  • AutoCAD Centerline
    We’re excited to share a new Have You Tried article this month.  It’s all about center marks and centerlines.  Have you ever needed to mark the center of an arc or circle? How about needing to draw a line at the apparent midpoint between two lines or polylines. I’m sure you have. There are two […]

  • MText Feature
    For the Have You Tried this month, let’s take a deep dive into formatting a multiline text object (also referred to as MText). Text is one of the most common annotations that you add to a drawing. Creating text in AutoCAD might be intuitive, but editing and formatting text can take time. In this Have You Tried, […]

  • Have You Tried Window Fence Lasso Feature
    For the Have You Tried this month, we have some great techniques for selecting and deselecting objects. Window and crossing window are great selection methods in most cases, but for larger, more complex drawings it might be helpful to use other methods like fence or lasso. And after objects are selected, maybe there are some […]

  • AutoCAD Wipeouts and Masks Feature
    For the Have You Tried this month, we have some great techniques for removing the visual clutter from complex drawings that have lots of overlapping objects. Overlapping objects and annotation can decrease readability while at the same time increase the chances for confusion of a design. Creating wipeouts and using masks to hide parts of the […]

  • Have You Tried February Purge Overkill
    For the Have You Tried this month, we’re going to take a look at removing unused named objects and overlapping geometry to keep our drawings clean and tidy, and even possibly keep the file size down along the way. Unused named objects can be block definitions, layers, or linetypes that are no longer used or […]

  • AutoCAD view with name
    For this Have You Tried, we’re going to give names to AutoCAD views. A view consists of a specific magnification, location, and orientation that you can save and assign a name. This is called a named view. Named views make it easy to return to a specific view of the drawing at any time. Specific layer visibility […]

  • Accessing Data from Clipboard in AutoCAD
    This month’s Have You Tried is all about copying data into AutoCAD using the clipboard. The clipboard can be a convenient way to create a table from a spreadsheet that contains a door and window schedule. In addition, the clipboard can be used to copy objects and geometry between drawings and layouts, or outside of […]

  • Action Macro Feature Image
    We have an amazing time-saver for you this month: action macros. If you use AutoCAD commands and system variables, you can record action macros. And the best part about using action macros is there’s no programming knowledge needed. All you need is the AutoCAD knowledge you already have. Imagine creating an action macro to simplify […]
