Rule Refinement: My First Ruleset | Solibri Tutorials 

It sounds like you're trying to create an MEP (Mechanical, Electrical, Plumbing) system in Solibri and encountering an issue with the available Property Set Names. Property Set Names in Solibri are used to define the properties and attributes of elements within a BIM model. It's possible that the specific Property Set Name you're looking for, such as "Mechanical," might not be available by default, or it might have a different name. Here are a few steps you can try to address the issue: 1. **Check Property Set Name Variations:** Sometimes, Property Set Names might not match exactly with what you expect. Check if there are variations of the name you're looking for, such as "PSet_Mechanical," "MEP_Properties," or similar. Different software and standards might use different naming conventions. 2. **Custom Property Sets:** If the default Property Set Names don't include the one you need, you might consider creating a custom Property Set with the desired attributes and properties for your MEP system. 3. **Update Solibri Definitions:** Solibri has a set of rule files and property definitions that it uses to analyze BIM models. These definitions might need to be updated or expanded to include the specific Property Set Name you're looking for. Check if there are updates available for Solibri's rule files and definitions. 4. **Consult Solibri Documentation or Support:** Solibri's official documentation or support resources can provide guidance on creating MEP systems and dealing with property sets. You can refer to their documentation or contact their support team for assistance. 5. **Model Specific Issues:** Ensure that your BIM model is correctly set up with the appropriate elements and attributes for the MEP systems. Sometimes, if the model isn't structured correctly, it can lead to issues with property set recognition. If you're still having trouble after trying these steps, reaching out to Solibri's support team would likely be your best option. They can provide specific guidance based on your situation and help you troubleshoot the issue more effectively.
