Release History V22-2 Build 10600

General points

  • The edit command “Others”, “Sequential numbering” has been activated for CAD texts and all components that have a material list tab. As long as the command is active, all components that have already been numbered are highlighted in colour. This way, users can constantly monitor the components that have already been numbered. All components are deselected again after the command has been completed. The increment of the unit steps can be suppressed by holding down the Ctrl key. Another new feature is numbering with the right mouse button pressed. All components are numbered consecutively according to the marking sequence with this option. Of course, the sequential numbering also works in the 3D view. <Sequential numbering>
  • The min/max limit of the entry is evaluated for all numeric inputs, and a message of the definable range of values is displayed if the limit is exceeded.
  • When a component is marked, the weight and net volume are now automatically displayed in the lower entry line. If several components are marked, the program calculates the weight and volume of all components. The weight of the centre of gravity is used for the calculation of components, such as walls. Consequently, the loading weight can be checked even when marking the walls. The normal weight is displayed for all objects that do not have a centre of gravity.
  • The texture master data has been extended by 3 more references. It is, therefore, now possible to use different textures for all 6 sides of an object. In addition, the texture alignment has been adjusted so that textures with the texts they contain can always be read correctly. This behaviour can be controlled with the option “Direction” for the bottom reference. If this option is deactivated, the behaviour of the textures is the same as before.


  • As of now, a circle can be determined as a circle segment by 2 points and segment height. For this purpose, another input form has been incorporated into the CAD circle.
  • In the case of CAD lines and arrows, the positioning command has been expanded to include the option “Shift marked end (Alt 1)”. With this command active, the marked end can be shifted. This option combines the edit commands “Position” and “Cut/Lengthen”.
  • If a representation with dimensioning objects is saved as an image, these are no longer converted into CAD objects as before. Users are, thus, given a visually better result and they can adjust the dimensions at any time. Height dimensions are fixed when being inserted so that they do not change their value unnoticed. This information is displayed accordingly in the component note.
  • The area and intersection point dimensioning feature now also responds to timbers in left and right layers. In addition, users can determine in the component selection menu of the dimension line for timbers and coverings whether components of layer 0 or all components should be dimensioned. With the third option “Current”, the layer of the dimension line determines which components are dimensioned. If the dimension line is on a layer on the left, only components of this layer are dimensioned. <New features in the CAD area>

Rafter System

  • From Version 22-2 on, the cone of the DT tenon can be defined via the upper width of the DT tenon (fixed or as a percentage of the component). The rabbet and the marking-out are taken into account for the tenon length required for the calculation.
  • The associated single member processing and the focused single member processing are highlighted in colour in the single member list in the 3D representation of the building by the marking of nodes. The assigned line colour from the colour settings for “marked areas” is used for this.
  • The existing end types “Skew notch, on both, sides inclined” and “Skew notch, on both sides, straight” have been enhanced to include a definable distance between “Front” and “Bird’s mouth” in the master data. <New features in joining>
  • The grain direction arrow has been visually adapted and enabled for all timber components in the 3D representation and production drawings for the reference side. The display in which the grain direction arrow is displayed can be set in the “Display settings (F7)” of the component for “View”, “Top view” and/or “3D view”.
    Changes to the grain direction, which are defined in the master data of the component, now also affect the texture in the 3D view and, thus, enable clear working.
    New options are also offered by the “reference side”, which can be defined on the “Nesting tab” for timber components and coverings and is now newly displayed in the production drawing via a reference arrow.
    This arrow can be activated in the “Display settings (F7)” under “Images+3D”, “Auto-cut” and “Component drawing”.
    The “reference side” can now be used to determine which side is on top for the machine export by means of the new setting “Reference side top”. This definition is important, for example, for components on which a high surface quality is used for one side and which should not be damaged by the machine table.
    There are now two new settings available on the “Nesting tab” to determine the respective surface quality for the reference side and the reference opposite side. The standard designations for the surface quality “Irrelevant”, “Industry”, “Industrial visible” and “Residential visible” are available for each side. Users can assign a colour to the different qualities in the “Colour Settings” under “General” for the quick and clear displaying of the different surface qualities in the project. The qualities can then be displayed in the 3D representation by using the setting “Highlight the quality of the reference sides in colour” in the “Display settings (F7)” under “Visualization”.
    The designations for the surface quality can be changed and saved in the “Colour Settings” using a right click on the text. The newly defined designations will be automatically adopted for all settings in the program.
    In the production drawings, users can use the “Display Settings (F7)” under “Images+3D”, “Auto cut” and “Component drawing” to display the designations of the surface quality for the reference sides as text for the reference arrow as well.
    The two new placeholders for the reference side -> “@B-QUALITAET-REFSEITE@” and for the reference opposite side -> “@B-QUALITAET-GEGSEITE@” are also available for the surface quality. <New Features Solid Wood Construction>

Floor Wall

  • The edge dimensions of a floor shape can now be activated in the display settings (F7). This setting can be found under Floor -> Floor shape -> Edge dimensions.
  • Nailing lines can now be automatically connected to one another via the wall automatism if they have the same entry in the formula and are aligned. To enable this, the option “Connect nailing lines from a distance” has been integrated in the presettings (Alt+F7) under the Walls / Outline system in the ‘auto’ tab. The value can be used to determine the distance from which the nailing lines are connected. <Important details in timber construction>
  • SEMA have created the possibility not to place the board joint in the middle of a post, but between a predefined timber macro. In the case of small timber cross-sections, a double butt joint is often used on the board joint, so that the board joint must be created between the two posts and not in the middle. This option can be activated under “Board joint between member” in the first tab under the master data of the member spacing feature. In addition, it must be determined from which member width on the board joint is no longer centred. If a wall is now calculated with the wall automatism function (F10), the program automatically generates the predefined timber macro on all board joints. In the case of a double butt joint, the reference point must be placed in the middle between the two components when the macro is filed. <Double butt joint>
  • MCAD macros on layer outline edges are now correctly generated on the layer outline with the entry WANDART = DCKBST. (Company Abitare)
  • The name of the edge design for boards is now automatically transferred to the Hundegger Cambium. The field “Name of edge type” is used there for the outline of the board. (Company Stark)

Sheet Metal

  • A new user-defined bend shortening list has been integrated into SEMA. This works by entering your own values. The bend shortening list works with four parameters. Users can adjust the bend shortening according to company and machine-specific values by means of these four parameters. The list can be found in Alt+F7 in the “Evaluation” tab under “Coverings”. <New Features Sheet Metal>


  • Symbols can now be assigned for the top view and for the view in the case of roof and floor panels. In addition, the insertion point can be adapted to the corresponding symbols. Users can find the new options on the second tab “Wall” under the section “Symbolism”.

PHP Machines

  • The length of the file name for the PHP export is no longer limited to 8 characters.
  • The Z-position of boards in walls and roof – floor panels can now be exported for use in Weinmann machines. Consequently, the option “Export Z-position of boards” has been incorporated in the presettings (Alt+F7) under the PHP – import / export system in the Weinmann tab. <Important details in timber construction>

Stair Design

  • From now on, complete staircases and connecting balustrades can be mirrored. The stair shape feature must be marked in order to mirror stairs, and users can insert them mirrored using the familiar “Mirror” command and the self-explanatory and familiar input options. Users can see which (free) axis is to be used for mirroring even during the mirroring process. In addition, a preview of the stairs created is displayed with the correct distance. All fasteners, punching or other manual changes, such as changing the curve of the handrail, are included in all components.
  • It is now possible to fill the resulting gap between the cut string and the riser for the cut string of a bracketed staircase if a riser was created with an offset to the back edge of the tread. To make this possible, the “Des” tab of the cut string has been expanded to include the “Connection cut string / tread” menu item, which can be opened using the “+” button. There are various basic connection options available:

    • “Tread edge” – the cut string is adapted to spiral steps.
    • “Rectangular (short)” – the cut string is connected to a spiral step at right angles so that no mitre areas can arise here.
    • “recta mort HO” – the cut string adapts to the existing riser by notching the projection of the tread in the cut string. The point “Mortise position in cut string” is enabled via this setting. It is determined there whether the resulting notch is adapted to the back edge of the tread or carried out at right angles.
    • “recta mort TR” – the cut string adapts to the riser. A notch for the cut string is created in the tread itself.
    • “Mortise position in cut string” – here, users can set whether the cut string mortise is cut at right angles to a step or bevelled on it.

  • In addition, the machine export has been extended for the settings “recta mort HO” and “recta mort TR”, so that the notches created in the cut string and tread can be given separate edge numbers and can, thus, be treated in a separate processing strategy.
  • The program now provides the option to cut the handrail at the set last step height to deal with last step situations on a staircase. This helps, for example, if it is not possible to connect the handrail to the last step post with a buckling component. Consequently, there is now the setting “Cut off at the last step” in the “Des” tab of the handrail. The handrail is cut at handrail height using the setting “Yes”. The upper edge of the handrail runs in line with the handrail up to the last step post by means of the setting “No”.
  • The manual single adaption of steps has been enhanced with an additional option, with which it is now possible to align the selected step at right angles to the walking line. To do this, users can go to the third option “Single adaption” in the adaption options. After selecting the option, the step desired is selected. The step is automatically set at right angles to the walking line by clicking on the newly integrated switch “Treads front edge vertical to the walking line”.
  • The newel post has been expanded to include the new connection type “Cut top string”. This specifies that the top of the newel post should relate to the top edge of the connected string. It is also possible to set a projection upwards.
  • A new option has been integrated into the stair newel post to shift it in the direction of the balustrade line. In addition, the alignment of the post can be determined in corner situations. Areas of application can be found in corners that do not form an exact right angle. So far, the newel posts have always been set with a bisecting angle in these situations.
    Users can define whether the post relates to leg 1 (direction of first step) or leg 2 (direction of last step) by means of the “Alignment/Orientation” setting. According to the selection, the newel post concerned then rotates to the set leg. The post is now always set with the bisecting angle by using “With bisecting angle”. Users can then set the distance in the direction of the balustrade line in relation to the set legs with “Position of the stairs”. <New Features Stair Design>

Material List

  • The material list transfer (F11) for “Only marked components” has been expanded to include the option “With content”. If one or several walls are marked in the top view, the option “With content” is available for the material list transfer. Marked walls, roof and floor panels as well as construction planes can be transferred directly from the top view, including the respective content, to the material list by means of this new function. <Important details in timber construction>

Single Member

  • From version 22-2, it is possible to export contour processing on timbers with a partner contour during the BTL and BTLX export. The global setting for this is determined during the machine export in the “General settings” under “Export free contour/contours with partner contours”.
    The new option projects the geometry of machining operations that intersect at an angle and penetrate the component on its sides. Thus, it is possible to use a shorter milling cutter length of the manufacturing machine that supports this type of machining.
    If users only want to use this option for individual contour machining, the option can also be selected in the Single Member list with a right-click on the machining.
  • The new module “Machine converter” has been incorporated in co-operation with the company DIREKT CNC-SYSTEME GmbH for the control of simple cross-cut saws .
    The module enables machine data to be generated in *.trs format, which can be read by a wide variety of machine manufacturers.
    In order to be able to use the machine converter, it must be installed as an “Add-on” via the SEMA Datastore. Optionally, this installation package can also be saved as a file.
    The machine converter can be used to export components from the program and the SEMA Single Member feature after successful installation. <Machine converter>
  • Problems when editing processing in the Single Member list regarding the dimensions have been fixed.
  • The BTLX import has been enhanced. (Company Kobelt, Company Zimmermann)
  • The machine export for cutout processing for the BTL and BTLX has been optimized. (Company Caem, Company Moor)
  • The BVX2 export has been improved for scarf joints with the option “With shearing angle”. (Company Mutschlechner, Company Kattenbaum)
  • I-beam longitudinal processing on the timber component was listed as post-processing in a specific case. This has been fixed for the BVX2 export. (Company Hundegger)
  • The export to Hundegger machines has been improved for timbers that have been cut several times. (Company Plantaz)
  • Problems with the machine export of the dovetail connection with air between the individual log planks have been fixed.
  • The conversion of scarf joints into front scarf joints has been made possible for special processing (Company Len)
  • Components with a missing component reference that have been sorted out in the Single Member list end up in the post-processing list during the BTL/BTLX export. (Company Burger, Company Charm, Company Akabois)

Survey Systems

  • As of Version 22-2, it is possible to punch point clouds stored in the project. Users can also employ a clipping box to hide points outside of these points. Consequently, a so-called global clipping box is automatically generated when importing a point cloud. This clipping box affects all point clouds in the BP. It is not initially visible in the standard settings of the SEMA program and is not active either. Users can also punch a point cloud from different views via the normal punch command. These views include, for example, the wall view, sections and top view. If the point cloud is marked, these punch boxes can be switched to visible via “Mark object details”.
    If the clipping or a punching box is marked, a gripper in the form of an arrow appears on the various surfaces of the ashlar. Users can now move the respective side by a specific negative or positive measure by clicking on the arrow and using the mouse. It is also possible to move the clipping or punching box after marking. This type of processing can be carried out in all views and directly in the 3D mode.
    If the position or size of the clipping or punching box is changed, users can see directly what the point cloud looks like after completing the command.
    As soon as the clipping box is reduced to a specific area, it is possible to display the point cloud within this area more densely than the original cloud, since the total number of points to be displayed is automatically adjusted.
    The F7 menu under “3CAD”, “Point clouds” has been expanded to include the “General” tab so that the effect and visibility of these boxes can also be changed. The options “Top view”, “Section” and “3D” are available here. These options influence the visibility of all imported point clouds in the respective views. The settings for clipping can also be found here. The buttons “Clipping active”, “Punch-clipping active” and “Clipping box visible” can now also be found in the toolbar “Survey System” for the direct activation/deactivation of the switch desired.
    The effect of the clipping box can be switched on or off with the setting “Clipping active”. The option “Punch clipping active” influences the effect of the punching boxes separately. The clipping box can be switched to invisible via the “Clipping box visible” switch.
    If the button “Highlight cut surfaces of the clipping” is activated in F7, the colour of the respective direction is displayed on each cut surface of the point cloud with the clipping box: red = X-axis, green = Y-axis and blue = Z-axis.
    All settings made in the “General” tab can be restored for all projects in the start settings or user-defined F7 settings, such as for plans. <Point cloud clipping>
