Close Contour Merge 2 different vertex into 1 single vertex

Posted by Earl Fan at March 15. 2017

I have a problem when creating a surface with a contour that I believe is closed, since I draw every line with one's end attached to another's start. However, when I try to form a surface with the contour, it says 'there is no closed contour can be built from the given arguments". 

Then I try "Repair - Close Contour", but this operation merged two points into one, which is not what  I want.

 This is the result after  "Repair - Close Contour"

Hi

What is a length of the edge which disappears after Close Contour? Maybe it's less than 1e-7?

Hi,

Not a solution but: with cfdmsh you can get boundary vertexes using the GetBoundaryVertexes function. Like this you can see where is the hole in your original wire if there is one, and rebuild your wire more properly.

Else, maybe to avoid merging vertexes during contour closing you can first decrease the tolerance of your wire (Repair > Limit tolerance).

Hope this helps

Best regards

Thanks for reply!

The disappearing is 0.614 long, definitely not a small edge.

Maybe you try to create a surface from a set of lines? instead of creating a wire from lines and then the surface from the wire.

I have tried (Repair > Limit tolerance) but it's not helping, I'll try cfdmsh and thanks again!
