== =Introduction to modelling=

==Turning ideas into three-dimensional models is a way of developing design thinking and communicating it to other people .Professional designers are interested in models for many different reasons .Those building large and exspensive projects ,for example a chemical plant,build huge scale models of pipework that can cost anything up to a million pounds .These models, however , can save many more millions by showing up possible mistakes before building starts on the real thing .== ==You dont have to build huge models costing millions of pounds, this was just an example of how things out in the designing world can be .There are many techniques for creating your idea and building your own 3-D model .We are now going to have a look at a few simple methods of putting our designs and what we are thinking together with the use of models.==

=Paper and Card Models=

==These are commonly used materials because of the range of sheet thickness, colours and finish available ,in addition to their comparative cheapness ,their ease of working and because most glues will stick them .However ,if a good standard of work is to be maintained certain procedures must be observed .==

**Technical Drawing.**Accurate models can only result if precise drawings are made of the surface development of a 3-D solid object.
=__STEP 2__= ===Developments.By using drawing instruments and adhering to correct drawing techniques, it is possible to draw the sides of almost any solid object on a sheet of paper or card so that they can be folded to make the form of the required object. Developments should be drawn so that they are made up of as few seperate pieces as possible and in one piece if pracical.=== =__STEP 3__=

Geometric form.Most artefacts around us are made from geometric forms. Therefore, it follows that the best way to learn to make developments is to practise on gradually more geometric solids.
=__STEP 4__= ===Detailing.One of the great advantages of using paper and card to make models is that the addition of small intricate details can be done very simply by drawing them onto the flat development and colouring them before it is even cut out. In this way quite simple but realistic models can be made.===
