SAPFIR-Structures
- Updatable soil model may be attached to 3D model of the structure. In SAPFIR program it is possible to make mutual arrangement between building model and the soil. Soil model with the snap is automatically transferred to VISOR-SAPR module. The user could temporarily hide certain soil layers, make imaginary 'elevation view' of soil owing to section box extents. Soil model may be updated with account of modifications made in the SOIL system; the specified snap remains the same.

- The user could manage the design parameters of steel structures directly in SAPFIR environment. It is possible to define classes for steel, additional design parameters for columns and beams, selection limitations for sections. With parametric filter, the user could select elements of steel structures by certain parameters. When data is transferred to VISOR-SAPR module, the program automatically generates structural elements and false deflection fixities.
Define design parameters of steel structures in SAPFIR environment
- New tool to define intermediate levels in storeys. It is possible to define the snap for objects (walls, slabs, columns, beams, roofs and rooms) to levels (top of storey, bottom of storey, intermediate). Levels may be displayed at section elevations. When you edit certain level, the program automatically modifies levels of objects that refer to this level.
Define levels
- New commands to define a snap of vertical objects (columns, walls) to the floor slab. When the level of floor slab is modified, the height of vertical objects is modified respectively.
Snap of walls and columns to the slab
- New object 'Inclined slab' is introduced.
- Offsets are available for beams and columns. Offsets may be generated to the level of storey top, storey bottom, intermediate levels. Moreover, it is possible to generate offsets to selected object: for beams – to slabs and conventional planes (hatching), for columns – to walls.
Offsets to slab are generated
- Input data may be defined for wind analysis with pulsation.
- Option to define snaps of loads to selected object. The load is referred to the level where the object is located. When the object level is modified, the load is automatically moved as well.
- New mode for selection of points (vertices) of objects to move them together: check points and axial lines are displayed for several selected objects rather than for one.
- New mode for selection of line segments to move them together or to assign boundary conditions.
- New tool that enables the user to check the integrity of design model visually. On design model you will see contour plots of distances to supports and indication for elements with no support.

Check for model integrity
- During generation of design model the user could automatically assign restraints to vertical elements (columns, walls) if there is no foundation slab.
- Local libraries of materials are supported in projects.
- New option to renumber storeys.
- In object properties there is one more parameter – Storey in order to display the current storey of an object or to move the object from one storey to another.
- New mode for presentation of project structure with tags of structural elements (instead of names).
- The user could assign visibility of objects on every view regardless of other views, it is very helpful for documentation views and drawings.
- It is possible to select the group of drawings, for example, to delete them.
- Correct work of the program is provided with buildings that have different snap.
- Enhanced algorithms applied when the slab contour is modified: cleanup of support elements, generation of punching shear contours, etc.
- New tool 'Manage cleanups' indicates which objects (slabs, walls, beams) crop the selected object. It is also possible to cancel these cleanups.
New tool 'Manage cleanups'
- When the floor slab is transformed into foundation slab, the openings remain the same.
- Joints (vertical) may be saved to SAPFIR library.
- Joints in large panel buildings may be modified when the model is updated or checked.
- Enhanced algorithm to select joints.
- For the Line in the shape of polygon, there is a new parameter – number of vertices.
- Option to cut off with view cube when images are exported to *.jpg, *.png.
- In parameters of SAPFIR objects the user could select layer in the drop-down list of Layers.
- In floor plans it is possible to generate openings in foundation slabs and floor slabs separately.
- New option to edit facets and fillets for contours: to replace the facet with the fillet, to modify radius of fillet, to delete facet or fillet.
Design of RC structures
- Types of pilot reinforcement (PR) are automatically generated and then assigned to elements of design model according to design procedures for slabs, walls, columns, beams in Design of RC structures module. In this module there is a system of user-defined settings that enables the user to define and assign the types of pilot reinforcement (PR). These settings are applied by default.

- New option to generate and manage the asymmetric reinforcement in stiffness diaphragm.
- Set of options to define zones of reinforcement in slabs: general reinforcement pattern, working length of rebars with account of anchorage, define zones by diagonal, define zones from centre.
- Option to define different parameters for transverse reinforcement in beam.
SAPFIR-Generator
- When *.spf file is opened, if the model contains import nodes DXF, then the program checks whether *.dxf files are available at the specified paths. In case such files are not found, the program displays message that *.dxf files are not found and import nodes are frozen. The warning that there is no related *.dxf files is not provided any more.
- New node is introduced: 'Enhanced generation of storeys by specified levels'.
Node 'Enhanced generation of storeys by specified levels'
- The Section and Material nodes are introduced.
Section and Material nodes included as external parameters
- The user could search for node by its name.
Search for node by its name
- New option to show/hide the ribbon in GENERATOR in order to increase the graphic area.
- New options to edit several objects: bake, freeze, unfreeze, hide/show all nodes in the model.
- Commands to update the model (auto and manually) to speed up the Generator system.
- The work in the 'Generator' dialog box is enhanced and optimized.
- Nodes may be presented in colour (data defined/data not defined). Inputs of node may be also displayed in colour: red – required to be filled, orange – one of inputs (depending on type of data) required to be filled, grey – data was already defined inside node, white – no defined data inside node.
- Enhanced node for cutting openings in slabs. It results in less time necessary for work and considerable reduction of file size if this node is used inefficiently.
Plugin for Grasshopper
- For our standard nodes (wall, slab, column, beam, pile, prism, surface, points, lines) it is possible to activate the 'Properties of SAPFIR object' dialog box within the Grasshopper environment.
'Parameters SAPFIR' dialog box activated in Grasshopper
- Input “Param” is added at nodes: “wall”, “slab”, ”column” ,”beam”, “pile”, “prism”, “surface”, “points”, “lines”.
- New nodes are added: “Material” and “Section”. When RC node is selected, the program automatically displays the node inputs where the user could define parameters for the section (dimensions b1, h1, b, h) or select appropriate materia
- Generation of surfaces from Grasshopper is speeded up.
- Surfaces may be generated by massive of closed 2D contours (lines).
Data Import
- New tool that enables the user to automatically replace materials when the model is imported from IFC. It is possible to save corresponding settings and apply them many times in the current and other projects.

- Import of elements from analytical model IFC.
Thermal Analysis
Transient heat transfer problem analysed in LIRA-FEM (video)
- New option to simulate steady-state and transient heat transfer problems. New model type (15) is introduced for this purpose. In this case, nodes of design model will have only one degree of freedom – temperature t.
New model type
- New types of finite elements are introduced: one-dimensional, plane and 3D FE for heat transfer analysis. New special finite elements for convective heat transfer are provided to simulate the contact between the surface and environment.
- New types of loads are introduced: predefined temperature at node, heat flow on the body surface, predefined exterior temperature for convection elements, and three types of transient loads.
