ADVANCED BRIEF
Your company - Pulleys Inc. - must modernise their current Product Range of items. They produce this Adjustable Pulley using Imperial sizes and now need a METRIC version.
UNIQUE DIMENSIONS
Use the dimensions provided. Convert them to metric equivalents (eg 1” = 25.4mm). Round all dimensions up or down to nearest 0.5mm. Each student has a unique set of dimensions that we have calculated based on your SID number (see pages 4-5). Use these to complete the missing dimensions in the drawing.
WHAT YOU SHOULD DO
Model all components, assemble them and complete draft drawings of ALL component parts using the variable dimensions you have been given, use your ENGINEERING KNOWLEDGE to add detail at your own discretion.
a) Each component MUST be modeled in a separate part file. b) Add all files to a single ZIP file. c) ENSURE YOUR FILES OPEN ON A UNI PC, IF I CAN’T OPEN ALL FILES, THEY
WILL SIMPLY BE MARKED A ZERO. d) Produce a PDF draft drawing (Using ‘save as’ in Catia) for EVERY component. e) Combine documents in a single PDF (BINDER) to submit online.
Submit only your own work. Plagiarism and will cause you to fail the coursework. Data saved with every CATIA part that tells me who the author is, I will know anyway.
ITEMS TO BE SUBMITTED ONLINE
One ZIP file containing; Folder 1 – CAT Parts. Contains ALL component parts and assembly. DO NOT save parts and assemblies into different folders for submission, this may cause them not to open correctly. Each component must have a unique Part Number (at your discretion). Folder 2 – Binder of PDF Drawings. 1. Fully dimensioned 3rd angle orthographic of all components with correct border.2. One-off exploded drawing and one-off assembly drawing following the guidance given in appropriate literature (eg Library).

«M2__Complete» Generally all of your models opened without a hitch, however some of you renamed components and hence they would not work.
Logic of construction and intelligence of build.
12.5% Poor attention to construction detail with poor Part-Tree. Little or no components contain data of appropriate material detail. Little or no consideration of dress-up tools and features used that allude to manufacturing method. No use of Knowledgeware. Clear problems with conversion of dimensions.
Little attention to construction detail with satisfactorily sized Part-Tree. Little or no components contain data of appropriate material detail. Little consideration of dress-up tools features used that allude to manufacturing method. No use of Knowledgeware. some problems with conversion of dimensions.
Good attention to construction detail with appropriate sized Part-Tree with appropriate tools used. Some components contain data of appropriate material detail. Suitable consideration of dress-up tools features used that allude to manufacturing method appropriate to this type of assembly. No use of Knowledgeware items to allow for quick updating and editing of the product in future. Appropriate conversion of dimensions to allow for METRIC construction with no items clashing in the assembled product file.
Very good attention to construction detail with appropriate sized Part-Tree with appropriate tools used. All components contain data of appropriate material detail. Suitable consideration of dress-up tools features used that allude to manufacturing method appropriate to this type of assembly.

Outstanding attention to construction detail with appropriate sized Part-Tree with appropriate tools used. All components contain data of appropriate material detail. Excellent consideration of dress-up tools features used that allude to manufacturing method appropriate to this type of assembly. Excellent use of Knowledgeware items to allow for quick updating and editing of the product in future. Appropriate conversion of dimensions to allow for METRIC construction with no items clashing in the assembled product file.
«M1__Logic» Most people lost marks here as a result of not using appropriate metric conversions ie. 1 inch = 25.4mm and the APPROPRIATE conversion would be 25mm or 25.5mm or even 26mm. Three people in the class actually made an good conversion and as a result they received a 7+ score, the remainder of you are probably somewhere around 6.8, regardless of how good your model was. Look up ‘task compliance’.
Quality of parts from / intelligence of build.
10 Poor knowledge of Sketcher workbench with majority of sketches not iso-constrained. Erroneous sketches in Part-Tree and items requiring update. No use of Knowledgeware items to allow for quick updating and editing of the product in future.

«M4__Border» Please see appendix 1 for a list of mandatory fields taken from BS EN ISO 7200. It says here clearly you should construct your own title block, therefore if you used a stock template you did not get over 40%.
General Presentation and positioning of drawings on page.
10 Poor use of space on page with incorrect scales used. Little or no use of auxiliary drawing to help present the item. Problems with understanding of 3rd angle orthographic.
Satisfactory use of space on page with incorrect scales used. Little or no use of extra sheets to present extra detail. Little or no use of auxiliary drawing to help present the item. Problems with understanding of 3rd angle orthographic. Little or no use of lines such as phantom lines, breaks, centres of hidden line detail and appropriate to the presentation of the part.
Good use of space on page with correct scales and presented neatly. Some use of extra sheets to present extra detail if necessary. Some use of auxiliary drawing to help present the item.

Very good use of space on page with correct scales and presented neatly and concisely. Very good use of extra sheets to present extra detail where necessary. Very good use of auxiliary drawing to help present the item. All items drawn in 3rd angle orthographic with some use of isometric detail for better presentation. Some use of line such as phantom lines, breaks, centres of hidden line detail and appropriate to the presentation of the part.
Excellent use of space on page with correct scales and presented neatly and concisely. Intelligent use of extra sheets to present extra detail where necessary. Outstanding attention to use of auxiliary drawing to help present the item more completely. All items drawn in 3rd angle orthographic with excellent use of isometric detail for better presentation. All linetypes such as phantom lines, breaks, centres of hidden line detail appropriate to the presentation of the part.
«M5__General_Present» All items should have been in PDF not in the native CATDrawing file, this was defined specifically in the handout. One page = one component, I said this in the BS8888 lecture, if you had multiple components on the same page you lost marks. You should have used scales set out in BS8888, alarmingly though some of you had a discrepancy between the scale stated in the title block and the actual views on the drawing. Consistency please.
Dimensions. 15 Poor positioning of dimensions with unnecessary obstruction or crossing of lines. Illegible from two directions. Unclear as to what is a dimension line and what is the image being dimensioned. Poor level of understanding of construction requirements by use of dimensions appropriate to the manufacture and finish of the component. A lot data missing from that required for construction. Missing dimensions leading to manufacture of part.

«M6__Dimensions» Please re-read the advice in the 70% box, I’d just be repeating myself. What I found most interesting is where some people had 2-3 font types and varying sizes, find some examples of drawings to try and learn from. Dimensions falling over drawings unnecessarily was also something a lot of people were guilty of, confusing the drawing completely. The biggest problem I saw though was line thicknesses whereby all but about five people had used the same line thickness for the dimensions as they did for the profile of the part. I know the most common response would be “but Catia did it automatically that way”, you should have changed it so there was a clear difference. Knurling is presented in a specific way if you check BS8888, a lot of you did a very good job of modelling it, but when it comes to presenting it on a drawing you do not need the detail of the grooving.

General Note The biggest problem with everyone’s handin last year was something called Task Compliance. Put simply, many people did not read the marking criteria, and simply lost marks as a result of not handing in the basic requirements.. The mark scheme above was handed out with the original document and has been on moodle throughout, it also highlights which areas to target your research as they are generally weighted much higher. As a result you will see that the grading for each area does not strictly tally with your overall grade as I’ve had to moderate the marks up by adding a multiplier, just because otherwise most of you would have failed. Overall though I was impressed with the general ability to operate CATIA. The aim of this coursework (as highlighted above) was for you to present your parts correctly in accordance with industry standards (BS8888 and related documents), which required as much research on them as it did to draw the parts.
