From intelligent geometry analysis to enterprise system integration – we build AutoCAD plugins that solve real engineering challenges.
Our geometry analysis plugins understand structural elements, mechanical assemblies, piping systems, and architectural components. They perform intelligent calculations that would take hours manually – concrete volumes, formwork areas, rebar quantities, material weights, load distributions, and code compliance checks.
We build bidirectional integrations where changes in AutoCAD automatically update your ERP, and procurement data flows back into drawings. Whether it's syncing equipment specifications to SAP, pushing bills of materials to Oracle, or connecting design revisions to project management systems – our plugins ensure your CAD data and business systems stay in sync.
From processing hundreds of drawings overnight to generating complete drawing sets from templates, our automation plugins eliminate the manual, repetitive work that slows your team down. We build intelligent automation that handles the tedious tasks while maintaining accuracy and consistency.
We design custom ribbons, dockable palettes, and interactive dialogs that match AutoCAD's look and feel while providing powerful interfaces for your specialized workflows. From parametric design configurators to project management dashboards, our WPF-based UIs make sophisticated automation tools easy for engineers to use.
Our development process follows four phases – from discovery through ongoing support – designed to de-risk the project early and deliver measurable ROI. Most plugins go from concept to production deployment in 8–14 weeks, depending on complexity and integration requirements. Here is how each phase works.
We start by deeply understanding your workflows, pain points, and requirements:
Deliverable: Comprehensive requirements document, technical specification, UI mockups, and development roadmap with milestones.
Before full development, we build a working prototype to validate the approach:
Deliverable: Working proof-of-concept plugin that demonstrates key capabilities and validates technical feasibility. This de-risks the full development phase.
With validated requirements and proven concept, we build the production-ready plugin:
Deliverable: Production-ready plugin with installer, documentation, and training – ready for enterprise deployment across your organization.
After deployment, we provide ongoing support and enhancement:
Support options: We offer flexible support plans – from ad-hoc support to dedicated development resources for continuous plugin evolution.
Typical AutoCAD plugin projects range from $20,000 to $80,000 depending on scope and complexity. A focused geometry analyzer or data export tool with a standard UI sits at the lower end. Plugins that involve bi-directional ERP integration, complex combinatorial optimization logic, or multi-system workflows with custom dashboards sit at the higher end.
Every project starts with a paid Discovery phase ($3,000–$5,000) that produces a detailed scope, architecture, and fixed-price estimate for the full build – so you know the exact investment before committing.
For context: our POSforAFS formwork plugin delivered a 70% reduction in calculation costs. At an average engineering rate of $100/hour, plugins in this category typically pay for themselves within the first 2–4 projects.
We don't generate code with AI tools and hope it compiles. Our team works at the ObjectARX and .NET API level – where geometry kernels, drawing databases, and CAD-specific data structures require deep platform knowledge that generic developers don't have.
Our POSforAFS plugin cut formwork costs by 70%. Our CAD-to-SAP integration reduced BoM errors from 15% to under 2% and saved $120K annually. Our 3D Model Review Tool cut review time by 50% and manual errors by 80% on a gas processing facility.
Manufacturer software (DOKA, PERI) uses generic panel libraries. Standard connectors can't handle project-specific SAP mapping rules. AutoCAD's native data extraction is a data dump, not a report. We build what those tools cannot.
Fixed-price development after a paid Discovery phase. PoC before full build commitment. Every project scoped around measurable ROI – cost reduction, time saved, errors eliminated.
InStandart’s work complied with the end client’s criteria, and the project management was great. The team fully met the client’s requirements with items delivered on time. InStandart was professional, provided excellent service, and was outstandingly cooperative and precise throughout the project.

Most AutoCAD plugin projects fall in the $20,000–$80,000 range. A focused data extraction or calculation plugin with a standard WPF interface costs $20,000–$35,000. Plugins with bi-directional ERP/SAP integration, complex optimization algorithms, or multi-system dashboards range from $40,000–$80,000. Every engagement starts with a Discovery phase ($3,000–$5,000) that produces a fixed-price scope for the full build.
Typical timeline is 8–14 weeks from Discovery to production deployment. Discovery takes 1–2 weeks, the Proof of Concept takes 2–3 weeks, and the full build takes 4–8 weeks depending on scope. Simpler plugins (data export, basic geometry analysis) are faster. Plugins with ERP integration or complex optimization logic take longer.
We build plugins compatible with AutoCAD 2020 through the current release (2026), including vertical products like AutoCAD Plant 3D, AutoCAD Architecture, and AutoCAD MEP. We also handle version migration – updating legacy plugins built for older AutoCAD versions to work with current releases.
Yes. We built a bi-directional CAD-to-SAP integration platform for a midstream gas processing plant that reduced BoM data entry from ~4 hours to under 15 minutes per package and cut manual data errors from 15% to under 2%. We handle schema mapping between AutoCAD Plant 3D and SAP S/4HANA, automated validation pipelines, and real-time synchronization of Bills of Materials, equipment IDs, and asset metadata.
Yes. After deployment, we offer flexible support plans covering bug fixes, AutoCAD version compatibility updates, feature enhancements, performance optimization, new system integrations, and training for new team members. Most clients start with ad-hoc support and move to a dedicated development retainer as their plugin evolves.
Yes. We regularly extend or rebuild plugins that were started in-house or by other vendors. We audit the existing codebase, assess what can be retained versus rebuilt, and provide a clear plan for integrating new functionality with your existing AutoCAD environment – including custom toolbars, LISP routines, and .NET add-ins.
Compatibility is an architectural decision, not a patching exercise. Four practices make this work:
Abstraction layer. Business logic – geometry, calculations, validation rules – sits in version-independent modules. Only a thin adapter talks to the AutoCAD .NET API and Plant 3D’s PnP3dObjects. When Autodesk changes signatures, the adapter changes; the core doesn’t.
Lowest-version compile, multi-version validation. We build against the oldest AutoCAD release in your environment and run an automated regression suite against every release up to current. The same binary runs on AutoCAD 2022 through 2026 in our reference deployments.
Plant 3D-specific test matrix. Plant 3D’s project database schema and SDK shift more aggressively than core AutoCAD between releases. We maintain a dedicated harness validating extraction logic across Plant 3D 2020, 2022, 2024, and 2026 – catching schema drift before it reaches production. This is the architecture behind our CAD-SAP integration platform, which cut BoM error rates from 15% to under 2% in an Oil & Gas EPC deployment.
Contractual version SLA. Within 30–45 days of an Autodesk release, you get a compatibility-verified build. Not best-effort – contractual.
We build plugins as products, not project artifacts – which means we own the roadmap, the new feature work, and the long-term evolution of the tool. Your team focuses on engineering; we handle what changes in the plugin.
New requirements go through our product team. When your workflow evolves – new calculation rules, new export formats, new optimisation parameters, integration with another system — you submit the requirement, we scope it, deliver, and validate. This is faster and cheaper than maintaining .NET CAD expertise in-house, and it keeps a single team accountable for the product’s quality.
Configuration without code, where it makes sense. Routine adjustments – layer mappings, parameter defaults, report templates – are exposed as configuration so your engineers can change them directly without releases. POSforAFS was designed this way: formwork engineers tune optimisation parameters through the interface, not through code changes.
Support and upgrades are part of the engagement, not extras. Bug fixes, Autodesk-version updates, and compatibility patches are included under the support agreement. You’re not paying per-hour for things that should just work.
Long-term partnership, not a transaction. Every plugin we deliver has a named technical owner on our side for the lifetime of the product. The team that builds it is the team that evolves it – no handoff to a generic support queue, no losing context six months in.
