6th Year

Your November Assessment will be based on your work on the DCG Student Assignment. The outputs below will be marked as a finished Leaving Cert project and marks are broken down as follows:
See the webpages for each output for a further breakdown of the marking scheme. In particular, pay attention to the checklist for each output to make sure everything is there. 

Work is due by Wednesday 12th November. 
To submit your work, create a folder in Google Drive and save the following files in it:
  • Output 1- [yourname]
  • Output 2 - [yourname]
  • All CAD files (parts, assembly and eDrawing)
Then share the folder with Mr Bates.

Summer 2014

The 5th Year DCG assessment will have 3 parts:
  1. 2 hr written exam                    (50%)
  2. 80 minute Solidworks task    (20%)
  3. Coursework                              (30%)

1. Written Exam - 50%

The written exam will take place during house exams in the week 26th - 30th May. It will be held in Room 6. 
The exam will be modeled on the DCG Leaving certificate exam:
  • Short Questions - choose 3 out of 4 (section A of Leaving Cert)
  • Long Questions - choose 2 out of 3 (section B & section C of Leaving Cert)

All aspects of the DCG core (section B) could be examined and the Surface Geometry option from Section C could be examined.

2. Solidworks Task - 20%

Solidworks skills are crucial for the DCG project next year and will play a big part in your final DCG result in the Leaving Cert. You will be given a part to draw in Solidworks and will have one double class (80 mins) to do this. This test will take place on Thursday 22nd May during normal classtime. 

You will be given a real object made up from several parts. You will need to measure the object, create a model of each part and then put the parts together in an assembly.

For revision, check that you can:
  • Constrain a sketch using smart dimensions and relations
  • Extrude (including draft angles)
  • Revolve
  • Cut
  • Use linear and radial patterns
  • Use a swept cut
  • Work with reference planes
  • Apply colour to parts
Important things to consider are:
  • Accuracy - does your model accurately represent the part given?
  • Design intent - are you making your part as simply as possible? Are you using mirroring, patterns, offsets and so on so that the part is easy to modify?
  • Relations - are you using relations in your sketches where possible?
  • Naming features - all features must be named (not just BossExtrude4)
  • Sketches constrained - all your sketches must be constrained (ie, black instead of blue so that all dimensions are defined)

These are the same issues you'll be marked on in the Leaving Cert so it's worth getting used to them now.

3. Coursework - 30%

This is an assessment of classwork and homework done during the final term. Please select your best drawing for each of the following:
  1. A Leaving Cert Section B question that includes Conic Sections. (2012 B-1 or 2011 B-3)
  2. A Leaving Cert Section B question that includes Perspective. (2013 B-3 or 2010 B-1. Note the full question must be submitted)
  3. A Leaving Cert Section B question that includes Intersection of Solids. (2012 B-2, 2011 B-1, 2009 B-3. q20 p295 may also be submitted.)

All course work must be clearly marked with your name and must be submitted before the 23rd May.
