The HVAC Window can be used in either a Full or Brief format by selecting Style > Use Full Form or Style > Use Brief Form from the HVAC Defaults window.
Both the formats perform the same functions except the Full format has an additional option, Plane Positioning.
For details on the functions common to both forms, see 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).
You can 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): You can use the cursor to pick a new position in the 3D View. Before doing so, 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): You will be prompted to identify design ppoint to position the origin of the CE at a chosen P-point in the 3D graphical view, P-Points are described in the Getting Started with Marine and.Basic Features of the Catalog |
|
ID Element |
Specify the method of identification of a point through which the plane is constructed (p-arrive): You will be prompted 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. |
