This Autocad For Engineering Drawings spreadsheet from 3D-LABS follows IS code and gives instant, checkable results for practising engineers — no manual derivation required.
AutoCAD for Engineering Drawings — IS 696 / SP 46 covers AutoCAD 2024 drawing production following Indian Standards IS 696:1972 and SP 46:2003 — from IS-compliant template setup through first-angle projection, sectioning, dimensioning, surface finish symbols, tolerance annotation, and welding symbols. Written for mechanical and civil engineering draughtsmen in India.
What Indian drawing standards does this book cover?
IS 696:1972 comprehensively: first-angle projection (standard in India), line types and weights (visible lines 0.5 mm, dimension lines 0.25 mm, hidden lines 0.35 mm dashed), lettering sizes (3.5 mm for dimensions on A3, 5 mm for titles), section hatching 45 degrees at 3 mm spacing. SP 46:2003: limits and fits (H7/g6, H8/f7 hole-basis system), surface finish Ra in micrometres, and welding symbols per IS 813:1991.
What AutoCAD template setup is covered for IS-compliant drawings?
AutoCAD template setup: units in mm, sheet size limits for A0 (1189×841), A1 (841×594), A2 (594×420), A3 (420×297), A4 (297×210). Layer names per IS 696 conventions: IS_VISIBLE, IS_HIDDEN, IS_DIMENSION, IS_CENTRE, IS_SECTION. Title block with drawing number, revision, scale, first-angle projection symbol, material, and drawing authority per BIS recommendations.
What limits and fits annotation is covered for IS practice?
Hole-basis system per SP 46:2003: H holes (fundamental deviation = 0), shaft codes (f, g, h, js, k, m, n), tolerance grades IT01 to IT18. Example annotation: 50H7/g6 — hole +0/+0.025 mm, shaft -0.009/-0.025 mm = clearance fit. Surface finish Ra target by machining process (e.g. turning Ra 1.6-6.3 micrometre, grinding Ra 0.1-0.8 micrometre) annotated using ISO 1302 symbol set.
