AutoCAD 3D Commands
AutoCAD is a three-dimensional CAD software which is used by commercially across the world. Developed by Autodesk in the year 1982. AutoCAD is also available as a mobile and web app which is marketed as AutoCAD 360. AutoCAD offers an exclusive range of commands and functions both for 3D and 2D modeling and drawing with an amazing set of tools. 3D is all about the third Z coordinate. While working in 2D the user only cares for the X and Y axis and most of the time coordinates are not used. Whereas, while working with 3D the user uses all the coordinates which can even make their work quite easier.
Why do I need a 3D?
Today, Technology has made it possible to link our imagination a bit closer to the reality and it can be done by 3D modeling, printing, rendering and more. There is a huge number of software available in the market that offers the users to bring their imagination into reality. Some of the software is freeware while some are priced. With every update and with continuous new discoveries, people are more attracted towards the technology that is offering them to make and create vivid designs. The need for 3D is a necessary part of the designing world. Without it, the design almost looks like a sketch. Moreover, 3D is a boost for all the interior designers, architects who can design life-like models of any building, office or any exterior with some interiors as well like furniture, walls, show pieces and more.
A process of creating a mathematical representation of any surface of an object in three dimensions by using special software is called 3D modeling. A 3D model can even be represented as a two-dimensional image by using the 3D rendering process. The user can also create 3D models physically using 3D printers. There is a lot of software that is used to create 3D models like AutoCAD, MAX, MAYA, and many more.
3D models are high in demand with the game developers as well. Some computer games use already rendered images of 3D models which are known as sprites. This helps the designer to view the model in all directions and they can make sure that the object created is like the original one. Presently, 3D models are also used by the movie industry, they use them as objects for animated and real-life pictures. Also, since a lot VFX are used in movies and gaming industry 3D models, renders and effects are most commonly used. The medical industry also uses 3D models of organs.
Some of the benefits of 3D modeling are: –
- Using 3D models, users can get a more evocative design and they can even see the virtual images of their projects.
- An architectural 3D model is much more interesting and realistic than a 2D model.
- The experience that a 3D model gives is much more compelling and satisfying to the user than viewing a 2D drawing. The user can see the impact of all the minor and major changes made in a 3D model. This also aids in better finishing of the designs, without wasting time and money.
- 3D models are an amazing advantage to interior designers as they get to create and then modify 3D interior as well as exterior as per their need and choice.
- In a 3D design, the user gets to know the physical dimensions of the objects and its distance in relation with other objects in the total layout. This feature helps enormously to see and modify arrangements of objects based on their sizes.
- For best results, some artists use a mixture of 3D modeling followed by editing the 2D computer-rendered images from the 3D model.
Top AutoCAD 3D Commands:
Let us look at the top AutoCAD 3D commands which are as follows:
Location: Draw > Modeling > Revolve
This AutoCAD 3D command creates a 3D solid by revolving a 2D object around an axis.
4.5 (960 ratings)
Location: Draw > Modeling > Extrude
This AutoCAD 3D Extrude command allows the user to create a 3D object by extruding a 2D face along a line or path. For example, A cylinder can be created by selecting a 2D circle and extruding it along with a path.
Location: Draw > Modeling > Sweep
This command helps the user to extrude the 2D objects without the 2D face being orthogonal to the beginning of the path.
Location: Modify > Solids Editing > Union
This AutoCAD 3D command allows the user to combine two objects converting into one single object.
Location: Modify > Solids Editing > Subtract
This command is opposite to the union command; this command works when there is a common area in both the objects. Then this command subtracts the object A from the object B.
Location: Modify > Solid Editing > Intersect
With this AutoCAD 3D command the user is left with the area that is common to both the objects.
3D Drawing Tools
AutoCAD is primarily used for generating 2D sketches. While it is possible to create 3D objects, AutoCAD is built around a flat, sketch-based interface. There is a wide range of pre-defined 3D objects in AutoCAD. These objects are cylinders, spheres and wedges and many more. But then users use 2D objects and modify them using the 3D commands accordingly. So, AutoCAD 3D commands like Extrude, Sweep, Revolve, Union are used by the users.
Also, the user must know the importance of Viewport feature if they are working on 3D Models. The viewport command allows the user to split the drawing area into different windows to project multiple views of the model. These include the top, front, left/right views of the object. This feature works great for the user and helps them to observe the model from different aspects.
Conclusion – AutoCAD 3D Commands
AutoCAD 3D Commands is a lengthy and challenging software for the beginners. Yet it is extremely useful and has a lot of benefits. It is a powerful CAD software, which is used for architectural design and mechanical engineering. It has one of the best toolboxes and functions to support 2D drawings. However, when it comes to 3D design, it is impressive, with its 3D rendering feature that gives stunning and vivid outputs.
