Aims and Objectives

The aim of this tutorial is to let you practice solid modeling by sketching, resolving a sketch, constraining a profile, revolving a profile to a solid, and place tapped hole. After studying this tutorial, you should be able to:

• construct a sketch,
• resolve a sketch,
• apply geometric constraints to a profile,
• add parametric dimensions to a profile,
• revolve a profile to a solid, and
• place tapped hole feature.

Basically, a solid is derived from a rough sketch. Prior using the sketch for making a solid, you have to fully constrain it by adding geometric constraints and parametric dimensions. To make a revolve solid, you can revolve a fully constrained profile. 

Modeling

Start a new single part drawing.

Use the LAYER command to construct two additional layers, Solid and Wire. Then set layer Wire as the current layer.

<Assist> <Format> <Layer...>

New layers: Solid and Wire
Current layer: Wire

Use the LIMITS command to set the drawing limits. Then use the ZOOM command to zoom to extents.

Key Points

In this tutorial, you constructed a sketch, resolved it to a profile, revolved the profile to a solid, and placed a tapped hole.
