Hmmmm...I am assuming that your models when merged in BIM360 Glue came out all mis-aligned
First is to check the Transform option for each has same set of co-ordinates for x,y,z etc / rotation/scale (If you are not sure how to do so...The Transform tools are used to align the individual models in a merged model. However, you can only use the Transform tools (coordinates, units) for one model at a time. The transformation applies only to the specific merged model. It is a one-time process. As the individual models of a merged model are updated, the transformations are applied.
- Open a merged model.
- In the BIM 360 toolbar, click Models.
- Select models. (Showing and hiding can help isolate models in the view.)
- In the Models module, select a reference model and click Transform.
- Set the coordinates of the reference model. (ie: enter X, Y, and Z coordinate values in Origin, Rotate, Scale and click Save.If you are aligning a model to another that has shared coordinates, simply copy and paste the coordinates.)
- If necessary, adjust the units of measure. To do so select the model and click Adjust units then Specify units
- click Ok.
PS: If you are using Revit 2015 or earlier you might need to update your BIM 360 Glue Add-in
