) 

Parameters

DoubleInfoIn

Array of 7 doubles: 3 for the start point of the ray, 3 for the direction of the ray, and 1 for the radius

TypeWanted

Type of objects to select as defined in swSelectType_e

Return Value

True if a selection is made, false if not

This method:

• Defines a cylindrical region of infinite length that begins at pointIn, runs parallel to VectorIn, and has a radius of RadiusIn. If you specified edge or vertex entities, then the first edge or vertex found within the selection cylinder is selected.

• Only selects entity objects, which include faces, edges, vertices, and so on. You cannot select ISketch objects using this method.

• Does not support the selection of silhouette edges.

Only a single entity is selected within the distance radius regardless of multiple entities existing within that radius. For selecting face entities, RadiusIn is ignored and a cylinder of infinitely small radius is used.

Use model space view to determine the selection vector in a drawing.
