Custom 3D Software for Engineers

We help engineers and technical teams communicate, test, and train ideas faster using interactive 3D software.

Think simulations, trainers, and visual tools — built specifically for your problem, not a generic product.

The Problem We Solve

Engineers have great ideas.
They’re just hard to explain.

Most ideas live in:

  • Spoken explanations

  • Dense documents

  • Flat drawings

  • Expensive, slow prototypes

These tools work — but they’re slow, non-intuitive, and easy to misunderstand.

Misunderstandings cost time.
Time costs money.

Our Solution

We build small, custom software tools that let people see, interact with, and experience an engineered idea in 3D.

Instead of explaining an idea, you walk someone through it.

Instead of guessing, you interact with it.

What Makes Us Special

Each developer is a mechanical engineer, who is also a capable Programmer.

That matters.

Most custom software requires:

  • A software engineer

  • An engineer to explain the problem

  • A manager to translate between them

We can do all three with one person.

We understand:

  • Engineering constraints

  • Engineering workflows

  • What engineers actually need from tools

That lets us build better software faster and cheaper.

What Makes Our Software Special

  • High-fidelity graphics (Programmed with Unreal Engine 5)
    Fewer abstractions. Fewer misunderstandings.

  • Multi-platform
    VR, PC, and in some cases web & mobile — at the same time.

  • Multi-user
    One person or an entire team, collaborating live.

  • Unlimited internal licenses
    If we build it for you, your whole team can use it.

  • Integrated AI
    AI agents for simulation and AI assistants inside the software to help users learn faster.

Examples of our Work

Example Projects We Have Completed

VR Chemistry Lab

Taught what endothermic & exothermic reactions are.

Fire Extinguisher Training

Taught how to use a fire extinguisher with a stand alone VR headset.

VR Geiger Counter Training

Taught how to practically use a Geiger Counter to find contamination.

Emergency Evacuation Policy Training

Taught corporate policies for performing an emergency evacuation of a building.

Means-of-Egress Simulations with AI Occupants

Engineering simulation tool to automatically find and view the best way to egress from a building in an emergency with the ability to place obstacles and features in the building to evaluate how they change evacuation times.

3D Flame Height Calculator

3D calculator that allowed a user to enter the energy output of a fire in KW and visually see the flame height. This allowed the user to gain an emotional connection with what the output of the equation meant.

Interactive Digital Museum

Demonstrated how viewing designs in a interactive 3D space can increase deeper understanding.

Interactive Greenhouse Product Walkthrough

Allowed customers to plan out a greenhouse prior to purchase which increases chance of sales.

Video Making Software

Allowed a business to rapidly produce videos of their high priced product in their clients backyard to help their client emotionally visualize what the product would look like before buying.

Architectural Visualization

Allowed stakeholders to view and collaborate about a new building design.

Fluid Simulator for Fire and Smoke

High fidelity graphic fluid simulator of how a fire bends around a mezzanine.

Small Software, Big Leverage

Until recently, custom software was expensive and slow.

Today, with modern tools and AI:

  • Small software is viable

  • Custom tools make economic sense

  • Even niche problems are worth solving

We focus on micro-software:
Targeted tools that solve one real problem extremely well.

Often for a few thousand dollars — not millions.

Why 3D (and VR) Matters

Humans understand space faster than spreadsheets.

We’ve personally seen design issues missed in 2D reviews that were obvious the moment the product was seen in 3D — after it was already built.

3D and VR let you:

  • Catch errors earlier

  • Communicate ideas clearly

  • Reduce costly rework

  • Make better decisions, faster

NASA uses this exact approach — for collaboration, approval, and training — with Unreal Engine.

Why VR Trainings are a Good Match

VR trainings offer safe, immersive, cost-effective simulations that enhance learning, reduce errors, and improve retention in complex industrial environments.

Why Custom High Fidelity Graphic Engineering Simulations

High-fidelity Graphic Unreal Engine 5 simulations provide realistic visuals, accurate physics, better decision-making, and immersive training for engineering applications.

Free Concept Demos

If you’re not sure whether custom 3D software would actually help, we offer free small concept demos. You describe a problem, idea, or workflow, and we’ll build a simple interactive visualization or prototype to show what’s possible — no commitment required. The goal isn’t to sell you software; it’s to let you see whether this approach would save time, reduce confusion, or catch issues earlier. If it’s useful, we can talk about next steps. If not, you still walk away with a clearer understanding of your idea. If you’re interested, reach out at JR@CatchSunlightTechnologies.com.

If You’re Asking…

“Could software make this clearer, faster, or cheaper?”

The answer is usually yes.

Let’s talk.
