how to Clone edges on primitive ?

[markmu]

hi my dear friends

 

In fact, I tried to imitation cinema 4d's Slide Tool >Clone edges

https://help.maxon.net/us/index.html#XSLIDETOOL-MDATA_MAINGROUP

Do you have a better idea?

 

I  use polyextrude node on a primitive,

 I want to merge point number 26 to primitive number 4,

and primitive 4 , it has five point, it becomes N-gon 

Should I use facet or fuse node?

Please check the attachmenthow to make a n gon.hipnchow to make a n gon.hipnchow to make a n gon.hipnc.

 

Thank you！

you could, but you would have a hole (the 18/9/26 triangle), and possibly problems downstream (for example, if you subdivide the geo later)

Even if the hole if zero area, the geometry will be dirty. You will have problems at rendering because there is a discontinuity between the normals on either side of the " edge " (just two edges which happen to be at the same place)

Primitives are made of vertices, and those vertices are shared, which makes the geometry connected.
