2.- DRAWING WITH CAD

We will use QCAD to make clear and precise drawings with a computer.

1.       Using the tool polinea and absolute and relative coordinates of the previous year European system perform the following drawing.   

1) We draw the views with draw line for 2 points. Before we will have created a layer called the continuous line of thickness 0.6

 2) we create a new layer called the dimensions and limit the figure.

3) make the layer dimension is invisible.

4) select the view and transform them into isometric, doing the figure as shown in the following video. 

  

Now we are going to build a box with lettering using draw rectangle line and properly choosing the same corners. We then define another green coat and completing the box. Finally we define a last layer and limit.   

-In the last figure, you will have to use drawing tools and modification.

1) draw 2 circles of 10 radio separated a distance of 70 (centers)

 2) to 15 of their centers and separate 10 outlines 2 lines paraleas

3) below are drawn tangent.

 ((4) are rounded with angles of 60 °

5) to delete the part of the circles, one should begin

 6) outlines the internal diameter (radio 5) 10 circles

7) is finally refine defining a layer to do so.
