The Annotation Scale setting allows you to modify the size of the annotation open within the 3D viewer. This may be used if the initial annotation size is not ideal for the zoom level you prefer for the model.

The default is 10, but you can enter any number greater than 1 to adjust the scaling factor relative to the original size of the annotation. Click Apply to see the result of the scale, then Close to exit the dialog.

This scale is not applied to annotation configured using a manual scaling. If your charts do not seem to be changing scale, contact your CM4D administrator who designed the annotation used in Peruse.

The Camera Menu provides preset camera options to quickly move the model to a preset orientation.

Name	Icon	Description
Iso View		Isometric view orients the model so the angles between the XYZ axes are equal.
Orthographic Projection		This projection displays the view in a fixed depth. The model does not scale X and Y coordinates depending on the Z coordinate so the direction of the projection is perpendicular to the camera target plane.
Perspective Projection		This projection displays the view with depth. The model scales the X and Y coordinates depending on the Z coordinate (depth) so objects that are further away appear smaller on the screen.
Left View		Orients the model to view the left side (ZX).
Right View		Orients the model to view the right side (XZ).
Bottom View		Orients the model to view the bottom (YX).
Front View		Orients the model to view the front (ZY).
Back View		Orients the model to view the back (YZ).
Top View		Orients the model to view the top (XY).

Close Annotation closes all open annotation attached to the Feature markers in the 3D View. This button is disabled until at least one annotation is open.

The Cutting Plane tools allow you to add or remove cutting planes on the 3D model. To open the fly-out menu, click the fifth icon from the top of the viewer toolbar.

Name	Icon	Description
Toggle X Plane		Toggles the cutting plane along the X axis on/off.
Invert X Plane		Enabled when the X plane is active. Flips the cutting plane to cut the geometry in the opposite direction along the X axis.
Toggle Y Plane		Toggles the cutting plane along the Y axis on/off.
Invert Y Plane		Enabled when the Y plane is active. Flips the cutting plane to cut the geometry in the opposite direction along the Y axis.
Toggle Z Plane		Toggles the cutting plane along the Z axis on/off.
Invert Z Plane		Enabled when the Z plane is active. Flips the cutting plane to cut the geometry in the opposite direction along the Z axis.
Show/Hide Planes		Enabled when at least one cutting plane is active. Toggles the visibility of the cutting plane bounding box. By default, the cutting plane reference box is visible. While the plane is hidden, it cannot be moved.
Toggle Quadrants		Enabled when two or more planes are active. Toggles the cutting planes from a single cutting section to separate cutting sections. OFF - All enabled planes are combined to act as a single cutting plane; cuts all geometry intersected by any plane. ON - Each enabled plane acts an individual plane; cuts only geometry intersected by all planes.
Reset		Enabled when at least one cutting plane is active. Sets all cutting plane locations to default and turns off all cutting planes.

The Display Mode toolbar has options for changing the rendering of the 3D Model to one of four predefined modes. A flyout menu contains the four options; the icon for the current mode is shown in the toolbar.

Name	Icon	Description
Shaded with Lines		[Default Mode] Sets the rendering mode to Phong Shading with Lines. This mode displays the model geometry as shaded and opaque, with the addition of visible, unobscured lines. Colors are obtained from the CAD file. This is essentially a combination of the Shaded and Hidden Lines modes. This mode may display some parts better than just Shaded.
Shaded		Sets the rendering mode to Phong Shading. Colors are obtained from the CAD file. This mode displays the model geometry as shaded and opaque.
Hidden Lines		Sets the rendering mode to Fast Hidden Line. This mode displays only visible, unobscured lines. Faces of visible geometry are used to obscure the lines in the model. All color defined in the CAD file is turned white. This mode is a simple view that may provide a better result for hardcopy or screenshots.
X-Ray		Sets the rendering mode to X-Ray. This mode displays the model geometry as semi-transparent, but not the feature markers. This mode allows you to see through a complex scene to view or select the Feature markers.

The Feature Marker Settings include options for Feature marker modes and resolutions. These options may effect the load-time performance for Feature markers.
