Settings, functions and parameters
Properties
/ 
Length / Width / Height
The fields show the dimensions of the object or expect you to enter the desired values.
The input is blocked,
if the size is determined by the selected product.
The input is enabled,
when a size = 0 in the settings of the selected product.
The Height parameter is only relevant for objects in rectangular ducts.
| Duct | Effect |
|---|---|
| Circular |
The object is cylindrical. The Width value corresponds to the diameter.
|
| Rectangular |
The object is cuboid.

The symbol is passed to an end. |
Rotation
Rotation of the object in degrees (°) around the central axis of the ventilation duct. A change in the value in the positive direction causes a rotation to the right (in the drawing direction of the ventilation duct).
Angle to X-axis
The setting only applies to objects in vertical duct segments. The rotation of the component is defined as angle. At an angle=0, the object is rotated to the right and corresponds to the position of the X-axis. A positive rotation causes the component to rotate counter clockwise.
Product
