If the DXF input data will not represent the expected layout in Viewplot,
the input data will contain un-supported (AutoCAD) DXF functionality.
Workaround:
Remove all spurious entities from the DXF drawing:
Load the DXF data in AutoCAD (Lite)
- Explode blocks and dimensions
- View => Zoom => Extents
- Edit => Select All (Ctrl+A)
- Modify => Explode or type "explode"
Explode:
Breaks a compound object into its component objects
A compound object comprises more than one AutoCAD object. For example, a block is a compound object.
- Purge drawing items

- File => Drawing Utilities => Purge.. & select Purge all
