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 Thickness – Roof+M will automatically create new type for selected family with new depth equal to selected roof layer thickness.
Rotate 90°, Rotate 180°
Rotate 90°, 180° – joist can be rotated 90/180 degrees to its initial position.

Distance/Spacing, Spacing and Number
Distance/Spacing – predefine the distance from selected position (selected joist, roof 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 – choose whether joist should be applied in the center-centered, center-sided, external, or internal side of the frame.
