Solid

Source file: filter-by-solid.htm

Use Filter by solid to filter scan data specified by a 3D solid shape and retain points inside or outside the shape.

This is an extension of the Filter by polygon function. Whereas the Filter by polygon function can define a region based on a polygon and extruded into 3D space, the Filter by solid function allows full control in defining the 3D volume of interest. For example, this allows a more detailed capability in defining regions around caverns in underground mines.  

1. Create or select a 3D solid shape to use.

2. On the Position and Filter ribbon tab, go to the Filter group. From the Filters drop-down list select Solid.

   

3. Drag the solid shape into the Solid field. The solid shape boundary is displayed in grey.

   

4. Choose to keep points Inside or Outside the solid shape.

5. Select the required Filter combination.

6. Select the scan data to filter.

7. Click OK or Apply.

   Result of keeping the points outside of the solid.

Tip:  You can redisplay the points hidden by the filter using the Show All option. See Show All.
