View settings from Revit into Navisworks

There are various ‘view settings’ which are transferred through from Revit into Navisworks that you may not be aware of:

  • View control bar – Detail level
    When exporting your Revit model to Navisworks, pay attention to the detail level which is set. If your model is on ‘Course’ detail, elements such as pipes will show up as lines rather than 3D pipes as you would see in Revit.
  • Hidden objects / elements
    Items which are hidden but not applied to the view will still be visible in Navisworks. However, if you apply your hide / isolate elements to the view, Navisworks will remember these settings and omit any elements hidden and applied.
  • Visibility Graphics Overrides
    Items which are turned off in Visibility/Graphic Overrides will be applied in your Navis view. For example, if you have your Ducts category turned off in your Revit project via ‘VG’ these will also be turned off in Navisworks when exporting to an .NWC
  • Worksets
    Worksets which are hidden or turned off in your Revit model will not be brought through into your Navisworks project. Ensure that all applicable worksets are turned on before exporting to .NWC
  • Model lines in Revit
    Model lines will not be shown in your 3D Navisworks file when brought through from your Revit project. One way to combat this would be to export your Revit file as an .IFC and then bring that file into Navisworks. .IFC brings through model lines but not detail lines through the { IfcAnnotation } Parameter.
  • Section box
    If you have a section box on your model when you export to .nwc only items within the section box will be exported. All other geometry outside of this sectioned view will be hidden in Navisworks as it will be in Revit.

Find the position of real world coordinates

Are you looking to find the eastings and northings points for a specific location in the UK?

Here is a good way to roughly check the coordinated location of a Revit project in the UK. The website UK Grid Reference Finder is an excellent website to use to cross check that your model is situated in roughly the correct coordinate system. You can search either by location, Eastings and Northings points or longitude and latitude.

find coordinates

This tool should be used with consideration as it will not give you a completely accurate reading, but can be used to double check the coordinates of others models when you are having issues with models aligning through shared coordinates.

Naviswork Switchback with Revit

Trying to find those saved viewpoints from Navisworks in your Revit model?

Navisworks switchback is an excellent and very simple tool to use, to find referring views from Navisworks in your Revit project.

When making issue reports / clash views it is sometimes difficult to find the same referring view in your Revit project – Navisworks Switchback makes this seamless. Below is a short video showing how it works.

If you are using someone elses model you may find that you may need an additional step of locating the Revit model as the original file is being referenced from the authors server – Simply browse for your local version of the Revit model.

PAS1192-3 Draft released for public consultation

PAS1192-3 Has been released for public consultation today, sponsored by CIC and available to download on the BSI website here

This PAS specifies requirements for achieving BIM Level 2 in relation to the operation and maintenance of assets (buildings and infrastructure).

It covers the data transfer processes to inherit asset information from the project information model (PIM) or to create an asset information model (AIM) for an existing asset or portfolio of assets, to use it to support organizational requirements, to revise it as the asset changes, and to hold it as a resource for the owners, operators and maintainers of the asset.

This PAS does not cover data content but does cross-refer to broad headings and documents which define data content.

This PAS is for use by organizations and individuals responsible for the operation, maintenance and strategic management of assets. In particular, it is of use to individuals involved in transferring data from the PIM to an AIM utilised by the organization.

NOTE An organization may apply this PAS without necessarily needing to use BIM Level 2. However, an organization required to apply BIM Level 2 to the operational phase of an asset would need to apply this PAS.
