The 3D window displays the locations and dimensions of Stormwater Controls (SWCs), Junctions, Connections, Surface Data, and Overland Flows in three dimensions.
Notional Connections are displayed simply as a line between the exceedance / cover elevation of the connected junctions / SWCs.
Simple Junctions are displayed as a translucent sphere. The size and height of this sphere is determined by the incoming and outgoing connections.
Bypass Connections are displayed identically to other connections in 3D, unlike on Plan.
Inlets and Outlets are not displayed in 3D.
Underdrains are not displayed in 3D on SWCs with custom outlines.
Stormwater Controls that contain multiple smaller structures (Cellular Storage, Chambers, Dry Well) are rendered as cylinders, cuboids or prisms, rather than as a collection of smaller structures, if the position of each smaller structure cannot be determined.
To avoid a visual error known as Z fighting, when water dimensions are set to a dimension of an object, a small offset is applied. Because offset is always applied at the bottom and sides of objects, the volume of the displayed water is not exact. The water elevation is kept exact where possible (see Specific Implications column in the table below).
In the following table, an object is labelled as not flooding if the water elevation obtained from analysis can never be greater than the objects cover / crown.
Top | Floods | Flooded area | Example | Where is offset added? | Specific Implications |
Open | No | - | Rectangular channel | Bottom and side edges only. The top of the water is exactly the elevation obtained from analysis. |
|
Open | Yes | Matches top area | Pond | Bottom and side edges only. The top of the water is exactly the elevation obtained from analysis. | |
Closed | No | - | Pipe | Top, bottom and side edges. |
Water elevation is not exact, only the water shape, i.e., the water in a pipe is only a completed cylinder when the water elevation matches the diameter of the pipe, but this cylinder is larger than the pipe. |
Closed | Yes | Matches top area | Porous Paving | Bottom and side edges only. The top of the water is exactly the elevation obtained from analysis. |
If the water elevation is very close to the top of the closed object, there will be Z fighting. |
Closed | Yes | Set area | Manhole (unless sealed) | Bottom and side edges of the non-flooded area only. The top of the water is exactly the elevation obtained from analysis, regardless of flooding. If the object is flooding, the flooded area is exactly the set area. |
If the water elevation is very close to the top of the closed object, there will be Z fighting. |
Video controls appear on the form when results have been generated, which allows you to view their water elevation animation. If more than the result form is open, the water elevation animation will be synchronized between them, as well as any open profile forms and SWC item results forms. The same video controls also appear on the Status Bar .
The camera points at a focal point in the center of the screen, which can be controlled in the following ways:
The following keyboard and mouse inputs can be used to control the camera in the 3D window.
Action | Keyboard Input | Mouse Input |
Move Forward | W / Up Arrow |
Holding the middle-mouse button and moving the mouse forward or backwards will move will move the design in the direction of the mouse movement. |
Move Backwards | S / Down Arrow | |
Move Left | A / Left arrow | Holding the middle-mouse button or left mouse button and moving the mouse left or right will move will move the design in the direction of the mouse movement. |
Move Right | D / Right Arrow | |
Move Up | E / Page Up |
Holding the left-mouse button and moving the mouse will move the design up when the mouse is moved forward and down when moved backwards. |
Move Down | Q / Page Down | |
Faster Movement | Hold Left Shift | Not Applicable |
Slower Movement | Hold Left Shift and Left Control | |
Turn Up | I |
Holding the right-mouse button and moving the mouse will rotate the camera in the direction of the mouse movement. |
Turn Down | K | |
Turn Left | J | |
Turn Right | L | |
Zoom In | + | Scrolling the mouse wheel forward and backward will move the camera in towards the focal point and out away from the focal point respectively. |
Zoom Out | - |
The directional arrow on the compass control will show you which direction the camera is pointing.
Clicking on one of the cardinal directions (N, E, S or W) will move the camera to that side of the focal point. e.g. Clicking N will move the camera north of the current focal point, and point the camera south.
The and buttons will zoom the camera in and out, moving the camera towards and away from the camera respectively.
Pressing the Extents button will update the view to the full site extents.
Settings specific to 3D are available under 3D sections in both the Tree View and Display Settings. There is a 3D node in the tree view underneath the surface node, which can be used to quickly update 3D surface settings.
The following settings are shared with other areas of the software.
The shape representing an object in the 3D window is not always identical to the shape used in analysis. Analysis is performed on either an equivalent or simpler geometry. See the following pages for more information on analysis: Analysis, Analysis of Junctions and Connections, Analysis of Stormwater Controls.
If there are problems in the 3D view such as the visual error known as Z-fighting or other graphical issues, the problem may be solved by switching from the on-board Video Card to the dedicated Video Card (if available). See the instructions below on how to swap for both Nvidia and AMD Video Cards:
