Services

Revit API Add-in Development (BIM Workflow Automation)

We develop Revit add-ins built for real-world workflows — reducing manual work, ensuring consistent model quality, and boosting productivity. Examples: rule-based QA/QC (naming, parameters, templates, views), automated creation of views, sheets, and schedules, quantity takeoff and BOQ export to Excel, family placement, replacement, and batch editing, error-checking view generation, and logging with rollback for safe operations.

Custom CAD API Tools for Streamlined 2D Drawing Production

We enhance the efficiency of 2D drafting, revision, drawing review, and standardization in CAD using custom API tools. Examples include: batch processing of layers, blocks, and attributes; automated compliance checks against in-house standards (notation rules, layer conventions, block specifications, etc.); output data formatting for drawing issuance; and automated report generation and data aggregation.

Extending & Integrating ACC (Autodesk Construction Cloud)

Built around ACC-based workflows, we provide extensions and companion tools that streamline information sharing from design through construction. Examples include: operational design of folder structures, access permissions, naming conventions, and approval workflows; integration between Revit data and ACC (attachments, version control, ID assignment); Excel/CSV/database connectivity; and master data management and data mapping.

Others (DX Support & BIM/CIM Implementation Consulting)

In addition to the services above, we also offer flexible support for a wide range of DX-related needs. For challenges that arise throughout the BIM/CIM implementation and utilization process — such as establishing standards and rules, data integration, standardization, training and adoption, and workflow improvement — we carefully assess your situation and propose the optimal solutions tailored to your needs. Feel free to consult with us.

Track Record of Partnerships

We have partnered directly with two general contractors and numerous specialty and subcontracting firms, supporting their workflow improvement and system development efforts.

Our key services and past achievements include the following:
● Development of custom Revit / CAD add-ins tailored to each client's unique workflows
● Standardization of CAD drawings in line with internal company standards
● Cleanup and error correction of CAD drawings exported from Revit
● Automation of repetitive Revit / CAD tasks in design and shop drawing workflows
● Custom app development for workflows on Autodesk Construction Cloud (ACC)
● Development of systems that streamline end-to-end project management and seamless data registration and retrieval in the cloud

Case Studies

Revit White-Line Face Alignment Tool

● A common challenge is that standard Revit families cannot accurately follow road gradients and curved surfaces, causing pavement markings—such as crosswalks, lane lines, and directional arrows—to appear distorted or unnatural.
● KOWA's tools allow markings to conform naturally to even the most complex road geometries, delivering higher visual quality while cutting down on family creation and adjustment work.
