Use the sketch tools as you did for the initial shape to create a profile for a raised area (switch panel) on the top surface as shown on the right. You will now be looking directly onto the top face. This will re-open the sketch interface – click on the Look at icon and choose the top face You are now ready to add some more 3D features to the top face Tumble the model – (F4 and LH mouse button) Click on the top face – it should turn red to show that it has been selected – click on the Sketch icon at the top of the screen. This box allows you to control all aspects of the 3D extrusion Because you have only created one sketch – this will be the default Profile Also by default, Output is set to Solid Extents is set to Distance Join (add material) is highlighted Above workplane is highlighted Enter a height of 12mm Because the design is for a vacuum form casing, it will need a draft angle > click on the More tab and enter a Taper value of 6 Click OK Click F6 to go to an Isometric view and choose Extrude You will see the Extrude dialogue box You should now see the Part Feature panel at the LH side of the screen. To complete the sketching stage, RH click and choose Finish Sketch This will exit sketch mode and you are now ready to create a 3D feature. You should now have a smooth ‘kidney bean’ shape. To tidy up the sketch – RH click anywhere on the design screen > choose Create Constraint > Tangent Now click on each pair of curves in turn to create a tangent constraint between them. I may look a little odd at this stage – but don’t worry – RH mouse click and choose Done to complete the sketch.

Now use the Tangent arc tool to close the shape. This may take a bit of practice but you have a multiple undo tool at the top of the screen (or Ctrl Z) if it’s not quite right first time …! Use the Centre point arc tool to create the two arcs shown on the right. Use the General Dimension tool to make the line exactly 40mm long > click on the line with the LH mouse button held down and drag to create dimension > single click on the dimension to edit > click green tick to ‘action’ This line is going to provide a starting point for the construction of the curved outline. To create the 2D sketch Use the Line tool to draw a line approximately 40 mm long –(you will see dimensions appear at the bottom of the screen) Click once with the LH mouse button to start – twice to finish. There are several useful keyboard shortcuts in Inventor that are worth getting to know. Useful Keyboard Shortcuts : Manipulating and moving around the model are important when solid modeling. To do this go to File > New > select Standard.ipt > click OK The standard design pane should now appear ready for you to create your new part.

You are now ready to create a design for the ‘top casing’ To do this open Inventor > go to File > New > Projects > New This will open the Inventor project wizard – Now follow the step by step instructions to create a New Single User Project > in Project File change Name to ‘casing design’ > in Project (Workspace) Folder, browse to find your homespace > choose Make New Folder > create new folder named ‘casing design’ > OK You will now be back in the first dialogue box – the folder ‘casing design should now appear in your list of Inventor projects > click Apply > Done All the work you do on the casing design project will now save directly to the new folder that you have created. Task One – to set up a new Project folder The first task when starting a new project in Autodesk Inventor is to set up a new project. Use the As Material feature to render a design Use the Extrude, Shell and Fillet features Sketch complex 2D shapes using basic sketch functionsĪpply dimensional constraints using General Dimension tool Set up a new Project in Autodesk Inventor Inventor Tutorial 1 : Casing Design (press / vacuum forming) By the end of this exercise you will be able to
