Extending Surface


Hi

I’m been asked to extend pointed face by 6mm.

I wasn’t the one who created the file and I’m not too sure how I’m gonna extend by 6mm from there… Currently its closed polysurfaces but when i explore them it turns out to be few surfaces.

Any Ideas?
Thank you.

Can you post the file?
The surrounding surfaces of that top face look rather messy, so I suspect you’ll need to reconstruct those.
