G'day guys and gals,

I've been trying desperately to knit two surfaces together and had absolutely no success.

The error dialogue that I am getting is:-

Some faces in the result body are intersecting.

Please increase the knitting tolerance or retry with

"Verification on rebuild" turned off.

I have looked for intersecting areas and failed to notice any . I don't really know either whether there is a tool or function that could point any intersectioning faces out to me? All I want to do is knit the 'Firewall' (Red Arrow) to the main body (grey). For two days I've played around with this now, please help!

BTW, I don't want to turn VOR off........

Part is attached (SW2016 SP3)

Dave.
