Hi,
I'm generally working with OpenRail Designer but this is not a rail specific problem.
The problem is as follows: We have made a 3D model of a train station with the help of several other planners. Our model includes rails, sleepers, etc. but also platforms and other objects. This is to say we have a mixture of meshes and volumes in our model. Now our goal is to visualise the construction process. When which turnout is deconstructed when it is rebuilt and so on for every element in the model. This is intended to be done with OpenBuilding Designer and attributes. The difficulty now is to get from the big model to the cut up (according to construction phases) model. These individual parts should retain their respective volume information so that later one can read out the information of materials per construction phase.
We have tried it by making a named boundary around a test part and doing a quantities report by named boundary while displaying that named boundary only, then we've made a saved view, which we then attached to a new empty file and finally merged that saved view into master. This seemed to mostly work until we merged the saved view into master. The mesh of our ballast had created new lines and connections with itself and also lines that went into nothing. It slightly resembeld the chaotic paintings I would make whith paint when I was bored when I was younger. The volume information also seemed to be lost.
I've attached a result of the excercise for those interested.
I'm hopeful some of you might help weed out the problems in our approach or maybe even provide a different approach, as long as it works.

Create an empty file, bring in your references, set an active terrain then:
1- First you need to create a named boundary from an objet (place a shape then in the named boudary dialog choose from object)
2- Then you use the quantity from named boundary and you click the "Display cliped graphics"
Openroads will then merge your 3D model but only in this shape.
You now have a file consisting of only your model in this phase

Thank you for your quick answer!
I tried it and it worked at least partially. For one you mention an active terrain, in my test file I don't have one - is it necessary to have one?
Second not all meshes were merged with the new file. So the chaotic is no more but now some meshes are missing. I notice that those are all older meshes, there might be something wrong with those I'll have to further test it out.
Thanks again!
No you don't need a terrain, it's just to create the associated 3D Default Model to the 2D default model. You do your 2D shape in your default 2D model. As for the mesh not coming along, try updating your different file by opening them with your current version (should be the last one 2020R2 as there was some bug in a previous one)
Ah yes, since I have geometry I had just used that to get a 3D Model. I've found that the older meshes don't have a feature definition assigned and don't work because of that, since when I assign a feature definition the meshes are recognized.
Probably when there is no feature definition it can't form a report of it and in turn can't include it in the named boundary cut.
