Examining the 3D model

(Available in XT Pro)

Default UI Menu: View/Camera/Camera Turn, View/Camera/Camera Slide

Ribbon UI Menu:

img

Incremental controls for adjusting the camera, and therefore your view of the model. As the camera moves through space, the visible objects will seem to move in the opposite direction of the camera motion. These commands can be accessed via the Camera toolbar. You can also display the Camera Tools toolbar by right-clicking in any toolbar area and selecting Camera Tools.

img

Camera Turn Up: Turns the camera up.

Camera Turn Down: Turns the camera down.

Camera Turn Right: Turns the camera to the right.

Camera Turn Left: Turns the camera to the left.

Camera Rotate Right: Rolls the camera clockwise.

Camera Rotate Left: Rolls the camera counter-clockwise.

Camera Up: Moves the camera up.

Camera Down: Moves the camera down.

Camera Right: Moves the camera to the right.

Camera Left: Moves the camera to the left.

Camera Objects

(Available in XT Pro)

Default UI Menu: View/Camera/Insert Camera

Ribbon UI Menu:

img

Camera objects are used to create and save views with specific parameters. The view for each camera object can be displayed in a separate window. Each new camera is assigned a name by default (Camera 1, Camera 2, etc.) but this name can be changed. You can display the Camera toolbar by right-clicking in any toolbar area and selecting Camera.

img

The difference between camera objects and saved views is that saved views do not open in separate windows, and do not include any additional parameters, such as render mode.

Note: You can also create and manipulate camera objects, and group cameras into camera sets, via the Design Director.

Camera Object by View

Inserts the camera at the center of the view, so that the camera view is the same as the current model view. The properties of this camera are those of the default camera representing the current view, described in the Camera page of the Camera Properties The camera object itself is not visible in the current window, and a separate view window will not be created, since you are already looking at the camera view.

Camera Object Normal to View

img

Inserts the camera perpendicular to the current model view. The camera will face the same way as Camera by View, but can be placed anywhere.

Camera Object Parallel to View

img

Inserts the camera on a plane parallel to the current model view. The first point places the camera, and the second point defines its direction.

Camera By 2 Points

img

Inserts the camera by picking two points. The first point places the camera and the second point defines its direction.

Camera Object Views

img

To display the view seen by the camera object, you can create a separate view window. To create a view window, click the img icon for the relevant camera. The icon is used to show or hide the camera indicator. You can also use this dialog to edit and delete camera objects. Select: Selects the highlighted camera in the drawing. This option is useful when the drawing is large, and you are unable to find the camera in the screen.

Show All: Makes all camera objects visible.

Hide All: Hide all camera objects. To display all view windows, select Window / Cascade or Window / Tile.

img

If you change the direction of a camera in one window, the views in any attached windows will update accordingly. If you use other view controls in an attached window, the camera position will be changed.

img

Camera Object Properties

Double-click a camera object.

img

Visible - Check this box to display the camera object indicator in the view window. Attached / Detached - Check this box to create a new drawing window containing the camera view. Updates to the camera will update the view. Unchecking the box will disconnect the window from the view, so that updates to the camera will not affect the view.

Camera Sets

A camera set is a group of cameras, which can be handy if you want to set rendering, perspective, and visibility parameters for multiple cameras. Camera sets are created and manipulated in the Design Director.

The Camera

(Available in XT Pro)

Default UI Menu: View/Camera/Properties

Ribbon UI Menu:

img

In 3D space, you can view a model from any point. DoubleCAD uses the concept of a "camera" - the camera represents your eye as you view the current scene. You can easily use the standard orthogonal and isometric views, but camera tools enable you to view from any angle. The current model view contains a default camera, placed at the center of the screen, facing into the model.

Note: While "camera" means the perspective of the current view, "camera object" is something different. Camera objects are created to save and display multiple views, or views with specific parameters.

Camera Properties

Controls the position and target of the camera, as well as rendering controls. For the rendering properties, img Camera Centered: Enables the camera to turn around its own center when you use the Camera Turn tools . When not checked, the camera will turn around the

Target Point. Scroll Speed: The speed of the camera movement.

Perspective View: The visual effect of a perspective projection is similar to that of photographic systems and of the human visual system. The size of the perspective projection of an object varies inversely with the distance of that object from the center of projection.

Note: When using Perspective View, objects cannot be located or moved beyond the horizon. Select Display Horizon to display the horizon, in order to better orient yourself to the space.

View Angle: The degree of perspective foreshortening. The view gets wider as the setting gets larger.

img

Standard view and perspective view Position: The physical location of the camera. Drawing Center: Assigns the target point coordinates as the drawing center. The drawing center is always the geometric center of all the objects in the drawing.

Note: You can also access this view by selecting View / Camera / Look to Drawing Center.

Target Point: The point that the camera faces.

Drawing Center: Moves the camera to the current drawing center.

The UP Vector: Indicates which way is up for the camera. A positive Z value rotates the camera up; a negative Z value rotates the camera down.

Graphic in Front of Camera: Select the object closest to the desired view center, and the target point is attached to that object.

Note: You can also access this view by selecting View / Camera / Look to in Front Graphic.

Auto Targeting: Sets the center of rotation on the object closest to the center of the screen (the default camera position). This is relevant when moving objects using the keyboard and mouse (such as Shift + right mouse button).

Walk Through Tools

(Available in XT Pro)

Default UI Menu: View/Walk

Ribbon UI Menu:

img

Dynamic (moving) controls for moving the camera. These commands can be accessed through the Walk Through toolbar. You can display the Walk Through toolbar by right-clicking in any toolbar area and selecting Walk Through.

img

Examine

Ctrl + Right mouse button Views the model from different angles. Drag the mouse to the right to see the left side of the object. Drag downward to see the top of the object.

Slide

Ctrl + Shift + Right mouse button Moves the camera along a plane parallel to the screen. You can move the camera up, down, left or right, but not forward or backward. Drag the mouse straight up to move the viewpoint upward, drag to the left to move it left. If you drag the mouse along an angle, the viewpoint will move along the corresponding angle. It's important to remember that the camera will move in the same direction as the cursor, which means that the Model Space will appear to move in the opposite direction.

Roll

Shift + Right mouse button or Ctrl with the arrow keys. Rotates the camera around the axis that passes through the camera. This tool will rotate the viewpoint either clockwise or counterclockwise. Drag the mouse to the left to rotate the viewpoint clockwise; drag to the right to rotate counterclockwise. Vertical movement of the mouse will behave identically to the Walk control.

Walk

Simulates walking around on the current plane. This is a handy way to walk through a 3D house model, for example. Positions the camera on the current horizontal plane, also known as the viewplane. Moving the mouse forward or backward moves the viewpoint in the corresponding direction. Left or right movement turns the camera in the corresponding direction. To move the viewpoint forward, drag the cursor toward the top of the screen. To move backward, drag toward the bottom of the screen. If you drag diagonally upward toward the left or right, the viewpoint will move forward at an angle; if you drag diagonally downward to the left or right, the viewpoint will move backward at an angle.

Note: This tool will move forward or backward only when the Perspective View option is checked on the Camera page of the Camera Properties.

Turn

Rotates the camera around its center. This changes the angle of the viewpoint without relocating the camera. The viewpoint angle can be changed upward or downward. The viewpoint angle can be also be changed to the left or right. To turn the viewpoint right, drag the mouse to the right of the screen. To turn downward, drag toward the bottom of the screen. As with Slide, the viewpoint will move in the same direction as the cursor. This will have the effect of moving the view of the model on the screen in the opposite direction of the cursor motion.

Local Menu Options

While using the Walk Through controls, there are several options available on the local menu and Inspector Bar. Undo Move: Returns the view to the position in which the current mode was invoked.

img Straighten: Returns the view to a level orientation.

img Discrete Movement: Limits camera motion. When on, the camera will only move when the mouse is moving.

img Continuous Movement: Allows the camera to move as long as the left mouse button is held down. The camera movement will be in the direction the mouse was dragged. This is the default option.

img Camera properties: Opens the Camera Properties window.
