~~DISCUSSION~~ ~~REVEAL~~ ====== Phone Case Workshop 02 ====== ===== Proposal ===== This Workshop builds upon [[workshops:prototypes:try_its:phonecase:start|Parametric Phone Case]] to construct a prototype parametric phone case using the laser cutter. ===== Activity Summary ===== We will measure then model our phones, then use that model to create a case based upon a pre-existing model. We will choose material from The Edge's fabrication Lab store to explore the limitations and strengths of laser-cutting a 3D object in acrylic and plywood. ==== Fusion360 ==== The functions of Fusion360 to be demonstrated are; * Creating sketches on a face * Changing Parameters * Adding Dimensions * Mirror in sketches * Mirror bodies * Pattern bodies on a path * Selection Sets * Combine Bodies * Export DXF ==== CorelDraw and Laser Cutting ==== Using CorelDraw and the RayJet300 we will * Align Objects for cutting * Create engraved text * Cut case parts ==== Materials ==== These materials are per participant if not specified otherwise. * {{ :workshops:try_its:phonecase02:parametricphonecasemodel.f3d |parametric phone case model}} * phone to measure * 200mm x 200mm of approved material to cut (acrylic or ply) ===== Tools ===== ==== Digital ==== * fusion360 with a working user account per participant * CorelDraw and laser-cutter PC ==== Analog ==== * Precision Caliper * superglue * acrylic glue * sidecutters * cutting/gluing board ===== Outline:Part One ===== ==== Step Zero: Getting Started ==== Lets get set-up for the workshop. If you are in the Fabrication Lab, * grab a laptop * log on as edgeuser * launch Fusion360 (and log on using the account you created in workshop 01) * download the {{ :workshops:try_its:phonecase02:parametricphonecasemodel.f3d |phone case model}} ==== Step One: Recap ==== Its time to remember the basics of fusion360. In your new blank model - see if you can: * Create a sketch on the bottom plan (XZ) * draw a rectangle with the centre on the origin * break some constraints * Make some constraints * create a parameter * Dimension a line or point ==== Step Two: Measuring Phones ==== Time to take a good look at your phone and measure; * length * width * height * curve radius or slope * fillets * screen inset * button insets * charger inset ==== Step Three: Choosing Materials ==== Lets discuss and choose the materials we can use to make our prototype, by examining the existing examples. * acrylic * ply * acrlyic + ply? What material do you want to use? ==== Step Four: A Parametric Tour Using the Design History ==== We will use the Design History explore the model. This allows us go step by step through the making of our model. Open the model using the 'new design from window' {{ :workshops:try_its:phonecase02:2016-11-01_15_51_35-autodesk_fusion_360.png?200 |}} ==== Phone : Design History ==== * In the Browser, hide all components except for the phone:1 (using the lightbulb button) * active the phone component * Make sure all sketches and bodies are visible * Drag the History Marker back to the start * Step through the history with the play button ==== Phone : Sketch ==== * Find the phoneDetails Sketch and right-click to edit * Show and hide the bodies * Drag the curve point around - notice the other line changes? * Click Show constraints Sketch Palette * What is the constraint making the lines move together? * Stop The Sketch * Exit the component by Clicking on your assembly name (the name of your model) * Click the home button to reset your viewpoint. * Drag your Model design history all the way to the right to reset it. ==== Spines : Design History ==== * In the Browser, hide all components except for the Spines:1 * active the spine:1 component * Make sure all sketches and bodies are visible * Drag the History Marker back to the start * Step through the history with the play button * Make sure you end up at the end of your component Design History ==== Spine : Sketches ==== * Find the phoneProfile Sketch and right-click to edit * Notice the spine drawn in construction lines off to the right. * Can you find the mirror constraints? * The offset constrain? * The parameters used in the sketches? * Stop the sketch ==== Spine : Body - Pattern on Path ==== * Make sure you end up at the end of your component Design History * Right Click the PathPattern1|Spines * CLick Edit Feature * Change to the front view * Change the Quantity and Path Direction to see how they affect your model. * Click the small tick boxes to suppress individual spines. * CLick OK or cancel to exit The Edit feature ==== Spine : Body - Mirror ==== This is a create function similar to the sketch functon 'mirror' * Make sure you end up at the end of your component Design History * Right Click the Mirror1|Spines * CLick Edit Feature * Deselect your object and mirror plane with the X * Re select your objects.. * and mirror plane * CLick OK or cancel to exit The Edit feature ==== Ends : Design History ==== * In the Browser, hide all components except for the ends:1 (using the lightbulb button) * active the ends component * Make sure all sketches and bodies are visible * Drag the History Marker back to the start * Step through the history with the play button ==== Ends : Sketches ==== * Find the end Sketch and right-click to edit * Its a simple sketch with only one constraint... * Stop the sketch ==== Ends : Body Extrude ==== This is how we make a combined body - first we extrude.. * Make sure you end up at the end of your component Design History * Right Click the Extrude1|ends * CLick Edit Feature * Notice the Distance parameter * CLick OK or cancel to exit The Edit feature ==== Ends : Body - Combine ==== * Make sure you end up at the end of your component Design History * Right Click the Combine1|ends * CLick Edit Feature * Make your spines visible * Now we can see our target body - in blue * and our tools bodies in red - these will cut into our target. ====== Break Time ====== =====Outline:Part Two ===== ==== Step Five: Troubleshooting ==== ==== Step Six: References ==== ==== TryIt and Feedback ==== 1. __Feedback__: __Solution__: 2. __Feedback__: __Solution__: 3. __Feedback__: __Solution__: 4. __Other observations__: ==== References ==== ==== Msic Files ==== These are files used to develop the workshop, test cuttings, experiments, failures, etc..... {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:phonecaseworkshopbalnk.zip |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:workshop02testblank2.zip |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:trophy_1.cdr |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:ribcasev1.zip |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:ribcasev2.zip |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:ribcasev4.zip |}} {{ workshops:prototypes:2022-23delivery-lasercutcovers:phonecase02:ribcasev5.zip |}}
