• 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

• 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
