Manual Calculations That Consume Senior Engineers
Complex or multi-stage work takes days to weeks of engineering time, and any design change means restarting. Worse, the result depends on which engineer ran it. (Level 4)
Here's What Our Tools Have Delivered on Real Projects
Four Levels of AutoCAD Automation
We automate four categories of AutoCAD work using the .NET API, ObjectARX, and Plant 3D SDK: custom plugin development for geometry-heavy calculations, data extraction from DWG files into structured Excel and ERP systems, batch processing across thousands of drawings, and bidirectional CAD-to-SAP integration. Compiled-code performance, not LISP scripting.
Level 1 – Scripts & LISP Routines
A fixed sequence of commands inside one drawing: layer renaming, title block data, purge and audit runs. Fits when: the rules never change between projects. Timeline: days to 2 weeks.
Level 2 – Custom Plugins
Automation with its own interface, parameters and reviewable output. Fits when: inputs vary by project and several engineers must get the same result. Timeline: 6-14 weeks.
AutoCAD Plugin DevelopmentLevel 3 – Data Extraction & Batch Processing
Getting information out of drawings into a form other teams can act on, across one file or a whole repository. Fits when: procurement or PM keeps asking engineers for numbers that already exist in the model. Timeline: 6-10 weeks.
CAD Data Export & ReportingLevel 4 – Optimisation & ERP Integration
Combinatorial problems, or data crossing a system boundary into SAP. Fits when: the manual procedure was already a compromise. Timeline: 3-6 months.
CAD-ERP Integration
Challenges with AutoCAD Workflows
Data Trapped Inside Drawings
Quantities, material codes and element counts exist in the geometry but reach procurement by hand. Every transfer is a chance to introduce an error. (Level 3)
Drawing Revisions Break Reports
The drawing gets revised, the spreadsheet does not. Downstream teams act on numbers that were correct last week. (Level 3)
No Standardization Across Engineers
The same task produces different output depending on who performed it – which makes review expensive and onboarding slow. (Level 2)
How Does AutoCAD Automation Work?
Step 1
Workflow assessment
We look at the task as it runs today: how often, how long, who performs it, what breaks. The output is a level assignment – which of the four approaches actually fits.
Step 2
Scope and acceptance criteria
Before anything is built, we agree what “working” means in measurable terms: what the tool takes in, what it produces, and the case that proves it. You are buying an outcome with a test attached, not a number of hours.
Step 3
Build against your environment
Your CAD standards, your existing customisations, your panel catalogues and naming conventions. Nothing you already use gets replaced.
Step 4
Handover
Documented source, handover sessions for your team, and support terms agreed with the engagement – including AutoCAD version compatibility as new releases ship.

Get Your Project RoadmapHow Much Does AutoCAD Automation Cost?
We price by scope and outcome, not by hours. What moves the figure:
Which level the task belongs to. A batch extraction tool and an optimisation engine are different orders of work, and the assessment call establishes which one you need before anything is quoted.
Your CAD environment. Existing customisations, non-standard templates, and legacy plugins that the new tool has to coexist with.
Integration surface. Whether the tool stays inside AutoCAD or has to speak to an ERP, a PDM system, or a client’s data standard.
Catalogue and rule complexity. Proprietary panel systems, discipline-specific validation rules, and client naming standards all have to be encoded and tested.
Delivery timelines are predictable and we publish them: scripts and LISP routines in days to two weeks, plugins in 6-14 weeks, extraction and batch tools in 6-10 weeks, optimisation engines and ERP integrations in 3-6 months. The investment figure is set after the technical call – a published range that ignores your catalogue and integration scope would be a number neither of us could stand behind.
Why Choose InStandart for AutoCAD Automation?
We tell you which level you need – including when it's Level 1.
The assessment comes before the proposal, and it sometimes ends with "you don't need us for this."
We work where AI code generation breaks.
Three reasons this domain resists it: CAD APIs have thin public documentation, so generated code compiles and then fails on the third production drawing. The engineering logic – your panel reuse rules, your ownership conventions – is not written down anywhere a model could have learned it. And geometric kernels need numerical stability built from years of edge cases, where code that drifts a millimetre per operation is worse than none.
We complement your existing tools.
If you run DOKA, PERI or MEVA software, we build what it doesn't cover. We are not asking you to replace anything.

Feedbacks From a Clients About a Completed AutoCAD Project
Excellent Service
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.
It was a real pleasure working with them
Firstly we were cautious about InStandart. We never heard about such company, nor we didn’t know if something like things that were promised, were possible. In the end InStandart proved itself. They were always consulting direction of the project. They made corrections, if something was wrong and incorporated every demand. Every two weeks they delivered a new version and by the end of the project it was even every week. And mainly they delivered what was promised. It was a real pleasure working with them.

Frequently Asked Questions
Ask Your Technical QuestionWhat can be automated in AutoCAD?
Anything repetitive and rule-based: drawing preparation and parametric generation, data extraction into Excel or databases, batch processing across drawing sets, engineering calculations inside the CAD environment, and data synchronisation with ERP systems. What cannot be reliably automated is judgement that varies case by case without a rule you can state.
Should I commission a plugin or a script?
If the task is a fixed command sequence inside one drawing and the rules never change, a script or LISP routine is enough – often written in-house. If it needs parameters, a review interface, or consistent results across several engineers, it needs a plugin.
How do I know which level of automation my task needs?
Three questions usually settle it. Does the task have inputs that change by project? Does someone outside engineering need the output? Does it cross into another system? One yes points to Level 2, two to Level 3, three to Level 4.
How long does AutoCAD automation take to deliver?
Scripts and LISP routines: days to two weeks. Custom plugins: 6–14 weeks. Data extraction and batch tools: 6-10 weeks. Optimisation engines and ERP integrations: 3-6 months.
Which AutoCAD APIs suit which kind of automation?
AutoLISP for lightweight fixed sequences. The .NET API in C# for plugins needing custom UI, ribbons and palettes. ObjectARX in C++ for performance-critical work requiring direct geometry kernel access. Plant 3D SDK for process and piping automation.
When is custom automation not worth it?
When the workflow is under review, when the task runs only a few times a year, or when an existing product already covers it. We say so at the assessment stage rather than after a proposal.
Can automation work with our existing AutoCAD customisations?
Yes, and this is usually the first thing the assessment examines. Legacy plugins, custom templates and in-house LISP libraries define the environment the new tool has to live in – and occasionally the cheapest answer is extending what you already have.
What does the first call actually cover?
Bring one workflow your engineers repeat. We establish which level it belongs to, what building it would involve, and whether it’s worth building. Within 48 hours you get that in writing, with a phased approach if it makes sense.
