Large projects

To get the most out of your time and machine performance, we have created an overview of best practices when working in large Gemini Terrain projects.

Large application layers

If you are working with large application layers, especially when they contain large triangulation networks with elongated extensions, performance can be improved by following the tips below:

  1. Split the large application layers into several smaller ones, preferably in a grid pattern.
    This will reduce loading time and update time in the view.

  2. If you do not want to split into multiple application layers, split the triangulation networks into several small triangulation networks.
    This will reduce update time and calculation time for the terrain.

  3. If the triangulation networks do not have overhangs, and it is possible to calculate a boundary contour: Use presentation rule for area filling in 2D.
    This will reduce update time, as well as reduce the size of plots. This is also useful for working in 3D Field.

  4. Optionally set a simple hatching as the presentation rule for triangulation networks.

Elongated road projects

If you are working in elongated road projects and are calculating and editing a small part such as a construction pit or a small road section, you can clip against the terrain model area. This will reduce update time, and thus also recalculation time.

Procedure

  1. Set up a terrain model area that barely covers the object you are working with.
  2. Turn on clipping against the terrain model area in both 2D and 3D.

Application layers with presentation rules

If you are working with application layers with many presentation rules and only need to see the geometry, you can improve performance by reducing the detail level for faster viewing when you don't need to see all details:

Instructions

  1. Go to Drawing Settings
  2. Turn off High detail level

Elongated road projects with a lot of text

If you are working with long road projects with a lot of text, the performance in 3D can be improved by:

Procedure

  1. Open Rendering Settings on the Render toolbar (in 3D view).
  2. Check Use simplified font (lower quality) in the OpenGL display settings tab.
