What it does

Preliminary CSA O86 based wood connection workflow for hold downs, uplift ties, joist hangers, collector straps, wood screw groups, bolt groups, and anchor to concrete review placeholders. Compares factored demands to source tagged connector or fastener capacities, tracks installation requirements, flags missing data, and exports structured handoff results.

What it does not do

Placeholder connector capacities are not final design values. Full manufacturer lookup, proprietary interaction equations, eccentric fastener group design, concrete anchor design, fire design, and seismic capacity protected connection design are not implemented in this phase.

How to use it

Use for preliminary connection demand tracking, review planning, and source controlled connector selection only. Verify all capacities, fastener schedules, installation requirements, anchorage, edge distances, and manufacturer data before project use.

Use Wood Connection and Hold Down Designer in your own projects

Every tool ships inside the CoLateral desktop workspace, so a result can stay attached to the project, the drawing, and the review trail it belongs to instead of ending up in a loose spreadsheet.

Outputs are design aids and stay in draft until a qualified engineer reviews and approves them.
