Multisheet: The Future of Streamlined Engineering Collaboration


In today’s utilities and mining sectors, effective collaboration between creators of engineering drawings and field professionals is essential. Yet, the current state of information flow and collaboration in these sectors often falls short. When transferring information between drafting and maintenance teams, the default setting is often to opt for what is perceived to be the easiest approach. For multi-sheet files, this often means compromising technical files that were once rich with context and embedded attributes, by converting them into flat, stripped-out formats such as PDFs and PNGs.

In the absence of a multisheet-capable EDMS, splitting files may appear to ease the burden, however, the truth is that it merely transfers the cost and complexity (with interest) to your information management long-term not only sacrificing data but hindering drawing updates. In Engineering Drafting, a tangible example of this is the handover of native multisheet CAD files, which are either published to a PDF for ease of viewing or split out into multiple one-page CAD files, inadvertently sacrificing crucial data and context in the process. This short-term solution leads to challenges in maintaining live as-built versions and expensive back-drafting when the original file is missing.

At RedEye, we envision a better way forward. We are excited to introduce our latest release, Multisheet Upload, designed to preserve the native integrity of multisheet files, simplify sharing, and ensure the availability of the embedded data in the CAD file. Before we delve into the potential of this important feature, let's unpack the concept of multisheet CAD files and understand why they are a valuable engineering asset to your business.

Demystifying multisheet files

First things first, what is a multisheet file?

In the realm of engineering, jargon can sometimes be a stumbling block, so it’s vital that we clarify what we mean by a multisheet drawing file. Essentially, when we say Multisheet, we are referring to a technical or engineering drawing comprised of several layouts or sheets in a single file.

To break it down further, these files consist of two main components:

Multisheet modelspace (3)Model space
A boundless digital canvas where you can craft designs without any limitations. In this expansive workspace, known as the “model space”, you can sketch and model objects in both two and three dimensions, allowing you to give your creations the depth and dimension they need. Importantly, model space is calibrated to real-world scale, meaning you're not constrained by paper size or traditional drafting limitations. This ensures that what you design here can be directly translated into tangible, functional systems with exceptional accuracy.

This space is a drafter's best asset, offering a comprehensive view of the entire system and how its components interact with each other. This ensures both accuracy and the perfect fit for each part within the system. Whether you're designing a water pump, laying out an electrical circuit, or planning a building's HVAC system, the expansive and flexible nature of model space allows you to create detailed, accurate, and interactive representations of even the most intricate machinery.

Layout space
Once your design is finalized in the model space, it's ready to share with your stakeholders, and that’s where the "layout space" steps in.

In this space, you arrange how your design will appear on a physical sheet or a standard screen size, adding views, dimensions, and annotations to facilitate comprehension by others, making the information readable and communicating important concepts. It's where you fine-tune the scale, add titles, and polish your designs to make them easily digestible, so again with complex systems in mind where you need to work with single-line diagrams or electrical circuits, it’s a great way to have a single layout focussed on one direct piece in detail, without the distraction of everything around it. After all, great engineering drawings are a roadmap - they take the observer through the journey of how the system works. 

Now, let’s put this all together by illustrating it in a real-world scenario, and consider creating engineering drawings for a water pump:

  • In the Model space, you'd draft detailed drawings of each pump component and represent how the pump integrates into the larger system, easily controlling the scale of each in relation to the entire model.

  • In the Layout space, you'd generate individual sheets for each section, highlighting various components and maintenance procedures. You also scale the design to what you need to be presentation-ready, locking in the paper size and scaling to what is needed for the context of the layout.  

The competitive edge of native multisheet CAD files

With engineering projects becoming more intricate and expansive, the role of comprehensive documentation has soared in importance. Multisheet engineering drawings have risen to the occasion, proving to be an essential tool for cohesive and precise project management, thanks to their distinctive features such as:

  • Detailed documentation: Multisheet files encapsulate extensive details, an ideal choice for complex projects comprised of numerous components and specifications

  • Organized presentation: These files logically segment and organize information across different sheets, facilitating swift access to needed information without wading through cluttered, single-sheet drawings or burdening designers with creating team-specific sheet versions

  • Modular editing: Individual sheets within multisheet files can be edited or updated separately, allowing for easy and efficient incorporation of changes or updates, without risking unintended alterations to unrelated components

  • Enhanced collaboration: Multisheet drawings promote collaboration, enabling various teams to work on different sheets simultaneously, fostering a multidisciplinary approach to project development

  • Scalability: Multisheet drawings adapt seamlessly to project growth, allowing for the addition of extra sheets to encapsulate new details and components while preserving the original document's integrity and coherence

Navigating potential pitfalls

In many industries, the traditional approach has been to separate multisheet files into single-sheet files, particularly during activities such as project closeouts or sending transmittals and design packages. The point to note is that this often occurs because it's the only option available. However, this practice not only forfeits the inherent advantages of multisheet files but also complicates data management and collaboration by breaking the relationship between the layout “images”. 

By retaining the original structure, organizations create a centralized reference point, facilitating quick access to all related sheets and preventing data scattering. This not only saves substantial time when locating specific data but also fosters a seamless workflow that enhances project efficiency. Moreover, this approach guarantees that updates or changes are uniformly reflected across all relevant sheets within the same file, achieving a consistency level hard to match with separate single-sheet files.

Furthermore, it encourages smoother collaboration by allowing specific views for teams to work on as a part of the same project or asset. This choice avoids potential disruptions that could necessitate navigating through multiple files to coordinate efforts, and the cumbersome process of managing revisions across numerous single-sheet files.

In addition, multisheet files can integrate seamlessly with other project documents, providing a comprehensive project status view and sparing organizations from the extra efforts required to compile data from various sources. This synergy between documents streamlines project management, enhancing coherence and efficiency in operations.

By embracing the multisheet format, organizations can steer clear of the potential pitfalls associated with managing multiple, disjointed single-sheet files, paving the way for a streamlined, cohesive, and efficient approach to project management.
