I have seen this question a few times in person and on various forums. For at least one version prior to AutoCAD 2011, AutoCAD arcs included directional arrow grips on the ends that performed as Lengthen grips.
AutoCAD 2011 introduced multifunctional grips that allow for (you guessed it) multiple functions, and the arrows disappeared.
If you want to restore the arrow grips, you can set GRIPMULTIFUNCTIONAL to 0
If you work with scanned images in AutoCAD, have you ever wanted to perform OCR from right inside of AutoCAD? Raster Design includes this ability, and Raster Design is now included in many of the suites. Read more about OCR in AutoCAD
Here, we are going to add a custom paper size in AutoCAD. If you print to a Windows system printer, you can add the paper size to the system printer. In this tutorial, we are adding a custom paper size to a PC3 file, and in this particular case the built in printer DWF6 ePlot.pc3.
This is a new empty drawing and the default size for our layout is 8-1/2"x11" (dimensions were added manually to illustrate the paper size).
When making entity selections in AutoCAD, sometimes the results can be unexpected. You may select a hatch object and move it its associative boundary stays put, or you may erase a line and other geometry disappears with it. Situations like this can be controlled by a system varible named PICKSTYLE.
I have been recently running across AutoCAD DWG files that contain hundreds of non-purgable linetypes, some with strange names, some that appear to be nested in mysterious blocks, etc. With help from the Autodesk Forums and some independent research, I became pretty sure these were created by importing Microstation DGN files.
Does your AutoCAD recent file list work for you, or does it fill up with seemingly random .DST (sheet set) files instead of the last .DWG files that you worked on? The latter is documented all over the Autodesk forums, here is one such thread, dated back to 2008 (yes, it has been an issue for that long). In another thread, Jeff Mishler from Quux Software has provided a standalone application (at no cost) to help you manage your recent documents list.
AutoCAD WS is now AutoCAD 360. The online/cloud version of AutoCAD has seen over 12 million downloads and 11+ million registered users since it was introduced. Starting today AutoCAD 360 will feature some new tools and some new purchase options. The modile app version is available for iOS and Android smartphones/tablets at no cost, but there are new "Pro" versions available. AutoCAD 360 Pro gives you 25GB of online storage, a maximum supported file size of 30MB, the ability to create a new drawing, plus more advanced drawing and editing tools. AutoCAD 360 Pro will cost you $4.99 per month, or $49.99 per year. If you need even more online storage (100GB) and the ability to work with larger drawings (40MB), AutoCAD 360 Pro Plus is available for $99.99 a year.
With AutoCAD WS currently installed, all you need to do is update the app and you will be ready to go with AutoCAD 360. I've included some screen shots of the free version below.
