When to Use the Remove Edge Tool
- Remove triangles edges over areas where they don't accurately model the Elevation Terrain.
- For example, you don't need elevation information and contour lines that cross over houses, buildings, or in some cases bodies of water.
- A great way to prevent the TIN from crossing over these kinds of terrain objects is by utilizing the Keep Outside tool.
- For example, you don't need elevation information and contour lines that cross over houses, buildings, or in some cases bodies of water.
- When your survey items has a concave shape around the edges, the triangulated area leads to long unnecessary TIN segments along the project border.
- Large triangles that link to survey items over large distances are unnecessary as they do not accurately model the Elevation Terrain.
- They need to be removed manually with the Remove Edge tool to provide a clean surface model.
Tip and Tricks
- You can remove multiple triangle edges simultaneously by holding the Shift key and dragging a box across the area you want to remove triangle edges from.
- The Remove Edge function only works on one surface item at a time.
- If several surface items are selected, the Edit Surface button does not show up in the TOOLS for Surface tab.
- You can use the Keep Outside and Keep Inside tools to remove large areas from your created surface and help save time.
- In some cases, you may want to flip the edge of a triangle to better match the terrain, rather than delete it; see our Flip Edge article for more details.
