AutoCAD Tips And Tricks.
For me, not 100% perfect solution. Even if someone has a piece of paper, you can always scan it and put it in AutoCAD, which could overwrite your logo and write your name.
However, there are several ways that could be difficult for people who want to use your file.
Do as PDF
If the goal is to protect your information off the option to preserve the layers. It’s quick and easy way. There are ways to return a PDF to DWG with converters, but lost styles, settings and everything appears as lines.
By using a password-protected DWG or DWF
Since version 2004, we have the option to password protect our DWG file. This is done through the options in save as. This is a solution if the goal is that no one can open the files. If the file is sent to another person and it just looks it is not appropriate because it should still give him the password to open the file.
As destroy it with DWG-explode and purge
One way is to file before sending it to “ruin” to explode and all objects to break lines. Then purge stored blocks are cleared from memory and styles. This yields a file that looks like the original, but it is difficult, almost impossible to work.
Using external software
Some external programs such as CADVault can protect our files read-only, but they have additional software to be purchased and installed. I’m not a fan of using external software, it will never guarantee that no “grease” my file and what happens when a new version of AutoCAD or the company simply decided to stop development of it’s software.
More clever way
As I said there is no 100% protection, but here’s a way that will suffer your “thief” quite while decode what you have done. Piece is made of a block is placed on command and MINSERT injected with options “2 rows”, “2 columns” and the distance “0″.
