TopoLT - Complete List of Functions

TopoLT - Complete List of Functions

  • Direct Coordinate Drawing: Draws points directly from coordinate files, draws coordinates from total station, or sends coordinates from drawing directly to total station.
  • Point Label Optimization: Point labels can be optimized to prevent overlapping with other entities placed near the point.
  • Customizable Point Codes: Point codes are translated according to a codes interpretation file defined by the user.
  • Graphical Point Drawing: Points can be graphically drawn with or without elevations, interpolating elevations where needed.
  • Entity Point Introduction: Automatically introduce points for entities like lines, polylines, and arcs that don’t have points at margins.
  • Sightshot Points Calculation: Calculate coordinates of polar points, with the ability to import measurements from most total stations.
  • Measurement Import: Receive measurements from instruments through serial ports.
  • Point Selection and Code Modification: Select points based on code and modify point codes as needed.
  • Coordinate Extraction and Table Creation: Extract point coordinates from drawings and save them in various formats, including those defined by instruments (total stations) or user-defined formats. Create coordinate tables for selected points, including a separate table for station points.
  • 3D Terrain Modeling: Generate 3D models of terrain and contour lines, calculate volumes without restrictions (the volume obtained by intersecting a 3D surface with a plane or between two 3D surfaces of any grid form or triangles).
  • 3D Model Manipulation: Cut, join, and visualize entities from drawings in real-time 3D rendering. Save AVI movies with moving three-dimensional objects, save images, visualize 3ds files, attach textures to 3D objects, and achieve photo-realistic visualization of 3D models.
  • Raster Image Transformation: Transform raster images to match the coordinate system of the plan, including cutting and framing, with support for various formats and color adjustments.
  • Point Symbols Management: Insert, scale, rotate, or delete point symbols (blocks) based on point codes.
  • Automatic Linetypes Change: Linetypes can be changed automatically according to the codes interpretation file.
  • Area Detachment: Detach areas using common cadastral methods like parallel, perpendicular, proportional, through an obliged point, and with obliged opening.
  • Automatic Grid Drawing: Automatically draw grids.
  • Numbered Sheets Creation: Create numbered sheets to view or print plan by plan for chained plans.
  • Automatic Border and Title Block Drawing: Draw borders and title blocks automatically, considering the printable area and paper format.
  • Google Earth Integration: Draw polygons, paths, or points in Google Earth with the assistance of the TransLT library.
  • Coordinate Transformation: Transform coordinates of points using TransLT models.
  • Extensive Program Configuration: Configurable to cover a wide range of scenarios. Supports multiple languages and user translations.
