Tips and skills to help you resolve headache problems in drafting.

Download the routine file, extract it if it is a zip file.
Use command "APPLOAD" in AutoCAD to load the vlx file.
Enter respective command in the command line to use it. In most cases the command name is the same as the vlx file name. But sometimes there are more than one commands in a vlx file. You can find the detail of all available commands in the individual introduction webpage of the routine on the left column under "HOME".
Add the vlx file to your "Startup Suite" can load it automatically when you open a new drawing.
Before you get the free registration code, you can try it as a trail version. Most trail version have the same function as registered version, but there are some pop-up dialogue boxes as registration process and "Cards for orphans" project introduction. Some trail versions have limited functions. Simply email us your Serial Number shown in the Registration dialogue box and we will send you FREE Registration Code as soon as possible. Once registered, there will be no more registration reminding dialogue boxes.
