Build a stud partition or a joist floor
The Stud frame and Joists generators lay out timber at the centres you give. They are advisory layouts only. KerfCraft does not check spans, loads, fixings or Building Regulations. Get structural design for anything load-bearing.
Start a stud frame#
- Click Library… in the toolbar.
- Under Built from parameters, click Stud frame.
KerfCraft inserts a stud frame at a standard size and selects it. You can also open File ▸ Sample projects ▸ C24 stud partition with door.
The assistant can also lay out a frame, for example "a 3 m long, 2.4 m high stud partition at 400 centres".
Change the stud frame#
- Select the frame.
- In the Properties panel, under Parameters, change a value and press Enter.
| Parameter | What it sets |
|---|---|
| width | The length of the frame along the wall |
| height | The overall height, plates included, at the left end |
| heightRight | The height at the right end, for a sloped head plate. 0 is a level head |
| profileId | The timber profile for all members |
| spacing | The stud centres. The default is 400 mm |
| nogginRows | The rows of noggins in each bay |
| nogginStagger | inline, or staggered for end-nailing |
| cornerLeft, cornerRight | threeStud or california corner members where another frame meets this one |
Add a door or window opening#
In openings, type each opening. Put a ; between two openings:
- A door:
door:x=600,w=826,h=2040 - A window:
window:x=1500,w=900,h=1050,sill=900
The value x is the distance from the left outer edge of the frame to the opening. The values w and h are the width and height of the opening. The value sill is the height of the bottom of a window opening. Each side needs space for a king stud and a jack stud.
The heads over openings are doubled flat members of the frame timber, not designed lintels. The frame shows this warning.
Start a joist floor#
- Click Library… in the toolbar.
- Under Built from parameters, click Joists.
KerfCraft inserts the joists at a standard size and selects them. Change them in the Properties panel, under Parameters.
The assistant can also lay out joists, for example "floor joists 3.6 m span, 2.4 m wide, at 400 centres".
Change the joists#
| Parameter | What it sets |
|---|---|
| span | The length of the joists, rim boards included |
| width | The width across which the joists repeat |
| profileId | The timber profile for all members |
| spacing | The joist centres. The default is 400 mm |
| rim | both adds rim boards across the joist ends |
| opening | One trimmed opening, for example x=800,y=1000,w=900,l=1200 |
The opening is in mm from the origin of the frame. The value w is along the width, and l is along the span. KerfCraft doubles the trimmers and trimming joists round it.
Before you cut#
The Derived heading shows results such as the joist count. Check every dimension against your own measurements before cutting.
