Most AutoCAD geometric editing commands are dependent on the location and orientation of the UCS. There are a variety of ways to set the User Coordinate System using the UCS command. 1. Type UCS at the command prompt. Command: ucs Enter an option [New/Move/orthoGraphic/Prev/Restore/ Save/Del/Apply/?/World] : New Defines a new coordinate system by one of six methods: Origin, Z Axis, 3 Point, Object, Face, View X, Y, Z Origin Defines a new UCS by shifting the origin of the current UCS, leaving the direction of the X,Y, and Z axes unchanged. ZAxis Allows you to define a new origin. 3 Point Specifies a UCS by its origin and a point on the positive X and Y axes. Object Lets you define a new UCS by pointing at an object.

Open a drawing with 3D objects and display in a 3D view. or 2. Choose View, Hide. 3. Type HIDE at the command prompt. Command: hide AutoCAD 3D Tutorial - 37 - 5.7 Dynamic UCS You can use the dynamic UCS to create objects on a planar face of a 3D solid without manually changing the UCS orientation. During a command, the dynamic UCS temporarily aligns the XY plane of the UCS with a planar face of a 3D solid when you move the cursor over the face. 


When the dynamic UCS is active, specified points, and drawing tools, such as polar tracking and the grid, are all relative to the temporary UCS established by the dynamic UCS. 1. 1.

You can view your entire drawing or select one or more objects before starting the command. When 3DORBIT is active, the target of the view stays stationary and the camera location, or point of view, moves around the target. However, from the user's point of view, it appears as if the 3D model is turning as the mouse cursor is dragged. In this way, you can specify any view of the model. 1.

Command: dashboard AutoCAD 3D Tutorial - 66 - AutoCAD 3D – Chapter 8 3D Model Objects AutoCAD 3D Tutorial - 67 - 8.1 Wireframes A wireframe model is a skeletal description of a 3D object. There are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object. With AutoCAD you can create wireframe models by positioning 2D objects anywhere in 3D space. AutoCAD also provides some 3D wireframe objects, such as 3D polylines (that can only have a CONTINUOUS linetype) and splines. Because each object that makes up a wireframe model must be independently drawn and positioned, this type of modeling can be the most time-consuming. Wireframe lines in 3D AutoCAD 3D Tutorial - 68 - 8.2 Surfaces Surface modeling is more sophisticated than wireframe modeling in that it defines not only the edges of a 3D object, but also its surfaces. 

The AutoCAD surface modeler defines faceted surfaces using a polygonal mesh. Because the faces of the mesh are planar, the mesh can only approximate curved surfaces. AutoCAD 3D Tutorial - 69 - 8.3 Solids Solid modeling is the easiest type of 3D modeling to use. With the AutoCAD solid modeler, you can make 3D objects by creating basic 3D shapes: boxes, cones, cylinders, spheres, wedges, and tori (do- nuts). You can then combine these shapes to create more complex solids by joining or subtracting them or finding their intersecting (over- lapping) volume. You can also create solids by sweeping a 2D object along a path or revolving it about an axis. AutoCAD 3D Tutorial - 70 - AutoCAD 3D – Chapter 9 2D Solids and 3D Faces AutoCAD 3D Tutorial - 71 - 9.1 2D Solid Creates solid-filled triangles and quadrilaterals. 1. Type SOLID at the command prompt. Command: solid First point: P1 Second point: P2 Third point: P3 Fourth point: P4 Third point: enter AutoCAD 3D Tutorial - 72 - 9.2 3D Faces 3DFACE creates a three or four sided surface anywhere in 3D space. You can specify different Z coordinates for each corner point of a 3D face. 3DFACE differs from SOLID, which creates a three- or four-sided surface that is parallel to the current UCS and can be extruded. 1. Type 3DFACE at the command prompt. Command: 3dface First point: pick Second point: pick Third point: pick Fourth point: pick Third point: enter 3D Wireframe Lines 3D Face AutoCAD 3D Tutorial - 73 - 9.3 3D Face Invisible Edge With 3DFACE, you control which edges of a 3D face are visible, allowing accurate modeling of objects with holes. Entering i or invisible before the first point of an edge makes the edge invisible.Type 3DFACE at thecommand prompt. 1. Type 3DFACE at the command prompt. Command: 3Dface First point: P1 Second point: P2 Third point: i P3 Fourth point: P4 Third point: i P5 Fourth point: P6 Third point: P7 Fourth point: P8 Third point: enter NOTE: You must enter an “i” for invisible before the face is chosen.
