                    FIRST ANGLE SOLUTION




                    Figure 4.10


                    Open your file for Fig. 4.2 and save a copy with a new file name (say XXX). Erase
                    everything except the required first angle symbol. Repeat the above procedure to
                    make a DXFfile of the symbol, which you will be able to use for this exercise and other
                    applications. Open your file containing Fig. 4.8(a) and save it under a separate file
                    number (say YYY). Erase the two blank views and leave the three orthographic views
                    to the right-hand part of the screen. The reason is simply that when the DXF files are
                    inserted, you need them to appear on an unoccupied part of the screen.

                    Click on Import/Export again in the File menu followed by DXF In. Insert your DXF
                    file number for the isometric drawing in the dialogue box and your previous drawing will
                    now appear. Repeat the procedure for the symbol and insert this drawing.
                    You now have on the screen the component parts of Fig. 4.9. Rearrange them using the
                    Move command and add the first angle solution text. This procedure is regularly used so
                    repeat the exercise for Fig. 4.10 to become proficient in the operation.
