How to cut a separate Notch in a stud or track?

Prepare the family

1. Download the family

1. Choose one of the families below:

Imperial family:

436KB

I_SC_Notch.rfa

Open

Metric family:

436KB

M_SC_Notch.rfa

Open

1. Drag and drop the family into the project.

The family is saved in Revit 2023 and belongs to the Structural Connection category.

If you work with newer Revit versions, you can easily upload and upgrade the family in your project.

2. Select the type by CNC machine name

Currently, the family contains types for three CNC machines - Arkitech, Howick and Pinnacle:

Each type contains parameter values designed for a specific CNC brand:

Warning: Do not change the CNC Type

Note: if the required notch punch name is different from the default NOTCH or you have a specific notch tool name for separate notch cuts, you can change the CNC Command parameter value.

The value you enter will appear in the exported CNC file.

3. Create new type

The default sizes are:

• Imperial: 3 1/2" (web) x 1 5/8" (flange)

• Metric: 89mm (web) x 50mm (flange)

If you need a new size, follow the steps:

1. Duplicate the family type

2. Rename to the appropriate size

3. Change d and/or bf parameters in the type parameters

4. Click OK:

Recommendation: the notch hole size should match your stud profile. For example, if your stud is 600S162 (6" web x 1 5/8" flange), the Notch family type should have these type parameter values:

d = 0' 6"

bf = 0' 1 5/8"

Insert manually

1. Drag and drop the type

1. Open a plan view showing the track component you want to cut

2. Drag the family type from the project browser

3. Insert the notch onto a selected track:

Note: the Notch family is a face-based family and the selected stud or track will be the host.

Tip: if you're having issues placing the family, try hiding the wall temporarily.

1. Adjust the notch position in the stud or track:

2. Cut a custom-sized hole

If you need to create a hole in a track of a custom size, you'll need to place multiple notch instances adjacent to each other.

Some notches may overlap - that's because the notch punch has a certain size that is already set up in your CNC machine.

For example, if your notch size is 1 5/8" but you need a 4" hole, you'll need to insert three notches and some will overlap:

1. In the plan view, draw the boundaries of the 4" hole on the track (recommended)

2. Insert holes

3. Align the holes with the boundaries using Move tool

In the exported CNC file, the notch command locations on tracks will match the red crosses at the centers of the family instances:

3. Adjust the instance parameter values

Adjust these parameters for each inserted notch

• Framing Layer = Frame

• Framing = Wall

• Framing Member Mark = any combination of letters (e.g. HO)

• FM HostMemberSortMark = [instance Mark parameter value of the framing host wall]

• #bf = bf (flange) type parameter of the notch host track (C+C_CH Plate)

• #tf = tf (thickness) type parameter of the notch host track (C+C_CH Plate)

4. Number elements

1. Navigate to Wall+M

2. Click on Number Elements

3. This command will input the data for the FM Sort Mark parameter:

Warning: Number Elements command will renumber all Structural Framing (studs, tracks, etc) and Structural Connections (angles, anchors, etc) in the entire project.

If you don't want to renumber all other elements too, you can enter the values into FM Sort Mark manually.
