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

Append

True to append the selections to the current selection list, false to not

Return Value

True if an object is selected, 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 edges or vertices, then any edge or vertex found within the selection cylinder is selected.

• Selects only entity objects, which include faces, edges, and vertices. You cannot use this function to select ISketch objects.
  
  When selecting face entities, RadiusIn is ignored and a cylinder of infinitely small radius is used.
