# Reading a Plan Set, Step by Step
A set of plans can look overwhelming. Take it one step at a time and it becomes a simple roadmap.
## 1. Start at the cover / index
The first sheet lists every drawing in the set. Sheets are usually grouped by letter:
- **A** = Architectural · **S** = Structural · **C** = Civil/site
- **M / E / P** = Mechanical / Electrical / Plumbing
## 2. Read the title block
The box in the corner of every sheet tells you the **project, sheet number, date, and the scale**.
## 3. Find the floor plan and get oriented
The **floor plan** is a view looking straight down. Find the **north arrow** to orient yourself.
## 4. Use the scale
Drawings are shrunk to **scale** (e.g., ¼" = 1'-0"). Use the noted scale or an architect's scale to measure real distances — but always trust written **dimensions** over measuring the drawing.
## 5. Follow the dimensions
**Dimension lines** (with arrows and numbers) tell you exact sizes and spacings. Add them up to check they total correctly.
## 6. Use the legend and symbols
A **legend** explains the symbols (doors, windows, outlets, fixtures). Learn the common ones.
## 7. Chase the details
A **callout bubble** (a circle with numbers) points you to a **detail** on another sheet that zooms in on how something is built.
## 8. Read the notes and specs
**General notes** and the written **specifications** control materials and quality — don't skip them.
**Takeaway:** Work a plan set in order: index → title block → floor plan → scale → dimensions → legend → details → notes. Trust written dimensions over measuring.
