HSC Assessment Task 4 Major Project Development

Now you have developed a series of high quality annotated sketches that demonstrate the development of ideas, you have then justified your design choices and related them to your statement of intent.  You are ready to draw your design in Onshape. The purpose of a CAD model drawn in Onshape is to test and modify your designs, you will then develop accurate working drawings in the next task (4f). 

Tips for success:

• Using Onshape, ensure you have set the document to millimeters. 

• Any dimension you draw in Onshape needs to directly relate back to an actual size of timber you can purchase from Mathews Timber or Bunnings. 

• As you go through drawing your project on Onshape you will make modifications to your design and record them by taking a screen shot of an image and inserting it with an annotation in your portfolio under the heading (Development of Ideas - Prototyping, modelling and testing). This demonstrates your skills and design knowledge of your project.

You can develop quality production and working drawings of your chosen design/s, using CAD software such as Onshape.  

Working drawings are two-dimensional orthogonal projections of the project which clearly demonstrate dimensions. A high-quality working drawing is used throughout the construction process of a project and is referred to for specific dimensions and joinery. 

Tips for success:

• Refer to the exemplars below to guide your working drawings. 

A cutting list clearly outlines all required members for your project, it stipulates the length (L), Width (W) and Thickness (T) and what material this is made used.  You will use the information from your list when purchasing your materials.
