View in Stereo

Dealing with the synchronization of the Orbit GIS X map canvas and the stereo view can be done in the 'View in Stereo' sidebar.

• No sync Viewers: the movements (panning) in the Orbit GIS Interactive window are independent of the panning in the Softcopy window.
• Sync 2D from Stereo: moving the floating mark causes a parallel move in the Orbit GIS window. Only when the floating mark XY coordinate comes close to a border of the Orbit GIS X window, the Orbit GIS X window will be redrawn with coordinate value of the floating mark in the center.
• Sync Stereo from 2D: panning the Orbit GIS X datasets will cause the floating mark to follow the movements made in Orbit GIS X.
• Toggle 'Sync Scale': when this toggle is set, the Orbit GIS viewer will automatically be zoomed in, each time the zoom is used in the Softcopy window.
  
  

Dealing with the snapfunction of Orbit GIS X (see preferences: editing) can be done by the 'Snap to XY' and 'Snap to XYZ' function. The proximity in which vertices have to snap in directions X, Y and Z is indicated in an amount of pixels near the snappable point and can be changed in the snap preferences (see Preferences of Editing). Those preferences are synchronized with the ones indicated in the beside 'View in Stereo' sidebar. This gives:

for a 3D dataset:

• Snap to XY : the z-value for snapping is disabled; the z-value will be taken from the floating mark height.
• Snap to XYZ: the z-value for snapping is enabled; z-value will be taken from the snapped point.

for a 2D dataset:

• Snap to XY : z-value will be zero.
• Snap to XYZ: z-value will be zero.

Take into account that the OrbitGIS Mapcanvas zoom will be used to deal with the snap proximity. Synchronizing the views is recommended.
