As we work through the sample tutorials, we're going to assume that you have
a good working knowledge of CorelDRAW. For those who don't, we suggest you
get a copy of CorelDRAW X4 Unleashed.
In this first project, we're going to create the beginnings of an exploded
parts drawing. We'll start by drawing a nut and a washer. Because of minor
differences between CorelDRAW 7-X4, we'll be using the generic name
of the command and not the exact menu command.

Turn on Snap to Grid so that we can draw objects of an exact size.
Make sure you have the grid set to 16 gridlines per inch.
Draw a rectangle that is .25 inches wide by 4 inches tall. It is
important that you draw it this exact size and not stretch an existing rectangle.
Round the corner of the rectangle to a radius of .0625 inches. This
should be one "notch" as the radius will snap to the grid.
Convert the rectangle to curves.
Select all the nodes with the Shape tool and convert all line
segments to lines. This should square off the roundness at the ends of the rectangle.
Rotate the rectangle around its center by 15 degrees and use Apply to
Duplicate so that you'll have two rectangles. Repeat this ten more times
so that the rectangles rotate in a full circle.
Draw a circle that is 3.5 inches in diameter.
Align the circle so that it is centered with the rectangles.
Weld the result together.
Draw another circle that is 3 inches in diameter.
Align this circle to the center of the welded piece and Combine them together.
Go ahead and fill this piece with a light gray.
Congratulations, you've created an orthographic view of the washer. Next we
next to create an orthographic view of the nut. It will be a bit easier.
Draw a six-sided polygon that is 5 inches square. Polygons have
extra nodes at the midpoint of each side that you'll want to remove.
So press the Ctrl-Q shortcut key to Convert to Curves, select all the
nodes and press the Auto Reduce button on the Property Bar.
Draw a circle that is 3 inches in diameter.
Align the two objects so that they are centered and them Combine them.
Fill this object with a slightly different shade of gray.
OK, we've now got both of our parts finished. Note that the dimensions of these
objects are somewhat unrealistic. Feel free to draw them at smaller sizes
if you desire. Now we're ready to start converting these objects from the
orthographic view into a projected view. We'll use Isometric since it is
the most common method used. But you can easily do this project with any
of the five projections without changing any of the steps.
Select the washer and the nut.
Center them with each other.
Since the nut is hiding the washer, reverse the order of the objects.
With both objects still selected, choose Isometric from the drop-down
list in EZ Metrics if it isn't already selected. Make sure the Create Face
radio button is selected. Now click the Left face icon on the top
projection model (the one on the left).
We want to give these objects a thickness. Remember that our nut was 5
inches square so let's give it a thickness of 2 inches. So we need to
Extrude it 2 inches to the upper right. Note that you must have only the
nut selected or you will get an error message.
Repeat this process with the washer using a thickness of .125 inches.
Now we need to explode our drawing. Change the move distance to 2 inches
and click the blue arrow in the lower left.
See how easy it was to take the orthographic view and turn it into a 3D exploded view!
