The HVAC Window can be used in either a Full or Brief format. Both the formats perform the same functions except the Full format has an additional option, Plane Positioning. To switch between Full or Brief formats, right-click on the HVAC window and select either Use Full Form or Use Brief Form from the pop-up menu.
For further information on the functions common to both forms refer to HVAC Window.
Plane Positioning
The additional positioning aid to position elements defines a reference plane for use as a construction aid.
The plane is called the construction plane, the plane is defined in terms of its position (a point through which it passes) and its direction (the direction of a line normal to the plane).
Use this option to define the construction plane’s position and direction:
|
Plane Direction |
Define the direction of the normal to the plane: Input a direction. |
|
Cursor |
Specify the method of identification of a point through which the plane is constructed (p-arrive): Use the cursor to pick a new position in the 3D View. Before doing so you should reset the view to a Plan view. The first prompt Enter a 3-d position is used for the east and north coordinates. The view will then flip allowing you to pick a point to be used for the elevation of the element (Enter a 2nd point to define third coordinate). |
|
ID P-Point |
Specify the method of identification of a point through which the plane is constructed (p-arrive): A prompt to identify design ppoint to position the origin of the CE at a chosen P-point in the 3D graphical view is displayed, P-Points are described in the Getting Started with Plant and Basic Features of the Catalogue. |
|
ID Element |
Specify the method of identification of a point through which the plane is constructed (p-arrive): A prompt to identify element to position the origin of the CE at the location of the origin of a selected element in the 3D graphical view is displayed. |
