Problems with Earlier Technology

Wireframe ambiguity Points and lines only No surfaces 2D trying to look 3D Perspective points

Non-Realizable Object Surface definition

Concurrent Engineering

Feature based parametric modeling Flexible in Design Changes made easily with little or no cost Faster due to visualization No models or prototypes necessary

Parametric The Geometric definition of the design

can be varied at any time during the design process.

A part is a sequence of engineering features, which can be modified/ changed at any time.

Concentrate on original design intent

Parametric Modeling Benefits Begin with simple conceptual models with minimal detail “shape before

size” Geometric relations, dimensional constraints, and relational parametric

equations can be used to capture design intent Ability to update entire system, including parts, assemblies, and

drawings after changing one parameter in one place Quickly explore and evaluate different design variations and alternatives

to determine best design. Existing data can be used to create new designs Quick design turn around.

Starting Solid Works Menu Bar Resources Icon- task pane, design library, file explorer Start up Options- if not there click on resources icon Task Pane- to close click in main area Option to pin open with pin in upper corner Tutorials

Starting a new part Click on new part from either the menu bar or task pane. Choice of part, assembly, or drawing ALWAYS start by setting up the units you want to use under the options

icon on the menu bar Should be default of IPS (Inch, pounds, seconds) Set Precision

Parametric Modeling Fundamentals

SOLID WORKS CHAPTER 2

Creating Rough Sketches ZEN approach (forget what you have learned) Create a sketch that is proportional to the desired shape

Concentrate on shapes and forms Keep the sketch simple

Leave out small features Fillets Rounds Chamfers

Exaggerate the geometric features of the desired shape If angle is 85˚ create at 60˚ so solid works doesn’t assume it

is 90˚ angle Draw the geometry so it doesn’t overlap

Self intersecting Form a closed region

Act as if water was inside

Parametric Modeling Steps Create rough two dimensional sketch of the basic shape of

the base feature of the design Apply/ Modify geometric relations and dimensions to the

two dimensional sketch Extrude, revolve, or sweep the parametric two

dimensional sketch to create the base solid feature of the design

Add additional parametric features by identifying feature relations and complete the design

Perform analyses on the computer model and refine the design as needed.

Create the desired drawing views to document the design

Sketch Plane 3D objects are located and defined in World

Space or Global Space Based on Cartesian Coordinate System Front Plane XY Top Plane XZ Right Plane YZ Cannot be changed or Manipulated

Local Coordinate System- relative to World Coordinate System Can be changed and manipulated

Solid Works Homework AssignmentsPrint screen should look similar to this with your name on the top left corner under a comment showing a timestamp of where the work was done and when. It should be printed on a letter sized sheet of paper.
