In fact, any solid features we create in 123D Design are used as primitive solids parametric modeling allows us to maintain full control of the design variables that are used to describe the features.
With parametric modeling, we are no longer limited to using only the predefined basic solid shapes. It is also a good practice to create features that are parallel to the manufacturing process required for the design. In 123D Design, the CSG concept can be used as a planning tool to determine the number of features that are needed to construct the model. Leaf 1 Leaf 2 Terminal branches Result ROOT UnionĤ 3-4 Intro to Solid Modeling with 123D Design The Locator Design The CSG concept is one of the important building blocks for feature-based modeling. We can make modifications at the appropriate links in the binary tree and re-link the rest of the history tree without building a new model. This provides a convenient way to modify the model. By keeping track of the history, the solid model can be rebuilt by re-linking through the binary tree. The binary tree is an effective way to keep track of the history of the resulting solid. In a binary tree, the terminal branches (leaves) are the various primitives that are linked together to make the final solid object (the root). The resulting solid can be easily represented by what is called a binary tree. The INTERSECT operation keeps only the volume common to both solid objects.ģ Intro to Solid Modeling with 123D Design 3-3 Binary Tree The CSG is also referred to as the method used to store a solid model in the database. The CUT operation subtracts the volume of one solid object from the other solid object. The JOIN operation combines the two volumes included in the different solids into a single solid. There are three basic Boolean operations: JOIN (Union), CUT (Difference), and INTERSECT. Two solid objects can be combined into one object in various ways using operations known as Boolean operations. The basic primitive solid set typically includes Rectangular-prism (Block), Cylinder, Cone, Sphere, and Torus (Tube).
CSG describes the solid model as combinations of basic three-dimensional shapes (primitive solids). In the 1980s, one of the main advancements in solid modeling was the development of the Constructive Solid Geometry (CSG) method. Direct-modeling makes things remarkably easy for exploring design ideas.

The software can be downloaded at 123D Design is a very powerful parametric modeling software but it is also a directmodeling software, which means that the users have access to editing, through drag and drop, faces and edges of the solid model. The created 3D objects can then be 3D printed or manufactured with CNC, laser cutters and etc. 2 3-2 Intro to Solid Modeling with 123D Design Introduction 123D Design is a powerful, easy and user-friendly 3D modeling software that can be used to create amazing and complex objects.
