Updates in tools for automated precast fabrication

Export Unitechnik (79), Export EliPlan file, BVBS Export and HMS Export contain several improvements.

Export Unitechnik (79)

Export Unitechnik (79) has been improved in the following ways:

  • The cutpart former embedbuilding object that represents an object that is to be cast into a concrete structure and that is used to connect structures or as an aid when constructing a structure

    For example, a cast-in socket is an embed that is placed in concrete structures to allow parts to be fastened together on site. In Tekla Structures, embeds are typically steel parts and they are added to cast units as sub-assemblies.

    polygon is now exported fitted to be within the contour polygon.

  • The visualization in Tekla Structures model for the scanned geometry of the embeds is now drawn in the respective double wallplate that represents a structure such as a wall or roof panel

    In Tekla Structures, a panel is created by picking two or more points.

    In cast-in-place concrete the term wall refers to a concept similar to panel.

    shell.

  • STEELMAT insertion point, length and width were previously incorrectly exported for some meshes. This has now been fixed.

  • Main tab:

    • You can now specify Output file structure as Single layer, 1 slabdate, n steelmats. This new option only exports the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

      (1) Main part can be an assembly main part or a cast unit main part.

      (2) input part that the user selects first when creating a component

      (2) Connections and details always have a component main part.

      of the cast unit as SLABDATE, and meshes and embeds from whole cast unit in one row in export X axis direction with a 1 mm gapany space between two objects

      The term gap is used in its general sense in Tekla Structures.

      between them.

  • SLABDATE block data specification tab:

    • The braced girder diagonal wire rebar handles at arcing points affected the double wall total and production thicknesses when bent rebars were excluded. This has been fixed.

      Also a new option Double wall width has been added for the settings Total thickness and Production thickness. This option exports the template report property CAST_UNIT.WIDTH.

  • Embeds tab:

    • Special assembly symbol definition file now supports template property values or embed part names. Embed template property values or embed names have to be enclosed in quotation marks. Embed template property values or embed names have to be enclosed in quotation marks.

    • Previously, when the corner symbol option was selected for the Export assemblies setting, and a special export assembly file was used, there were problems in the export. This has now been fixed.
    • Previously, when a double wall shell was created from more than one part and the Cut outer assemblies setting was switched on, the embeds in the secondary part(1) part that exists in a building object and that is connected to the main part

      (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

      (2) input part that the user selects after selecting the component main part when creating a component

      (2) A component can have none, one or more component secondary parts.

      were missing from the export with certain Export Groups settings. This has now been fixed.
    • Electric tubes are now not excluded for the whole length when you use the Cut outer assemblies option together with non-turned double walls

  • Reinforcement tab:

    • A new option All without hooks has been added to Rebars export > Straight to export straight rebars without hooks only. The All option has been renamed to All including hooked.

      Note that the hooked bars are controlled by the Straight setting, not by the Bent setting.

    • Braced girder classes or names: You can now export braced girders within the STEELMAT block using the new option Within the STEELMAT block. By default, the braced girders are exported outside of the STEELMAT block.

    • Initially, when you exported braced girders within the STEELMAT block without any meshreinforcement that represents a mesh of steel bars in two perpendicular directions

      In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

      , the braced girders were excluded. Also the braced girders with lower concrete cover didn't affect the father STEELMAT-block coordinates. These issues have now been accounted for in the final functionality.

    • The Spacer type option Automatic has been renamed to Automatic, rebar type 1, and its behavior has been changed so that when the element is thinner that 100 mm, the spacer type is always exported. A new Spacer type option Automatic, all rebar types has been added to export spacer types for all rebar types.

    • Braced girders modeled with only two chords are now correctly recognized and exported.

    • It is now possible to export braced girders Z coordinate as 0 using the new option Without concrete cover.

    • When the BRGIRDER block is exported within the STEELMAT block, the STEELMAT insertion coordinates are now correctly adjusted in case the girder minimum coordinate points are outside the mesh.

  • TS configuration tab:

    • You sican now set Export CONTOUR to Simplified, which exports a simplified contour using 4 x, y corner points of the element.

    • The Extend contour and add formwork setting has been improved. Now formwork is not added if there already is an embed with the same geometry. Also, the contour is not extended for electric tube embeds.

    • Previously, line attributes were not exported for second shell of the double wall when Double wall turned was set to No, shell-specific coordinate systems. This has now been fixed.

    • The Double wall turned setting has been improved. The No option has been renamed to option No, one coordinate system and a new option No, shell-specific coordinate systems has been added to export the second shell in the Z direction from the bottom of the pallet upwards.

Export EliPlan file (68)

Export EliPlan file has been improved in the following ways:

  • All geometrical data with the Plotter and Pieces blocks are now exported rounded to the closest millimeter in metric environments.

  • Previously, full depth cuts placed at hollow core profile chamfer lines with certain profiles were exported with incorrect geometry. This has now been fixed.

  • Rectangular openings at the edge of hollow core slabs with certain profiles were occasionally exported as a thin line, instead of a box shape.This has now been fixed.

  • A new tab Data settings was added, and some settings were moved to the new tab from the Data content tab.

  • Hollow core slabplate that represents a concrete structure

    In Tekla Structures, a slab is created by picking three or more points.

    Slab may be part of a floor, for example.

    thickness is now read from the profile instead of the geometrical thickness (in case the complete top or bottom face is cut).

  • Plotter data for cuts and recesses exported as lines will have the thickness/depth value in case the cut is of even depth.

  • Recesses that cut the complete area of the element are now plotted.

  • Parameters tab:

    • EliPlan export now supports export version 3.0 (FloorMES). You can find the new version in the Export version number list. The 3.0 (FloorMES) version file format is intended for interfacing with newer Elematic FloorMES versions, and is based on GUID. The file format has been extended with additional data fields, and therefore it is not backwards compatible.

    • Version 3.0 of the export supports the export of accessory code to plotter data.

    • Export version 3.0 supports the export of accessory code for openings.

    • The Filter by part setting has a new option Selection filter which uses a selection filterfilter used for defining which object types can be selected

      Selection filter chooses model objects or objects in drawings according to object properties.

      Selection filters can be standard or user-defined.

      For example, selection filters can be used to select parts for drawings or analysis.

      for filtering element data, materials or secondary concrete elements.

  • Plotter data tab:

      • New setting Export of weep holes: Version 3.0 of the export supports the export of weep holes.
      • You can now specify plotting of additional reinforcement as bounding boxrectangular border with the smallest measure within which all the selected points that position the model objects lie

        In Tekla Structures two-dimensional bounding boxes are used in drawings and three-dimensional bounding boxes in models.

        or as lines using the setting Plot additional reinforcement or Plot cutout/embed as lines.
  • Data content tab:

    • The new EliPlan export version 3.0 supports the export of stack results. You can select if the UDAobject property created by the user in order to widen the range of predefined object properties

      User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

      is read from the main part or from the cast unit.

    • You can now specify the accessory code for standard embeds such as steel parts. This will be the code written to each embed in the #Plotter (if applicable) and #Materials blocks, and the chosen option should be used as a base for further data conversion mapping. The default option is NAME|PROFILE-LENGTH|MATERIALGRADE.
  • Data settings tab:

    • It is now possible to specify a UDA to read the strandreinforcement that represents a group of wires spun together

      code. Default reads the value from the UDA TS_STRAND_CODE. It is also possible to export strand code from a template attributeattribute in a template object that Tekla Structures uses to calculate and display information from a model database

      Template attributes represent object properties.

      , including custom properties.

    • The Tag for lifters setting has been improved and now also rebars can be specified as lifters using a classpart property that groups parts according to identifiers given by the user

      The identifiers of classes are usually numbers. Classes can be used for defining the color of parts in the model, for example. Class does not influence the numbering of model objects.

      or a name. Now Tag for lifters also has an option to specify how the lifters geometry should be plotted - as outline or as center point.

    • It is now possible to specify multiple classes or names for the Tag for lifters setting. If the name consists of multiple words then it has to be enclosed in quotation marks.

HMS Export

HMS Export has been improved in the following ways:

  • The height of braced girders is now calculated more accurately. The height is now measured as the distance between the top and bottom rod center line points.

  • Rebar strands are now exported from strand objects only.

  • Reinforcement tab:

    • New functionality was added on the Reinforcement tab to include slab cross bar reinforcement in the export. For the new settings Custom top strands and Custom bottom strands, enter the quantity, diameter, distance and pull force. For the new settings Additional strands and Reinforcement, enter the name, class, UDA or template attribute.

      The custom strand settings are meant to be used if no strands are modeled. If there are modeled strands, the custom strands will be included in addition. Additional strands can be used to designate any other specific rebar object to be exported as strand, as only strand objects are included in the export by default. Reinforcement can be included in the export as cross bars by specifying them in the Reinforcement setting.

BVBS Export

BVBS Export has been improved in the following ways:

  • Circular rebar sets are now exported in the same way as circular rebar groups.

  • New Settings tab:

    • The groups Drawing data and Reinforcement position were moved from the Parameters tab to the new Settings tab.

    • There is a new setting Project number with the following options:

      • Project properties: The export fetches the project number information from the project properties set in Tekla Structures.

      • Project properties UDA: The export uses the UDA name entered in the User-defined project number box.

      • Fixed text: The export uses the text entered in theUser-defined project number.

  • Advanced tab:

    • A new setting Bent leg arc radius was added with options Inner edge and Center line.

      This new setting defines which bending radius is used to calculate the arc length: Bending radius to the rebar center line, which is the default for most interfaces, or to the rebar inner edge, in which case the bending radius is shortened with half of the rebar nominal diameter.

      BVBS export uses arc geometry in two cases:

      • For circular rebars such as spirals or hoops.

      • When bent rebar has more than 1 bending radius, the bends with the larger radius are exported as arc sections.
