Lesson 2 > 4 > Solid Subtract / Union / Intersect in AutoCAD

2.4.1 Solid Union

It is used to combine the two solid objects. So that one object passes throughout and other one gets split up. Figure 2.4.1 will help you to understand the Solid union. This method is most suitable for combining two objects. Which is used for the best architectural appearance.

2.4.2 Solid Intersect

 In this type when two solid cross each other, then the area which is in contact with each other only remains. It removes the area which is not in intersection with those two objects.

2.4.4 Completing the 3D Model

  1. In the previous chapter we have created a model which is looking somewhat like the in the image below:
    Figure 2.4.4 : Previous Model
  2. Now you have understood what we have to do. We need to apply the command of solid subtract. For that first we will select the walls and then the window or door box. After that your work will look like in the image below.
    Figure 2.5.5 : After applying Solid Subtract Command.
  3. But it will look wired if we don't have slab on it. For that switch to top view with poly line create the outer border and then apply the extrude command. And here is your 3D model completed and will be looking like this.
    Figure 2.5.6 : After Adding Slab
  4. Here is your model completed. You can change the color of walls by going to its properties and selecting the color. And here i am happy to say you have completed the BASIC 3D & 2D drafting Tutorial.
