This is a fairly simple wheel with a center tube for an axle/pole, a rim, and 6 holes. You can create a 3D wheel like this entirely with cylinders! Watch this 9-minute video tutorial and follow along to create it from scratch yourself.
You’ll learn how to:
Create cylinders: Cylinders are an obvious choice for […]
An excellent (and old) feature of AutoCAD is that you can define your own coordinate system:
The location of 0,0 The direction of the X axis The direction of the Y axis
A custom UCS is a common aid for 3D drawing. For example, if you’re drawing a peaked roof of a house, it’s much […]
Spherical coordinates are a way of specifying coordinates in 3D. Mostly, you use them with the LINE command. They’re good for finding a coordinate that you might use in a solid or surface. (I cover cylindrical coordinates, which are similar, here.)
Spherical coordinates have the format distance<angle<angle. An example would be 6<40<20. The 3 parts […]
Cylindrical coordinates are a way of specifying coordinates in 3D. Mostly, you use them with the LINE command. They’re good for finding a coordinate that you might use in a solid or surface.
Cylindrical coordinates have the format distance<angle,distance. An example would be 6<40,4. The 3 parts of the coordinate are as follows:
First distance: […]
The VIEWBASE command, new for AutoCAD 2012, automates the process of creating 2D views of 3D models. This command creates 2D view objects, which are a little like viewports, but actually a completely separate type of object. In fact, when you display a layout, the first thing you do is delete the default viewport and […]
Starting with AutoCAD 2012, you can use the VIEWBASE command to quickly create 2D views of your 3D model. These views are called view objects. The command prompts you to create views based on the default 3D views, such as Top, Front, SE Isometric, etc. You can choose a shading style, as well. It’s quick […]
Bill Walker sent me the following tip.
Sometimes you need to cut out part of one 3D object to fit another object. For example, in tongue & grove construction, you need to cut out the groove to fit the tongue. You can make this process easy with an option of the INTERFERE command.
Follow these […]
When you work in 3D, you need ways to view your drawing quickly and effectively. Here are my best tips. What are yours? (Leave a comment!)
Transparent 3D Orbit: Shift + Mouse wheel. This is my all-time favorite 3D viewing tip. If you aren’t using this, you’re wasting time. It lets you easily drag the […]
AutoCAD’s surfaces have evolved over the years. First, you could add thickness to 2D objects. I’m not sure when that happened (let me know if you do), but it was in the mid-1980s, perhaps around Release 2.6. This is still the only type of 3D objects that AutoCAD LT can create.
Later (again, I’m not […]
Some people prefer to learn from video, so I’ve created a video of a tutorial that I created on drawing a 3D threaded bolt. The video is 9 minutes long. You can find the text version at “Draw a 3D threaded bolt.”
