Onuma to Revit 2010


ONUMA, Inc. is committed to open standards exchanges. At the same time we want to give access to other options. So, we created a plugin for Revit 2010 that manages spaces to the furniture and equipment level. This added functionality allows you to enjoy a rapid planning & design process using Revit 2010 and Onuma. Keep in mind since you are only dealing with SPACES, SLABS and EQUIPMENT in Onuma, you can very quickly test numerous schemes in Onuma before exporting to Revit and modeling the more detailed components such as doors, windows, roofs, etc. Your building is also available in a wide variety of other file formats in Onuma.

Onuma Revit 2010 Plugin Advanced Features

Wall Choice
  • Now when importing a building from Onuma into Revit you can now choose between:
    • Room Separation Lines OR
    • Walls
      NOTE: Walls are inserted on the center line and as such reduce your space area, to maintain area, please select room separation lines.

Import of Space Attributes

  • When importing a building from Onuma into Revit, all space attributes are inserted into the Revit model as well. You can even create color schemes for the plans in Revit that are based on the same attributes as the color schemes in Onuma. When updating (see below) a model in Revit with a re-exported file from Onuma, you can update all space attributes that changed in Onuma.

Updating Feature

  • There are two BIMXML Imports in Onuma:
    • Site Plan level import creates a New Building (same as our 2009 plugin)
    • Building Plan level import Updates a building with any changed spatial information (floors, spaces, furniture, placement, size, rotation, etc.) from the Revit model
      • Updating can only be done with the same building (i.e. a building previously exported from Onuma; obviously, the building can also originate in Revit, then imported into Onuma, then again exported to Revit (updating the Revit model - see above) and then again updating the building in Onuma. You can go many times back and forth as long as it is the same building, i.e. floors, spaces, and furniture have the same Global Unique ID (GUID).
      • When you edit a scheme in Onuma and take that to update a Revit building ONLY attributes and newly added spaces will update in Revit -- you can not update furniture or area in Onuma to Revit.
      • When you edit a Revit building and take that to update an Onuma scheme ONLY area, furniture and newly added spaces will update in Onuma -- you can not update attributes in Revit to Onuma.
