How many times have you faced pure frustration when a BIM model went on loading perpetually? Or when opening a model or when processing a not-too-complicated task has left you waiting and staring at the screen at the expense of your precious time? This unnecessary and wasteful practice is too often commonplace in the office of anyone working in BIM principles and generally handling large Autodesk® Revit® models. Time is scarce and issues like this aren’t fully appreciated when they appear. They are often overlooked and mistaken for poor performance of a workstation.
To fully understand why this is happening and what can be done to improve model performance, we need to address the core of the issue: regular model maintenance and staff training to model, draw, and manage information to a set out standard. Firstly, we should understand that Revit is controlled by rules and relationships that form the basis of all work. If they aren’t followed accordingly, things can get very messy. To keep good health in check and avoid the mess as much as possible, there are tools and techniques at your disposal.
Inbuilt Revit Warning System
Warnings protect the integrity of the model and your data. Not all warnings affect performance; less serious ones are only there to inform the user. When confronted with 1000’s of warnings in a file, you need a strategy for resolving them timely. Best practice is to have a plan for how warnings will be taken on board and resolved by the team prior to labor-intensive modelling. Make priorities: performance, accuracy, documentation. Warnings typically peak before deadlines and some types of warnings are more common at different phases of the project. It is important to learn which warnings have a significant impact on model performance and need to be rectified.
Types of warning messages:
