If I wanted to add a hole into an object e.g. Create a tube

Is there an easy way to do that?

I haven't seen anything regarding negative space so far in Blender, and it would be really helpful for my project

Thanks in advance!

  • In edit mode you can switch to face select mode (control tab). Select faces and delete. You may need to created additional faces to delete.
  • Extrude or inset and remove faces
  • Use any mesh primitive with multiple faces and delete a face.
  • Add more faces (loop cut and slide) and delete a face to create hole.
  • Use a Boolean modifier with operation Delete to create additional geometry suitable to the final step to delete faces.
    In the image below we see from left to right
    • a plane
    • a plane with sphere placed to intersect the plane
    • goal mesh achieved with hole cut from Boolean modifier with [apply] clicked and user editing to delete extra vertices
    • plane selected with Boolean modifier present
    • plane with extra geometry created by Boolean modifier with [apply] clicked. Extra geometry will be deleted. N-gons may be present.

enter image description here

  • If rectangular outside with circular hole is desired use a torus or sphere or cylinder and use a shrink wrap to a rectangular outside. Below is an example of a torus with 3 vertex cross section.

enter image description here

  • The geometry created above may be more suited to some situations rather than a triangulated n-gon.
  • $\begingroup$ But if I wanted to do that to a 3D shape, surely there would be no "inside walls" to the hole? $\endgroup$

  • $\begingroup$ Boolean operates more on volumes. The extra faces can be deleted. One could say I really should have subtracted a sphere from a cube and then remove extra faces. I was prioritizing quick response over other concepts. I worked with what Blender has in front of me. If your provide additional requirements in your question we can try to address them. $\endgroup$ May 17, 2015 at 18:26
