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 steps: 1. Create an [...] 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 view [...] 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 sure [...] 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.” One of the new features in AutoCAD 2008 is data extraction. This might make you think of block attributes and data connectivity, but it combines features of both. It’s both simple and powerful. You start with the new DATAEXTRACTION command, or by starting the TABLE command and choosing the From Object Data in the [...] When you click either the Pan Realtime or Zoom Realtime button on the Standard toolbar, you can drag to pan or zoom. At this time, you’re in a special mode and you need to press Esc or Enter to return to the command line. If you don’t like the result or just want [...] A region is an interesting type of AutoCAD object. You can think of it as a 2D surface. Regions are always closed and they look like polylines, but AutoCAD can do some interesting things with regions, such as: Calculate centroid, moments of inertia, and products of inertia Tharakesh of HOPE Technologies Ltd. in Mumbai, India submitted the following tip. When using the 3DORBIT command, the portion that you want to see may be hidden by another portion. In that case, before invoking the 3DORBIT command, select the object in which you are interested. Then 3DORBIT displays only the selected object. It’s cool! This [...] |
