What is TIN Civil 3D?

TIN stands for triangulated irregular network. This kind of surface is made up of non-overlapping triangles. Each of the triangles represents a face on the surface.

How do you make a TIN surface from contours in Civil 3D?

You can add contour data to an existing TIN surface.

…

To Add Contour Data to a Surface

1. In Toolspace, on the Prospector tab, expand the surface Definition collection, right-click Contours, and click Add.
2. In the Add Contour Data dialog box, enter the contour description in the Description field.

What is TIN surface?

A triangulated irregular network (TIN) is a representation of a continuous surface consisting entirely of triangular facets (a triangle mesh), used mainly as Discrete Global Grid in primary elevation modeling.

What kinds of data can you use to create TINs?

You can create a TIN surface from features, such as points, line, and polygons, that contain elevation information. Use points as spot locations of elevation data. Use lines with height information to enforce natural features, such as lakes, streams, ridges, and valleys.

What is a TIN file?

Triangular irregular networks (TIN) have been used by the GIS community for many years and are a digital means to represent surface morphology. TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points).

How do I import a surface into Civil 3D?

Solution:

1. In the Toolspace / Prospector, select the surface.
2. Right click on the surface and select export Landxml (alternatively use the LANDXMLOUT command)
3. In a new drawing, import Landxml (alternatively use the LANDXMLIN command)

Is TIN a 3D?

TIN Faces. The connected 3D points that make up the TIN are TIN edges. They should not be looked at as lines but instead as a visual representation of the edge of the flat triangle.

What is the difference between DEM and TIN?

A DEM represents a regular array of elevation points. It can be converted to an elevation raster by placing each elevation point at the center of a cell. A TIN approximates the land surface with a series of nonoverlapping triangles.

What is a grid surface Civil 3D?

A grid surface comprises points that lie on a regular grid. You can create a grid surface or import it from a DEM file. Use grid surfaces for: Mapping more uniform surfaces with evenly distributed sample data. Examining large study areas (small-scale maps)
