Have you ever wanted to run a script file on one or more drawings, without having to use the overhead of the entire AutoCAD application? Starting with AutoCAD 2013, you can. AutoCAD 2013 comes with a tiny application named AcCoreConsole.exe. (The AutoCAD Core Console). This is basically a stripped down version of the AutoCAD engine without the graphics screen.

There does not seem to be an option for changing text portions of dates (such as the name of the month) to UPPERCASE (or lowercase) using the Field command dialog box. All of the examples shown are in First capital.
However, if you explore other fields where there are options to change the case, you can see that setting a field to UPPERCASE simply adds some code to the end of the field like this: "%tc1". Read more about Changing the case of date fields
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 LENGTHEN command has been around for over 18 years, it was introduced with Release 13 in November of 1994. Yet, I still see many instances where it is ignored and some other method is used in its place. So what can you do with the LENGTHEN command? Let's look at the 4 options, or ways it can work.

There is a bug in Civil 3D 2013 that occurs when you try to sort the parcels in the Prospector. Normally, you can click on a column header and sort the table by that column, but if you do this with Parcels, the entire list goes away. Closing and restarting Civil 3D does not help, and neither does rebooting the entire machine. Here is a before and after screen shot. Notice the little sort arrow in the Name header does not appear in the Before shot, but it does appear after clicking on the Name header in the After shot. Read more about Civil 3D Parcel Sorting
