Works great, thanks for the save as an earlier VW file.
Converting to NURBS then exporting as an STL significantly increases resolution.
Then using Hamma's Vectorscript improves the resolution on top of that.
For those that follow here, a bit more detailed process as follows;
This Vectorscript file is the STL conversion VW file. Open this in VW, copy and paste your VW design into this VW file, change the name in the "Navigation - Design Layer" box to the saved file name you desire, save, then click on line "STL Export UI Quality" in the "STL Export Ultra High Quality" script box, enter the desired resolution, hit return and the script will export as a STL with the resolution added to the saved name, to the same location of this VW file.
Thank you to The Hamma!
