Application Version: Applied All Revit
Issue:
The challenge is to determine whether linking or grouping in a Revit project is more suitable.
Causes:
Linking multiple models can significantly impact performance, while grouping can be challenging to set up and use effectively
Solution:
The ongoing debate between using Revit links and groups doesn't yield a clear answer. Instead, consider the advantages and disadvantages of each approach to decide what works best for your project.
Benefits of using Links:
- Separate Model Management: Linking allows for independent model management. You can easily move and adjust linked models without impacting the main project model. Users responsible for updating the link can work independently.
- Mild Learning Curve: The linking method is relatively easy to learn and doesn't require complex configurations.
- Simplicity in Manipulation: Moving, copying, mirroring, and rotating links is generally more straightforward compared to groups.
Disadvantages of using Links:
- Performance Impact: Linking too many models can lead to significant performance degradation, making it challenging to work in the project model.
<When you have multiple unit links copied for layout, the model starts to lose its graphic fidelity and degrade its performance quickly. >
- Editing Constraints: To edit a linked model, you need to unload it, which can be inconvenient for instant modifications.
- Limited Instance Parameters: Linked models have restricted use of instance parameters for families.
Benefits of using Group:
- Consistent Performance: Grouping doesn't usually impact performance, regardless of the number of groups in the project. Unlike links, groups don't need to be unloaded for editing.
<Compared to the example with links, there's no significant graphic fidelity impact even with twice the number of units.>
- Ease of Modification: Groups can be modified within the project environment, allowing for live updates without additional loading steps.
- Flexible Use of Instance Parameters: Groups support easier use of instance parameters for families.
Disadvantages of using Group:
- Steep Learning Curve: Proper setup and use of groups require a deeper understanding of Revit. Additionally, setting aside space for group management can lead to extra element counts in schedules if phase is not properly applied.
< Users need to understand how to work with Worksets, Phases, and Groups to properly apply group mechanics. >
- Complex Manipulations: Moving, copying, mirroring, and rotating groups can be more challenging, depending on the group structure.
Best way to determine which method team should use for the project:
To decide which method to use for a project, consider your team's Revit skill level. For multi-family and hotel projects, using groups may be ideal, but this requires careful management, casework family restructuring, and a solid understanding of Revit's phasing. Though using the unit-as-link method is easier, model performance may decline during the later stages of design development in mid-to-large projects.
By weighing these pros and cons, you can determine the best approach for your Revit project.
