3 - Use the "Aligned Dimension" command to add distance measurements between the newly created plans and the default ones.

Annotate > Dimension > Aligned Dimension

4 - Using the "Extrusion" command and the "Rectangle" tool, create a rectangle. and then align it with the four reference planes. Ensure that the sides are locked to the reference planes to secure their position.

Create > Forms > Extrusion > Rectangle Tool

5 -  Align it with the four reference planes using the "Align" tool. Ensure that the sides are locked to the reference planes to secure their position.

Modify the Extrusion > Align and the lock with the "Lock Icon"

6 -  Go to 'Front View' and create a new reference plane. As before, use the 'Aligned Dimension' tool to add a measurement. Then, align the top face of the extrusion with the reference plane.

7 - Open the 'Family Types' dialog and add the shared parameters 's_widtht,' 's_length,' and 's_thickness. Make sure the parameter type is "Length" and the "Instance" parameter type selected. Next, add the parameter 's_text,' set its type to 'Text,' and ensure the 'Occurrence' option is selected.
