Hi @jvpantin2,
The 'Pick New Host' command in Revit can be tricky, especially when you need to maintain the exact location of hosted elements after rehosting. Here are a few steps and tips that might help you retain the positioning and properties as closely as possible:
1. Use “Pick New Host” Carefully and Re-Align if Necessary:
When you select 'Pick New Host,' Revit might shift the element slightly if the new host geometry isn’t perfectly aligned with the original. To minimize movement, try selecting the new host element closest to the original position. Once rehosted, you may need to manually adjust any slight offsets.
2. Align and Lock to Reference Points Before Rehosting:
Before using 'Pick New Host,' consider adding reference planes or points to mark the exact location of your openings in the original host. After rehosting, you can use these reference points to align the opening and lock it to the new host, helping maintain its exact position and orientation.
3. Manual Adjustments for Lost Properties:
Unfortunately, properties like schedule level, elevation, and dimensions may not carry over automatically. Once the openings are rehosted, check each opening’s properties and manually reassign any missing data.
4. For Large Changes, Consider Copying Elements to Preserve Properties:
If there are extensive changes, copying and pasting elements to the same place within the new structural model may help retain location data more consistently, though this may not work in every situation.
Important Note: It’s generally a good idea to avoid using face-based families for openings if you anticipate frequent structural changes, as they tend to lose association more easily. If feasible, you might consider switching to hosted families that are less prone to detachment.
Let me know if this helps or if there’s anything else you’d like to explore!
