Elbow rotated in isometric and lost proper connection

[hamid.TCAD]

When I create an elbow rolled, the elbow will be rotated in isometric and lost the connection making the isometric completely useless. I am not sure if there is problem in my model or any setting, but I tried different way of modeling. This happens also when I model it even without rolled elbow and just to select a direction not aligned with X or Y axis for the pipe, in this example for horizontal pipe which is not aligned with X Y axis. I appreciate anyone can help.

Anyone has idea about this issue?

@hamid.TCAD check the coordinates of your model, they must be very far from the origin (0,0). Also, try to model your plant using the WCS.

To resolve this, move your model closer to 0,0. Now, to get the accurate coordinates in your isometrics, go to project setup, Iso Style Default Setting to apply the offset value to your new coordinates

Thank you Mj_Dan, 

That resolved the issue completely.

Now I see all connections in the model gone. I have to select one by one and run "Connected to Adjacent". They are not huge numbers, but for some of them, isometrics have been created and issued to the client that makes me a bit concerned. Is there any way that we can keep all parts connected when we move them?

The solution provided here, although effective in its own way, I don't think reflects the reality of the reason many projects are oriented significant distances from the origin. We have several mining customers that have sites spanning distances of dozens of kilometers, each with 3D model turn-over requirements that drive us to model in coordination with each customers defined plant coordinate system, which often has a singular origin located at a convenient UTM intersection. Generally this doesn't usually cause many issues. In fact, we have a current project where we've integrated customer supplied Autocad and Navisworks models, inserted our own laser scan data using Recap, incorporated piping, structural, electrical and equipment models all together, all centered around a point over 50km from the origin, with project units in millimeters. In this entire project, the only issue we've detected as a result of this offset from origin is the rolled elbow that can't calculate its three points correctly (even a 16" elbow, so we're not talking about 1/4" tubing here where the coordinates are that much closer together), resulting in a disconnected looking isometric. Perhaps Autodesk can have someone take another look at this issue to see if the isometric functions for displaying these elbows can be revisited to accommodate users requirements to meet their customers needs. Simply offsetting the plant opens an entire other can of worms for which I don't think we have much of an appetite.

I have the same issue.

Is there any update regarding this case?
