I need to separate the middle edge between two poligons to not share the same edge by poligons, instead every poligon to have his own edge. I need this to make an inset operation of the two poligons. How I can achieve this?
Select the edge and press V to rip it
Or if its just two faces select each face individually and press Y to splt it. Repeat with other faces.
Or you could select the faces and Alt+E / extrude individual faces. Esc to cancel the extrude and you’ll be left with selected faces you can inset individually.
If you want to do the same with all faces you can apply an edge-splt modifier. You can join the faces again by removing doubles
Thank you. Is working.
