1 Classroom rules Tuesday, August 30, :16 PM Rules 1. Respect yourself, your associates, and your school. 2. Enter the room, be seated, and check the board before the bell rings Eyes on the teacher after a triple clap. No use of electronic devices whatsoever. No food or beverages in the computer lab. Move around the room only after receiving permission. Raise your hand for permission or questions. Class Notes Page 1

2 Class Notes Page 2 Re-doing an assignment Tuesday, September 24, :26 AM If you don't receive an assignment when I hand them back to the class: I didn't grade because I didn't have it. You currently have a zero for that assignment. You're falling behind. Re-doing an assignment that's been graded: Eligible if the grade is 80% or less. May earn additional credit, but not full credit. Process 1. Create an entirely new drawing with your corrections. 2. Print it out. 3. Staple on top of your first submittal. 4. Place it in the hand in folder.

3 Class Notes Page 3 Copying Files Thursday, February 11, :01 AM 1. Open Windows Explorer Find the file(s) you want to move in your R: drive Right Click, hold and drag the file(s) into your target folder: For DropBox hand-ins: R:ProjectLeadTheWay\Dropbox\Msnider\Period # For your DDP Honors folder: Your TechArt drive [Never the H: drive, or My Documents] 4. Choose Copy here, from the pop-up menu 5. DO NOT Move your file or just drag and drop, since that will remove the file from your directory and it may get deleted permanently

8 Fixing parts Monday, September 16, :05 PM All sketches should be used up to make a 3D feature (like extrusion). Extra Unused sketches may cause problems in working with your part Right click in the browser bar and delete. Wrong dimensions in your part Either it s the original sketch OR it s the original feature (extrusion, revolve, etc.). You shouldn't [often can't] change an existing feature with a new sketch. Edit SKETCH- Will change something that happened in the 2D world (ex. Geometry like lines, arcs, circles) Right click on the sketch in the browser bar. Choose Edit Sketch from the menu. Edit FEATURE - Will change something 3D about the object (ex. An extrusion depth, a fillet radius, a hole diameter or depth, etc) Right click on the feature in the browser bar. Choose Edit Feature from the menu. Class Notes Page 8

9 Geometric constraints Thursday, October 03, :26 AM Inventor guesses what you want and puts in controls that are called Geometric or Two-dimensional constraints. These controls (constraints) can be removed (or added) by you. Show all constraints Deleting a constraint Creating a constraint Circles and arc all have a center point which can be constrained. Different ways to show coincident constraints: Tutorial file Our version of Inventor Constraint symbols Green, Black, Driven Green line = can still move Black = fully constrained Driven dimension = (#) Driven = forced Class Notes Page 9

10 Work Planes Friday, October 14, :03 PM 1. It s a 3 Click process: 1. Plane: What you want 2. Facing: Which way you want it to face 3. Location: Where you want it In the toolbar, Select plane 2. In the browser bar, Expand the origin; Select a plane to determine facing 3. In the Work Space, Click on 3D feature(s) of your part to set location (Drag for offset ) YZ plane XZ plane XY plane Class Notes Page 10

11 Sweeps Friday, October 11, :57 AM Create a sketch and make the path first. Create a work plane oriented perpendicular to the plane of your first sketch. Click on the end of your path to place the work plane. Place a 2nd sketch on the work plane. Problems with Sweeps? If the sweep won't start: Be sure both sketches are NOT in the same plane. Be sure the profile in the 2nd sketch intersects the path. If the sweep won't finish: Eliminate splits in the path. Be sure there are no gaps in your path. Be sure there is enough room for the profile. Problems: tight curves, spline overlaps. Move the view around until you can see the new sketch and the path. Select Project Geometry, and click on the end of the your path. You should see a small yellow cross. Class Notes Page 11

12 Draw your profile centered on the point you projected. Class Notes Page 12

13 Class Notes Page 13 Splines Friday, October 17, :36 PM Use more than one spline to duplicate a complex curved object. Any place there is a point on the object should be the end of a line or spline. Try moving the curve points to a different place on the spline. Use handles on a curve point to change the angle and distance of tangency. Add or Delete curve points. Use straight lines combined with your splines. Add dimensional constraints to control the size of your shapes. Add geometric constraints to control the behavior of your shapes.

14 Class Notes Page 14 Decals Thursday, October 23, :22 PM Find and save a picture file to your R: drive. In Inventor, create a work plane that is offset from the surface you want to decal. Place a sketch on that plane. Insert image Find and choose your file You can re-size and move the image by grabbing the corners. You can also right-click, on the image, and choose properties

15 Class Notes Page 15 Rotate - rotates the image Transparency - eliminates background Choose the decal feature from the drop-down menu

Linear movement in the Z 4. Rotation around the X 5. Rotation around the Y 6. Rotation around the Z Class Notes Page 20

21 Class Notes Page 21 Fixing assemblies Friday, October 11, :14 AM Assembly problems: Usually one of the constraints is wrong or interferes with another. The easiest method is to erase all constraints for that part and start over. To delete a single constraint: Right click on the constraint in the browser bar. Chose Delete.

38 Design Principles & Elements Wednesday, November 02, :35 PM DESIGN is no mistake! Products are created with an intent and purpose. Every product we own was designed with the core principles and elements of design in mind. Principles: Common ideas or concepts that make a design more appealing. Elements : Visual building blocks used to express design principles. Example: Color can be used to demonstrate emphasis in a design [see page title]. OR: What is the color doing? Is it balancing out the appearance? PowerPoint: <file://r:\projectleadtheway\share\snider\ddp Honors\U6 _ElementsPrinciplesofDesign.pptx> View it in Normal mode in order to read the notes on each slide: Class Notes Page 38

44 Generate Concepts Thursday, December 06, :21 AM Brainstorm Possible Solutions Thumbnail sketches Small examples of some of your design ideas. About the 1/2 size of your thumb, can easily fit on one page. 2 1 Annotated sketches: You need to identify important information. You need to insure that you incorporate that information into your project Write down all design constraints on the edges of your sketch. THEN, draw an arrow on your sketch from the constraint to where your design addresses those constraints. Design Proposal Create a document in MS Word in draft form. Write down all the requirements you've been given so far. Write down all your good ideas Write down design ideas. Be prepared to modify as you build and test your design. Write down the improvements you think you need. Research Pictures Internet 1. RightClick on internet picture, save as a JPEG or JPG file. 2. Open Word document. 3. Choose Insert/ Picture /From File. 4. Find the file saved on your drive. Screen Image [Screen Capture] Class Notes Page 44

45 4. Find the file saved on your drive. Screen Image [Screen Capture] 1. Get the image you want on to your screen. 2. Press Print Scrn key [upper right of keyboard above the Insert key]. 3. Switch to MS Word. 4. Edit/ Paste Special or Ctrl-V. Modifying an image in MS Word i. Re-size: Click on the picture, then click and drag the black squares on the sides or corners ii. Crop - used to cut out edges of the picture Saving Websites Select an Approach Decision Matrix a. b. c. Take out: Write down the categories of things you identified E.g., if you said its fast, the category would be speed. d. e. Combine your lists of categories. Your list should include: All the categories you identified. Major design requirements [HxWxL]. Make a table of your choices and categories: You may use MS Excel, or the Decision Matrix template: : <file://r:\projectleadtheway\share\snider\ddp Honors \Decision_Matrix_Template.doc> f. Score performance of each option Scores should be from 1 to 3 or 1 to 5, with a higher number indicating better performance It s a Score, not a ranking: two designs could have the same number You're evaluating the designs represented by Class Notes Page 45

46 g. your annotated sketches or annotated pictures Don't score a design based on whether the solo design was weak: Add up the scores for each individual alternative, and the design with the highest number is the winner In the event of a near-tie: Go with your gut instincts OR Use the official PLTW tie breaker: Class Notes Page 46
