This file contains the information required to use the UF_CAM module.
This module allows the NX CAM User Function programmer to interface
with the current CAM session object and the current CAM Object Parameter
Templates object (OPT). See the documentation of the below functions for
a description of the functionality provided by these objects.

If a function takes a file name as an input parameter then this can
be a full path name or a relative path name. It can also contain
environment variables. If it is not a full path name, UF CAM will use
the directories found in the UGII_CAM_STANDARD_SEARCH_PATH to locate
the specified file.

For sample CAM application's, please refer to the following files in
the NX Open kit.

ufd_cam_create_ude.c ufd_camgeom.c
ufd_cam_sample.c ufd_cambnd_grp_data_ude.c
ufd_cam_udop.c ufd_cam_turn_autoprog.c
ufd_cambnd.c ufx_cam.c

文件描述:
This file defines those error codes which are specific to the CAM User
Function API. They do not duplicate any error codes of the NX CAM core
modules. A CAM User Function might return any NX core module error code
as well as any of the error codes defined here.

This file contains all such CAM User Function error codes regardless of
what CAM User Function module they pertain to. In this way, the programmer
has access to all CAM User Function error codes by including this one
file instead of including a separate file for each CAM User Function module.

This module combined with the faceting module interface (defined in uf_facet.h)
provides the CAM user with the capability to preprocess geometry just as in the
user interface.

Preprocessing data for CAM use in Fixed Axis Machining operations includes the
creation of a faceted model for the user defined geometry.

For preprocessing geometry for CAM purposes, the following steps are recommended
for the user:

1) Create a facet model for the geometry using the interface provided in
uf_facet.h

The user should provide the faceting parameters using the following
guidelines to ensure that the model is valid for use by CAM.

a) max_facet_edges = 3
b) number_storage_type = FACET_TYPE_DOUBLE
c) specify_surface_tolerance = true
d) surface_dist_tolerance <= 0.0381 (mm)
e) curve_dist_tolerance <= 0.0381 (mm)
f) surface_angular_tolerance <= 0.4
g) specify_curve_tolerance = true
h) curve_angular_tolerance <= 0.4
i) specify_parameters = true
j) specify_view_direction = true
k) silh_view_direction[0] = tool_axis i component
l) silh_view_direction[1] = tool_axis j component
m) silh_view_direction[2] = tool_axis k component
n) silh_chord_tolerance <= surface_dist_tolerance/2.0


2) Assigning the facet model for CAM by using the functions in this file.

To avoid duplication of interface, the user is required to use uf_facet.h
interface for creating and manipulating faceted models in NX. The faceted
models are standard NX entities in that they can have names and attributes
attached to them. Their type, etc. can be enquired in the usual way and they
are deleted in the usual way.

NX faceted models are occurrenceable and can be added to reference sets. They
are usable for visualisation and clearance analysis, but cannot be dimensioned
to, so they are of little use in drafting.

Errors returned by this module:

- UF_CAM_PREPRO_invalid_model : Input Facet Model not valid for CAM

This file contains the documentation for the pre-v16 UF_CAM module.

UF_CAM_exit_id_t is the identifier type that is passed between NX CAM and a
User Exit. This identifier is only used upon the original call to the User
Exit. After receiving this identifier the User Exit must call
UF_<module>_ask_<module> to retrieve the identifier which will be used in
further transactions with NX CAM via the User Function layer for a
particular module.

This file contains the Open C API interface to cut levels in CAM.

Cut levels can be used in both Cavity Mill and ZLevel machining to define
the levels at which the cuts take place.

The CAM cut levels routines in this file enable you to:
. Make a local copy of the cut levels for the user to look at.
. Change the range type
. Add levels defined by either a geometry tag or a z level.
. Delete levels
. Reset levels to their default settings.

There are 4 parameters that are relevant to this functionality
(defined in the file uf_param_indices.h):

UF_PARAM_CUTLEV_RANGE_TYPE
Possible values are:
UF_PARAM_clv_range_auto_generate - cut levels defined by the system
at horizontal regions of the part.
Any changes will cause the type to
be changed to 'user_defined'.
UF_PARAM_clv_range_user_defined - cut levels are defined by user
UF_PARAM_clv_range_single - Single cut range. Levels can not
be added or removed with this type.
This is the only type for which
top off functionality can be
requested.
This is a read only parameter value and can only be changed with the
UF_CUT_LEVELS_set_range_type function.

UF_PARAM_CUTLEV_RANGE_SUBDIV_TYPE
Possible values are:
UF_PARAM_clv_top_off_mode_off - Don't top off horizontal surfaces.
UF_PARAM_clv_top_off_mode_on - Do top off horizontal surfaces.
This type is only considered when the range type above is set to 'single'.

UF_PARAM_CUTLEV_TOP_OFF_MODE
Possible values are:
UF_PARAM_clv_range_subdiv_equalise - subdivide each cut range into
equal steps such that the depth
per cut of that range is not
exceeded.
UF_PARAM_clv_range_subdiv_bottoms_only
- cut at range bottoms only.
The ranges are not subdivided.
Note: the cut levels returned by the functionality supplied in this file
are the range ends. The subdivided levels are only used when the toolpath
is being generated.

UF_PARAM_CUTLEV_GLOBAL_CUT_DEPTH
The global cut depth used for subdividing the ranges. This is the value
used for both 'auto generate' and 'single' range type and is the default
value for 'user defined' range type. Note that only 'user defined' range
type can have different cut depths for different ranges.
