Three-dimensional modeling tools range from entering precise measurements in the Properties palette, to more free-form methods such as grip and gizmo editing. Some methods are specific to 3D solids or meshes. Other methods are shared.

Convert to Other Object Types

In many cases, you can convert from one object type to another to take advantage of specific editing capabilities.

For example you can convert selected surfaces, solids, and legacy mesh types to mesh objects so that you can take advantage of smoothing and modeling capabilities.

Similarly, you can convert mesh to 3D solids and surfaces to accomplish some composite object modeling tasks that are available only for those objects. Conversion is often offered as a choice when you start activities that are available only for solids and surfaces.

View Your Model from All Angles

When you work with any 3D object, you can easily make changes that are not accurately reflected in the current view. To ensure that your modifications conform to your expectations, make sure you understand and use the following:

Manipulate the 3D workplane (UCS). To understand how your model is projected in 3D space, learn how to use the X, Y, and Z axes. See Specify Workplanes in 3D (UCS).
Rotate the view to display the model from different viewpoints. Several navigation tools, including 3D Orbit and the ViewCube, are available to help you rotate around your workspace. See Use Viewing Tools.
Display multiple viewports. Set up two or more viewports with different viewing angles and visual styles. When you make a change in one viewport, you can see its impact from several viewpoints at the same time. See Display Multiple Views in Model Space.
