Hi friend! I sent a Revit model to Speckle’s web browser, but found that it appears separated, I don’t know why this happens. There is still a problem, the climbing ladder and bollard should be independent family members, I don’t know why they are recognized as the same RevitInstance in Speckle together with the concrete pier (the concrete member floating to the distance in the screenshot), although the Host body of the climbing ladder and bollard is the concrete pier.
So they are actually different family instances, but the way we are handling hosting is by sending the hosted instances on the elements property of the host instance. To see which family is being used for the instance, you can inspect the definition property instead
