Some of these may have already been posted...well I know they were a few months ago...I haven't been in here for a while.
1. Page Setups
Create a drawing called PageSetups.dwg and in it, go to File > Page Setup...
Add a page setup for each print job you could possibly have. For example,
A-Mono-Landscape
B-Mono-Landscape
D-Mono-Landscape
B-Colour-PDF-Landscape
...and so on...
Save PageSetups.dwg in your AutoCAD/Support directory and try the macro below.
It makes printing and plotting in AutoCAD 2k and later a snap!
^C^C.-PSETUPIN "PageSetups.dwg" "*"
2. Insert Block with Dialog Box
Opens a file dialog box for you to select a block to insert. (The reason for this is to give you a preview...it almost acts as a slide library that way)
^C^C(setq BlockName(getfiled "Select drawing file" "C:/DRAWINGS/" "DWG" 0))(command "-INSERT" BlockName)
3. Windows Explorer
To open Windows Explorer in the folder containing the current drawing open in AutoCAD:
^C^C(COMMAND ".BROWSER" (GETVAR "DWGPREFIX"))
4. Change Text Width
CHtext.lsp must be loaded for this macro to function properly.
^C^CCHT;\\;W;\;
5. Delete Nul Entities and Purge Them
Deletes Nul Entities - Such as empty text strings and empty blocks - Once deleted, blocks must be purged from drawing. W:\Menus\LSP\Delnul.lsp must be apploaded for this function to work.
^C^CDELNUL;PURGE;
6. (a)Open ACAD.PGP & (b)Reinitialize it
(a) Opens acad.pgp in Notepad so you can add or change more of your key-ins.
^C^C^P(command"notepad"(findfile"acad.pgp")) ^P
(b) After you make a change to the acad.pgp file, it must be reinitialized for the changes to take place.
^C^C_RE-INIT 16
7. Global Attribute Edit
The standard AutoCAD attedit command with a bit of it done for you…
