The "Generate analytical surfaces based on a space of the physical model" option has been added to the "Elements" group in the Open BIM Analytical Model toolbar. This feature allows users to obtain the surfaces outlining a space from the physical model and creates the equivalent analytical surfaces. The space will also be added to the analytical model and all generated surfaces will be assigned to that space.
When entering an analytical surface in previous versions of Open BIM Analytical Model, all of its points needed to be coplanar. Now, the first three points inserted into the work area determine the surface plane, while the rest are projected onto said plane. This makes it much easier to enter new surfaces by means of the template snap from the physical model.
A new project review process has been implemented to detect possible inconsistencies in the analytical model and, thus, make it easier for the user to solve them. To do so, the following options have been added to the "Errors" group in the application toolbar:
Due to the new management of visibility and object snaps of external elements system, the "Snap options" panel in Open BIM Analytical Model has been modified in order to remove the components of the physical model and thus avoid duplication. The "Template" tab now has only two elements: "Spaces" and "Openings".
Additionally, the "Show/Hide template" option in the toolbar has been removed as this action can now be performed from the "Elements read" panel in the left sidebar of the application.
As of version 2023.a, "Open BIM Analytical Model" displays a panel with a summary of the elements added to the project after completing the automatic generation process of the analytical model. The added components can be consulted from the "BIM Model" option in the program's toolbar.
As of version 2022.g, Open BIM Analytical Model can also be installed in Chinese.
As of version 2022.f, Open BIM Analytical Model allows edges originating from overhangs in the physical model, such as defences, to be introduced. To do this, the "Overhang" option has been added to the "Edge" configuration panel, in the "Adjacency" group.
The algorithm for automatically generating the analytical model has been improved in the following ways:
As of version 2022.c, the Open BIM Analytical Model "template editor" allows users to specify that an external wall from the architectural model is a party wall.
By doing so, the surfaces derived from said external wall will be assigned to the boundary "party wall" when using the automatic generation process of the analytical model.
Party walls have also been added to the "Template" group of "Snap options" in order to control their visibility and the object snaps in the application’s work area.
As of version 2022.b, Open BIM Analytical Model can read the buildings entered into the site model that has been defined for the project linked to the BIMserver.center platform. Project location information can be entered via the free Open BIM Site application, available from the BIMserver.center Store.
To read the buildings from the Open BIM Analytical Model environment, the corresponding collaboration must be marked during the linking or updating process of the BIMserver.center project. Once in the application, the buildings will be interpreted as the physical model’s "Own shadows". These elements can be used as a reference to design the analytical model manually or to automatically generate the analytical model. In the latter case, when using the "Analytical model" option in the "Generate" group in the toolbar, shadow surfaces will be created for the analytical model based on the shading elements of the physical model.
The BIM thermal simulation applications developed by CYPE can use the analytical model from Open BIM Analytical Model and, thus, consider the shading elements generated based on the buildings.
As of version 2022.b, applications with 3D drawing surroundings allow a viewing volume to be defined from the geometric envelope of the scene content. The arrows allow the viewing volume to be adjusted by moving their faces and the arches allow the viewing volume to be adjusted by means of 6 clips planes.
As of version 2022.a, Open BIM Analytical Model includes the IFC Builder tool which allows users to design a simple architectural model, suitable for generating the analytical model, in the same Open BIM Analytical Model project. To launch the tool, users must press the "Architectural modelling" button available in the "Project" group in the application’s toolbar.
Once the architectural model is finished, it can be sent back to Open BIM Analytical Model using the "Export" option available in the "Analytical model" group in the IFC Builder toolbar. As the model already contains analytical geometry, when generating the analytical model in Open BIM Analytical Model the "Use the outlines of the spaces defined in the IFC model" option in the configuration panel must be checked.
