Gets all CalculatedProperties for a Group.

Calculation Types

Calculation types that start with BoundingBox use element aligned bounding boxes. They can be used for approximations of geometric element dimensions when there are no available properties that would have exact dimensions. Some errors may occur due to bounding boxes not being a perfect fit for the surrounded element.

List of all available calculation types:

Length - calculation of a linear element length or a perimeter of a geometric element that does not have a volume. For elements that have a volume use BoundingBox calculations to approximate the length.
Area - calculation of a geometric element's surface area.
Volume - calculation of a geometric element's volume.
BoundingBoxLongestEdgeLength - calculation that gives the longest edge length of an element aligned bounding box.
BoundingBoxIntermediateEdgeLength - calculation that gives the edge length that is not the longest nor the shortest of an element aligned bounding box.
BoundingBoxShortestEdgeLength - calculation that gives the shortest edge length of an element aligned bounding box.
BoundingBoxDiagonalLength - calculation that gives the distance between 2 opposite corners of the element aligned bounding box.
BoundingBoxLongestFaceDiagonalLength - calculation that gives the longest distance between 2 opposite corners of a face on the element aligned bounding box.
BoundingBoxIntermediateFaceDiagonalLength - calculation that gives the distance between 2 opposite corners of a face on the element aligned bounding box that is not the longest nor the shortest.
BoundingBoxShortestFaceDiagonalLength - calculation that gives the shortest distance between 2 opposite corners of a face on the element aligned bounding box.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

Authorization

User must have imodels_read permission(s) assigned at the Project level. iModel specific permissions may also be applied at the iModel level if iModel level permissions are enabled.

Alternatively the user should be an Organization Administrator for the Organization that owns a given Project or iModel.

An Organization Administrator must have at least one of the following roles assigned in User Management: Account Administrator, Co-Administrator, or CONNECT Services Administrator. For more information about User Management please visit our Bentley Communities Licensing, Cloud, and Web Services wiki page.

Rate limits

All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.
