Thanx, what i did was just create a cylinder in the VM, selected 3 faces down all around and scaled with scale tool. thats right i lost some edges after welding and it created edges. see green on right. what am i doing wrong
If you had 20 edges around the top, to start with and 16 when you were done…that’s where the ‘extras’ on the rest of the item came from…those 4 ‘missing’ edges from around the top.
I’m not quite sure what you are doing wrong, but it looks like you aren’t scaling things evenly. If you were, then it wouldn’t collapse the edges and all the vertices would still be equidistant. When you weld (in most modellers) it collapses two ‘close’ vertices into one…and there’s usually a preset distance for this, but it doesn’t really matter. If you scale something, unevenly, then some vertices will be closer than others and may then fall within the distance of what is counted as ‘weldable vertices’.
You are going to need to find a way to scale what you want so it scales evenly…
Here’s how I would build it in Blender, to give you some idea of what I’m talking about (making sure you keep the edge count the same).
I’d start with a circle and extrude it up several times for the ‘body’ of the item. The, for the ‘neck’, with the edge loop still selected, I’d scale it down, before the next extrusion. Then I’d extrude up a couple of more times. Then I’d close off the top and bottom (a couple of different ways to do that). But the key is, making sure that when you scale, for the neck, you do so evenly.
