Inside Our BIM Toolbox: Dynamo and Add-ins That Make a Difference

In the fast-paced world of Building Information Modelling (BIM), efficiency isn’t a luxury; it’s a necessity. As BIM professionals, we frequently encounter repetitive, time-consuming tasks that can also lead to inconsistencies if handled manually. At Target AEC Global, we’ve embraced automation to tackle these challenges head-on. Two of our most powerful tools in this journey are Dynamo and Revit add-ins. 

1. Why Automation Matters in BIM 

BIM is inherently data-driven. Even seemingly simple tasks; such as tagging elements, placing dimensions, or exporting views, can become tedious and error-prone when done manually. That’s where automation comes in. It helps us: 

1.1 Minimize human error 

1.2 Ensure consistency across deliverables 

1.3 Improve turnaround time 

1.4 Enhance coordination and overall model quality 

2. Our Approach with Dynamo 

Dynamo, Revit’s visual programming environment, allows us to build custom scripts that streamline our day-to-day tasks. Here's how we put it to work: 

2.1. Bulk Data Input from Excel 

We use Dynamo to push large volumes of data into model elements via Excel. This significantly reduces time spent on manual data entry, especially in large-scale projects. 

2.2. Parameter Standardization 

Scripts help bulk-update shared or project parameters across families and elements to maintain data consistency. 

2.3. Room/Space Data Management 

Populating room names, numbers, finishes, or area values from Excel or predefined rules speeds up documentation workflows. 

2.4. Model Health Audits Scripts can quickly scan for warnings, unused views, or model elements with missing data, helping teams maintain model quality. 

2.5. Excel-Driven Element Placement We extract key data from PDFs into Excel and reference CAD files to accurately model elements like columns and footings using Dynamo. This ensures precise placement while saving time and reducing manual effort. 

These automations free up our team’s time, allowing them to focus more on coordination, clash detection, and model validation areas where human expertise adds the most value. 

3. Leveraging Revit Add-ins 

While Dynamo offers custom flexibility, Revit add-ins provide targeted automation for specific workflows. Here are a few we rely on: 

3.1. AGACAD Wood Framing Suite 

For timber-framed buildings, AGACAD’s Wood Framing suite is essential when working at LOD 300 or higher. It allows us to: 

3.1.1. Automate wall and floor panel generation based on predefined rules and templates 

3.1.2. Place studs, blocking, and Nailers with full control over spacing, alignment, and connections 

3.1.3. Handle complex joinery and end conditions with smart rules that reduce manual editing 

3.1.4. Generate shop drawings automatically, including tags, dimensions, schedules, and panel numbers 

3.1.5. Create CNC-ready outputs and detailed part lists, supporting downstream fabrication workflows 

This tool significantly reduces modelling time while increasing the accuracy and constructability of our framing models. 

3.2. pyRevit 

We use pyRevit, a powerful open-source extension, to run custom scripts and perform routine tasks more efficiently. It helps us: 

3.2.1. Quickly purge unused elements, line styles, and materials to keep the model clean 

3.2.2. Batch rename views, sheets, and families using smart naming conventions 

3.2.3. Access custom one-click tools for repetitive tasks like placing legends, toggling view settings, or exporting data 

3.2.4. Extend Revit’s capabilities through integrated Python scripting - directly accessible from the Revit interface 

pyRevit has become a core part of our day-to-day modeling operations, helping the team work faster and more accurately. 

3.3. DiRoots Tools 

The DiRoots suite includes several free, high-performance tools that streamline model management and documentation: 

3.3.1. Automate the creation of multiple sheets and placement of views 

3.3.2. Reorganize views and sheets in the project browser for better clarity 

3.3.3. Manage and clean up Revit families, including naming and version control 

3.3.4. Convert Excel tables into formatted Revit schedules or legends 

These tools help us reduce repetitive work, improve model organization, and maintain documentation consistency across projects. 

4. Real-World Results 

For a multi-occupancy building project, we combined the power of AGACAD Wood Framing and Dynamo to streamline our deliverables. 

Using AGACAD, we quickly generated panel layouts, applied precise numbering, annotations, and produced accurate fabrication drawings - significantly reducing modelling and detailing time. 

In the same project, we also deployed a custom Dynamo script to automate the transfer of panel weights and names into their respective assembly drawings. This replaced a manual, repetitive task and helped ensure consistency across all documentation. Together, these tools enabled us to deliver accurate, coordinated outputs with far greater efficiency. 

5. Moving Forward 

For us, automation isn’t about replacing people - it’s about enabling them to do more meaningful work. With the right tools and workflows in place, we continue to optimize our BIM processes and deliver projects with greater speed, precision, and confidence.
