Release History V23-1 Build 11000

General points

  • As of now, the hatch “HLZ 8 Duo Holz” is available under “SEMA hatch styles”.

Rafter System

  • The new SEMA version makes it possible to subsequently assign timbers, fasteners, 3D objects and steel components to another system, such as a floor, wall, C-plane, roof panel, floor panel or another storey.
    It is important that all components can only be transferred to systems if they can also be created manually in this system.
    One application, for example, would be a quick subsequent allocation of timbers constructed in the joist systems to an adjacent wall, since these components also have to be mounted and packaged in the wall.
    Similarly, free 3CAD timbers or steel beams that come from an IFC structural model can be assigned to a floor, for example, in order to display the SM numbers and dimensions for assembly plans.
    Steel connectors can be allocated from one storey to another directly in the 3D mode, since they should be exported with this storey.
    After marking the component, the new option “Re-allocate allocation” with the two instances “Select target component” and “Select target storey” is now available under the “Others” edit command.
    In order to assign timbers to a roof or floor panel as before, either the new options switch “Allocate components to a roof and floor panel” or “Transfer components to an alternative target system” can be used.
    A message appears to indicate if components cannot be allocated or edits have to be checked.
  • The extensions made to the “multiple cut” command of timber components make it possible, for example, to cut elements faster and without additional processing on several reference areas in a purlin ring.
  • Dovetail joints with additional 3CAD processing have been optimised.

Coverings Floor Wall

  • The behaviour of battens with large layer projections has been optimised. (Company IKB, Bischkopf und Hörmann)

Wall and floor members

  • The complete view of the panel can now be rotated in the display settings (F7) under walls, roof and floor panels, each under “Layers” and the “View” tab. A staggered view is no longer required for this setting. All components of the panel are rotated by means of the “Complete panel” option. The horizontal or vertical section is also rotated with the second function “Complete with sectional view”. Both the X and Y axes can be selected when rotating the view. The sections of the wall are also adjusted accordingly. In order to recognise these rotated walls, they receive appropriate symbols in the view. Thanks to these new options, plans for these panels can be designed even more individually.

Sheet Metal

  • The master data for “Space surface area profile” have been enhanced. It is now possible to assign several middle components in the master data. Consequently, it is possible to create surface area profiles in patterns. Users can allocate up to eight middle components. An individual maximum length can be set for each middle component allocated. When the last middle component has been created, the first middle component is created again automatically. This continues until the user terminates the creating or the end of the spacing segment is reached.
  • Area-covering sheet metal parts now respond automatically to openings. When area-covering sheet metal parts partially hit an opening, the area-covering sheet metal part will be automatically punched. If the area-covering element is interrupted by an opening, the profile is automatically cut off at the opening and the remaining length of the profile is created behind the opening. There is a setting for this in the master data for “Cover area”, “Cover partial area” and “Space surface area profile”. The setting “Openings” can be found under Covering Settings. Users will find the options “cover” and “observe” there. Regarding the option “cover”, it works as before – the openings are simply covered. If you set the option to “observe”, the area-covering elements will identify the openings and react to them. When creating a single surface area profile, there is a switch at the bottom right to select between “observe” and “cover”.
  • As of now, there is a total gross length for the material list available. The value “SBruttoL” can be added by editing the mask.
  • A new edge dimension has been added for the area-covering sheet metal elements. The value is switched on in the F7 settings via “Edge length via cut-to size profile”. This value indicates the seam edge lengths in the 2D view.


  • Only timbers from the rafter and joist system could be transferred to an element previously. From now on, this also works with all timber components that have been created in layers. For this purpose, the component transfer has been enhanced in the third tab of the roof and floor panels. Users can now determine for each layer whether or not timber components should be adopted under the >> more….>> option. Needless to say, the timber components are correctly taken into account and exported during machine exports.

Stair Design

  • A tail with a negative dimension can now be defined in the string at the outlet even in the master data.
  • Balustrades can now also be related to axes of cut strings. Balustrades could only relate to string axes previously.
  • The connecting central axes are now always displayed in board components, for example, for dowel drillings in strings.
  • Short board components, such as strings or handrails in a stairwell, are now no longer drawn in the rising profile, but are displayed in a horizontal position on the developed view. As a result, the overall outlines of the aggregate components become smaller, so that there is less waste per board or paper during the production of components.

3D Objects

  • A new option button is now available in option 1 and option 2 with an extension made in the “Position” or “Copy” command of 3CAD objects. This button can be used, for example, to move fasteners easily in one plane in the ground plan without changing the Z position of the component. The button is available in all 2D planes (wall views, sections, C planes, ground plan). The button is activated by default.

Single Member

  • As of BTLx Version 2.2.0, it is possible to export a shadow contour as a silhouette in the outline. This shadow contour is required, for example, for the nesting of several individual boards in a large-format board. This new option can be set in the machine export settings under the exterior contour.
  • The standard machine settings for the export to production machines from the SCM company (Oikos/Area) have been revised.
  • The BTLx export of slot machining with a distance to the reference area has been enhanced.
  • The conversion of the machining “Front scarf joint” to “Slot” has been made possible in the Single Member feature. In addition, the BTLx export of these machinings has been improved.
