Edit Model

Used to edit a terrain model that has no graphic elements with rules and includes manipulating vertices, swapping lines, and deleting triangles.

You can access this tool from the following:

Ribbon: Terrain > Edit > Edit Model

These editing commands are for a terrain model that has no graphic elements with rules. For example, importing terrain models from other formats without creating features. The commands allow limited editing without returning to the source and importing features. If you need additional editing capabilities then import the original source and use the other editing methods.

These commands can control the maximum length of the triangles and allows editing of the triangle. It can keep a track of edits from the survey data.

Settings	Description
Delete Vertex	Deletes the specified vertex, then re-triangulates the terrain model without it. Note you cannot select a vertex that is on the edge of the terrain model (boundary).
Delete Edge Triangle	Determines the triangle from the user-defined edge, then deletes the triangle from the model and the boundary is updated accordingly.
Swap Line	Changes the common side of two triangles.
Insert Vertex	Inserts a vertex inside or outside of the terrain model. If the point is inside the model, an option is supported to use the elevation of the face (interpolated from the triangle vertices) as the elevation.
Move Vertex	Moves the vertex of a triangle. A toggle in the tool settings enables the user to use the elevation of the original vertex.
Delete Triangles by Line	Deletes all triangles which intersect the line (defined by two data points within the tool) and the boundary is updated accordingly.
Delete Feature	Delete feature tool removes the selected feature from the terrain model.
Delete Edit	This option will reverse the Terrain Model edits to the original state by picking the glyphs assigned to each edit (white lines or dots). A terrain model from Survey can remain ruled and still be edited with Delete Triangle by Line or any other command, if the user deletes a spot, delete triangles, and so on, and reprocess or edit the survey, the edits will remain. You can use the Delete Edit option to reverse the edits.
