When attaching a DXF as a background layer the text, labels and cells/blocks do not display correctly in the standalone platform.
The standalone platform's background layer display capabilities has minimal support for mtext (multi-line text) and cells. If it is mtext you will need to change it to either regular text or another type of text.
Open the DXF file in AutoCAD
Select all the text and blocks by right clicking in the drawing and using the "quick select" option from the pop up menu.
Set up your quick selection options to select all the mtext labels and blocks in your drawing file.
After everything is selected use the "X" (explode) command on the command line. This will convert all your "mtext" to regular "text" and break the blocks into pieces.
Save the file.
Add the file as a background layer.
Note: It is a good practice to purge unused or nested blocks and attributes in the drawing. Often when multiple users work on a drawing, there are lot of vestigial blocks, line styles, hatches etc. which may cause exaggeration of text or make the DXF appear generally skewed. Purging these unwanted objects/blocks cleans up the DXF to make it more suitable for viewing.
Additionally it is also better to check if your DXF is referencing external drawings (XREF) which are not available for import. These drawings should be detached to ensure you work on the intended DXF.
Select all the text the need to display in the background file
For text and cells, use the "drop element" tool. Make sure the drop element settings has the "Complex", "Text" and "Linestring/Shapes" checkboxes selected.
Attaching a DWG DXF or DGN as a background
Is it possible to change the font for text in DXF backgrounds and annotations?
After exporting a model to DXF, text appears shifted in the resulting DXF file
