When it comes to planning and executing large-scale AV installations, precision and efficiency are non-negotiable. These projects involve hundreds of components, multiple teams, and complex systems that must work in harmony. That is why selecting the right CAD software is more than a technical choice—it is a strategic decision that impacts timelines, budgets, and overall project success.

In this blog, we will explore why CAD software is essential for large-scale AV installations, the top features to look for, and which tools currently lead the pack.

Why CAD Software Matters in Large AV Projects

Large-scale AV projects, such as multi-floor enterprise systems, stadium installations, or campus-wide video distribution networks, demand a high degree of coordination. CAD software enables designers and engineers to create accurate, detailed, and scalable drawings that form the foundation for installation, procurement, and future maintenance.

Without effective CAD tools, AV integrators risk miscommunication between teams, incomplete documentation, and costly delays. With the right software, however, every cable, rack, and speaker is accounted for before a single drill touches the wall.

What to Look for in CAD Software for AV Projects

When evaluating CAD tools for large installations, consider the following must-have features:

1. Layering and Organization

Layer management is vital when dealing with multiple systems—audio, video, control, power, and network. A good CAD platform should allow you to separate and organize elements for clear visibility and revisions.

2. Smart Symbol Libraries

Time is money on a large project. Software with built-in AV symbol libraries for speakers, displays, processors, and connectors can help standardize your drawings and reduce design time.

3. Scalability

You need a platform that can handle the scale of your project. Whether you are designing for one building or an entire campus, the software should remain responsive and accurate as the file size grows.

4. Integration with BOM and Documentation

Top-tier CAD tools link directly to your Bill of Materials and system documentation, allowing you to generate accurate purchase lists and reduce human error.

5. Collaboration Features

In large AV projects, engineers, architects, and IT teams must all work together. Cloud-based sharing, commenting, and version control features are essential.

Leading CAD Software Options for AV Professionals

Now that we have covered what to look for, here are some of the top CAD platforms trusted by AV professionals for large installations.

1. AutoCAD

AutoCAD has been the industry standard for decades. Its robust toolsets, customizability, and precision make it a strong option for AV design. It allows for detailed schematics, elevation drawings, and scalable plans. However, AutoCAD is a general-purpose tool. For AV-specific workflows, it often requires third-party add-ons or extensive customization.

Pros:

• Universally recognized format

• Excellent layering and scaling tools

• Integration with Revit and other BIM tools

Cons:

• Steep learning curve

• Not purpose-built for AV workflows

2. XTEN-AV

XTEN-AV is purpose-built for AV system design and stands out in large-scale projects thanks to its intelligent automation features. It includes a vast library of AV components, auto-generates wiring diagrams and rack elevations, and supports direct BOM creation.

This cloud-based platform allows teams to collaborate in real-time, making it ideal for distributed project teams. Its seamless integration of design and documentation reduces the risk of miscommunication and saves hours of manual effort.

Pros:

• Built for AV professionals

• Cloud-based real-time collaboration

• Automated drawing and BOM generation

• Excellent for large and repeatable systems

Cons:

• Requires internet connectivity

• May need training for teams used to legacy tools

3. D-Tools System Integrator (SI)

D-Tools SI offers a hybrid solution that includes system design, estimation, and project management. It can integrate with Visio and AutoCAD and includes detailed product libraries. While it is powerful for sales and quoting, it might not be as CAD-focused as XTEN-AV or AutoCAD.

Pros:

• Combines design and quoting in one tool

• Product library integration

• Project management features included

Cons:

• CAD capabilities depend on integration with other platforms

• Less focused on advanced drawing features

4. Revit with AV Plug-ins

Revit is increasingly used in BIM environments and is often preferred by architects and builders. For AV integrators working closely with construction teams, Revit’s 3D modeling and integration capabilities are valuable. However, it is more architectural than AV-specific unless paired with plugins.

Pros:

• Strong for BIM and construction coordination

• Advanced modeling and spatial planning

Cons:

• Not AV-specific without plugins

• Requires steep learning curve and processing power

Streamlining Workflows with the Right Tool

The right CAD software can completely transform your project workflow. XTEN-AV, for example, uses AI and automation to generate rack elevations, cable schedules, and signal flows automatically from a single design. This means that once your layout is ready, the documentation is too.

Time saved on drawing revisions or duplicate entry is time that can be spent on value-added tasks such as quality control and stakeholder communication. For large-scale projects, where delays are expensive, this efficiency is a significant advantage.

Final Thoughts

Large-scale AV installations are complex by nature, but the right CAD software can bring clarity and precision to every phase of the project. While legacy tools like AutoCAD remain reliable, platforms like XTEN-AV are redefining the workflow with automation, smart libraries, and collaborative cloud-based environments.

If you are designing systems that span multiple floors, buildings, or even cities, choosing purpose-built CAD tools will save time, reduce costs, and increase client satisfaction. As AV systems become more integrated and intelligent, so too must the tools we use to design them. Choosing the best CAD software for large-scale AV installations is not just about drawings—it is about driving project success from design to delivery.
