Catia V5R20 joint problem

Hello

I'm having a problem when I'm making a joint with surfaces on Catia V5R20.

When I select all of my surfaces and create the joint and visualize it, there's a green line that appears right in the middle of the joint as you can see in the attached image (I've circled the problem line in red).

The problem is that I need this surface joint to be able to create a 3D model from this surface thanks to "close surface" in the Part fabric but it refuses to do so by telling me that the surface I selected is not correct and I get this error message: "Close Operator: an opening in the selected body cannot be closed by a planar face. Check all body openings for planarity"

And I checked but my surface is closed so I think the problem comes from this green line on one of the surfaces created and I would like to get rid of it. Does anyone have a solution?

Thank you in advance for your answers

Well I found in fact it was just a matter of increasing the "merging distance" which is a parameter when you create the joint.

Thank you anyway.

Hello.

You found the easy solution!!

For my part, I prefer to redo the surfaces or fill in if possible.

Modifying the connection accuracy of surface edges can cause problems on the topological operations you will perform on your solid but also during exchanges with other software (especially for machining).

It is better to avoid increasing above 0.01

Hello

Indeed it's the easy solution but for what I want to do with it, that's enough. 

I still keep your advice in mind. 

Thank you
