+====== Surface3D Parameters ======
+Surface3D has a set of application-wide parameters that allows users to control how they interact with surface models.
+===== Auto Hole Threshold =====
+Specifies the size (in number of voxels) of the largest volume that will be filled by the auto hole-filling command. This command works by finding each unlabelled voxel next to a labelled voxel and using a flood-fill algorithm to find all unlabelled voxels that are connected to it. If the size of this region is less than //Auto Hole Threshold,// then the region is labelled with the current label.
+The default value is 2000.
+===== Decimation Factor =====
+Specifies the approximate percentage of polygons that will be removed from the object surface during decimation (//Model -> Decimate Surface Model//).
+The default value is 0.2, meaning that approximately 20% of the polygons will be removed each time the decimate command is performed.
+===== Feature Edge Smoothing =====
+Turns on (true) and off (false) smoothing of sharp interior edges on the surface model during smoothing (//Model -> Smooth Surface Model//).
+The default value is false.
+===== Paintbrush Radius =====
+The radius (in voxels) of the circular paintbrush that is used for label painting and label erasing.
+The default value is 5.
+===== Relaxation Factor =====
+Specifies the relaxation factor for the Laplacian smoothing performed by the smoothing command (//Model -> Smooth Surface Model//).
+The default value is 0.2.
+===== Smoothing Iterations =====
+The number of iterations of Laplacian smoothing performed by the smoothing command (//Model -> Smooth Surface Model//).
+The default value is 300.
+===== Text Radius =====
+Scale factor for POI and landmark text labels.
+The default value is 0.75.
+===== Undo Limit =====
+The maximum number of label editing actions that can be undone.
+The default value is 10.
