Namespace: Autodesk.Revit.DB.PointClouds

PointCloudFilter

Class

Description:
A class used to describe the criteria an application desires when obtaining members of a point cloud.

Remarks:
Client applications which wish to obtain points from a point cloud will have to create a PointCloudFilter to define the volume of interest (see PointCloudFilterFactory). Engine implementations will need to use the methods contained within the point cloud to determine which points to return to Revit.

Examples

// Filter will match 1/8 of the overall point cloud
// Use the bounding box (filter coordinates are in the coordinates of the model)
BoundingBoxXYZ boundingBox = pointCloudInstance.get_BoundingBox(null);
List<Plane> planes = new List<Plane>();
XYZ midpoint = (boundingBox.Min + boundingBox.Max) / 2.0;

// X boundaries
planes.Add(Plane.CreateByNormalAndOrigin(XYZ.BasisX, boundingBox.Min));
planes.Add(Plane.CreateByNormalAndOrigin(-XYZ.BasisX, midpoint));

// Y boundaries
planes.Add(Plane.CreateByNormalAndOrigin(XYZ.BasisY, boundingBox.Min));
planes.Add(Plane.CreateByNormalAndOrigin(-XYZ.BasisY, midpoint));

// Z boundaries
planes.Add(Plane.CreateByNormalAndOrigin(XYZ.BasisZ, boundingBox.Min));
planes.Add(Plane.CreateByNormalAndOrigin(-XYZ.BasisZ, midpoint));

// Create filter
PointCloudFilter filter = PointCloudFilterFactory.CreateMultiPlaneFilter(planes);
pointCloudInstance.FilterAction = SelectionFilterAction.Highlight;

return filter;
