Detailed documentation
Models don’t show everything. Learn to add 2D detailing on top of model views, build legends and keynote legends, and produce documentation a builder can use.
In this lesson you will
- Combine model views with 2D detailing
- Use detail components, filled regions and repeating details
- Create drafting views and legends
- Keynote consistently and check a set
Model plus detail
A 1:5 wall detail is usually a callout of a section: the model provides the walls, floor and roof in correct positions, and you add 2D detailing on top — flashings, fixings, sealant, labels. Detailing belongs to that view only.
Detailing tools
- Detail Line (DL): 2D lines in a line style.
- Detail Component (Annotate): 2D families of standard items — timber sections, fixings, blocks — that scale correctly and can be keynoted.
- Repeating Detail: a component repeated along a line — brick courses, blocking.
- Filled Region: a hatched or solid area — insulation, grout, earth.
- Insulation: the batt insulation tool.
- Masking Region: hides model geometry beneath.
Drafting views and legends
Drafting views are purely 2D views for standard details not tied to the model (you can import legacy CAD details into them). Legends show symbols and element types — a door type legend with elevations of each door, or a wall type legend — and can appear on many sheets.
Keynoting
Keynotes read a text keynote file with codes (often organised to match specification sections). Tag elements, materials or user keynotes, then add a Keynote Legend to the sheet (By Sheet lists only the keynotes used there). One source of wording, used across the set.
Checking the set
Before issue: every callout and section references a placed view; view titles and scales are right; no working views on sheets; keynote legends complete; revision clouds and tables current; export and check the PDF.
Quick reference
| Command / tool | How to start it | What it does |
|---|---|---|
| Detail Line | DL | 2D lines in a view |
| Detail Component | Annotate tab | 2D detail families |
| Filled Region | Annotate tab | Hatched 2D regions |
| Drafting View | View tab | 2D-only views |
| Legend | View › Legends | Symbol and type legends |
Common mistakes
Detailing a section with lines that duplicate model geometry.
Let the model show what it can; detail only what isn't modelled.
Keynote legend shows every note in the project.
Use a By Sheet keynote legend.
Exercise
A documented wall detail
- Create a 1:5 callout of your wall section at the eaves.
- Add detail components for timber and fixings, filled regions and insulation.
- Keynote five items and add a By Sheet keynote legend.
- Place it on a details sheet and check the callout reference.
You should end up with: A keynoted detail correctly referenced in the set.
