Add Additional Joist – adds additional joist into selected frame with predefined settings. 


Additional Joist sizes


Type – select the family and type that will be used for joist. 


Width (b) – shows b size of selected type.


Depth (h,d) – shows h or d size of selected type. 


Define Depth (h,d) by Layer ThicknessFloor+M will automatically create new type for selected family with new depth equal to selected floor layer thickness. 


Rotate 90°, Rotate 180°


Rotate 90° – joist can be rotated 90 degrees to its initial position. 


Rotate 180° – joist can be rotated 180 degrees to its initial position.


Rotate 90° is ticked:

Insert Direction from Selected Joist


Insert Direction from Selected Joist – predefine insertion direction left or right of selected joist. 


Example: Additional joist is inserted to the left of selected joist:


Distance Lock to


Distance Lock to – an additional joist can be inserted with predefined distance from selected joist, floor start/end, or selected external element.


Distance/Spacing, Spacing and Number


Distance/Spacing – predefine the distance from selected position (selected joist, floor start/end or selected external element) to additional element.


Spacing – the distance between joists.


Number – the number of joists.


Example: Two additional joists were added to the right side of selected joist with predefined distance and spacing:


Frame Side


Frame Side – choose whether joist should be applied in the center-centered, center-sided, external, or internal side of the frame.  


Build in Place


Build in Place – writes Yes/No information into the joist instance parameter if it is build-in-place or is prefabricated with whole floor frame. This parameter can later be used in schedules or view filters.
