LUSAS-authored plugins for third-party software

LUSAS Grasshopper plugin

• Free to use, the LUSAS official Grasshopper plugin is available from the food4rhino website, as well as from a link within Rhino 8's package manager. It is for use with Rhino 8 (for Windows)
• This initial release lets you create structural models for LUSAS using dedicated Grasshopper components that enable the definition of attributes such as materials, sections, loads, supports, and more. 
• Interact directly with Grasshopper parametric models, make parametric changes and preview the model in real-time within Rhino.

Linking with LUSAS

• Seamlessly link to LUSAS with the press of a button.
• If LUSAS is not installed, a file can be created by the plugin and passed to a LUSAS user who does.

Revit 'Export to LUSAS' plugin

• Available from the Autodesk App Store, the LUSAS-authored 'Export to LUSAS' plugin allows for a Revit analytical model to be exported to LUSAS for finite element analysis and optionally design checks to international codes of practice.
• Autodesk Revit "analytical elements" are converted to appropriate LUSAS features and finite elements, along with cross-sections, material attributes, loads and supports. Any export issues are reported in a friendly dialog, making them easily spotted and fixed.
• The new plugin is free to download and install to your Revit "Add-ins" ribbon.

Exporting to LUSAS

• Models exported using the plugins may be opened by any LUSAS user with a valid bridge or civil licence.
• LUSAS version 21.1 will import files without any need to update your licence. LUSAS version 21.0 will need a licence key update. Earlier versions of LUSAS do not support Revit import.
• If the exporter doesn't have LUSAS installed or an appropriate licence available, a file can be created by the plugin and passed to a LUSAS user who does.

Tekla 'Export to LUSAS' plugin

• Available from the Tekla Warehouse, the LUSAS-authored 'Export to LUSAS' plugin allows allows for a Tekla Structures analysis model to be seamlessly exported to LUSAS version 21.1 for finite element analysis and optionally design checks to international codes of practice.
• The model export process covers most of Tekla's analysis model features, such as: analysis bars, panels, rigid links, loads supports, materials and profiles. Any export issues are reported in a friendly dialog, making them easily spotted and fixed.
• The new plugin is free to download and install into your Tekla application

Exporting to LUSAS

• Models exported using the plugins may be opened by any LUSAS user with a valid bridge or civil licence.
• LUSAS version 21.1 will import files without any need to update your licence. Earlier versions of LUSAS do not support Tekla import.
• If the exporter doesn't have LUSAS installed or an appropriate licence available, a file can be created by the plugin and passed to a LUSAS user who does.

Non-LUSAS authored plugins for third-party software

ALLPLAN

• Users of Allplan Bridge 2023 can synchronize analytical models over the Allplan Cloud (via Bimplus) with LUSAS finite element analysis software. The initial release of this connection supports concrete box girder bridges, with or without pre-stressed tendons, with more bridge types to be supported in the future. Via the Allplan Cloud, analytically relevant entities from Allplan Bridge can be transferred to various structural analysis solutions for further processing, providing users with more flexibility to utilize external analysis software of their choosing.
• A verification example enables users to fully demonstrate and verify the calculation methods used in Allplan Bridge for reinforcement design and code-checking. A simply supported single-span pedestrian bridge designed as a prestressed concrete girder with a single solid T-shaped section with haunches is used to help users to fully understand the inputs and the results provided

BIM level 2 compliance

• Bring model data from different disciplines together in a federated model for comparison and clash detection and deliver your projects to the BIM level expected by your client. 
• LUSAS helps you achieve Level 2 compliance by sharing design information through the IFC common file format. Reports can be produced in the compliant PDF format. Information in reports can be standardised through templating to include all required input and output data.
• An IFC model created by LUSAS can hold geometry and attributes in the standard format and other LUSAS-specific information as ‘private’ data. Retaining the complete file structure ensures that all data can be passed to your client for its records.
• LUSAS supports import and export of IFC files (up to IFC4). Export can be to the Structural or Architectural domain, ensuring that your project team can make the best of the shared information.
