Unit 3: Introduction to Inventor user interface and sketching environment

About This Unit

This unit introduces Autodesk Inventor Professional software. The software is a parametric solidmodeler that provides you with design tools that focus on the entire product development

process.

After completing this unit, you will be able to:

■ Identify the main components of the Autodesk Inventor user interface.

■ Use the ine tool to create sketches with lines and tangencies.

■ Use the !onstraint tool to add and display geometric constraints.

■ Use the "imension tool to add dimensions and si#e a sketch.

■ Use the $easure tools to measure the length of lines and the distance between points.

The draw tools in Autodesk Inventor

%ou review various software applications as you progress through the design process.

In addition to these learning materials, we also recommend you to check Inventor interactive tutorials. %ou can find them at

the et (tarted screen.
