Error during close surface
Error during close surface
(OP)
hello ,
I am getting non manifold error during close surface when i try to convert a complex surface to solid. Please help me on this. How to resolve the errors and warnings during close surface command ?Thanks in Advance.

RE: Error during close surface
Most likely you have a surface that does not completely enclose a volume or it is not limited by a planer curve (like the lateral of a cylinder without planar disks).
I would recommend using the Boundary feature from the Generative Shape Design workbench to highlight open patches in your surface that need to be closed.
Hope this helps,
Best of luck!

Thank you so much for your reply. Will try it and get back to you..

-Split primitive solid (e.g. block, etc) created in Part Design with Yours surface
-Thick surface
-Sewing surface
Of course You can close Your surface manually, if there is only single boundary, especially if it is 2-D curve, You can extract boundary, create FILL and then Join Surface+Fill

In your case sudhakar12345, there are two possibilities (which prevent a clean Close Surface):
- Some surfaces are not close enough to be able to close a singular volume by CATIA and in that case use the Join
feature with Distance Propagation (right click in the window of the Join and click Distance Propagation) after selecting a face. In this case set a tolerance (Merging distance) big enough to be able to close the surface. More about this feature can be found here.

- The other possibility is that you have bifurcating surfaces (like the letter Y) which will not permit closing...
A simple cylinder can be closed by the Close Surface because it can be closed by simple and planar surfaces automatically. CATIA can manage this...Best of luck!

ERROR : Some non manifold configurations are detected.they are not managed by join operator.Modify input bodies to suppress these non manifold configurations.

By the way how do you want me to create the boundary?

Also if you have healing capabilities, this will help solve your problem.
