There are a couple of vase components many miles from the rest of the model. When I shift to Plan view and hit Zoom Extents it looks like a blank model space with the origin way up at the top.
Selecting and zooming in to the vase components shows this:
I’ve seen a few other models with fragmentation similar to this but not nearly as bad. After deleting those objects I get this with Zoom Extents.
I also fixed incorrect tag usage.
I’ll upload the file and give you the link as soon as it’s available.
BTW, do you really have to keep all that stuff surrounding the main space in your model? Seems to me that just creates clutter and causes the file to be larger than it needs to be.
