Solid Editing Command entry: solidedit Solids editing automatic checking: SOLIDCHECK=current Enter a solids editing option [Face/Edge/Body/Undo/eXit] <eXit>: Enter an option or press ENTER Face Edits 3D solid faces by extruding, moving, rotating, offsetting, tapering, deleting, copying, or changing the color of the selected faces. Enter a face editing option [Extrude/Move/Rotate/Offset/Taper/Delete/Copy/coLor/mAterial/Undo/eXit] <eXit>: Enter an option or press ENTER Extrude Extrudes selected planar faces of a 3D solid object to a specified height or along a path. You can select multiple faces at one time. Select faces or [Undo/Remove]: Select one or more faces or enter an option Select faces or [Undo/Remove/ALL]: Select one or more faces or enter an option Undo Cancels the selection of the faces you added most recently to the selection set and redisplays the prompt. If all faces have been removed, the following prompt is displayed. Face selection has been completely undone Remove Removes previously selected faces from the selection set. The following prompt is displayed. Remove faces or [Undo/Add/ALL]: Select one or more faces (1), enter an option, or press ENTER Undo Cancels the selection of the faces you removed most recently from the selection set and redisplays the prompt. If no faces are currently selected, the following prompt is displayed. Face selection has been completely undone

Add Adds faces to the selection set. Select faces or [Undo/Remove/ALL]: Select one or more faces (1) or select an option

 Undo: Cancels selection of the faces you added most recently to the selection set and redisplays the prompt.  Remove: Removes previously selected faces and redisplays the prompt. All

 All: Selects all faces and adds them to the selection set and redisplays the prompt. Selects all faces and adds them to the selection set.

All Selects all faces and adds them to the selection set. After you select faces or choose an option, the following prompt is displayed. Select faces or [Undo/Remove/ALL]: Select one or more faces (1), enter an option, or press ENTER

Specify height of extrusion or [Path]: Specify a distance or enter p

Height of Extrusion Sets the direction and height of the extrusion. Entering a positive value extrudes the face in the direction of its normal. Entering a negative value extrudes the face in the direction opposite to its normal. Specify angle of taper for extrusion <0>: Specify an angle between -90 and +90 degrees or press ENTER

Tapering the selected face with a positive angle tapers the face in, and a negative angle tapers the face out. The default angle, 0, extrudes the face perpendicular to its plane. All selected faces in the selection set are tapered to the same value. If you specify a large taper angle or height, you can cause the face to taper to a point before it reaches the extrusion height. Path Sets a path for the extrusion path based on a specified line or curve. All the profiles of the selected face are extruded along the chosen path to create the extrusion. Select extrusion path: Use an object selection method

Lines, circles, arcs, ellipses, elliptical arcs, polylines, or splines can be paths. The path should not lie on the same plane as the face, nor should it have areas of high curvature. The extruded face starts from the plane of the profile and ends on a plane perpendicular to the path at the path's endpoint. One of the endpoints of the path should be on the plane of the profile; if not, the path is moved to the center of the profile. If the path is a spline, the path should be perpendicular to the plane of the profile and at one of the endpoints of the path. If not, the profile is rotated to be perpendicular to the spline path. If one of the endpoints of the spline is on the plane of the face, the face is rotated about the point; otherwise, the spline path is moved to the center of the profile and the profiles are rotated about its center. If the path contains segments that are not tangent, the object is extruded along each segment and then the joint along the plane is mitered, bisecting the angle formed by the segments. If the path is closed, the profile lies on the miter plane. This allows the start and end sections of the solid to match up. If the profile is not on the miter plane, the path is rotated until it is on the miter plane. Move Moves the selected face on a 3D solid object to a specified height or distance. You can select multiple faces at one time. Select faces or [Undo/Remove]: Select one or more faces or enter an option The descriptions of the Undo, Remove, Add, and All options match the descriptions of the corresponding options under Extrude. After you select faces or enter an option, the following prompt is displayed. Select faces or [Undo/Remove/ALL]: Select one or more faces (1), enter an option, or press ENTER Specify a base point or displacement: Specify a base point (2) Specify a second point of displacement: Specify a point (3) or press ENTER

The two points you specify define a displacement vector that indicates how far the selected face is moved and in what direction. SOLIDEDIT uses the first point as a base point and places a single copy relative to the base point. If you specify a single point, usually entered as a coordinate, and then press ENTER, the coordinate is used as the new location. Rotate Rotates one or more faces or a collection of features on a solid about a specified axis.
