Reply To: HELP problem when merging a cylinder with a cube “Industrial Environments with Eevee”
@sketchmore here is an alternative (not necessarily better!) way of doing this (I only show the bottom Face of the Cube here):
Where I use the W hotkey (Right Click Select), you might need to right click beside the Mesh to bring up the Specials Menu (Left Click Select) and LoopTools (you need to enable that Addon!) is also in the Specials Menu.
Like I said, not because it is better, but it is good to have different techniques available 😉
