[Pin to top] C # insert another DWG graph block in CAD

1. In the cad2012 environment:

ObjectARX development kit must be referenced

Promptpointresult PPR = ed. getpoint ("Select Insert point :");

Point3d Pt = PPR. value; // The insert point is obtained here.

Utility. writetoeditor (Pt. tostring ());

Blockpath = "B _sample.dwg ";
Using (Database blkdb = new database (false, true ))
{

// Read drawing

Blkdb. readdwgfile (blockpath, system. Io. fileshare. Read, true, null );

Blkdb. closeinput (true );

Using (documentlock doclock = Doc. lockdocument () // This is required for multiple documents first; otherwise, an error is returned.

{

Using (transaction T = Doc. transactionmanager. starttransaction ())

{
String name = "AA"; // AA is a string that does not have the same name as any block in the blockpath file.
// Insert it as a new block

Objectid idbtr = Doc. database. insert (AA, blkdb, false );

// Create a ref to the block

Blocktable bt = (blocktable) T. GetObject (Doc. database. blocktableid, openmode. forread );

Blocktablerecord BTR = (blocktablerecord) T. GetObject (BT [blocktablerecord. modelspace], openmode. forwrite );

Using (blockreference BREF = new blockreference (PT, idbtr) // PT is a point3d coordinate, which is inserted into the current DWG file.

{

BTR. appendentity (BREF );

T. addnewlycreateddbobject (BREF, true );

}

T. Commit (); that's it. Thank you.
}
}
}
