jig 一次插入多个块
namespace blockjig
{
public class blockjig:entityjig
{
point3d mcenterpt, mactualpoint;
public blockjig(blockreference br)
: base(br)
{
mcenterpt = br.position;
}
protected override samplerstatus sampler(jigprompts prompts)
{
jigpromptoptions jigopts = new jigpromptoptions();
jigopts.userinputcontrols =
(userinputcontrols.accept3dcoordinates
| userinputcontrols.nozeroresponseaccepted
| userinputcontrols.nonegativeresponseaccepted);
jigopts.message = "\nenter insert point:";
promptpointresult dres = prompts.acquirepoint(jigopts);
if (mactualpoint == dres.value)
{
return samplerstatus.nochange;
}
else
{
mactualpoint = dres.value;
}
return samplerstatus.ok;
}
protected override bool update()
{
mcenterpt = mactualpoint;
try
{
((blockreference)entity).position = mcenterpt;
}
catch (system.exception)
{
return false;
}
return true;
}
public entity getentity()
{
return entity;
}
[commandmethod("insertblocksample")]
public void insertentitybypickpoint()
{
string blockpath = @"c:\program files\autocad , openmode.forwrite);
btr.appendentity(entjig.getentity());
tr.addnewlycreateddbobject(entjig.getentity(), true);
doc.transactionmanager.queueforgraphicsflush();
}
isfirstinsert = false;
}
tr.commit();
}
}
}
}
}
}
为什么运行刚输入命令就报有致命错误。环境是vs
public void insertentitybypickpoint()
{
string blockpath = @"c:\program files\autocad , openmode.forwrite);
btr.appendentity(entjig.getentity());
tr.addnewlycreateddbobject(entjig.getentity(), true);
doc.transactionmanager.queueforgraphicsflush();
}
isfirstinsert = false;
}
tr.commit();
}
}
}
}
}
}
这样子貌似就可以了 烦恼自己调试一下子看看
