How to Use the Spline Command in Map 3D

GIS applications such as AutoCAD Map3D construct contemporary maps.

Autodesk's AutoCAD Map3D is a computer-aided design application for planning and design at the scale of the city. The application draws traditional AutoCAD DWG files, but AutoCAD Map3D also develops geographic information system data and maps. GIS is very similar to CAD formats, but GIS is superior for documenting large land areas with many variables or sets of data. Use the "Spline" command to draw curvilinear lines that do not contain arcs in AutoCAD Map 3D.

Instructions

1. Open AutoCAD Map 3D. Select "New" in the "File" menu to create a new drawing file.

2. Type "Spline" in the command line and click your mouse across the drawing to trace a curving, sinuous line. Press the "Enter" or "Return" key twice to complete the spline.

3. Click the spline to select it and adjust the handles to move the curving form of the spline. Splines are useful for drawing topographical contours, natural land and water features, quick approximations of roads and curvilinear structures.
