I'm trying to model this vase on the left in this picture,

enter image description here

However, I'm still a beginner in Blender, and the furthest I could go is as depicted in the screenshot below:

enter image description here As you can see, the beginning was promising, but applying the subdivider made it horrible.

I started from a cube building up, and used Boolean difference to subtract the hole inside.

I'm not looking for a full solution, I just need guidelines like how should I start? a plane? a cube?

shall I start from low model and then apply a subdivider? or I should start as smooth as possible?

EDIT:

I took @Simon approach, I started with a cylinder, squashed it at the bottom, and unsquashed at the top, after the boolean with another perpendicular cylinder, things got ugly and I had to cut faces to make them Quads instead of NGON. This is the best I could do: enter image description here

EDIT2:

More progress, this time, to do the boolean, I extracted the edge from the original body, and extrude it to create the boolean operand, this is the result before Subdivider modifier. Do I have to clean the body manually? like moving vertices, merging them, cut some faces? or there is a faster way (considering I have to repeat the process on four sides (unless I have to use Mirror))?

enter image description here

EDIT 3

I fixed the model after the boolean, and the results are better, but still can't get it perfect:

Especially these areas: enter image description here

Edit 4:

I started over again, to follow @Simon instructions, the results? Amazing. Check it out: enter image description here

  • $\begingroup$ Hello :). You're on the right track. Your mesh has some large N-gons, but Subdivision works best with Quads. Once you repair the topology, it will work just fine. $\endgroup$ – Jachym Michal Apr 25 '20 at 9:39
  • $\begingroup$ That's great, I like the page you shared, it is helpful. Do you suggest that I break them down manually into quads? or there is an easier way? $\endgroup$ – Nour Apr 25 '20 at 10:14

    $\begingroup$ You are trying to chew too much. Instead of trying to make a custom thing without knowledge howto, make something following a tutorial step by step. Once you get enough experience shapes like these will be no problem. $\endgroup$ – Jaroslav Jerryno Novotny Apr 26 '20 at 4:31
  • $\begingroup$ @JaroslavJerrynoNovotny I like to chew outside my comfort zone :D, also if you noticed there is huge progress since I asked the question. I feel I'm a few hours from answering my own question, but thanks for the advice. $\endgroup$ – Nour Apr 26 '20 at 7:20

Ignore the hole to begin with. The main shape appears to be a squashed cylinder, so create the main outline by scaling down one axis, then loop cutting/extruding and scaling to create the overall shape. For the neck the shape is circular so un-squash this section. For the large hole, boolean a cylinder then clean up the geometry afterwards.

enter image description here enter image description here

Start with a 16 sided cylinder. I used a 100mm rad and 350mm height. Scale it down on one axis. Add loop cuts.

enter image description here

From bottom ring to top I scaled by about .7, .9, 1, .9, .6, .1, .1. Rounded the neck rings. Added supporting loops for the neck and base. Inset and extruded the neck downward. Delete end N-Gons then used Grid Fill to finish.

enter image description here

Add a 10 sided cylinder and shape accordingly. I am trying to end up with an easy way to create quads after the boolean so am looking to position the new cylinder vertices close to the vase vertices.

enter image description here

Snap and merge the resulting vertices together, creating quads. Tidy up the mesh. At this step I deleted half the model and mirrored the mesh to save time. Remember to flip normals on the mirror. Add supporting loops to the inner ring.

enter image description here

Subdivision result. This worked out better than my first attempt as there are now no triangles in the bottom corners of the hole.

    $\begingroup$ Did you just create the model that I've been trying to create for hours as a quick answer? You, sir, are amazing. Thanks a lot. $\endgroup$ – Nour Apr 25 '20 at 15:07

    $\begingroup$ Did you just put a detailed answer with steps and values that resulted in me being able to do the perfect version? I wish I can give you a reward. All I can give you is an upvote. I'm also marking this as answer. To see my latest version, check the end of the answer. $\endgroup$ – Nour Apr 26 '20 at 14:38

Your mesh has some large N-gons, but Subdivision works best with Quads.

You can either repair the topology, or start from scratch with quads.
Depends on you, both ways are fine.

Two ways of making quad topology. enter image description here

  • $\begingroup$ From that shape how do you "inflate" the rest? $\endgroup$ – susu Apr 25 '20 at 18:52
  • $\begingroup$ Hello :). I'd add thickness and then used proportional scaling to 'inflate' it. But Simon's answer is way more elegant. $\endgroup$ – Jachym Michal Apr 25 '20 at 18:58

    $\begingroup$ @JachymMichal as much as I liked your tip (it was really helpful) I had to go with Simon's answer as it really helped me to master this model. Thanks a lot, I wish I can give you more than one upvote. $\endgroup$ – Nour Apr 26 '20 at 14:39
