topolgy correctness information

[Anonymous]

Hi,

I have to access topologies in a lot of DWG-s. But there are some DWGs where one or more topolgies can be incorrect (for example, duplicated topology IDs). How can I get information about topology correctness - in program? Now I open - and close, of course - topologies and if one topologies is incorrect, the AutoCAD is crashed when I try to open it.

C++, ObjectArx, AutoCAD Map 3D 2010 (or higher)

AcMapTopology	topo(strTopoName);
AcMap::EErrCode	err = AcMap::kOk;
try
{
	err = topo.Open(AcMapTopology::eForRead);
}
catch (...)
{
	//	...
}

Hi,

Did you check this ?

TopologyModel:: IsComplete Property -> Gets whether this topology model is complete.

In Map 3D SDK, you will get to see API samples on Topology feature.

Hope this helps.

Thanks,

Hi,

Thank you your answer.

Yes, I checked before AcMapTopology::IsComplete, but it was always false before open.

I saw the samples, but in ObjectARX Map 2010 Topology samples it always openes the topology, before use it.

Or I missed something?
