Model Viewer is Unaware of model extents

In model viewer when I view dwgs, they usually show up as a tiny dot in the corner even though in Autocad the view extents command shows the proper project area.

Viewer:

Autocad with Zoom to extents:

The problem with this is that since the whole model has to fit into a tiny area of the 2d viewer window area, a lot of information gets stripped from the model and displays incorrectly when zoomed in.

 

This how it looks when zoomed to the project extents (it should look like the clip above from Autocad):

And when zoomed in even more to some small area of the project:

Vs Autocad:

All of these are xrefs in the drawing, no idea if that matters. It shouldn´t in my opinion.

 

Is there a plan to fix this in the viewer?

 

We cant use the 3d viewer in these cases either. Same file in 3d viewer:

I am telling people often that they can view files online they dont need the software installed, but then I dont know what to do when we land in situations like this.

It looks like there is something in the drawing in the location opposite the rest of the objects. Maybe it is is hidden somehow in AutoCAD and is getting exported.

 

While in AutoCAD with all layers and on and thawed, use Ctrl A to select everything in the model. Then deselect the area where everything that you want resides. You should have at least one thing still selected, hopefully in that area opposite the needed elements. Once you've identified them decide how you want to deal with them. Most likely delete but you need to determine if they are needed or not.

So I went over everything and it seems to be solved.

 

There were no objects that were out of the project area. But what happened was that there were some xrefs with realtive paths and some with absolute paths. These xrefs with absolute paths opened fine in autocad, but caused the online viewer to think there was something at 0,0 (which were the xrefs it wasnt able to load). The tricky part was that the only indication was that some xrefs didn´t load in the viewer which I initially thought was an issue coming from the scale.

 

Thank you.
