Some Models Not Showing In Ortho Views

[Anonymous]

Hey there just seeing if anyone can help with my problem?

I'm currently putting together an orthographic view with models that are located in the Project Manager. Everything seems to show and come in fine except for these two files i am having trouble with. I don't know why they won't show. These Models are in the Project Manager aswell as all the others but still nothing. All I know is one model has been created in Solidworks and converted to a dwg while the other model was taken from another project from a few years back. Also both files are very small like 1mb each.

Please anyone? anything would be appreciated

Thanks

One thing you might try is opening up these files and saving them as the current DWG version.  If the one drawing is an older Plant drawing, it may be added to the project (migrated) as another option for getting it to display in the ortho view.

are those x-ref-ed? did you check those files in 3d model selection when creating orthos?
