Description:
GET_SELECTION invokes the standard Creo Elements/Direct Modeling SELECT subaction and returns a list of the selected item(s) which satisfy the passed focus type.

Note: This interrupt action should only be used programmatically via sd-call-cmds as a way to inquire topological information from the system.

Options:
:focus_type {FOCUS_TYPE or LIST of FOCUS_TYPES ["all"]}
specifies what kinds of items are allowed to be selected.
focus_type or each element of the list of focus types must be one of the symbols shown in the table below:

Note: Non construction geometry types select real geometry only.

Note: The select focus types for Annotation objects are listed in the Annotation select documentation.

:single_selection
If you pass this parameter, the selection will be restricted on single elements only. The default is to allow multiple selection.
:curr_wp_only
when selecting 2d geometry (e.g. :focus_type = *sd-edge-2d-seltype*), only items belonging to the current workplane may be selected. The default is to allow selection on any workplane.
:curr_part_only
when selecting 3d geometry (e.g. :focus_type = s_edge_3d), only items belonging to the current part may be selected. The default is to allow selection in any part.
:allow_face_part
when selecting a part, allow a face part to be selected. The default is to not allow face parts.
:allow_wire_part
when selecting a part, allow a wire part to be selected. The default is to not allow wire parts.
:allow_graphics_only
when selecting a part or assembly, allow a lightweight object be selected. The default is to not allow lightweight objects.
Possible values are:
  nil                   ;default
  (list :part)
  (list :assembly)
  (list :part :assembly)
:with_stock_container
when selecting an assembly, allow a stock container to be selected. The default is to not allow stock container.
:disable_automatic_reload
when selecting a lightweight part or 3D element allow to automatically reload the item or not. The default is to allow automatic reload of lightweight items.
:no_highlight
the selected entities and objects will not be highlighted. The default is to highlight the selected entities and objects.
:check_function {LISP function}
specifies a Lisp function to use to verify whether or not selected items are valid. This function must take as input a sel_item structure. It must return :ok if the item is acceptable, or, if the item is not acceptable, then it must return either :filter to silently remove the item from the selection list or :error to halt the selection and return no selection values.
:select {any valid SELECT parameters}
after all other options have been specified, this option invokes the select subaction. At this point you can pass any number of valid SELECT options.

Return Value:
item {SEL_ITEM}
if single_selection was set and an object was successfully selected.
items {LIST of SEL_ITEMs}
if the parameter single_selection was not given and one or more objects were successfully selected.
nil - if no objects were selected

Examples:

Select all top-level parts in the system, including wire and face parts:

   (sd-call-cmds (get_selection :focus_type *sd-part-seltype*
                                :allow_wire_part

                                :select
                                :all_at_top))

                                :in_assembly assembly-sel-item))

                                :select 
                                :current_part
                                :all_3d))
Select all circular edges of a specific part:
   (sd-call-cmds (get_selection :focus_type *sd-circle-3d-seltype*
                                :select

                                :all_3d))
Select all planar faces of a specific part:
   (sd-call-cmds (get_selection :focus_type *sd-plane-seltype*
                                :select
                                :selected_part part-sel-item
                                :all_3d))
Select a list of all faces of a part that have a transparency setting greater than 0.5:
  (defun check-transparent-face (face)
    (let ((ft (sd-inq-face-transparency face)))
      (if (and ft (>= ft 0.5))
        :ok
        :filter)))

  (sd-call-cmds (get_selection :focus_type *sd-face-seltype*
                               :check_function #'check-transparent-face
                               :select

SD-GET-FACES-ALONG-RAY  [function]

(sd-get-faces-along-ray part ray-point ray-direction
                        :include-details  include-details-flag
                        :in-dir-only      in-dir-only-flag)
Description:
Returns all faces of the specified part which were hit by the specified ray. The return list is ordered by distance from the ray point.

Parameters:
part {SEL_ITEM} - the part through which the ray is fired
ray-point {gpnt3d} - a global 3D point on the ray
ray-direction {gpnt3d} - the direction of the ray
:include-details {BOOLEAN [t]}
If this parameter is given, the result list contains for each hit face the hit point on the face (in global coordinates) and the distance of the hit point to the passed ray point.
:in-dir-only {BOOLEAN [t]}
If given, only faces which were hit in the given ray direction are returned. If this parameter is nil, all faces along the ray in both directions from the ray point are collected.

Return Value:
list of faces (and details) {LIST}
In case :include-details was set to nil, a plain list of hit face sel_items is returned.
If :include-details was set to t, each entry of the result list consists of the following items:
  1. face sel_item
  2. coordinate of the hit point on the hit face in global coordinates
  3. distance of the hit point to the passed ray point
nil - no faces hit or other failure
