Accurate Boolean Operations help/query/bug

[SteveR_UK]

Hi,

I wonder if someone can shed some light on this.

I have attached file simply contains two  slightly overlapping donuts shapes which have been duplicated.

Step1 
With the top (red) donuts selected I perform a Intersect operation. 

 

 

The result on screen  appears correct as expected, however if I select this top layer (the result of Intersect operation) and the next layer down (grey donut layer) and perform a  Boolean subtract it appears I don't get a accurate clean cut.

Any help would be appreciated

Hi @SteveR_UK,

This is a known issue with subtract leaving bits behind.  It already logged with the Dev team and i've updated the log with a link back to this thread, so we can update you when it's resolved
