•  SolidWorks is a powerful CAD modeling tool:

•  Parametrically driven design automation software

•  Can be used to create simple and complex parts and assemblies

•  Can also be used for engineering analysis

•  Rapid prototyping

•  3D printing

•  Has bioengineering applications

•  SolidWorks format:

•  Linear in construction: sketch à dimension/relations à feature

•  Based on the creation of a feature

•  Base feature, sketched features, applied features

•  Defining a feature involves applying parameters

•  Design intent

•  Understanding how to read a drawing

•  Basics of sketching

Sketching: Establishing Relations

4  

•  In SolidWorks, relations between sketch entities and model geometry are an

important means of building in design intent

•  You can add relations in the following way:

•  As you sketch, allow the SolidWorks application to automatically add relations

•  Manually add relations using the “add relations” tool, or edit existing relations

using the “display/delete” relations tool

•  You can also mirror sketches, as well as apply linear and revolved patterns to your

entities

Building a Feature – The Second Step

9  

•  Ensure that your sketch is fully defined!

•  Once this is accomplished we can now progress to adding the third dimension

to our sketch, allowing us to come closer to our finished part

•  Bear in mind: other than planes, you can also sketch on the face of a feature,

providing that it is not curved (note: there are ways around this)

•  Always try to maintain design intent in every sketched/applied feature you

create on your base feature

•  After sketching, one of the most common features is an extruded “cut” and/or an

extruded “boss/base”

•  Will comprise ~90% of the features you use to form a part/assembly

Building a Feature – The Second Step

10  

•  After clicking extruded cut/boss/base:

•  Extrusion options:

•  From – starting plane

•  To – end condition

•  Thin feature

•  Draft

Complete the parts above after finishing the “30 Minute Tutorial”:

•  Make sure to pay attention to any “views” that are given (this will orient your part)

•  Only ONE extruded boss, and ONE extruded cut are necessary to complete all

three of these parts
