How to replace a hole with a node?

Use of the platform

I want to make a shell mesh of a flat surface with some holes.
I wanto to delete the holes, but keep nodes on their centers.
How can I do that?
Thank you

Hello, jcsaaver.

Here is how I did something alike to what you described:

  1. Press ‘centre de gravité’ and select hole by hole.
  2. Press ‘créer une face’, option ‘face & contour’ and make a filling in each hole.
  3. Now you can make a ‘Union’ and a ‘Partition’ over it with the vertices you created in 1)

Hope this helps.

Hélio.

Thanks @Maggoo, but I can not find the tools you mentioned.
Is it on shaper?

Hi,

in SHAPER, you can create the point at the centre of a hole using Construction> Point. Select last mode and select the contour of the hole.

Then Build> Vertex and select it to create a result object.

Then Features> Partition to add it to your shape. Or Build> Compound will do the same if there is no need to compute intersections.

Thank you @cbourcier. I did what you said, and though it works, I don’t know how to force the mesh to have a node in the vertex

once you create your vertex, you make a compound of your geometry and the vertex. this will add the extra node to the mesh.

The free nodes are not displayed in Shading mode (the default mode of mesh display). To see them, select the mesh, right-click in the 3D view> Numbering> Display nodes #.

Here is an example with Netgen 1D2D. We can see it creates also a node on the vertex not belong to the face.
