[每日一码] （7）在ARX里模拟INSERT命令实现代码替代acedCommand调用的解决方案
//----- Read the external DWG fileAcDbDatabase *pDwg =new AcDbDatabase (Adesk::kFalse) ;
pDwg->readDwgFile (采用T("c:\\drawing1.dwg")) ;
//----- Put it into a block table record of the current database
AcDbObjectId id ;
Acad::ErrorStatus es = acdbHostApplicationServices()->workingDatabase()->insert(id, 采用T("drawing1"), pDwg, Adesk::kFalse) ;
if ( es != Acad::eOk )
acutPrintf (采用T("\nError inserting a block.")) ;
delete pDwg ;
As soon as you have a block table record in place you can add an AcDbBlockReference with it. The block reference is the INSERT'ed block table record instance that is displayed in the model or paper space. The below example shows how to create a block reference with attributes from a block table record. You can call it following above code like this:
AcGePoint3d point3D(0,0,0);
addBlockWithAttributes(id,point3D);
//NOTE: You will have to update the code to properly set the attribute values. The code below sets the value of each attribute to "XXX".
static void addBlockWithAttributes (AcDbObjectId blockId, AcGePoint3d basePoint) {
//----- Step 1: Allocate a block reference object
AcDbBlockReference *pBlkRef =new AcDbBlockReference ;
//----- Step 2: Set up the block reference to the newly
//----- created block definition
pBlkRef->setBlockTableRecord (blockId) ;
//---- Give it the current UCS normal.
pBlkRef->setPosition (basePoint) ;
pBlkRef->setRotation (0.0) ;
pBlkRef->setNormal (AcGeVector3d (0.0, 0.0, 1.0)) ;
//----- Step 3: Open current database's Model Space
//----- blockTableRecord
AcDbBlockTable *pBlockTable ;
acdbHostApplicationServices()->workingDatabase()->getBlockTable (pBlockTable, AcDb::kForRead) ;
AcDbBlockTableRecord *pBlockTableRecord ;
pBlockTable->getAt (ACDB采用MODEL采用SPACE, pBlockTableRecord,
AcDb::kForWrite) ;
pBlockTable->close () ;
//----- Append the block reference to the model space
//----- block table record
AcDbObjectId newEntId ;
pBlockTableRecord->appendAcDbEntity (newEntId, pBlkRef) ;
pBlockTableRecord->close () ;
//----- Step 4: Open the block definition for read
AcDbBlockTableRecord *pBlockDef ;
acdbOpenObject (pBlockDef, blockId, AcDb::kForRead) ;
AcDbBlockTableRecordIterator *pIterator ;
pBlockDef->newIterator (pIterator) ;
AcDbEntity *pEnt ;
AcDbAttributeDefinition *pAttdef ;
for ( pIterator->start () ; !pIterator->done() ; pIterator->step () ) {
//----- Get the next entity
pIterator->getEntity (pEnt, AcDb::kForRead) ;
//----- Make sure the entity is an attribute definition
//----- and not a constant
pAttdef =AcDbAttributeDefinition::cast (pEnt) ;
if ( pAttdef != NULL && !pAttdef->isConstant () ) {
//----- We have a non-constant attribute definition
//----- so build an attribute entity
AcDbAttribute *pAtt =new AcDbAttribute ;
pAtt->setPropertiesFrom (pAttdef) ;
pAtt->setInvisible (pAttdef->isInvisible ()) ;
//----- Translate attribute by block reference.
//----- To be really correct, entire block
//----- reference transform should be applied here.
basePoint =pAttdef->position () ;
basePoint +=pBlkRef->position ().asVector () ;
pAtt->setPosition (basePoint) ;
pAtt->setHeight (pAttdef->height ()) ;
pAtt->setRotation (pAttdef->rotation ()) ;
pAtt->setTag (采用T("Tag")) ;
pAtt->setFieldLength (25) ;
TCHAR *pStr =pAttdef->tag () ;
pAtt->setTag (pStr) ;
delete pStr ;
pAtt->setFieldLength (pAttdef->fieldLength ()) ;
//----- Database Column value should be displayed
//----- INSERT would prompt for this...
pAtt->setTextString (采用T("XXX")) ;
//----- Set Alignments
pAtt->setHorizontalMode( pAttdef->horizontalMode ()) ;
pAtt->setVerticalMode (pAttdef->verticalMode ()) ;
pAtt->setAlignmentPoint (
pAttdef->alignmentPoint ()
+ pBlkRef->position ().asVector ()
) ;
//----- Insert the attribute in the DWG
AcDbObjectId attId ;
pBlkRef->appendAttribute (attId, pAtt) ;
pAtt->close () ;
}
pEnt->close () ; //----- Use pEnt... pAttdef might be NULL
}
delete pIterator ;
pBlockDef->close () ;
pBlkRef->close () ;
}
