This program allows you to draw the HVAC duct works dynamically and professionally, regardless of the current drawing's units. Furthermore lots of fittings are included within this program, such as Duct <Straight>, 3Points Duct with Elbows, either 45 or 90 Degs, Elbows [30,45,60,90], Taper, Tee, Reducer, Offset and Undo, allowing the user to undo the last drawn objects which means to undo the last process.


Also, the program uses specific layers for specific systems like Air-conditioning, Fresh Air and Exhaust air systems with respect to Color, LineType and LineWeight. This allows them to be by layer regardless of the settings of the current layer.


The program allows the user to change the units of the text of Duct size and allows the user to add a label for the air flow rate.


After you have downloaded the trail app, if you want to purchase the full version of the app, use the command SERIAL to obtain the machine codes in the command line and send an email to us. We shall get back to you with more details on how to get the full version.

Finally, the Program should work for approximately 450 times. The time starts at the first moment you run the program on your system. If you have used the program for one month and it expires then this means you have used all the benefits of the program. If you have used the program for only a few times and left it for more than one month from the moment you first ran the program then it will be expire since it did exceeded 30 days.

About This Version

Version 4.1.0, 12/4/2017
This version is released to allow users to specify their desired LineType with the system layer they intend to use by pressing the right hand side button ( ... ) next to each system layer. A new dialog should appear now and only the required linetype name can be selected by the user. After accepting the inputs the button that relates to system layer should be activated for user's for the next step. NOTE: If the button ( ...) is deactivated when the related radio button is checked out then this means the related Layer Name is already created and existed in current opened drawing.
