关于arx中的尺寸

web.pawan · 发表于 2009-12-23 04:09:37

亲爱的成员们，
任何人都知道如何在arx中创建维度
在autolisp中，我将使用_。dimaligned

(setq  pt1 (list 5 5))
(setq  pt2 (list 10 10))
(command "line" pt1 pt2        "")
(command "_.dimaligned" pt1 pt2         (polar pt2 0  1))

带有代码的简单示例会很好workingDatabase();
AcDbBlockTableRecordPointer pBlockTableRecord(pDatabase->currentSpaceId(),AcDb::kForWrite);
AcDbAlignedDimension *dim = new AcDbAlignedDimension (pr1.Point,pr2.Point,pr3.Point);
dim->setDatabaseDefaults(pDatabase);
pBlockTableRecord->appendAcDbEntity(dim);
dim->close();
}
[/code]

你好Daniel，
我使用了你之前的代码，只是修改了一些以使用我的数据库。
以下代码在autocad中抛出错误对话框。
是否有我丢失的东西？如果我使用workingDatabase，它不会报告此错误。
关于，
Pawan

copy

int test_save()
{
        AcDbDatabase *pDb = new AcDbDatabase();
        AcDbBlockTable *pBtbl;
        pDb->getSymbolTable(pBtbl, AcDb::kForRead);
        AcDbBlockTableRecord *pBtblRcd;
        pBtbl->getAt(ACDB_MODEL_SPACE, pBtblRcd, AcDb::kForWrite);
        pBtbl->close();
        ////////////////dim starts
        ads_point pt1 = {5,10};
        ads_point pt2 = {15,10};
        ads_point pt3 = {10,10};
        ads_point temp = {10,10};
        ads_real tAngle = 0;
        AcGePoint3d stpt(asPnt3d(pt1)); //3d starting point
        AcGePoint3d endpt(asPnt3d(pt2));; //3d ending point
        acutPolar(pt3, tAngle, 0, temp);
        AcGePoint3d dimPoint(asPnt3d(temp)); //3d dim point
 
//    if i use working database, this doesn't give error
//    AcDbDatabase *pDb= acdbHostApplicationServices()->workingDatabase();
//    AcDbBlockTableRecordPointer pBtblRcd(pDb->currentSpaceId(),AcDb::kForWrite);
   
        AcDbAlignedDimension *dim = new AcDbAlignedDimension (stpt,endpt,dimPoint);
        dim->setDatabaseDefaults(pDb);
        pBtblRcd->appendAcDbEntity(dim);
        dim->close();
        ////////////////dim ends
        
        //close the blocktable record
        pBtblRcd->close();
        //save the file
        Acad::ErrorStatus es = pDb->saveAs(_T("c:\\temp\\test.dwg"));
        //delete the database
        delete pDb;
        return 0;
