  1. Can 2022 not be installed silently?
  2. Do you know where the internal origin is in Vectorworks? This chap... It's the centre of the model, where X, Y and Z are 0. Revit has one. So does SketchUp. And so does Rhino. In order to fully coordinate your Vectorworks model with someone using Revit, first make sure your origin and their origin are in the same place relative to the model itself. Model = 3D data either solids, NURBS or BIM. Matters not. Any 3D data = model.
  3. Next installment of the VW > Revit discussion... I feel like Charles Dickens. ALL MODELS MUST HAVE A COMMON ORIGIN!!! and by this I mean that all models (and when I say ‘all models’ I mean models from vw, rvt, SKP, 3dm, etc) must be aligned to the same internal origin BEFORE you apply any user origins, project base points or any other applied coordinate system. if your internal origins are not aligned and are not in the same place relative to the model YOU ARE NOT COORDINATED irrespective of the ‘shared coordinate system’. In order to do this you must not use the recommended DWG import settings in Vectorworks. You must manage the process, set you user origin manually, and create a template for the project.
  4. For the same reason why everyone should not use Revit.
  5. A key thing to remember with IFC is that it has a specific purpose and does not behave like native software when imported into Revit, vectorworks or any other Bim software. To start with it contains little or no 2D data. this means unlike DWG you cannot import an IFC and produce a (traditional) drawing. A lot of line work often goes into making the drawing legible and complete in Revit (and Vectorworks) - Grids etc - and therefore you need to also request to the DWG data from model space to be able to use this for coordination in addition to IFC. A lot of 2D data that might ordinarily be part of a 3D object like a door swing can go missing or be reinterpreted in the recipient software. to think that you are sharing IFC in order to a, produce a set of drawings or b, see the 2D content visible in native software is naive but it’s amazing how many times Revit and Vectorworks users complain that they are not able to produce a drawing with a sheet and annotation etc from an IFC. I had one express astonishment that the ubiquitous ’splash screen’ in Revit was omitted from the IFC. I nearly choked on my lunch that day.
  6. You need to establish very clear aims. What are you sharing information for? What do you really need to share in order to coordinate the design? Are you simply contributing to the set of 2-D drawings? Or are you actively engaged in a 3-D coordination process? Arguably unless there is a need to share in 3-D you don’t need to build a model to coordinate the design. You do though need coordinated 2D data and this means coordinated with the model as well as coordinated with all other 2D information.
  7. Hello @PatStanford yes I have some recommendations and suggestions. a good BEP helps. But the main issue is the Revit user themselves. if they know what they are doing with Revit and can give and receive IFC, it is fairly straightforward. like model setup there are rules when it comes to IFC and these should be defined in the BEP.
  8. Reimport the DWG as 3D and see if there are any 3D points or symbols in the file. Sometimes there are 3D symbols which you can drop in a 3D locus and then explode the symbol to get a set of 3D points from which to create a site model. failing that send me a vw file with the levels isolated. I have a script to convert the levels to a ‘survey points file’ as per @E|FA response above.
  9. Trying to decipher the definition given by BuildingSmart. it would appear to me, for example, that you use zones for a unique collection of spaces, such as a collection of rooms in an apartment, but you should not associate spaces in multiple apartments to the same zone, particularly when the apartments ie the zones, do not always share the same properties such as orientation.
  10. What is your understanding of an IfcZone? Are IfcZones supposed to be unique? For example, is it good practice to associate the same zone to two apartments (the apartment is a zone type) when the two apartments on different sides of the building?
  11. Where would I find instructions to carry out a silent installation of Vectorworks 2022 on a mixed platfrom network, i.e. a practice with both Macs and PCs, and multiple staff working from home? Thanks.
  12. Turn off the strings and model them. It’s called a custom stairs because you have to customise it!
  13. Easiest way to check is to right click on the row in the spreadsheet and choose select item from the pulldown menu. It will take you to the window in the model/file.
  14. It depends if you are using the window tool or not. If not and you use symbols, set up a custom record format with all the information you need in your schedule and associate the record format to the symbol.
  15. In the construction tab, yes. The lookup tables should be available for all components.
  16. User fields aren’t great either since they can easily vary from file to file and door to door! we need classification to map to COBie and this needs to be a consistent parameter in the component.
  17. It’s about consistency. All components need classification code not just walls so why is door and window different from wall?
  18. The same thing happened in 2D. As I said, there are them that follow the rules and there are them that don’t.
  19. IFC into VW is very much based on retaining fidelity of the incoming geometry. This is a good thing, in my opinion, and from my experience. Objects converted to native objects in Revit from IFC are not reliable, and invariably have to be remodelled natively. I would expect to do the same in ArchiCAD. Model exchange via IFC is not really about round-tripping, just as it is not about 2D drawing. IFC is a coordination file format. It is not an interoperable file format. I am not sure who's approach is right, other than I have seen objects I have issued as IFC, and do not expect to be edited, imported into Revit and edited, and then reissued leading to errors in coordination. If people followed the rules, perhaps it would work, but few do it seems.
  20. We currently use one of the User Fields for the Classification Reference, e.g. Ss_25_30_95 for Windows. This then feeds into 'Type'.'Category' in the COBie spreadsheet via the Data Manager. However, like the Wall, it would be useful to have a 'Cost Code Index' entry field for Doors and Windows for this field, or in the UK 'Classfication' or 'Specification Reference'.
  21. I think the line between modelling for the production of drawings, and modelling for coordination are blurred. If you need to show, for example, a tap in elevation, you could model it. However, you do not need to issue it for coordination. All I need is the space required to operate the tap to make sure I don't design something that impedes someone from operating the tap. Therefore the model needs to deliver at multiple levels. However, we tend to assume that what we model does both. As a consequence models get huge, filled with unnecessary information, like cable trays and their fixings at 1;1. I simply do not need to receive a model that detailed. I need to know what space the cable tray will occupy, and that's it, just as a consultant does not need to know the build up of my partitions. They just need to know there is a wall there.
