Solids parts in ACAD 3D have a specific group of modifier commands. Now we will discuss how to use the Subtract command in the Solids Editing tool position group (in CAD 2010) as shown.

From the figure, it can be seen that in the process of subtracting or cutting the part of the workpiece, there must always be

1. the main workpiece to be kept and 2. the workpiece to be cut out, and the important thing is that these two parts must actually intersect is that there are parts of the work that overlap therefore will be able to get the results as desired.

Let’s create 3 solids 3D pieces, one green box and two red boxes, positioned as shown.

Set the Green box to be 1. The main workpiece to be kept. The Red box is 2. The work piece that will be cut out Then select the Subtract command and select the 1st piece first and enter to finish the selection process. Later, select Box 2 (until all 2 workpieces are completed) to be the cutter and then enter the result as shown.

You will see that Box 2 has disappeared, leaving only Box 1 that has been cut to the size of Box 2 that the arrow is pointing at. The principle of subtract is subtraction, that is, there must be an indenter (which must be larger in size) and a subtraction (smaller in size). and there are more than 1 piece) Sure enough, try it.
