Get ObjectId

DRossger — Thu, 28 Mar 2019 16:21:08 GMT

Hello!

Can somebody explain how to get ObjectId without an object ?

I want create a Pipe in Civil3D as I found it here:

https://knowledge.autodesk.com/support/civil-3d/learn-explore/caas/CloudHelp/cloudhelp/2015/ENU/Civil3D-DevGuide/files/GUID-6A41C6B7-3640-4F47-8125-60117A5DD1DF-htm.html

but I have some trouble with "AddLinePipe", method want a parameter in method

oNetwork.AddLinePipe(oid, psize, line, ref oidNewPipe, false); what means that ?

oidNewPipe is well NULL or ....

That means oidNewPipe after calling oNetwork.AddLinePipe will be setting to ObjectId of new created and added to Database Pipe. See example in your URL reference.

Yes I read it and test sample code-snippet but exactly in this AddLinePipe-method I get an exception

ex = {"Fail to add line pipe."}

because oidNewPipe is empty or NULL. How works ref, maybe I do it wrong ?

Is it possible to create ObjectId without object ?

Sorry but it is look like you wrong. Method AddLinePipe have to fill oidNewPipe. So you have not initialize oidNewPipe other then ObjectId.Null.

Exception can be thrown because of other problems with your code.
