PROE強大的參數化建模能力在各種領域應用廣泛。本文討論三個函數：ProRasterFileWrite，ProIntf3DFileWrite和ProPDFExport
這三個函數的共同特點是導出模型，具體有所不同。ProRasterFileWrite導出圖片；ProIntf3DFileWrite則側重與各種三維圖形格式的轉換；ProPDFExport則把模型導出為PDF格式文件。
（1）ProRasterFileWrite
ProRasterFileWrite函數定義如下：
| ProError | ProRasterFileWrite | ( |
| int window_id | ||
| /* (In) | ||
| 導出窗口ID,當前窗口用ProWindowCurrentGet獲得 | ||
| */ | ||
| ProRasterDepth depth | ||
| /* (In) | ||
| 像素類型：PRORASTERDEPTH_8；PRORASTERDEPTH_24 | ||
| */ | ||
| double width | ||
| /* (In) | ||
| 圖片寬度多少 inches | ||
| */ | ||
| double height | ||
| /* (In) | ||
| 圖片寬度多少 inches | ||
| */ | ||
| ProDotsPerInch dots_per_inch | ||
| /* (In) | ||
| 每個英寸多少像素PRORASTERDPI_100 = 100, PRORASTERDPI_200 = 200, PRORASTERDPI_300 = 300, PRORASTERDPI_400 = 400, PRORASTERDPI_500 = 500, PRORASTERDPI_600 = 600 | ||
| */ | ||
| ProRasterType type | ||
| /* (In) | ||
| 圖形格式：PRORASTERTYPE_BMP, PRORASTERTYPE_TIFF, PRORASTERTYPE_EPS, PRORASTERTYPE_JPEG | ||
| */ | ||
| ProPath output_file | ||
| /* (In) | ||
| 文件名稱，包含擴展名 | ||
| */ | ||
| ) | ||
這個函數用法很簡單，就是把當前窗口打印出來，可以生成幾種不同的圖形格式：PRORASTERTYPE_BMP, PRORASTERTYPE_TIFF, PRORASTERTYPE_EPS, PRORASTERTYPE_JPEG。當然也可以用-1來代表當前窗口ID。
int id; ProWindowCurrentGet(&id); ProRasterFileWrite(id,PRORASTERDEPTH_24,100,100,PRORASTERDPI_100, PRORASTERTYPE_JPEG,L"out.jpeg"); 或者 ProRasterFileWrite(-1,PRORASTERDEPTH_24,100,100,PRORASTERDPI_100, PRORASTERTYPE_JPEG,L"out2.jpeg");
當然也可以根據模型handle來獲取窗口：ProMdlWindowGet ( ProMdl mdl, int* window_id );
（2）ProIntf3DFileWrite
ProIntf3DFileWrite可以將模型導出成如下格式：
|
|
|
Type Constant |
|---|---|---|
函數定義如下:
| ProError | ProIntf3DFileWrite | ( |
| ProSolid solid | ||
| /* (In) | ||
| The solid model used for export. | ||
| */ | ||
| ProIntf3DExportType file_type | ||
| /* (In) | ||
| The type of output file to produce. | ||
| */ | ||
| ProPath output_file | ||
| /* (In) | ||
| The output file name to produce. Optionally, this includes the path for the file location. The filename should not include the file extension, this will be added automatically by Pro/ENGINEER. | ||
| */ | ||
| ProOutputAssemblyConfiguration configuration | ||
| /* (In) | ||
| Specifies the number and type of output files to produce. Users should check that this option is valid for the type of output specified in file_type by using the function ProOutputAssemblyConfigurationIsSupported(). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this value is ignored by Pro/ENGINEER. | ||
| */ | ||
| ProSelection reference_csys | ||
| /* (In) | ||
| The reference coordinate system. If NULL, the system uses the default coordinate system. If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputBrepRepresentation brep_representation | ||
| /* (In) | ||
| The options that specify the type of representation to create. Users should check that these options are valid for the type of output specified in file_type by using the function ProOutputBrepRepresentationIsSupported(). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputInclusion inclusion | ||
| /* (In) | ||
| The options for entity inclusion or exclusion in the output file(s). If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
| ProOutputLayerOptions layer_options | ||
| /* (In) | ||
| The options that specify how layers are to be output. If file_type == PRO_INTF_EXPORT_CADDS or PRO_INTF_EXPORT_NEUTRAL, this should be NULL. | ||
| */ | ||
幾點注意事項:
參數ProIntf3DExportType定義導出類型,有下面幾種:
typedef enum pro_intf3d_export_type {
PRO_INTF_EXPORT_STEP = 1,
PRO_INTF_EXPORT_SET,
PRO_INTF_EXPORT_VDA,
PRO_INTF_EXPORT_IGES,
PRO_INTF_EXPORT_CATIA,
PRO_INTF_EXPORT_CATIA_MODEL,
PRO_INTF_EXPORT_SAT,
PRO_INTF_EXPORT_NEUTRAL,
PRO_INTF_EXPORT_CADDS,
PRO_INTF_EXPORT_CATIA_SESSION, /* Not currently supported; */
/* reserved for future use. */
PRO_INTF_EXPORT_PDGS, /* Not currently supported; */
/* reserved for future use. */
PRO_INTF_EXPORT_PARASOLID,
PRO_INTF_EXPORT_UG,
PRO_INTF_EXPORT_RESERVED,
PRO_INTF_EXPORT_CATIA_PART,
PRO_INTF_EXPORT_CATIA_PRODUCT
} ProIntf3DExportType;
請注意這個參數:ProOutputAssemblyConfiguration configuration
它定義了裝配導出后的性質,可以將整個裝配體定義為一個PART，或者將裝配所包含的所有部件逐一導出，詳細解釋：
PRO_OUTPUT_ASSEMBLY_FLAT_FILE：表示將ASM當作PART處理，導出后整個ASM模型合並成一個PART。
PRO_OUTPUT_ASSEMBLY_SINGLE_FILE：將ASM文件導出，引用其其現有組成部件。
PRO_OUTPUT_ASSEMBLY_MULTI_FILES：將ASM文件導出，將其現有組成部件也一起逐個導出。
PRO_OUTPUT_ASSEMBLY_PARTS
可以用ProOutputAssemblyConfigurationIsSupported判斷ProOutputAssemblyConfiguration是否對當前模型適應。
ProOutputBrepRepresentation brep_representation：如何表示導出的幾何體，當作線，面或者體
先用ProOutputBrepRepresentationAlloc制造一個ProOutputBrepRepresentation
然后調用函數進行設置：
ProOutputBrepRepresentationFlagsSet(rep,
PRO_B_FALSE,//ProBoolean as_wireframe,
PRO_B_FALSE,//ProBoolean as_surfaces,
PRO_B_TRUE,//ProBoolean as_solid,
PRO_B_FALSE//ProBoolean as_quilts
);
結束后釋放內存：ProOutputBrepRepresentationFree
ProOutputInclusion inclusion：規定一些輔助線，坐標系是否導出
用這個函數進行設置：ProOutputInclusionFlagsSet(lnc,
PRO_B_TRUE,//ProBoolean include_datums,
PRO_B_FALSE,//ProBoolean include_blanked,
PRO_B_FALSE//ProBoolean include_facetted
);
最好放掉內存：ProOutputInclusionFree
一個簡單的例子如下：將當前的PRT或者ASM導出為.ps(PARASOLID)格式。
ProMdl mdl; ProOutputBrepRepresentation rep; ProOutputBrepRepresentationAlloc(&rep); ProOutputBrepRepresentationFlagsSet(rep, PRO_B_FALSE,//ProBoolean as_wireframe, PRO_B_FALSE,//ProBoolean as_surfaces, PRO_B_TRUE,//ProBoolean as_solid, PRO_B_FALSE//ProBoolean as_quilts ); ProBoolean pb; //檢查輸出選項是否支持 ProError er=ProOutputBrepRepresentationIsSupported(PRO_INTF_EXPORT_PARASOLID, rep,&pb); if (er!=PRO_TK_NO_ERROR||!pb) { AfxMessageBox("Not Support!"); return; } ProOutputInclusion lnc; ProOutputInclusionAlloc(&lnc); ProOutputInclusionFlagsSet(lnc, PRO_B_TRUE,//ProBoolean include_datums, PRO_B_FALSE,//ProBoolean include_blanked, PRO_B_FALSE//ProBoolean include_facetted ); ProOutputLayerOptions lop; ProOutputLayerOptionsAlloc(&lop); ProOutputLayerOptionsAutoidSet(lop, PRO_B_FALSE//auto_ids ); //當前PRT 或者 ASM ProMdlCurrentGet(&mdl); if (!mdl) { AfxMessageBox("no prt or asm avaiable"); return; }
//導出 ProIntf3DFileWrite((ProSolid)mdl, PRO_INTF_EXPORT_PARASOLID,//導出ps格式 L"new_ps_name",//不要帶后綴名，會自動加上去 PRO_OUTPUT_ASSEMBLY_FLAT_FILE,//將ASM當作一個PART處理導出 NULL, rep, lnc, lop ); ProOutputBrepRepresentationFree(rep); ProOutputInclusionFree(lnc); ProOutputLayerOptionsFree(lop);
模型文件：
導出PS格式后：
（3）導出PDF文件
需要包含頭文件#include <ProPDF.h>
主要函數有這么幾個：
- ProPDFoptionsIntpropertySet()：設置int型參數值
-
ProPDFoptionsAlloc() ：產生一個ProPDFOptions對象，后面的屬性設置和導出都需要ProPDFOptions作為輸入
主要的屬性對象如下：
typedef enum { PRO_PDFOPT_FONT_STROKE, /* Enum, ProPDFFontStrokeMode, default PRO_PDF_USE_TRUETYPE_FONTS */ PRO_PDFOPT_COLOR_DEPTH, /* Enum, ProPDFColorDepth, default PRO_PDF_CD_COLOR */ PRO_PDFOPT_HIDDENLINE_MODE, /* Enum, ProPDFHiddenLineMode, default PRO_PDF_HLM_DASHED */ PRO_PDFOPT_SEARCHABLE_TEXT, /* Boolean, default TRUE */ PRO_PDFOPT_RASTER_DPI, /* Int, Range 100 - 600, default 300 */ PRO_PDFOPT_LAUNCH_VIEWER, /* Boolean, default TRUE */ PRO_PDFOPT_LAYER_MODE, /* Enum, ProPDFLayerMode, default PRO_PDF_LAYERS_ALL */ PRO_PDFOPT_PARAM_MODE, /* Enum, ProPDFParamMode, default PRO_PDF_PARAMS_ALL */ PRO_PDFOPT_HYPERLINKS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_ZONES, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_VIEWS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_SHEETS, /* Boolean, default TRUE */ PRO_PDFOPT_BOOKMARK_FLAG_NOTES, /* Boolean, default TRUE */ PRO_PDFOPT_TITLE, /* String, default "" */ PRO_PDFOPT_AUTHOR, /* String, default <current user name> */ PRO_PDFOPT_SUBJECT, /* String, default "" */ PRO_PDFOPT_KEYWORDS, /* String, default "" */ PRO_PDFOPT_PASSWORD_TO_OPEN, /* String, default NULL, which means that the document may be opened by anyone */ PRO_PDFOPT_MASTER_PASSWORD, /* String, default NULL, which means that anyone may perform any change regardless of any of the modification flags PRO_PDFOPT_ALLOW_* listed below */ PRO_PDFOPT_RESTRICT_OPERATIONS, /* Boolean, default FALSE set to TRUE to use PRO_PDFOPT_ALLOW_* to use ProPDFRestrictOperationsMode */ PRO_PDFOPT_ALLOW_PRINTING, /* Boolean, default TRUE */ PRO_PDFOPT_ALLOW_PRINTING_MODE, /* Enum, ProPDFPrintingMode, default PRO_PDF_PRINTING_HIGH_RES */ PRO_PDFOPT_ALLOW_MODE, /* Enum, ProPDFRestrictOperationsMode, default PRO_PDF_RESTRICT_NONE */ PRO_PDFOPT_ALLOW_COPYING, /* Boolean, default TRUE */ PRO_PDFOPT_ALLOW_ACCESSIBILITY /* Boolean, default TRUE allows visually impaired screen reader devices to extract data independent of RestrictOperationsMode */ } ProPDFOptionType;
示例代碼如下：
ProPDFOptions ops; ProPDFoptionsAlloc(&ops); //use ProPDFoptionsBoolpropertySet() and ProPDFoptionsStringpropertySet() //to set property //............... ProMdl mdl; ProMdlCurrentGet(&mdl); if (!mdl) { AfxMessageBox("no prt or asm avaiable"); return; } ProPDFExport(mdl,L"obj.pdf", ops); ProPDFoptionsFree(ops);
