HI Guys, I’m new tom the forum so I thought I’d give it a go.
I’m facing this issue with various radii, that should meet eachother but without using ‘Patch’ I cannot seem to match them up. I know patch is a dodgy way of modeling and will not be of any use when used in other software.
HOw would you approach such a problem?
Hello - you can build simpler surfaces in general than the have here - when a hole to fill is four sided, a patch is almost never the right tool - use more basic ‘four-sided surfacing’ tools - it looks like you might have been able to make fillets throughout and simplified the transitions, but as is, for this particular surface, it may be that a NetworkSrf will make something OK there.

Thank you for your reply, Pascal!
Unfortunately, I have also tried the NetworkSrf, but no satisfying results.
Will keep trying… 
Anyone else any suggestions?
I’d fix your main surfaces first (especially the one facing the camera):
The shape seems to have a simple structure, based on straight extrusions, cutouts and fillets. Keep the structure as simple as possible as long as you can. Right now I see a mix of fillets, blends and patches.
Hi Gijs, Thanks. Yes, I realize I need to rebuild the entire part…
