I’m running into an issue when creating materials for generic model families. I don’t yet know if the behavior is similar for other categories, but when I am in both the project and family environments with the element unpinned I cannot align the surface patterns. The entire geometry moves. I can get this to work with direct shape but then none of the surface patterns appear to be mapped correctly which means I have to manually align for hundreds of instances depending on the scenario. It appears as if the pattern is being mapped from the center of each surface, which is fine, but I would like to be able to align the patterns manually when needed or map from the corner of a surface and not the center. Is that at least possible from the grasshopper side?
The first solution is what typically works – align manually by selecting the pattern linework. When creating families in Revit this is how I typically adjust when needed. However, I cannot use this method for some reason when creating a family using RiR. Why is this the case? Do families made via RiR not recognize patterns that can be manually adjusted? Again, the entire geometry moves not just the pattern. Is the direct shape method the only solution that lets you use both of these pattern manipulation options?
Yes. When I attempt to edit from within the family environment it moves the entire geometry. This doesn’t happen in the family editor with families that I make natively within Revit. When I use RiR to create a family, then try to edit the pattern within the family editor, the whole geometry moves even with everything unpinned. I am selecting the pattern line too.
Could you provide an example of how to control these upon creation or confirm that it is possible using native nodes? This seems like a mundane issue but it is causing a huge bottleneck for us since we tend to show patterns on our elevations frequently and we need the geometry to live in the Revit environment (while still designing in Rhino).
Thank you so much for working on this problem for us.
Another issue that may be related is that our Revit BIM360 files are extremely slow when we have direct shapes or families loaded into them that were created in RiR. Is this a common issue or something that may be on our end?
I just uploaded a new 7z file. Thank you for looking at this for us.
Other files that I have tested were all local projects and not BIM360 hosted. They were more complex surfaces with many small perforations. I still get warnings for some of the geometry shown below, but the model is much faster and is a local project.
