ZA.1 South African market: SANS 10143 drawing practice + SANS 10400 building regulations

Sell into South Africa: local practice draws to SANS 10143 (building drawing practice) and builds to SANS 10400 (National Building Regulations). Full note for the 2026-10-26 meeting: docs/0.8-ZA-STANDARDS.md.

Today: no SA support. BimCraft residential is hard-coded to US codes (res-stair.js IRC stair limits, res-framing.js 2x lumber + US header table, US egress window, US electrical symbols).

Suggested order:
1. Built on REG.1: regulations by jurisdiction as library packs; ZA.1 delivers the South African country packs.
2. SANS 10143 drawing pack: metric mm dims, levels in m, A-series sheets, SA title block (erf, SACAP reg. no.), hatches, symbols, D1/W1 marks.
3. SA residential defaults: 230/280 cavity masonry, SA brick and block, 38x114/38x152 timber, trusses, IBR/tile roofs; Part M stair and Part O window-area checks.
4. Part XA energy check (climate zones 1-6, fenestration, R-values) and an SA municipal submission set export. The differentiator.
5. CivilCraft: Hartebeesthoek94 Lo zones with the Y-westing / X-southing axis flip; SANS 10142 electrical symbols.

Business: SANS texts are copyrighted (buy, encode, cite clauses, edition dates); POPIA; ZAR + 15% VAT, regional pricing?; offline/load-shedding is a selling point.

Meeting questions: 0.8 market or later? Buy the SANS set? An SA reviewer? Regional pricing? Drawing pack or XA first? Afrikaans?

All SANS figures are from memory; check against purchased copies before shipping.

LAB SAMPLE (2026-10-25): a small South African pack (stairs, room height, window and openable area) can be seen in /lab/bimcraft under Settings > Building regulations. Its numbers are unchecked.
