Automatic positioning of the diffusers
The software permits the automatic placement of diffusers. This feature is extremely important for large areas. The user specifies the distances along the X and Y axis (matrix definition) and the software will draw the diffuser automatically. The elevation of the diffusers is specified on a dedicated navigator tool bar and referres to the elevation of the ceiling of the current building floor.

A single diffuser drawing is allowed as well; in this case the user will specify position X, Y through the mouse pointer while the elevation can be fixed on the navigator tool bar. Any type of OSNAP is usable and helpful to place the diffuser accurately. Once the diffuser has been placed, the program sizes the diffuser according to the room’s flow rate and the diffuser models available in the database. When several diffusers are placed in the same room, the program automatically splits the total flow rate between the diffusers in order to avoid any over sizing.

The user selects the terminal category to be placed while the software decides the diffuser size based on the required air flow in the room.

Duct Drawing
There are no restrictions on drawing when designing a duct system. The user is free to design any part of the network in any point of the space without being forced to follow any predefined hierarchy.
The logical sequence of each part of the net is continuously updated this keeps the distribution or air direction coherent. The user can change the direction of air flow at any time using a dedicated command.

The intersection between two or more ducts is automatically executed by inserting the correct type of fitting for example: a tee, tee branch or cross.

The automatic rotation of the coordinate system (UCS) allows the sloped duct to be drawn easily. This feature allows the user to draw branches contained in a sloped plane without twisting. When a twist occurs the transition fitting will be automatically positioned.
A furnished database of fittings and duct-components is already included in the program and allows the user to view the network realistically.

Automatic diffuser connection
The connection between a diffuser and the feeding duct can be executed automatically by the software. This connection can be specified while the diffuser is being drawn. After the diffusers are placed in the project the OSNAP on the duct is sufficient to create the connection. The user can manually specify the diffusers and supplying ducts or have Mc4Duct software design the connection lines automatically.

Generation of 3D modelling
3D modelling is created automatically by the software while the user is drawing the ducts. The default dimensions, if not locked by the user, will be modified by the calculation in order to meet the specified design conditions. The user can also set the position of the duct to avoid interferences with other systems.

Output
The software provides detailed calculation reports as well as a Bills
