Use the Viewsdialog to control the default view details.
Perspective View Angle – This affects how perspective views appear. A value of zero degrees puts the vanishing point at an infinite distance, creating an orthographic view. Wider angles create a feeling of depth and distance, with really wide angles distorting the image to the point where there is no visible depth. The default angle is 40 degrees.
Depth cueing – When switched on, objects and parts of objects are drawn progressively less brightly as they fall further from you. This gives a feeling of depth as if receding into the mists of distance.
Wireframe antialiasing – Wireframe antialiasing smoothes out the raster effect caused by the display indicating curves and angled lines as a string of short straight lines. The side effect is that smoothed lines are drawn thicker, so many people prefer to work with this option switched off.
Instrumentation on top when shaded – When you select an object (for example a solid block) in shaded mode, its edit handles are displayed on top of the shading.
Open model in – Use the drop-down list select the default view to be used when opening a model.
Default Layout – This defines the default view layout for new windows. Click the Default Layout button to display the View Edit dialog. Use this dialog to define the default view layout.
View rotation – When you drag the middle mouse button the view rotates in 3D as if within a ball. The two menus in this option control how the rotation behaves and the tracker ball graphic colour.
Rotate around has three options:
Selection causes the view to rotate around the selected point on the selection. If nothing is selected, it reverts to the centre of the view.
Active Workplane causes the view to rotate around the currently active workplane origin. If no workplane is active, it reverts to the centre of the view.
View centre causes the view to rotate around the centre of the view.
Tracker ball colour has three options:
Dull draws the tracker ball lines in a colour which does not contrast heavily with the active window background colour.
Bright draws the tracker ball lines in a colour which does contrast heavily with the active window background colour.
Invisible hides the tracker ball lines during view rotations.
View Spinning – When you drag the middle mouse on a view, the view rotates. You can turn on View Spinning so that the view continues to rotate after you release the middle mouse. The view is rotated in the direction that you moved the mouse.
Rotation Tracker – If ON, axes are drawn in the bottom left corner of the view to show the direction of the X, Y and Z axes.
If an axis points away from you, it is drawn dim.
The axes on the rotation tracker, which represent the active plane, are drawn in a different colour to the axis perpendicular to the plane. The colours are set in the scm file. Minimum frames per second – This defines the minimum acceptable frames per second when dynamically rotating, zooming and panning. If the view cannot achieve the requested minimum frames per second, objects are omitted while dynamically changing the view. A value of 0 means there is no minimum.
Time limit – The time it should take to animate between view orientations
