bimsync APIs

bimsync has a range of APIs that makes it easy to embed and access BIM data in your software. We provide APIs for 2D and 3D visualization, issue handling using the standard BCF API and access to all BIM data through our intuitive REST API. 

 Viewer 3D API

Visualize large BIM models in any WebGL compatible browser. No plugins or installation required.

View multiple models

Configure the viewer to load multiple models and turn these on and off individually. 

Create clipping planes

Create up to six simultaneous clipping planes in the model. You can also do quick sectioning on any side of an object.

Correct visualizations

See colors and translucency exactly as it was added from the individual authoring tools.

Customize appearence

Control object visibility or make objects translucent. Customize appearance by giving objects a different color.

Integrate 3D map data

You can stream map data from external sources. Currently we support data from the Norwegian mapping authorities but the list can be extended on request.

Other features

  • Look at function 
  • Walk mode with gravity to walk up down stairs
  • Select multiple objects
  • Set walk speed, field of view and rotation speed
  • Touch enabled for tablets, smartboards and phones
  • Take screenshots
  • Place images and sprites in the model

 Viewer 2D API

Auto-generated floor plans for all models as SVG files with relevant BIM information included

Interactive floor plans

bimsync generates floor plans for every floor in you building including symbols for doors.

Select, highlight and colorize

All closed polygons like spaces can be given a background color while all polygons can be given a ticker line and color to indicate selection.

Add your own symbols and graphics

Add symbols and signs to the canvas to indicate technical components or escape routes as on the example. Provide your own images.

Select and highlight spaces and objects

Select one or more spaces by clicking on the canvas or highlight objects on the canvas in the same way as highlighting objects in the 3D view.

Set and track the position

The built in position marker can be used both to sync position on a given floor and room with the 3D viewer or to navigate the model. Drag the arrow around to navigate. There is a separate API library to sync the 2D and 3D viewer with a few lines of code.

Other features

  • Attach events to objects
  • Touch support for tablets, Smartboards and phones
  • Create 2D snapshots / viewpoints


Our REST API gives you access to the information in your BIM files as well as members, teams and linked data.

Projects, organizations, teams and users

bimsync has a flexible model for handling projects, organizations, teams and users. Users can belong to multiple projects, teams and organizations and be managed through the API.

Models and revisions

Create, update and delete models. A model is a repository to track versions of BIM files. bimsync gives you access to the complete revision history for any given model.

IFC data for objects and types

Get access the I in your BIM. All information about the individual BIM objects, corresponding types and property values and units is available. Use queries to get the information you need, presented in a harmonized format.

Model structures

Retrieve any of the existing structure in your BIM models. Structures are available using the composition relationship , component types, layers and groups ( generic grouping and zones ) 

Other features

  • OAuth 2.0 authentication
  • Create tokens for 2D and 3D viewer
  • Work with libraries. Libraries are any external information linked to objects in the BIM. It can be product information, documents and drawings, classifications, ontologies like bSDD or your own imported structure from a spreadsheet or comma separated file.
  • API v2 extends API v1 with a range of new features and is currently in Beta.


bimsync supports the BCF API specification from buildingSMART international with additional support for import and export of files on BCF 1 and 2 format.

Exchange issues from a whole range of BCF compatible tools using our built in BCF server. bimsync supports every available BCF version for file based exchange as well as the various versions of the BCF API.

Viewer Widget API

To make it easier to combine the various APIs we have created a viewer widget API that will add touch support and sync 2D and 3D with a few lines of code.

The viewer widget API is a addon API to add quick support for:
  • Context menus
  • Keyboard shortcuts
  • Joystick navigation
  • Mobile/tablet/smartboard/phone navigation
  • Easy interaction with spaces
  • Sync 2D with 3D
