Carving a volume out of solids
In Worldcraft, any solid can be used to carve a volume out of other solids. For example, you can place a solid within the room's wall and tell Worldcraft to subtract the solid from the wall - effectively punching a hole right through the wall! This feature is not limited to using cubic shapes as a carving tool: any solid - cylinders, cubes and wedges - can be used to carve other solids.
While carving, especially with a cylinder, it is best to carve the smallest areas possible. What tends to happen is you have an area you want to punch a hole in, so you make an object with the same shape you want the hole, say for example a cylinder. If you take that cylinder and carve a circle out of a large wall, the whole wall will be broken up. Instead, a more efficient way to carve would be to first carve a square hole (the same size as the circle) and leave the square in place. Then you can take the cylinder and carve a hole in the small square. This will eliminate the splintering effect for the wall.
Carving a volume from a solid
Carving in Worldcraft is a simple task.
step 1. In this step, you have the object you want to carve into (in blue), and the object you will be carving with (in red). You should have the red object selected.
step 2. Position the carving object so that it is where you want the hole to be.
step 3. Press Ctrl+Shift+C, or right click on the selected object and select Carve. You can also press the Carve button on the MapOperations toolbar.
step 4. Either delete the object you used to make the carve, or you can now use it to fill the hole, as a door for example.
Note: In the picture labeled result, you can see that the cube (which was previously one object) is now broken into 4 separate objects. This is because the game engine cannot handle concave objects, and Worldcraft has broken it into convex pieces.
