3D CITY PLANNING: TOOL AND SCENARIO WORKSHEET
Guide: https://yenra.com/3d/city-planning.html
Template checked: October 3, 2026

How to use: Save one project copy; preserve a dated revision for each
formal comparison. Replace bracketed fields. Record units and source
references next to values. Keep the fictional example separate from your
project results. This is a planning record, not a vendor model or a local
planning-compliance calculation.

1. QUESTION AND DELIVERABLE
Project / owner / reviewer: [ ]
Decision this comparison should inform: [ ]
Site boundary and area (units): [ ]
Required output (metrics / images / walk-through / web viewer): [ ]
Audience and accessible alternative to interactive 3D: [ ]

2. TOOL SELECTION
Candidate and version/service checked: [ ]
Official documentation URL and check date: [ ]
Required input formats, attributes and coordinate support: [ ]
Required output/export format and sharing route: [ ]
Team skills / training / hardware requirements: [ ]
Authoring seats, viewer access and cloud/data terms: [ ]
Representative import/export test and result: [ ]
Reason for selection and remaining limitation: [ ]

3. DATA INVENTORY (repeat for each dataset)
Dataset and source URL/file: [ ]
Capture/survey date and revision: [ ]
Coordinate reference, units, height reference and origin: [ ]
Accuracy information and missing/estimated fields: [ ]
License and permitted sharing: [ ]
Transformations and validation point/dimension: [ ]

4. FICTIONAL CHECK EXAMPLE -- DO NOT USE AS PROJECT DATA
Site area: 10,000 m2.
A: 3 buildings x 1,000 m2 footprint x 4 full floors = 12,000 m2 GFA.
B: 2 buildings x 750 m2 footprint x 8 full floors = 12,000 m2 GFA.
Both: gross floor area / site area = 1.2.
A total footprint: 3,000 m2; remaining site: 7,000 m2.
B total footprint: 1,500 m2; remaining site: 8,500 m2.
B leaves 1,500 m2 more site outside building footprints.
Assumptions: identical full floor plates in each building; no setbacks,
voids or excluded areas. Remaining site includes servicing, circulation
and other uses; it is not automatically usable green space. Actual area
definitions must be checked for the project. These results say nothing
about shadow, wind, access or approval without further work.

Metric / definition / method / A result / B result: [ ]
Area reconciliation check and result: [ ]
Additional analysis tool, method, version and settings: [ ]
Location, date, timezone and environmental assumptions: [ ]
Matched camera and lighting identifiers: [ ]
Sensitivity to uncertain inputs: [ ]

6. AI AND PRESENTATION RECORD
