•Delete. The current camera view will be removed from the list.

•Save. The current specified data will be saved under the view name.

ØPosition. XYZ coordinates from the camera position. This values will be updated when you move the camera.

ØView direction. XYZ coordinates from the camera view direction vector. This values will be updated when you rotate the camera.

ØProjection type. In perspective mode objects farther from the camera will appear smaller. In orthographic mode you can view object in true isometric or plan view.

ØProjection plane distances. These planes are perpendicular to the camera view direction. Everything between the front and back plane and inside the camera frustrum will be visible. The distances must be positive and are measured from the camera position to the plane in the view direction.

ØField of view. Is the open observable area from the camera position. Enter value in decimal degrees. Applies only for perspective mode projection.

ØView width. The view width can only be specified in orthographic projection mode because the bounding planes are parallel.

ØCamera stepping. you can move the camera in the current view direction at the specified stepping distance pressing the backward or forward button.

ØApply settings. Press this button to update the current view using the data specified.

Tips:

•If you set the camera to orthographic projection mode and use the default view width, when you insert an image of the current view in the drawing it will have real world dimensions units.

•If you define new camera views, you must select to save when closing the Mesh Viewer and save the drawing to permanently store the view data.
