SPACE GASS API
REST API for SPACE GASS — structural analysis and design software.
Usage
Each running instance controls a single SPACE GASS session and works on ONE open job at a time.
Authentication & Licensing
Auth is enforced server-side by the licensing module; no per-request credential is required. Licensing failures surface as a 403 with one of the following errorCode values:
REGISTRATION_REQUIREDREGISTRATION_UNSUPPORTEDLICENSE_LOSTCORE_LICENSE_UNAVAILABLEMODULE_LICENSE_UNAVAILABLE
To allow license-free access to unrestricted GET endpoints, set the access mode to ReadOnly (before opening a job).
Client SDKs
To get started quickly, use our official client SDKs:
- .NET Client: Available on NuGet (
dotnet add package SpaceGassApi) · Source · Examples - Python Client: Available on PyPI (
pip install space-gass-api) · Source · Examples
SDKs are generated with Kiota and follow its fluent request-builder convention, so client calls mirror the URL path of each endpoint.

Filters
Named filters — composite criteria across nodes, members, plates, sections, axis ranges, etc.
Moving Loads
Moving-load module — collection-level settings and the selected members/plates that moving loads are applied to
Moving Load Scenarios
Moving-load scenarios — the vehicle/pressure loads along travel paths (with their loads and combinations) that generation runs over
