This program can be used by mechanical engineers and draftsmen as well as those working in the field of HVAC system.


The first radio buttons 1.0 and 1000.0 relate to the scale of your drawing. If you have units of 1.0 equal to one meter, then go with the first <default> setting. If you have units of 1000.0 equal to one meter, then go with the second radio button. Furthermore, this option will allow the program to create the HVAC Diffusers as per the above-mentioned scale.


The Program has many sizes of HVAC Diffusers that are used in the field of HVAC, starting from 15x15 up to 60x60 which the user can roll down. The first popup menu allows the user to choose the right size for their needs. The second popup menu will follow the same size that has been chosen from a Supply popup menu and this technique is just to make the program more user friendly and save time and efforts while picking or setting the options.


Also, the user has the ability to specify the right Layer Name for both Supply & Return Diffusers from the popup menus that related to each type. 

Finally, the program has also a very powerful option via specifying which Diffusers type to start with, Supply or Return from the popup menu. 


You can use this program for 100 times. After the expiry of the program, you will receive a dialog showing the serial number (codes) of your PC and my Email ID. 


NOTE: you can get the full version of the program before the program expires by pressing the Activate button that is available in the same dialog of the program.


Please send me an email including the serial number after the payment done. Once I receive the payment then, I will send you the full version of the program.
