Technical Drafting, 3D Spatial Modeling, and Architectural Visualization Services

We specialize in digital drafting, 3D geometric modeling, and high-resolution architectural visualization for interior designers, landscape architects, and urban planners. Our technical team renders accurate three-dimensional models to analyze sunlight angles, shadow behaviors on facades, and space utilization before physical construction begins.

Applied Technical Capabilities

Precision modeling and simulation services that inform real-world design decisions before ground is broken.

Solar Geometry & Shadow Analysis

We model exact sun paths for any latitude to calculate facade exposure, overhang effectiveness, and seasonal shadow bands. Deliverables include hourly irradiance maps and overshadowing diagrams for adjacent structures.

Parametric Space Utilization

Geometric modeling of floor plans and public spaces to test furniture layouts, pedestrian circulation widths, and sightline cones. We quantify usable area ratios and identify dead zones before interior or landscape design finalization.

High-Resolution Visualization & Glare Mapping

Physically based renderings with accurate material reflectance and glazing transmission. We produce luminance maps to pinpoint glare sources and recommend shading strategies, preserving daylight while maintaining visual comfort.

Facade Tilt & Overhang Optimization

Iterative 3D modeling of brise-soleil, horizontal louvers, and vertical fins. We test angle variations to balance solar gain reduction with outward visibility, providing comparative charts for each design option.

Agent-Based Pedestrian Simulation

Crowd flow modeling for plazas, lobbies, and transit concourses. We calibrate walking speeds and density thresholds to predict bottleneck locations and egress times under normal and peak load conditions.

Daylight Autonomy & Energy Correlation

Climate-based annual simulations that link spatial daylight autonomy (sDA) with cooling and lighting load estimates. Results are delivered as zone-level heat maps and summary tables for compliance with green building criteria.

Ready to move from concept to construction?

One accurate 3D model eliminates guesswork — we deliver shadow simulations, spatial analysis, and high-res visualizations before a single foundation is poured.

“The shadow simulation for our coastal villa was remarkably precise. We adjusted the roof overhang based on their solstice data — it cut cooling costs noticeably.”
Elena Marais Principal Architect, Marais Studio
★★★★★ 4.8
“Their pedestrian flow model helped us reconfigure the plaza layout before breaking ground. Congestion dropped 30% in the simulation — a huge win for the city.”
Thabo Nkosi Urban Planner, Cape Town Municipality

Frequently Asked Questions

What file formats do you deliver for 3D models?

We export models in industry-standard formats including .DWG, .RVT, .SKP, .FBX, and .OBJ. For architectural visualization, we provide high-resolution renders in .PNG and .TIFF. If you need a specific format, let us know during the project kickoff.

How accurate are your sunlight and shadow simulations?

Our simulations use precise geographic coordinates, site-specific topography, and real solar data for any given date and time. We model shadow behavior at 15-minute intervals across solstices and equinoxes, achieving an accuracy margin of ±2% compared to on-site measurements.

Do you work with interior designers and landscape architects directly?

Yes. We collaborate directly with interior designers, landscape architects, and urban planners. Our team adapts to your workflow, whether you need a full 3D model from scratch or a refined visualization based on your existing sketches and CAD files.

What is the typical turnaround time for a residential facade study?

A standard facade sunlight analysis for a single-family home takes 5 to 7 business days from model creation to final report. Complex multi-building urban studies may require 10 to 14 days depending on the number of design iterations.

Can you incorporate existing BIM data into your models?

Absolutely. We import BIM data from Revit, ArchiCAD, and IFC formats. Our team cleans and optimizes the geometry before running spatial or daylight analyses, ensuring that your existing model structure is preserved and enhanced with our simulation layers.
