AutoCad - Combine, Splice, And Dice 2D Objects (2004/2005/2006/2007)


Suppose you would like to create an object that is the intersection of two other objects. Or perhaps you would like to combine two objects or subtract one from the other. If you commonly work in 3D, this is a very familiar scenario, but if you don't, you may not be aware that you can perform these operations on 2D objects.


You use the REGION command to create 2D surfaces that act a little like 3D objects, such as:


  • Create holes in them or otherwise subtract one object from another.
  • Create an object from the intersection of two or more of them.
  • Combine objects together.

Let's say that you want to create an object that is the intersection of a rectangle and circle. You could do a lot of trimming and erasing, but you could try a simpler procedure—converting the objects to regions and performing the INTERSECT command on them. Just start the REGION command (it's on the Draw toolbar) and select the two objects. Then use the INTERSECT command and select the two regions again.
