I have DraftSight 2019 x64 SP3.  
With my former version (2017), I was able to simply copy and paste a sketch from DraftSite to SolidWorks 2017. 
With the new 2019 Draftsite, I cannot make the copy paste function work for transferring a sketch anymore. 
It looks like the copy and paste are processing, but then zooming to see All results in a blank sketch. It will not transfer a sketch.  
Anyone know what the problem may be?
