Creating a TIN

• What is Meridian Tapping and How Can It Help

There are several ways to obtain a starting TIN as the foundation of your model. These are:

• Create or import contour lines and use the Sandbox From Contours Tool to create a TIN.

• Import an image of a site plan or contour map and trace its contours with the Freehand Tool. Then, adjust the contours to their proper elevation and use the Sandbox From Contours Tool to create a TIN.

• Import a TIN using the SketchUp ArcGIS Plug-in available at www.http://www.sketchup.com/markets/gis.php. ArcGIS is an industry standard application suite or Geographic Information System for working with geographical information such as the location of buildings within a world-wide global coordinate system.

• Import a digital terrain model (DTM) file.

• Create sandbox (TIN) using the Sandbox From Scratch Tool.
