METBD 110 Hands-On 3:Solid Models and Orthographic SketchingWhy:Learning Objectives:Performance Criteria:Resources in addition to Previous Hands-On Web Sites, Other Students, Class Notes, and Instructor:Plan:Why: Solid models and orthographic projections are two tools commonly used to communicate information in the engineering design setting. In this activity, you will learn how to obtain size and shape information from a solid model and how to represent this information in the form of an orthographic projection sketch. Learning Objectives:- Be able to identify the different features of an object.- Start the Pro/ENGINEER software and open a file from the courseware data disk. - Rotate and measure a part in Pro/E- Sketch specific orthographic views of a part taking the size and shape information from a Pro/E model.Performance Criteria:- Properly fill out a modeling strategy form.- The sketch is done in a neat and professional manner using the proper border and lettering.- Sketched views are properly oriented and lined up.- Sketched views and 3-D model are the proper shape and size.Resources in addition to Previous Hands-On Web Sites, Other Students, Class Notes, and Instructor:8/6/03 1 of 3METBD 110 Hands-On 3: Solid Models and Orthographic Sketching- Sketching Border and Title Block – Penn State Graphics Standards & Angel- Dimensioning Module, Lesson 2 - Reading Assignment- Measuring a Part Video8/6/03 2 of 3Plan:1. Read the web pages listed above. Keep a printed copy of the documents in your notebook. 2. Access the Pro_E courseware datadisk. (Use Accessing Courseware Data Disk web link.) 3. Start Pro/ENGINEER (Use Starting Pro/ENGINEER web link.) and set your working directory to: PRO_E on ‘PSBDFILESRVR’ (V:)\METBD_110\Orthographic\ (Use Setting the Working Directory web page.) 4. Open the part file named ‘Ortho_01’. (Use Opening Pre-Existing Files web link)5. General Information:a. Design Intent: Material is important.b. The general tolerance will be ±.01.6. Complete a modeling strategy form for ‘Ortho_01’.7. Sketch the 6 principal views on engineering calculation paper.a. Sketch the border and title block on engineering calculation paper. (Use Penn State Erie Drafting Standards web link) b. Calculate dimensions needed to center the six principal views on engineering calculation paper. Leave 1.4” of space between the views. The views should be properly arranged and aligned and centered on the page between the views. Remember each grid = .20.c. Obtain the object’s dimensions using Pro/E. (Reading assignment & video.) d. Lightly block in the views on engineering paper. e. Using the modeling strategy, sketch the views one feature at a time on the engineering paper.i. Sketch the 2-D shape, to scale, in all 6 views and add dimensions keeping design intent in mind. 1. For example, H shape: the vertical legs may be 2” high by .5” wide. The horizontal leg may be .5 high and centered height wise between the vertical legs. ii. Finish sketching the feature, in all 6 views, and add the extrusion dimension.iii. Repeat for the rest of the features.f. Darken the views and neatly print the name of the view below the appropriate view.8. Using the sketch created in step 7, model the part out of clay.a. Your instructor will start with a block of clay larger than the overall size of the object.b. Scribe the 2-D shape of the appropriate feature.c. Extrude, cut, the shape to appropriate 3rd dimension.d. Repeat steps for each feature.9. Complete the six principal planes on engineering paper for the next class. After the dimensioning lecture, completely dimension the part using 2-place decimal unidirectional chain dimensions. 8/6/03 3 of
