Overview

We will now create a drawing which will be used to investigate several new topics, e.g. using the modify commands, adding text and dimensions, etc. This working drawing will be created from lines and circles and is relatively easy to complete, so:

1. Open your A3PAPER standard file drawing or template.

2. Refer to Figure 11.1 and:

   1. draw full size the component given

   2. ensure that layer OUT is current

   3. a start point is given USE THIS START POINT AS IT IS IMPORTANT FOR FUTURE WORK

   4. do not attempt to add the dimensions

   5. use any entry method suitable but I would suggest:

      1. absolute co-ordinates for the (80,110) start point then relative co-ordinates for the outline

      2. absolute co-ordinates for the circle centres (some 'sums' needed).

   
   Figure 11.1: Creating the working drawing C:\MYCAD\WORKDRG.

3. When the drawing is complete, menu bar with File-Save As and:

   prompt	Save Drawing As dialogue box
   with	File name: A3PAPER
   respond	ensure C:\MYCAD is current folder to Save in alter file name to: WORKDRG pick Save.

4. We have now opened our A3PAPER file (drawing or template), completed a drawing exercise and saved this drawing with a different name to that which was opened.

5. This is (at present) the method which will be used to complete all new drawing exercises.

6. Now continue to the next chapter.

7. Note: It should be apparent that the circles will be drawn without centre lines. This is deliberate, as it will allow us to investigate other CAD draughting...
