Project

A Project is basically a building project which can be created or imported into the bim+ platform using the appropriate bim+ services.

Team

A Team is a tenant/company which work on the projects. The team has to be specified and setup through the bimplus portal as so called slugs to present a clean URL . The team slug will be used to know which tenant database to work on. Please see user administration service for more information.

Object

Objects are the primary component of the project tree and it exists in two forms.

  • Node: Objects with no graphical representation
  • Geometry: Objects with graphical representation (See Geometry)

Please see the detailed structure of the issue in the Object Model

Topology

Topology is a hierarchical tree representing all its child nodes. A topology tree consist of components which can have a graphical representation(objects or elements) or components which does not have a graphical representation(nodes). A topology tree can be obtained both on the project as well as on the object level.

  • Please use the bim+ Project Service for obtaining/filtering the project topology tree. This will yield the topology nodes filtered till the sub-project level.
  • Please use the bim+ Object Service for obtaining/filtering the object topology tree. This will yield the topology nodes with all the properties, attributes, geometry and children.

Geometry

It represents the geometrical information(graphical representation) of a building. Please see the detailed structure of the issue in the Object Model

There are three type of Geometry objects.

  • mesh: It is the default geometry type. It is an uncompressed mesh format where the geometry object will be compressed on the server before storing it into the database.
    Example
    mesh: {
      colors: 4291993670,
      vertices: \[ 96.149, 179.546, ... \],
      faces: \[ 4,0,1,2,3, 3,4,5,6, ... \]
      }
where,
color:  array of decimal RGBA values;
vertices: plain array of 3D vertices coordinates like [x0, y0, z0, x1, y1, z1, ...]
faces: plain array of faces definitions like first number is quantity of vertices, than vertex indices list, see example.
  • meshblob: It is a compressed mesh format intended to be used in the desktop CAD applications. Internal CAD format of the geometry will be converted into a bim+ compressed mesh format with the help of a DLL in order to minimize the JSON object.
    Example
    meshblob: "d273f7a6a7d8f8725484fe6282..."
  • threejs: It is a format which is optimized for viewing on mobile devices or in browsers where the native model is filtered and tessellated in order to deliver minimal JSON size and maximal navigation speed (FPS). This model has ThreeJS JSON v 3.1 format and can be directly parsed by the client.
    Example
    threejs: {
         <ThreeJS_JSON_format>
         }
  • Please use the bim+ Object Service for seeing and filtering different geometry type information.

Objects with geometry types "mesh" or "meshblob" can be written into the bim+ database, whereas the "threejs" geometry type is optimized for viewing on mobile devices or in browsers and cannot be written into the database directly.

ElementType

Element type describes the type of predefined building elements required to build a building (eg: wall, window, door etc) Each element type have an unique id. Please see the detailed structure of the ElementType in the Object Model

The available element types can be found under 2.1.4.1 bim+ Element Types

Issue

Issues are problems or remarks which can be assigned to any project. Comments or attachments can be added to the issue. Please see the detailed structure of the issue in the Object Model

  • Please use the bim+ Project Service for creating/deleting an issue or for getting all the issues assigned to a project
  • Please use the bim+ Issue Service for doing all the specific issue related actions

Pin

Pins are relation between an issue and an object. It defines position of an issue in the 3D space. Please see the detailed structure of the pin in the Object Model

  • Please use the bim+ Issue Service for creating/deleting a pin or for getting all the pins assigned to an issue
  • Please use the bim+ Pin Service for doing all the specific pin related actions

Attachments

Attachments are mostly documents or any media files with additional information which can be assigned to any project, object or issue. Please see the detailed structure of the attachment in the Object Model

  • Please use the bim+ Project Service for creating/deleting an attachment or for getting all the attachments of a project
  • Please use the bim+ Object Service for creating/deleting an attachment or for getting all the attachments of an object
  • Please use the bim+ Issue Service for creating/deleting an attachment or for getting all the attachments of an issue
  • Please use the bim+ Attachment Service for doing all the specific attachment related actions

Division

A division is a part(department/client) of a team which works on the project.

Discipline

A group of element types constitute a discipline. They are predefined. Please see the detailed structure of the attachment in the Object Model.

An ElementType cannot belong to two disciplines.
