Boolean Triangles Example

This example looks at creating two triangle primitives (a cone and a block) and then use the block to produce a cropped cone. Workplanes are also used to create the block at a suitable angle.

1. Initially create a cone by clicking on the Cone tab on the Create Triangle Primitives dialog box (available from the Triangle Modelling toolbar ).

   

2. Accept the default values of Height 100, Diameter 100, Position X 0, Y 0 and Z 0 and then click on Create.

   

3. You can see the CONE model in the Explorer.

   

4. The next process is to create a block, at an angle, on the top of the cone.

   

5. You could do this by creating a block at the origin and then transforming it. However, an easier way (especially if you want to create more than one item in the new orientation) is to create a workplane in the correct orientation and then create the block using this workplane.
   
   
6. Create a new workplane by selecting Create Workplane from the workplane right click menu.

   

7. In the Workplane dialog box:
   • click to select the Active check box.
     
     
   • enter the origin of the workplane to be 0, 0, 40 in the Edit area
     
     
   • specify an Angle of 30 in the Twist area
     
     
   • click on the button to rotate the workplane about the X axis. Then click on Apply followed by Accept.

     

8. You will now see the new workplane. For the rest of this example you can keep this workplane as the active workplane. However, if you want to create any more models you must choose the appropriate workplane (or global transform) to get the appropriate orientation.

   

9. From the Explorer right click on the workplane that you have just created and select Activate to make it the Active Workplane .

   

10. Return to the Triangle Primitives dialog box click on the Block tab

    

11. Enter the values of Size X 40, Y 40 and Z 40, Position X 10, Y 0 and Z 0 and then click on Create followed by Accept to close the dialog box.

    

12. You can see the BLOCK model in the Explorer.

    

13. Make the cone the active model .
    
    
14. From the Boolean Triangles dialog box select the Boolean Operation of Remove and select the Secondary triangle model of BLOCK and then click on Apply.

    

15. You will now see the cropped cone.

    

16. You will see that one workplane and three models have been created during this process.
