Autocad 3d Drawing Tutorial
We have taken a good time lately working on mastering the basics in AutoCAD, and with it, you must be able by now to draft all basic shapes using AutoCAD.
As you must have noticed from our past experience, learning AutoCAD goes first with understanding what the environment is made of, How to draw basic shapes, and finally how to combine all the basics to create complex designs. AutoCAD 3D tutorials: AutoCAD 3D how-to tutorials. Dec 21, 2011 This is a basic beginner tutorial of AutoCAD 3D. This tutorial shows how to creates a 3D object using AutoCAD 3D commands. AutoCAD Commands used in this tutorial are: UCSICON, SE Isometric, Line.
For Further Thought: We live in a 3D world, yet for centuries have drawn the world around us in 2D. There is still a place for 2D drafting, but if you are serious about learning AutoCAD, you should know how to draft in 3D. 3D modeling opens up new roads that just aren't possible in 2D drafting. May 24, 2019 AutoCAD is a powerful tool to create 2D and 3D objects, like architectural floorplans and constructions or engineering projects. It also can generate files for 3D printing. If you want to start this AutoCAD tutorial for beginners, you should be able to spare roughly two hours for it. Here is the object in 3D along with its 2D drawing which we will learn to model in this post. I recommend you to switch to drafting and annotation workspace for this drawing, you can also download CAD files for this tutorial here. Related: AutoCAD 2D and 3D practice drawings Step 1. Open the Workspaces drop-down list on the Quick Access toolbar, or click the Workspace Switching button on the status bar and then choose 3D Modeling. Toolbars, palettes, and Ribbon panels flash on and off, and soon AutoCAD settles down to display the Ribbon, as configured for the 3D Modeling workspace with a few additional panels.

AutoCAD 3D features
Before diving into creating your first 3D drawing in AutoCAD, I would like to throw the following.
AutoCAD is primarily for generating 2d sketches. It does have some ability to visualize those 2d sketches in 3d, and even to make 3d objects, but it’s primarily built around a flat, sketch-based workflow. If your invention is fundamentally two-dimensional, or made of trivially interlocking 2d parts, AutoCAD might be the right thing.
Inventor is for 3d product design. It’s a professional piece of software and takes quite a bit of time to learn, but that’s also true of its direct competitors. It’s currently Autodesk’s most powerful tool for mechanical design. I can’t give you a coherent feature comparison to SolidWorks or Creo because I don’t know them well enough; I do know that SolidWorks is more popular. Inventor is second, I think.
We do have a fairly new product called Fusion 360. It’s built on the same modeling kernel as Inventor, and has better free form modeling. It’s designed to be an all-in-one package for product design by hobbyists and small businesses. We focused on making the user interface as easy to learn as possible. It’s still quite a new product, and gets updates every few months, partly based on user feedback from its forum. A major advantage is that it’s free until you start making money with it, and even after that it’s pretty inexpensive.

No need to elaborate further, but be aware that there are some industries (like Structural Design, Civil engineering) where AutoCAD is the preferred CAD software for 3D creation.
Surface Modeling and Solid Modeling
While talking about AutoCAD Drawing and CAD, it is important to know the difference between Surface Modeling and Solid Modeling.
Surface modeling CAD (Blender, Sketchup, Rhino, Maya) deals with manipulating the curves and surfaces of a model. It’s more free form and generally done by clicking and dragging the surface/curves around to your liking. It’s ideal for architects, jewelry design, or anything you want done aesthetically.
Solid modeling CAD (Solidworks, Inventor, ProE, SolidEdge, GeoMagic) deals with adding dimensions and constraints to a 3d model. It is “parametric” meaning you can define the shape and later edit. This is very essential for engineers since design changes are always happening. Great for mechanical parts that require constant iterations. Some solid modeling CAD can perform surface modeling but it’s a nightmare.

Before fully diving into this, you should make sure all tabs are activated. (Right click to show the menu)
Creating a Cylinder
To create a cylinder
- Click on Cylinder
- Specify the center of the base
- Specify base radius
- Specify the height of the cylinder
Other routes you can use to create a cylinder are the following.
Using the EXTRUDE command
- Create a Circle
- Use the extrude command to obtain the cylinder
To do that
- Create a circle the way we learned
- Type EXTRUDE and Press ENTER
- Select the circle and Press ENTER
- Specify the height of extrusion

Using the REVOLVE command
- Create a rectangle
- Use the REVOLVE command to obtain the cylinder
To do that
- Create a rectangle using the RECTANGLE command
- Type REVOLVE and Press ENTER
- Select the rectangle and Press ENTER
- Select one of the ends of the red line shown on the image above
- Select the second end
- and Press ENTER
Using this method, you can at the last step decide not to close the cylinder, meaning you will have to enter an angle value less than 360 before pressing ENTER.

Create the last piece of that elbow
Simply create a triangle and extrude it. (use the POLYLINE command to create the rectangle). You can as well use the WEDGE command to create it.
We have pretty much created all basic 3D objects we need, now we need create copies, rotate them and assemble everything.
We have seen quite a number of new techniques here today, We will be coming back for the second part of this, where we will deal with some commands like UCS, UNION, SUBTRACT, INTERSECT and show you how to assemble the whole to create our final design.
