Please be cautious if you are intending to upgrade to the new MAC OS and are using AutoCAD for MAC. AutoCAD for Mac 2015 is compatible with Mac OSX Yosemite (10.10). AutoCAD for Mac versions 2014 and earlier currently are not compatible with Mac OSX Yosemite (10.10). These versions may launch, but will not operate properly and damage to your project data could occur.
Please take a look at the link below for further information.
I'd like to invite you to join us for our next AutoCAD/AutoCAD LT Hangout Session. This week we will cover the fundamentals of working with blocks! If you have been using blocks but only have a minor understanding of defining a block or you wish to just wish to learn more, then join us! For more information check out
Are you noticing that in AutoCAD 2015, the linetypes that you have set on your hatch are showing as continuous? If this is the case, you may need to change the HPLINETYPE variable. By default, this variable is off to save on system resources. But one of the side effects of it being off is that hatch linetypes will not be displayed. Turn the HPLINETYPE variable to 1, and all should show correctly again.
When running AutoCAD for Mac 2013 or earlier as well as AutoCAD for Windows in a virtual machine on the high resolution retina display, the display may not appear as expected.
AutoCAD for Mac 2014 has added support for Retina Display. On Windows side, we are actively researching solutions not only for Virtual Machines on Mac, but also for newly exposed DPI options in Windows 8.1.
In the meantime if you are using a virtual machine i.e., Parallels desktop to run AutoCAD for Windows you may want to try the following solution to see if it helps:
Shut down your virtual machine
Go to Virtual machine menu > Configure... > Hardware > Video > uncheck Enable Retina display
The PURGE command in AutoCAD 2015 and Verticals will now purge dgn linetypes and orphaned dgn linetype data. This functionality cleans up non-essential data from DWG files that have become bloated while copying and pasting from DWGs containing DGN linetypes. Previously a Hotfix was necessary for AutoCAD 2012 as well as for AutoCAD 2013/2014 in order to remove these objects. In both cases the Hotfix required the user to use the NETLOAD command in order to load the DgnLsPurge.dll,once this .dll (Dynamic Link Library) was loaded the user had to use a separate command, DGNPURGE, which removed all unused DGN data. Unfortunately, the NETLOAD command is not available in AutoCAD LT so those users were not able to clean up their files as easily. AutoCAD LT 2015 user are now able to PURGE dgn linetypes as well.
There is a difference as to how the PURGE command removes DGN data; the hotfix's DGNPURGE command will always remove all unused dgn linetypes and orphaned dgn linetype data, giving the user no choice if they wish to keep some of the data in the file. The PURGE command in 2015 has a new "Automatically purge orphaned data" checkbox which, when checked, will remove all orphaned DGN linetype data, but it does not automatically remove all unused DGN linetypes. Full DGN linetypes are treated just like any other linetypes, the user must select which linetypes to remove. This make it possible for users that have DGN linetypes in their drawings which are not currently in use, to have the option to keep specific DGN linetypes in the drawing for future use.
Both the PURGE and -PURGE command support purging orphaned DGN linetype data as well as removing the DGN linetype data.
