Roof framing cutting list — from model geometry to workshop organization.
A useful cutting list is not just a table of lengths. It should identify the real framing elements, their sections, quantities, preparation data and relationship to the project.
What belongs in a cutting list?
- element ID or mark,
- element type,
- timber section,
- length and measurement reference,
- quantity,
- roof surface or location where useful,
- link to notch/end-cut information,
- status or grouping for workshop organization.
Real elements vs theoretical geometry
If a roof opening interrupts a rafter, the list should represent the physical pieces that will actually be prepared. Keeping an imaginary full-length rafter in the workshop list can create material and production errors.
Grouping identical pieces
Identical elements can be grouped by section, length and geometry, but only when the workshop operations are truly the same. Different cuts or mirror orientation may require separate IDs even when the raw length matches.
PDF and workshop cards
The cutting list is most useful when it links to more detailed information. A PDF can summarize the project, while a workshop card can show the specific geometry of one member. QR identification can make it easier to connect the physical piece with its digital record.
Material ordering and CNC handoff
The cutting list also provides a structured starting point for ordering timber or discussing prefabrication. Machine-specific CNC formats depend on the production system, so the cutting list and element cards should be treated as organized source data rather than a universal machine file.
Cutting lists in Krokwio
Krokwio generates its element information from the same project used by the 2D/3D model. That helps keep IDs, dimensions, cards and documentation aligned as the project changes.

Practical roof framing cutting list example
A workshop list should distinguish geometry from purchasable or cut timber. One line might read: R-01 — common rafter — 45 × 195 mm — 4,880 mm reference length — quantity 8. The listed length is illustrative: verify the actual cut length against support, ridge and overhang details before production.
How to make the list usable on site
Assign unique IDs to distinct cut geometries, even where pieces have similar lengths. Match each ID to its element card and cutting drawing, and state the unit of measure. Group truly identical pieces to simplify packing and fabrication without losing traceability.
