Transferring the design to CAD – 2D Design

Cutting out the design using CAM

Designing by modelling with card

In this presentation we are going to focus on

designing and modelling skills

Designing – modelling

Let’s start designing.

Modelling is an important part of this unit.

• squared grid paper – you can draw your design on this, cut it out with a scissors and test how effective it is.

In this task you will have an opportunity to model using:

• a computer programme e.g. 2D Design to develop your idea and then cut it either by hand or using a laser cutter/CAMM2

Modelling can be a helpful way to design. It can

help you to judge the size, proportion and

overall look of a design idea.

Designing – modelling

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).

• Attempt to produce 3 designs. Selecting the best

design for developing into your final design.

• These 2D designs will then be cut out as

card models, folded and made into 3D models.

The animation shows you how to create your

card models. Wait a little for the animation to start.

The photos show pupils working on their

paper models to solve their storage problems.

Designing - modelling

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.

I’m down here, now look at the screen

Now let’s add some style to the shape by rounding off the sharp corners.

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 copy this on to 1cm grid card, cut out and assemble.

There is 1 cm between each dot.

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.

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.

Here’s how other pupils solved their storage problems. Hopefully these will give you inspiration for ideas.

Storage products made using slotting and bolting

Here are examples of the supports that can be used to hold the

product in a stable and upright position.

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.
