Scheme Extensions

 

Technical Article
Scheme is a public domain programming language, based on the LISP language, that uses an interpreter to run commands. ACIS provides extensions (written in C++) to the native Scheme language that can be used by an application to interact with ACIS through its Scheme Interpreter. The C++ source files for ACIS Scheme extensions are provided with the product. Spatial's Scheme based demonstration application, Scheme ACIS Interface Driver Extension (Scheme AIDE), also uses these Scheme extensions and the Scheme Interpreter.

Action
Deprecated: This scheme extension has been deprecated because it calls a deprecated API.

Filename
scm/scmext/heal/scm_heal.cpp

APIs
api_hh_geombuild_check

Syntax
(hh:analyze-geom body [acis-opts])

Arg Types
body body
acis-opts acis-options

Returns
real

Description
This extension performs the analyze stage of the geometry building phase. The geometry building phase performs all the geometry related healing operations, including fixing of edge geometries by intersections, snapping surfaces for fixing tangencies, and refitting spline surfaces.

A check is run on the body and the inaccurate geometries are marked with attributes. An invalid edge is one in which the edge curve does not lie on the underlying surfaces to ACIS tolerance. A vertex is marked bad if it does not lie on the edges or faces which are incident on it. A bad coedge is one whose pcurve and edge curve do not match.

Arguments
The optional argument acis-opts helps enable journaling and versioning options.

Limitations
The entity must be a body. Individual sheet bodies or faces can be combined into a single body using the hh:combine extension.

hh:analyze-simplify

Action
Deprecated: This scheme extension has been deprecated because it calls a deprecated API.

Filename
scm/scmext/heal/scm_heal.cpp

APIs
api_hh_simplify_analyze

Syntax
(hh:analyze-simplify body [simp-opts] [acis-opts])

Arg Types
body body
simp-opts Simp_Options
acis-opts acis-options

Returns
unspecified

Description
This extension analyzes the body and intelligently sets values of required options and tolerances for geometry simplification. Geometry simplification attempts to simplify NURBS surfaces into analytic forms (planes, cylinders, cones, tori, and spheres). If the body is fully analytic, this extension sets a flag in the simplification aggregate attribute indicating that no geometry simplification is needed.

Arguments
body specifies the input body.

simp-opts specifies the optional argument, Simp_Options object that has been added since ACIS version R11. It sets the parameters which govern the functionality of hh:analyze-simplify. The constructor of Simp_Options sets the values of all the parameters as -1. The parameters that can be set are:

simplify_pos_tol has a default value of -1, that is the scheme command computes a default value based on its own heuristics.

max_radius has a default value of -1, that is, a maximum radius of 10,000.

do_curve_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1, that is, curve simplication behavior is set to ON.

do_surface_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1, that is, surface simplication behavior is set to ON.

Note:
(1) Selecting -1 as the value for any of these parameters enables the respective algorithm to employ its default behavior.
(2) In ACIS R11 and later, both curve simplification and surface simplification are done by default. In R10 and earlier, only surface simplification was done by default and there was no curve simplification. To make hh:analyze-simplify behave as in R10 or an earlier release, the caller of the API requires creating a simp_options options object. Do this by setting do_curve_simplification to "0" and passing this object into the scheme command.

acis-opts is an optional argument enabling journaling and versioning options.

Limitations
The entity must be a body. Individual sheet bodies or faces can be combined into a single body using the hh:combine extension.

hh:autoheal

Action
Heals anomalies in the input body.

Filename
scm/scmext/heal/scm_ah.cpp

APIs
api_hh_auto_heal

Syntax
(hh:autoheal body [filename] [acis-opts])

Arg Types
body body
filename string
acis-opts acis-options

Returns
unspecified

Description
This extension takes a body and returns a body which may be partially healed. The body may consist of individual faces built with the hh:combine extension.

The extension scans the input entity looking for inconsistencies in the topology. It removes some inconsistencies, such as edges without geometry. It also trims the surface geometries wherever possible.

The steps taken are:

  1. Preprocess the body, checking for inconsistencies such as edges without geometry. Trim surface geometries whenever possible.
  2. Test and simplify any spline surfaces which meet the testing criteria. For example, if the spline surface can be represented by an analytic surface within the tolerance, replace the spline surface with the appropriate analytic surface (plane, cylinder, etc.).
  3. If the input consists of faces, determine a stitching tolerance, and attempt to stitch the faces into either a complete solid or a single sheet body.
  4. Analyze and heal the stitched geometry:

Build constraints by analyzing all tangency conditions.

Solve analytic surface constraints by modifying analytic surfaces to satisfy the tangent constraints.

Re-intersect transverse edges.

Solve tangent spline constraints by modifying the associated spline surfaces.

If the optional filename string is supplied, a summary will be written to the file. A suffix of .log is appended to the filename.

Arguments
The optional argument acis-opts helps enable journaling and versioning options.

Syntax
(hh:get-simplify-tol body)

Arg Types
body body

Returns
real

Description
The geometry simplification tolerance is the tolerance at which spline surfaces get simplified to analytic surfaces. If the tolerance is tight (as default is), only spline surfaces that are exact analytic surfaces get simplified. If the tolerance is loosened, then approximate analytic fits to splines are obtained. In such cases, the gaps between surfaces may increase and healing in subsequent operations may be more difficult. The need for increasing tolerances typically arises when analytic surfaces are output as NUBS surfaces rather than NURBS surfaces. The default tolerance is 0.0001 (length units), which obtains a very good approximation of analytic surfaces to spline surfaces in most models.

Arguments
Input argument is the body whose geometry simplification tolerance is to be obtained for healing.

(hh:set-isospline-tol tolerance)

Arg Types

Description
The isospline solver attempts to heal all edges shared by tangential isoparametric surfaces (for example, the intersection curve is an isoparametric curve of both splines in the intersection). It calculates isoparametric junctions of spline geometries intersecting tangentially.

Syntax
(hh:set-simplify-tol tolerance)

Arg Types
tolerance real

Returns
unspecified

Description
The geometry simplification tolerance is the tolerance at which spline surfaces get simplified to analytic surfaces. If the tolerance is tight (as default is), only spline surfaces that are exact analytic surfaces get simplified. If the tolerance is loosened, then approximate analytic fits to splines are obtained. In such cases, the gaps between surfaces may increase and healing in subsequent operations may be more difficult. The need for increasing tolerances typically arises when analytic surfaces are output as NUBS surfaces rather than NURBS surfaces. The default tolerance is 0.0001 (length units), which obtains a very good approximation of analytic surfaces to spline surfaces in most models.

hh:simp-options

Action
Returns an object of Simp_Options.

Filename
scm/scmext/heal/scm_heal.cpp

APIs
None

Syntax
(hh:simp-options "name-of-option" {value(s)} {options})

Arg Types
"name-of-option" string
value integer
options Simp_Options

Returns
Simp_Options

Description
This extension returns a Simp_Options object for use in hh:analyze-simplify and hh:simplify. This allows you to set the simplification tolerance, maximum permissible circle radius, and the option of switching curve and face simplification ON/OFF.

Arguments
"name-of-option" specifies the name of the option.

value specifies the value of option.

options specifies the different Simp_Options.
Note: Simp_Options object sets the parameters which govern the functionality of hh:simplify and hh:simplify-analyze. The parameters are:

simplify_pos_tol has a default value of -1.

max_radius has a default value of -1.

do_curve_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1.

do_surface_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1.

The default value of -1 for these parameters allows the respective algorithm to undergo its default behavior.

Errors
simplify_pos_tol option requires a real number as argument.

max_radius option requires a real number as argument.

do_curve_simplificaition option requires integer argument.

do_surface_simplification option requires integer argument.

Incorrect simplify option.
;1. Load the body
(part:load "xxx.sat" )
(define body (hh:combine (part:entities)))

;2. Make the simplification options object "Simp_Options"
(define so (hh:simp-options "do_curve_simplification" 1 "simplify_pos_tol" 0.001))

; To check the values of parameters of simp-options, type the option's name at the prompt
so

;3. For updating the parameters of an existing Simp_Options object, the same scheme command
; (hh:simp-options ) can be used by passing the options object as the last argument.
; (For example: hh:simp-options "do_surface_simplification" 1 so)

;4. Call simplification
(hh:simplify body so)

hh:simplify

Action
Simplifies spline geometry of the input body where possible.

Filename
scm/scmext/heal/scm_heal.cpp

APIs
api_hh_simplify_auto

Syntax
(hh:simplify body [simp-options] [acis-opts])

Arg Types
body body
simp-opts Simp_Options
acis-opts acis-options

Returns
body

Description
This extension replaces the spline surfaces with the equivalent analytic representation where possible. This extension must follow the analysis extension.

Arguments
body specifies the input body whose spline geometry is to be simplified.

simp-opts specifies the optional argument, Simp_Options object that has been added since ACIS version R11. It sets the parameters which govern the functionality of hh:simplify. The constructor of Simp_Options sets the values of all the parameters as -1. The parameters that can be set are:

simplify_pos_tol has a default value of -1, that is the scheme command computes a default value based on its own heuristics.

max_radius has a default value of -1, that is, a maximum radius of 10,000.

do_curve_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1, that is, curve simplication behavior is set to ON.

do_surface_simplification has values of -1, 0 (OFF), and 1 (ON). The default value is -1, that is, surface simplication behavior is set to ON.

Note:
(1) Selecting -1 as the value for any of these parameters enables the respective algorithm to employ its default behavior.
(2) In ACIS R11 and later, both curve simplification and surface simplification are done by default. In R10 and earlier, only surface simplification was done by default and there was no curve simplification. To make hh:simplify behave as in R10 or an earlier release, the caller of the extension requires creating a simp_options options object. Do this by setting do_curve_simplification to "0" and passing this object into the scheme command.

APIs
api_hh_stitch_auto

Syntax
(hh:stitch body [acis-opts])

Arg Types
body body
acis-opts acis-options

Returns
body

Description
This extension attempts to stitch the input set of faces into a solid or single sheet body.

A small stitch tolerance is selected and all faces that can be stitched together at that tolerance are processed. Then the tolerance is increased and the remaining faces are processed and stitched if possible. This process is continued until all faces are stitched together or a maximum stitch tolerance is exceeded.

Arguments
Argument body inputs the set of faces or individual sheet bodies that need to be stitched. Individual sheet bodies or faces can be combined into a single body using the hh:combine extension.
 
incr-only sets incremental stitching.
 
The optional argument acis-opts helps enable journaling and versioning options.

Limitations
The entity must be a body. Individual sheet bodies or faces can be combined into a single body using the hh:combine extension.
