PolyWorks script development learning notes (4) - data import and alignment using file import

Polyworks Script development learning notes ( Four )- utilize FILE IMPORT Import and align data

Import reference and data

1. FILE IMPORT_REFERENCE Import referenced CAD Documents such as igs Format
   
   The parameters in brackets are ( Import file path ,CAD layer -, Original file path )
   FILE IMPORT_REFERENCE NURBS IGES ( “D:\CAD\11.igs”, , ) Import CAD file D:\CAD\11.igs
   FILE IMPORT_REFERENCE NURBS IGES ( “D:\CAD\11.igs”,“aa” , ) Import CAD file D:\CAD\11.igs Of "aa" layer
   FILE IMPORT_REFERENCE NURBS IGES ( {“D:\CAD\11.igs”,“D:\CAD\22.igs”}, , )
   Import two... As a string array CAD file D:\CAD\11.igs and D:\CAD\22.igs
   FILE IMPORT_REFERENCE NURBS IGES ( “D:\CAD\11.igs”, “D:\CAD\22.igs”)
   Import "D:\CAD\11.igs" replace "D:\CAD\22.igs"

Of course , It is also possible to import triangulated models as reference data , as follows :
FILE IMPORT_REFERENCE POLYGONAL_MODEL ( “D:\PtCloud\111.stl”, “stl”, )

2. FILE IMPORT_DATA Import the compared data
   There are many formats for importing triangulated data, as follows , The most commonly used is stl Format
   FILE IMPORT_DATA POLYGONAL_MODEL( “D:\PtCloud\111.stl”, “stl”, ) Import “D:\PtCloud\111.stl” As comparison data
   FILE IMPORT_DATA POLYGONAL_MODEL( {“D:\PtCloud\111.stl”,“D:\PtCloud\222.stl”}, “stl”, )
   Import “D:\PtCloud\111.stl” “D:\PtCloud\222.stl" Multiple triangulated data are used as comparison data
   FILE IMPORT_DATA POLYGONAL_MODEL( “D:\PtCloud\111.stl”, “stl”,“D:\PtCloud\222.stl” )
   Import “D:\PtCloud\111.stl” replace "D:\PtCloud\222.stl”

Set best fit alignment

Best fit alignment , Is to compare the data DATA And reference data REFERENCE A simple method of alignment using best fit
Using scripts requires setting alignment parameters first , Then the alignment method is realized .
For example, using best fit will 111.stl And 11.igs alignment

Set specified （ step 2） Reference objects for 11.igs( step 3)
Set specified （ step 4） Data objects for 111.stl( step 5)
Use pre alignment ( step 1) Align the best fit of the above data object to the reference object , Name it " Best fit to reference 5"( step 6)

ALIGN BEST_FIT DATA_TO_REFERENCE OPTIONS CREATE REFERENCE_OBJECTS ( “Specific” ) step 2
ALIGN BEST_FIT DATA_TO_REFERENCE OPTIONS CREATE REFERENCE_OBJECTS SPECIFIC ( “11.igs” ) step 3
ALIGN BEST_FIT DATA_TO_REFERENCE OPTIONS CREATE DATA_OBJECTS ( “Specific” ) step 4
ALIGN BEST_FIT DATA_TO_REFERENCE OPTIONS CREATE DATA_OBJECTS SPECIFIC ( “111.stl” ) step 5
ALIGN BEST_FIT DATA_TO_REFERENCE CREATE FIT_TO_REFERENCE_OBJECT_SURFACES USING_PRE_ALIGNMENT AUTOMATIC ( “ Best fit to reference 5” ) step 1+ step 6
