You can create an extruded surface, which is a three-dimensional polygon mesh that approximates the surface generated by extruding a path curve along a direction vector. You select the two entities that define the path curve and direction vector. The length of the direction vector determines the distance the path curve is moved along the direction vector. The extruded entity can be an arc, circle, line, or polyline. You can choose a line or open polyline as the direction vector. The resulting mesh consists of a series of parallel polygonal planes running along the specified path.

TIP To control the density of the mesh, change the values for the Number Of M-Direction Surfaces. Choose Settings > Drawing Settings, and then click the 3D Settings tab. Under Change Settings For, select Surfaces. Under Surface Settings, change the Number Of M-Direction Surfaces. Or, on the Settings toolbar, use the Drawing Settings tool () to display that dialog box.
