Framing Configuration may be found in two locations: 


Common Joist

Type – select the family and type that will be used for joists. Default value comes from the Common Settings tab.

Width (b) – shows width of selected type.

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

Define Depth (h,d) by Layer Thickness – Floor+ will automatically create a new type for the selected family with new depth equal to the thickness of the selected floor layer. 

Add Joists – joists with rules listed below Add Joists in the menu (i.e. Align with Project Base Point, Joist Spacing, First/Last Spacing) will be (not) applied to the frame. The frame can be created without joists, just using, for example, horizontal elements. 

Align with Project Base Point

Align with Project Base Point – allows joists to be positioned not only in relation to each other but according to Revit gridlines.

First step – unclip the state of the Revit Project Base Point and move it to the needed position: 

For more convenience, switch on Revit Work Plane and move it to the Project Base Point. It will help you to understand if the studs or joists are created in the right position: 

Turn on Align with Project Base Point in the Framing Configuration dialog:

Frame the walls, floors, or roof.

Joists are positioned on the gridlines – and where necessary to fill in gaps or form intersections – so that they always match up across a corridor or room.

Notice how the joists are spaced according to the grid.

In case you need to relocate the frame, just move the Project Base Point to the new position and update the frame!

Joist Spacing and First/Last Spacing

Joist Spacing – defines the distance between joists.

First/Last Spacing – first spacing will be on the side of the span direction line, and last on the opposite side

Rim Joist 1/ Rim Joist 2

Type – select the family and type that will be used for rim joists. Default value comes from Common Settings tab.

Rotate 90° – if ON, then rotates rim joist by 90 degrees.

Number of Elements – inserts a defined number of rim joists into the frame.


1 – Rim joist 1, Number of Elements = 1

2 – Rim joist 2, Number of Elements = 2

Number of Elements not to Cut

Number of Elements not to Cut – if there is at least one rim joist 1, you can cut it or leave it as a whole.

Top Cover/Bottom Pad Type

Top Cover/Bottom Pad will be added above/below the main frame. 

Top Cover/Bottom Pad Type – select the family and type to be used for pad. Suggested family is I_WF Rim-Bridging Joist.rfa (in Imperial projects) and M_WF Rim-Bridging Joist.rfa (in Metric projects). These families will be loaded into the project with other sample Floor+ families. 

Number of Elements – select if the top/bottom pad should be added and select an amount of lines. 

Number of Rows – select an amount of pad elements in one line.

Build in Place

Build in Place – writes Yes/No information into the top/bottom plate instance parameter if it is built in place or is prefabricated together with the whole floor frame. Later this parameter can be used in schedules or view filters.  


Offset – frame offsets from floor end or base.
