Where we help
From a code review to a complete application
Projects can begin with an existing codebase, a reproducible defect, an integration requirement, or a new product brief. The first step is to define the specific technical and user result.
OCCT3D can work with a customer team or take responsibility for an agreed work package. Scope, deliverables, and acceptance checks are documented before implementation.
Services
Select the work you need
Each area can be commissioned separately or combined into one delivery plan.
Consulting
Review the architecture before changing it
Independent technical review for an existing CAD application, a planned product, or a difficult performance problem.
Architecture review
Application boundaries, data models, deployment constraints, and integration risk.
Solution analysis
Code structure, use of OCCT, maintainability, and the risks behind the current design.
Performance analysis
Profiling with representative models to locate CPU, memory, I/O, and rendering bottlenecks.
On-site consulting
Workshops, design sessions, and focused problem solving with the customer team.
Typical output: findings, priorities, and an implementation plan tied to the reviewed system.

Build complete 3D applications or focused product features
Engineering for desktop, web, mobile, and industry-specific CAD, CAM and CAE software, including OCCT-based solutions.
Desktop applications
Native Windows, Linux, and macOS tools for geometry-heavy engineering workflows.
Web solutions
Browser-based visualization and processing using WebGL, WebAssembly, and server-side services where needed.
Mobile applications
Touch-oriented viewing and field workflows for iOS and Android.
Industry software
CAM, metrology, simulation, inspection, and other domain-specific applications.
Typical output: a tested application or product increment with source code, documentation, and release guidance.
Explore development servicesBug fixing
OCCT bug fixing and performance optimization
Investigate a reproducible case, then agree on any correction and regression checks.
Critical corrections
Crashes, incorrect results, data loss, and production failures in OCCT-based software.
Performance corrections
Slow operations, excessive memory use, and rendering bottlenecks measured on real workloads.
Feature improvements
Changes to existing behavior checked against agreed regression cases.
Version migration
API updates and behavioral changes required when moving to a newer OCCT release.
Possible deliverables, as agreed: investigation findings, a proposed correction, and regression checks.
Explore bug fixing servicesSupport
Add specialist capacity to an existing team
Short questions, scheduled consulting, and longer technical work can use the same support-unit package.
Algorithm guidance
Help selecting, combining, or implementing geometry algorithms for a product requirement.
Visualization support
Rendering architecture, selection, interaction, performance, and visual diagnostics.
Platform porting
Build, dependency, compiler, and operating-system work for supported deployment targets.
Project maintenance
Planned updates, code review, troubleshooting, and release assistance.
Typical output: answers, investigation notes, reviewed changes, or implementation work charged against the agreed package.
Explore support servicesIntegration
Connect 3D technology to the rest of the product
Integration work covers data exchange, product systems, cloud services, and user-facing workflows.
CAD and CAM
Geometry, assemblies, attributes, and manufacturing data across engineering systems.
PLM and enterprise systems
Product structure, metadata, revision context, and controlled document flows.
Digital twins
Link engineering geometry with operational, inspection, or asset information.
Online 3D experiences
Model preparation and visualization for configurators, catalogs, and customer portals.
Typical output: a documented integration boundary, working adapters, and tests using representative data.
Explore integration servicesCustomization
Adapt existing CAD software to a specific workflow
Targeted changes to CAD software, algorithms, interfaces and integrations where an off-the-shelf component is not enough.
Workflow changes
Commands, validation, automation, and interaction designed around the actual operating process.
Performance tuning
Changes for model size, throughput, hardware, or latency constraints specific to the product.
Third-party extensions
Commercial data exchange, specialist solvers, rendering systems, and internal services.
Domain specialization
Geometry rules, terminology, metadata, and outputs for a particular engineering field.
Typical output: a maintained product extension with explicit compatibility and upgrade boundaries.
Explore customization servicesHow the work runs
From scope to handover
The detail changes with the engagement, but the delivery sequence stays easy to review.
- 01
Scope
Agree on users, representative data, target platforms, constraints, and acceptance checks.
- 02
Technical proof
Test the highest-risk path before expanding the implementation.
- 03
Delivery
Build in reviewable increments with tests, documentation, and regular demonstrations.
- 04
Handover
Prepare release notes, upgrade guidance, and clear ownership for continued maintenance.
Choose a starting point
Review an existing application or scope a new one.
Bring the current code, a representative model, or a short product brief. The next step is a bounded technical discussion.
