Be sure to read the download page and the readme file (English only).
This Service Pack can be applied to AutoCAD 2015 and AutoCAD LT 2015 installed as a standalone application as well as AutoCAD 2015 and AutoCAD LT 2015 installed from the following suites or bundled products.
Have you even run into a problem in AutoCAD (or a vertical such as Civil 3D), that you can't figure out such as a drawing behaving strange, commands not acting right, commands not working, or maybe even the whole application just won't launch? One of the first things I would suggest is to have someone new log onto your machine and launch AutoCAD under their Windows profile, essentially creating a new "AutoCAD Windows Profile". If the problem goes away when you do this, then it is probably some error or corruption in your own "AutoCAD Windows Profile". Read more about Reset your AutoCAD Windows Profile
The AutoCAD linetype syntax is pretty simple. Referring back to Part 1, recall the linetype definition that I copied, edited, and named MY-DASHED.
Looking at the definition, the first item is an asterisk, followed by the name of the linetype, then a short description, and finally an ASCII representation of the linetype. This last part is totally up to you, just get it as close as you can. Look at some of the other linetypes as a reference. Read more about AutoCAD Linetypes - Part 2
So where do AutoCAD linetypes come from? When you start up AutoCAD and start drawing some geometry and decide to change the linetype to something other than Continuous, where did they come from? How did they get there? How can you change them or add more?
To start with, there are two types of linetypes, simple and complex; both are stored in the DWG file. Simple linetypes are composed of line segments and spaces (or gaps) only. Examples include the HIDDEN, DASHDOT, and PHANTOM linetypes, as shown below. Simple linetypes are fully contained in the DWG file. If you send a DWG file to someone else, you do not have to send any external files along also in order for the simple linetypes to display correctly.

I wonder how many people are familiar with this macro? I am pretty sure it used to be in the stock OOTB AutoCAD menus a long time ago, maybe on the screen menu?
The macro I'm talking about is one that executes the ERASE command with the single object selection, and then repeats. This can be very useful if you are working in a congested area and you need to erase some objects, and where a window or crossing selection is too risky because you might erase something by mistake.
The leading asterisk causes the macro to repeat, and the single option after the erase command starts means that it will let you select one object and immediately delete it. This should work in both AutoCAD and AutoCAD LT. Give it a try.
Essentially, the SAVE command is supposed to save the current drawing to a different name but without changing to the new drawing. So if you are working on A.DWG and you run the SAVE command and give it the name B.DWG, then B.DWG is created as a copy of A.DWG, but you are still working on A.DWG.
AutoCAD LT Technical Marketing Manager, Kate Morrical confirmed that this change is by design and not a bug, and told me that this was actually introduced in AutoCAD LT 2011. I found it strange that this change was not implemented in AutoCAD at the same time. This could not be a wishlist item, and I do not understand what is gained by removing existing functionality.
