You have now learned enough about drawing that you should be able to enter XY coordinates and draw some simple geometry. The following will get you to the next level. That is being able to draw some geometry that requires more attention to detail.
Drawing Circles
Start a new program called “Test6”. Select Draw, Circle, Diameter, Center, a window will ask you for a diameter value, enter 1 and click O.K. The prompt it will ask you to enter the XY location for the center of the circle. Enter “X1” and “Y1” for your coordinates. Then enter the same coordinates with the sign modified so that the four quadrants have equally spaced circles.
Now select Draw, Circle, Diameter, Blend 2 Items, a window will appear asking for a diameter value, enter 2 and click O.K. Now click on the top left circle once and then the top right circle, you will now see four ghost circles. The locations of all the ghost circles are the possibilities for blending a 2-inch circle to the two 1-inch circles. Select the circle at the highest point by clicking it once. The drawing should now look like the picture on the left. Do the same to the remainder of the circles; your picture should look like the one below.
Now that you have all your circles in place you will need to split them. CleanUp can do this very nicely, along with splitting and removing overlapping objects CleanUp will also split full circles. Select Modify, CleanUp, a window will appear asking “Split Full Circles?” click “Yes”. Now you have an eraser as your pointer. Click on the geometry that is not needed so that you end up with a picture like the one below.
What Is A Shape
A shape is number of objects positioned together to make a pattern. A rectangle is a shape; it contains lines and maybe arcs. A bolt circle is also a shape; it contains circles or points equally spaced and around a point of rotation. There are a number of patterns that can be created as a shape. For a list of them, look under Draw, Shapes. You can also create a shape by drawing individual objects and placing them at a precise location, a shape always has all objects linked together by start point and/or end point of the individual objects.
Creating A Bolt Circle
Select Draw, Shape, Bolt-Circle, a window will appear asking “How Many Holes?” Enter 5 and click O.K. A second window will appear asking for the “Bolt-Circle Diameter” enter 3. Now a third window will appear asking the “Hole Diameter?” Enter .25, and finally a fourth window will appear asking for the “Starting Angle Of First Hole?” enter 90. Now the prompt will ask “Enter XY”, type your coordinates “X3” and “Y3” then confirm your location. A bolt circle will appear on the top right quadrant of your screen. Now type the XY locations for the remainder of the quadrants changing the sign for the XY locations as needed. Your drawing should look like the picture illustrated on the left.
Creating XY-XY Line of Points
On the same drawing Select Draw, Shapes, XY-XY Line of Points, a window will appear asking “How Many Holes?” enter 5. Then a second window will appear asking “Hole Diameter”, enter .5. The prompt will now ask “Select Start XY”, type X6 and Y-6 for the starting point and confirm your location. Now the prompt will ask “Select End XY”, type X6 and Y6 for your end point and confirm your location. Now do the same on negative side of X. When done your drawing should look like the picture illustrated on the left.
Creating Angle Line of Points
Select Draw, Shapes, Angle Line of Points. It will ask how many holes, enter 3, then it will ask you for the hole diameter enter .125, then it will ask you for the angle of line of holes enter 0 and finally it will ask for the distance between holes enter .5. Now enter the coordinate of X1 Y0 and confirm the location. Now go to the action buttons and click on angle, change the angle to 90 degrees and type in the coordinate of X0 Y1 and confirm the location. Continue to change the angle and the XY coordinates so that the hole pattern looks like the drawing.
Creating a Grid of Points
Select Draw, Shapes, Grid of Points, it will first ask you “Hole Diameter” enter .25. Then it will ask you how many holes in the X direction, enter 3. Then it will ask you how many holes in the Y direction, enter 3. Then finally the prompt at the bottom will ask you to select start XY, enter X –2 and Y 5 for the starting location and confirm the location. Then the prompt will ask you to select the opposite XY, enter X2 and Y7 and confirm your location. Now do the same in the Y negative so that the your drawing looks just like the one below.
Creating a Rectangle
Select Draw, Shapes, Rectangle, it will first ask you for a Radius Value, this radius will be the corner radius, enter .5. The prompt will now ask you for Start XY, enter X-7.5 and Y-8 then confirm the location. The prompt will now ask you to select the opposite XY, enter X7.5 and Y8 then confirm the location. The drawing should now look like the one illustrated on the left.
