Overview of Modifying Faces on 3D Solids
You can edit your solid object by extruding, moving, rotating, offsetting, tapering, deleting, or copying it, or by changing the color of the faces.
You can select individual faces on a 3D solid object or use one of the following AutoCAD selection methods:
Boundary set
Crossing polygon
Crossing window
Fence
Boundary sets are sets of faces defined by a closed boundary, which consists of lines, circles, arcs, elliptical arcs, and spline curves. When defining a boundary set on a solid object, you first select an internal point on the solid, highlighting the face. If you select the same point on the face again, AutoCAD highlights the adjoining face.
You can also select individual faces or edges with your pointing device or use a crossing window, an irregular shaped polygon, or a fence that selects faces or edges that it passes through.
Extrude Faces on 3D Solids
You can extrude planar faces of a 3D solid along a path, or you can specify a height value and a tapered angle.
You can extrude planar faces along a path, or you can specify a height value and a tapered angle. Each face has a positive side, which is the side in the direction of the face's normal (the current face you're working on). Entering a positive value extrudes the face in its positive direction (usually outward); a negative value extrudes in the negative direction (usually inward).
Tapering the selected face with a positive angle tapers the face inward, and a negative angle tapers the face outward. The default angle, 0, extrudes the face perpendicular to its plane. If you specify a large taper angle or a long extrusion height, you can cause the face to taper to a point before it reaches the extrusion height; AutoCAD rejects the extrusion. Face extrusion along a path is based on a path curve (lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines).
You can also extrude the face of a solid object along the path of a specified line or curve. All profiles of the selected face extrude along the chosen path to create the extrusion. You can select lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines as paths. The path should not lie on the same plane as the selected face or have areas of high curvature.
