXML imports.
✔ Seamless Integration – Works with sections, profiles, camera paths, and corridor modeling.
✔ Export-Ready – Share alignments in LandXML format for use in BIM, CAD, and GIS platforms.

🚀 Define and Optimize Alignments for Infrastructure & Surveying!

With the Alignment Manager, users can accurately create, edit, and analyze alignments, ensuring seamless integration with road modeling, profiles, and survey workflows. 📍🛣️
