Unable to stitch or patch to make solid model. Why is it not working?

[Anonymous]

I've tried patching, stitching, and body filling the face that's open, but I am unable to close the model.  There's also one edge that highlights as 'open' when stitching, but i'm unable to patch or close that area to seal the model and make it solid.  Any thoughts or assistance would be greatly appreciated!

Hi @Anonymous ,

There were two surfaces, which was not allowing the body to stitch.

Deleting, redefining new surfaces  and stitching them will create a BRep body

Delete the middle surface: 

Delete the surface i have deleted and redefine a new surface:

Thank you.  I am able to delete the middle surface, delete the surface on the curvy face, then make a patch.  When i try to patch the rectangular face, though, it makes a patch but still shows as yellow rather than gray.  How did you make the new surface so that it joins with the rest of the body.  Yours is nicely solid!

Hi @Anonymous ,

I used Patch, The Yellow face will not stop you to stitch.

Grey coloured face is normal surface, Yellow surface is Reverse of normal face.

If in case if you want to change the normals, You can use "Reverse Normal" to flip the surface.
