Modifying 3D objects

- [Instructor] There are a number of modifying tools that are unique to working with 3D models. Three of the more important ones are Boolean operations called subtract, union, and intersect. These allow you to combine and remove 3D models to and from other 3D models to create more complex shapes. Here, I have eight objects in four pairs. Each is a box with a sphere placed on the corner. With the subtract tool, the order that you select the objects in is most critical. I'll find the tool here called solid subtract. Now reading the command line, it tells me that I need to select the solids, surfaces, or regions to subtract from. I'm going to select my box here and press Return. AutoCAD then asks me to select the objects to subtract. I'm going to zoom in a little bit and select the sphere here, and then press Return. We can see that the mass that overlapped the two models has been removed. In this case the box remains, minus the area that the sphere overlapped. We're going to try this…
