This is the convention for metric work, and what to do when a file turns up and you cannot tell what it is in. The rule: … [Read more...] about Metric Units in CAD: mm, m or km, and Why It Matters

Structural Slab Joints: Types, Abbreviations, Drafting
Concrete moves. It shrinks as it cures, it expands and contracts with temperature, and different parts of a structure settle by different amounts.
