It’s common to need to place a circle in the middle of a rectangle, especially in mechanical drawings. It’s easy to do using object snap tracking. Object snap tracking tracks the coordinates on object snaps and for this task, you need to track the midpoint of the rectangle’s sides. Here are the steps: Make sure that the [...] Hatching can sometimes be frustrating, so I’ve collected a few hatching tips together, including links to other tips. Think of the collection as your personal hatching helper. In case you don’t know, a hatch is a pattern of lines and dots that fills an enclosed area. Create user-defined hatch patterns When you choose a hatch pattern and apply [...] Tommy Holder submitted a different approach to creating fillets–one that includes drawing the lines. For the earlier routine, see “Reduce mouse clicks and increase productivity with AutoLISP.” Tommy’s approach is unique, I think. Instead of drawing the lines first, the AutoLISP routine prompts you for points, which are the endpoints of the lines. Here are the [...] Splines are mathematically-defined curves. They are an important basis for 3D modeling, but they are useful in 2D as well. Note: Splines were significantly updated in AutoCAD 2011. There are 2 methods for creating splines: Fit Points: You specify fit points, which are on the spline (by default). You probably know that after you execute an AutoCAD command, you can press Enter to repeat it. But it might be quicker to set a command to repeat automatically, if you know in advance that you’ll use it a number of times in a row. Some commands repeat automatically. In a sense, the LINE command does this, [...] You may have several drawings open at one time and want to switch between/among them. AutoCAD gives you several methods to do so. I can think of four. Use the Windows taskbar The Windows taskbar can show a separate button for each drawing. The system variable for this is, appropriately enough, TASKBAR. When set to 1, you’ll [...] You’re always creating styles — text, dimension, etc. — layers, and blocks. But when you open the Layer Properties Manager or any other list with these items, they are alphabetized. Especially if you’re sharing drawings with others who add their own styles, layers, and blocks, what can you do to make it easier to find [...] It’s common to have closed figures inside other closed figures in AutoCAD drawings. When you hatch these shapes, you can specify whether or not the inner figures are also hatched. This becomes most important when you have 3 closed figures, one inside the other. In fact, you have 3 options for islands. To set the options [...] Xrefs (external references) let you view another drawing within your current drawing without actually inserting that other drawing. Why use xrefs? Xrefs keep your drawing smaller. You can auto-fill data in an AutoCAD table like you can in an Excel spreadsheet. This makes it easy to copy data along a row or column and to automatically create incremental data, such as consecutive numbers. To auto-fill cell data, click in a cell that you’ve already filled with a value. Click and drag the [...] |
