Missing components in Assembly Drawing

[ebuckner]

I am working on a large plant piping project and while I've seen this behaviour before I've never seen it this bad.

Attached is a screen shot of a small portion of the assembly drawing in which you can see a good example of what I'm dealing with.

At the top you can see a weld neck flange that appears to be attached to air where there should be an elbow.

In the middle you can see that on one side of the elbow there is missing geometry.

At the bottom is another flange that attached to air where there should be an elbow.

this drawing is littered with these errors and as such is unsuitable for even a reference document.

I have turned visibility of these components off and on without resolution.

I have turned on tangent and interference edges without resolution.

I have translated a copy to ACAD to see if it's simply graphical but the ACAD file shows the same errors.

I have checked parallel and perpendicularity and all is well.

Does anyone have a cause or solution to this issue?

Hi Eric,

do you experience the problem on other machine as well? (if you have chance to try it).

Could you create a simplified assembly which can still reproduce the problem in drawing and send it to me? (my email: <nickname>@autodesk.com)

I'd like to take a look.

Thanks,

Jozef

I have seen the same thing on 2 computers, buiult at different times.

Yes, once a view is created with errors that same view will have the same errors on other machines.

I will attempt to recreate the erros on one portion of the assembly.
