I have a similar issue here;
Solidworks 2018 SP 2.0
-Try to export DXF/DGW from model, and have Custom Map Solidworks to DXF/DWG enabled in save options.
- Mapping dialogue appears - and I am able to set up layers and entities to map - and I am able to save a Map file (which has no file extension?)
- DXF exports correctly as defined in mapping file.
-I go to repeat process again, (same part, different part, doesnt matter) this time with map file location filled out in DXF save options
-DXF does NOT export as per the mapping file.
What gives?? Solidworks, why so glitchy plz fix
I am also looking for the same answer and have been done explaining this to my VAR support guys.
In my case I have defined layers for different SW entities (same I have defined in my .DWG templates too).
So when I start exporting the SW drawing into DWG, I opt mapping using the map file I have saved with all these layers defined with respective entities. For example all my drawing dimensions are define in layer "DIM" with green color. After the export I open the DWG file and find all the dimensions in "DIM" layer with the predefined green color.
But some entities (e.g. machining symbols, balloons, arrows) appear as blocks, sometimes with different layers.
Also the text style changes into something undesirable. Is there any guideline on how to do this with perfection?
