To perform a Boolean operation between Solid3d objects inside AutoCAD, you can use Solid3d. BooleanOperation() on the primary Solid3d, passing in the secondary one. We want to implement commands for Unite (or Union), Intersect (Intersection) and Subtract (Subtraction).
What is Boolean operation in AutoCAD?
See moreA Boolean object combines two or more objects by performing a logical operation on their geometry. The objects typically overlap, but they don’t have to. The original two objects are the operands and the Boolean object itself is the result of the operation.
What are Boolean operations in AutoCAD 3D?
There are three Boolean operations defined in AutoCAD 3D, which are given below: Union. Subtract. Intersect.
What are the three Boolean operations in solid editing?
Two solid objects can be combined into one object in various ways using operations known as Boolean operations. There are three basic Boolean operations: JOIN (Union), CUT (Difference), and INTERSECT.
What is Subtract command in AutoCAD?
With SUBTRACT, you can create a 2D region object by subtracting one set of existing region objects from another, overlapping set. You can select only regions for use with this command. … Objects in the second selection set are subtracted from objects in the first selection set. A single new region is created.

If you’re inside a command, selecting objects, and at the Select Objects prompt, you can type R <enter> and you will be prompted to Remove Objects. This removes them from the selection set.
What is CSG tree?
Constructive solid geometry (CSG) defines objects as Boolean combinations of primitive solids, and usually stores them in binary trees. A bounding entity is an upper estimate of the extent of a CSG object.
What is meant by CSG?
Constructive solid geometry (CSG; formerly called computational binary solid geometry) is a technique used in solid modeling. … In 3D computer graphics and CAD, CSG is often used in procedural modeling. CSG can also be performed on polygonal meshes, and may or may not be procedural and/or parametric.

What is intersect in AutoCAD?
With INTERSECT, you can create a 3D solid from the common volume of two or more existing 3D solids, surfaces, or regions. If you select a mesh, you can convert it to a solid or surface before completing the operation. You can extrude 2D profiles and then intersect them to create a complex model efficiently.
