Transferring the design to CAD – 2D Design

1. In this presentation we are going to focus on designing and modelling skills Transferring the design to CAD – 2D Design Cutting out the design using CAM Designing by modelling with card Folding using a strip heater….. Applying graphics to the final product. ….. and jig

2. Let’s start designing. Modelling is an important part of this unit. Modelling can be a helpful way to design. It can help you to judge the size, proportion and overall look of a design idea. In this task you will have an opportunity to model using: • squared grid paper – you can draw your design on this, cut it out with a scissors and test how effective it is. • a computer programme e.g. 2D Design to develop your idea and then cut it either by hand or using a laser cutter/CAMM2 Designing – modelling

3. Modelling using squared grid paper. • To help you get started, your initial designs will be drawn on 1cm squared card and will be in 2D (a net on card). • These 2D designs will then be cut out as card models, folded and made into 3D models. • Attempt to produce 3 designs. Selecting the best design for developing into your final design. Designing – modelling

4. The animation shows you how to create your card models. Wait a little for the animation to start. Designing – modelling

5. The photos show pupils working on their paper models to solve their storage problems. Designing - modelling

6. Modelling using computers can be very effective, you can draw and change your ideas, store them and then send your final design to CAM equipment for manufacture. Task - Follow the steps shown in the animation for an idea for a basic mobile phone holder. This will enable you to be familiar with the commands needed for this task in 2D Design. Print the final outlines onto 1 cm grid card, cut out the parts and assemble. The next slide is an animation showing how you could develop your design ideas using 2D Design using a 1cm grid. Designing – modelling

7. I’m down here, now look at the screen Now copy this on to 1cm grid card, cut out and assemble. There is 1 cm between each dot. Let’s get rid of some of the straight lines by adding a few curves Now let’s design the supports. The lines for the slots are in red. Now let’s add some style to the shape by rounding off the sharp corners.

8. Getting ready for Making Once you have completed your card models and decided on your final design you will need to copy it into 2D Design Save your finished design and prepare to cut the shape out using CAM equipment e.g. Camm2 or laser cutter. Also print 3 paper copies of your final design, these will be helpful to develop and test your ideas for any graphics you may want to add to your storage product.

9. In this next slides we are going to look at other pupils’ products for inspiration. • Think about : • the outline shape • construction techniques used • colour combination of materials • impact of graphics.

10. Here’s how other pupils solved their storage problems. Hopefully these will give you inspiration for ideas. Storage products made using slotting and bolting

11. 10mm ABS Tube – 6mm bore various colours Dome nuts 6mm threaded rod Foamex Another method of construction your storage product would be to use threaded rods, ABS tubing and dome nuts. Examples of products using this method are shown in the next slide. Here are examples of the supports that can be used to hold the product in a stable and upright position.
