Now that we have geolocated<\/a> our BIM model, we can start working on our BIM-GIS integration. For the first part of this blog, I am going showcase the workflow of reading directly from the BIM file workspace as a source. For part two, I will demonstrate the workflow of using a geodatabase dataset created from the BIM File to Geodatabase geoprocessing tool. These two workflows will give us the foundation to build more complex workflows later on, but before we can start working with the Building layer, we need to understand a few key concepts.<\/p>\n"},{"acf_fc_layout":"sidebar","content":"

Key concepts<\/h2>\n

Floorplan layer\u2014A group layer that contains the floorplan plan layers (2.5D) including the footprint (2D).<\/p>\n

Building layer\u2014A composite layer that organizes the BIM file workspace by datasets (disciplines including Architectural, Structural, Piping, Mechanical, and Electrical), and each dataset is composed of a layer that represents the BIM File Multipatch feature class.<\/p>\n

BIM File to Geodatabase\u2014Imports the contents of one or more BIM file workspaces into a geodatabase feature dataset.<\/p>\n

Make Building Layer\u2014Creates a composite building layer from a dataset, usually from a BIM file workspace.<\/p>\n","image_reference":false,"layout":"standard","image_reference_figure":"","snippet":"","spotlight_name":"","section_title":"","position":"Center","spotlight_image":false},{"acf_fc_layout":"content","content":"

As a Geospatial user, I am starting to become familiar with BIM and have learned that not every user has the same data requirements. The client, engineer, architect, general contractor, or consultant may require access to different data from the BIM. For example, the general contractor needs access to certain layers or elements while other users, such as the BIM manager or client, need to see a comprehensive view of the data. Different design disciplines often create different parts of the model as individual BIM models. This means a single building may be made up of multiple BIM models.<\/p>\n"},{"acf_fc_layout":"content","content":"

Part 1: BIM file workspace as a source\u2013Basic<\/h2>\n

I received a request from the inspection team that they need to view the architectural elements of the building (excluding furniture) along with the solar panels and the emergency and security elements such as fire extinguishers, exit signs, and outlets from the building.<\/p>\n

To remove unneeded layers, complete the following steps:<\/p>\n

1. Drag the BIM file workspace to the scene.<\/p>\n

2. Select a layer or layers. Right-click the layer, and click the Remove<\/strong><\/p>\n

Remove the following layers:<\/p>\n

    \n
  • From the Architectural<\/strong> discipline, remove everything except the Floors, Stairs, Generic model, and Doors layers.<\/li>\n
  • From the Structure<\/strong> discipline, remove StructuralColumns and StructuralFraming.<\/li>\n
  • From the Electrical<\/strong> discipline, remove all the layers except TelephoneDevices, FireAlarmDevices, and LightFixtures.<\/li>\n
  • From the Mechanical<\/strong> discipline, remove all layers.<\/li>\n
  • From the Piping<\/strong> discipline, remove all layers.<\/li>\n<\/ul>\n

    3. Drag the Generic model layer from the Architectural<\/strong> discipline to the Electrical<\/strong><\/p>\n

    Now that we have the Building layer the way that we need it, we will see if we have elements that we would like to remove from our layers. After a quick inspection of the Generic model layer, we discover that it has additional elements that are outside of our requirements.<\/p>\n

    4. Right-click the Generic model layer and browse to the Properties<\/strong><\/p>\n

    The Layer Properties<\/strong> window will appear.<\/p>\n

    5. Browse to the definition query.<\/p>\n

    6. Click New Definition Query<\/strong>.<\/p>\n

    7. Turn on SQL<\/strong>.<\/p>\n

    8. Write the following query:<\/p>\n

    FamilyType = ‘MicroFingerprintReaderFlush’<\/p>\n

    9. Click Apply<\/strong>.<\/p>\n

    10 Click OK<\/strong>.<\/p>\n

    Repeat steps 4 to 10 for the LightingFixtures layer using the following query:<\/p>\n

    FamilyType = ‘LPX7-Green Letters- Universal-120V’ Or FamilyType = ‘GuideLed PL\/BL NEN’<\/p>\n

    Now I can create a building scene layer package that is specific to the needs of the inspection team.<\/p>\n"},{"acf_fc_layout":"youtube","start_time":"0","end_time":"","youtube_video_url":"
