Choose Joint

The Choose Joint window displays a selection of industry joints, choose from:

The Shape drop-down list by default will be set to the shape of the HVAC component being created. In this example the Choose Joint window has been opened from the Rectangular Straight window, so the Shape is set to Rectangular. The Shape can be changed to Circular or Flat Oval by clicking in the drop-down list and selecting the required Shape.

Note:
Changing the value will results in a different list of joints being displayed.

Using the Joint option buttons choose which end of the HVAC component the joint will be used for. By default Leave will be selected, but this can be changed to either Arrive or 3rd Joint.

In the case of a Rectangular Straight only the Leave and Arrive Joint is relevant as displayed in the diagram below:

The 3rd Joint would be the joint used for a third connecting end of a piece of HVAC such as a Rectangular Twin Bend Three Way as shown below:

After clicking the Arrive, Leave or 3rd Joint option button, choose a type of joint from the available list.

Click OK to close the Choose Joint window and return to the Straight window. The selected Joint type will be copied into the relevant input field of the Straight window.

For example if the Arrive option button was selected in the Choose Joint window,

the Arrjoint field of the Straight window will be populated with the selection.

After selecting the type of joint to use for the Arrjoint and Leajoint enter the Width Direction.

In the Width Direction specify the Axis that should be used E (East), N (North), U (Up), -E (negative East), -N (negative North) or -U (Negative Up).

In the Position list, select Connect or Unchanged:

• Click Connect (default when create is selected) - connects the piece of HVAC to the previous one.

• Click Unchanged (default when modify is selected) - positions the component at the co-ordinates 0.00.

  Note:
  Unchanged is usually used, when Modify is selected, it does not connect the component but positions it at 0.00, in effect in a floating position.

Click Defaults to clear all the dimensions currently in the Straight window and set them to the dimensions when the window was first opened.

Click Fit to orientate the piece of HVAC to automatically match the outlet (p-leave) of the previous piece of HVAC to the inlet (p-arrive) of the next piece.

Click OK to create the Straight element in the Design database and close the Straight window. The HVAC window is displayed.

Click Cancel to discard the changes and close the Straight window.
