How to create a plane between vertices in 3dsmax?

Question

3D

Actually, I removed the vertices and as a result we got such a void. Return via Ctrl+Z is no longer an option) How to create a plane between the selected vertices or is it possible to somehow reduce them to one point to close the gap? The second half is mirrored by Instans, if that.

Answer 1

There are actually several options.
If you just close a hole in the object - the simplest option is the CapHoles modifier (but it does not always give a correct or good result).
If you want to manually control the polygons - Extrude the edges, place the vertices and then Weld them.

Answer 2

the model is made "half" for subsequent symmetry?
- you will make two opposite edges. bridge
- select border - cap.
- you get a closed hole.
-draw edges on the polygon trying to split into squares - cut or connect points.
