Zoom

Zooms the current view in and out.

Steps:

• Drag a rectangle in a viewport.

The view defined by the rectangle fills the viewport.

Options

Default (window)

Drag a window to zoom.

All

Zooms all viewports.

• Click an option.

Options

Extents

Selected

1to1

Dynamic

Zooms the view dynamically.

• Hold down the left mouse button and drag the mouse up and down to zoom in and out.

Extents

Zooms the view to show all objects.

Factor

Zooms the view in or out the specified amount. Values greater than 1 zoom in; values between 0 and 1 zoom out.

In

Zooms the view in.

Out

Zooms the view out.

Selected

Zooms the view to show all selected objects.

Target

Zooms the view by specifying a target and window.

• Pick a location for the view center.

A rectangular window forms to define the zoom with the target as the view center.

When you rotate a view after Zoom Target, the scene will rotate about the target. This is particularly useful in perspective views.

1To1

Zooms the active viewport so that the view is full scale.

The command must be calibrated for this command to work properly.

In perspective views, only objects on the target plane will be displayed full scale; in parallel views objects on any plane perpendicular to the camera axis are displayed full scale.

The model must have units set.

DollyZoom

In a Perspective viewport, moves the camera location and changes the lens length at the same time, keeping the objects at the target plane about the same size.

Steps:

• Click the left mouse button in the viewport and drag.

Note: When the cursor moves near the viewport corners, a snapping mode is enabled. The Lens length of the view camera snaps in 5mm increments.

SetZoomExtentsBorder

Sets the amount of blank space between objects and the viewport edges when the Zoom command, Extents option is used.

After the object extents bounding box is calculated, this box is scaled based on the scale factors set by this command, increasing the space between objects and the viewport borders.

Steps:

• Specify a scale for the view border.

Options

Scale factor

Greater than 1

Increases the space between objects and the viewport borders.

Less than 1

Decreases the space between objects and the viewport borders.

ParallelView

Sets the border size for parallel views.

PerspectiveView

Sets the border size for perspective views.

ZoomLens

Adjusts the lens length of the viewport camera in a perspective view.

ZoomNaked

Finds and marks naked edges.

Steps:

• Select objects.

The active view zooms to display the first naked edge.

Options

All

Zooms to all naked edges.

Current

Zooms to the current naked edge. This useful if you zoom out with the mouse and want to zoom back in.

Next

Zooms to the next naked edge. If the selected objects have only one naked edge, this option is not displayed.

Previous

Zooms to the previous naked edge. If the selected objects have only one naked edge, this option is not displayed.

Mark

Marks the current naked edge by adding point objects at each end. If the All option was previously selected, all naked edges are marked.

Zoom1to1Calibrate

Calibrates the screen for the Zoom command, 1To1 option.

Steps:

1. Measure the bar on the screen with a ruler.

2. Type the length and unit system in the calibration box.

Camera

Shows, hides, and toggles the visibility of the viewport camera.

Keyboard Shortcut: F6

Steps:

The view camera is a representation of the view displayed in a one viewport and is visible in all the other viewports.

Use the view camera's control points to drag the camera and target points and change the lens length of the perspective viewport.

The view camera that displays is a representation of the camera and target for the viewport that is active when the Camera command is started, or the viewport where you switched on Show Camera in the right-click viewport title menu.

The camera is associated only with the viewport for which it is shown. However, it is only seen in the other viewports.

The pyramid shape indicates the camera field of view. The control point at the tip of the pyramid is the camera viewpoint. The point at the opposite end of the straight line that runs through the axis of the pyramid is the target point. The point on the middle of one side of the pyramid base is the roll control. The point on the corner adjusts the field of view/lens angle. The dotted rectangles are near and far clipping planes. You cannot see anything farther away than the far clipping plane, nor nearer than the near (to the camera point) clipping plane.

The purpose of the view camera is to show a graphical representation of the camera's location, angle, and field of view. For example:

• You may want to place a light above and to the left of the camera of the perspective view. You can turn on that camera and see it while you place the light using the other views.

• You may want a light to have a strong specular reflection in the top surface of the object to render: if you can see the camera, you can set the light to be opposite to, and at the same angle as, the camera.

• You can set the camera's viewpoint to a specific part of a model with object snaps by dragging the camera point to the endpoint of a line, surface edge, etc.

• The Zoom command Target option lets you set the camera target and then zoom to a window around it. You don't need to see the camera to do this, but the camera helps to illustrate the target's usefulness.

Options

Hide

Hides the view camera.

• Click Hide or type H.

Toggle

Toggles the visibility of the view camera.

• Click Toggle or type T.

OrientCameraToSrf

Moves a viewport's camera and target locations to align along a selected surface normal.

Steps:

1. Select a surface.

2. Pick a point on the surface to point the viewport camera toward.

Options

Flip

SetConstructionPlane

If Yes, the viewport's construction plane is set to the modified view.

MoveTargetToObjects

Moves a viewport target's position to the center of the bounding box of selected objects.

Steps:

• Select objects.

RotateCamera

Rotates the view around the camera.

Steps:

• Click the left mouse button and drag in a perspective viewport to rotate the viewport camera.

- or -

Click an option.

Notes

• This command uses the settings from the Rotate section of the Options dialog box View page to control what axis the viewport camera is rotated about and which way things move when you press and arrow key, etc.

Options

Down

Rotate the target down.

Left

Rotate the target left.

Right

Rotate the target right.

Up

Rotate the target up.

RotateView

Rotates the view camera around the target.

Keyboard Shortcut: Ctrl + Shift + drag with the right mouse button.

Note: Views that are not looking perpendicular to the construction plane rotate with the right mouse button.

Options

Down

Rotate the view camera down.

Left

Rotate the view camera left.

Right

Rotate the view camera right.

Up

Rotate the view camera up.

TiltView

Rotates the view around the axis formed by the line between the view camera and target.

Steps:

• Click and drag in a viewport to tilt the view.

Note: When the cursor moves near the viewport corners, a snapping mode is enabled. The view rotation snaps in five-degree increments. The keyboard shortcut, Shift + Alt + Right mouse button displays an "s" to indicate the snap mode is on.

Options

Left

Rotates the view anti-clockwise.

Right
