Since the Go!SCAN can use the object geometry for to position itself, it may happen that it loses its positioning temporarily. In order to understand why the positioning is lost, VXelements offers 3 different indicators, which can be activated in the Positioning mode.
The Show Positioning Status checkbox will activate a large icon at the top right of VXelements’ 3D Viewer. This icon will indicate to the user the main reason why the scanner has a hard time positioning itself (the explanation of these icons is available in the VXelements Help file).
The Show Slippage Directions checkbox will activate if the surface doesn’t have enough geometry to help the Go!SCAN 3D or if the geometry is ambiguous. As shown in the example below, the surface is slippery in the direction of the arrow. The solution in this case would be to add a few positioning targets to help the Go!SCAN 3D to position itself.
The Show Slippage Level on Surface checkbox will color the surface acquired by the scanner according to the risk of slippage of the object. A green surface indicates that the object is providing sufficient information for an accurate positioning. A yellow surface indicates that the positioning information provided is borderline.
Note: This tool shouldn’t be used to inspect the accuracy of the scan, it only indicates how well the scanner was positioned during the scan. To avoid misunderstanding and since the accuracy and the scanner positioning aren’t perfectly correlated, this feature isn’t available when the scanning mode is inactive.
