I'm having difficulty straightening up this mesh in Blender - see here for the object:

enter image description here

I'm trying to follow the accepted answer here but I can't quite get all the vertices I need in order to straighten up the side. When I scale the object along the z index, in 3JS, the arc of the sides is exacerbated which is undesirable.

Any ideas on this?


An example of what happens when it gets scaled in 3JS

  • $\begingroup$ How exactly are you trying to straighten the object? All of the sides look flat when I opened the file. Are you trying to make the sides vertical? $\endgroup$ – Brenticus Dec 5 '17 at 17:27
  • $\begingroup$ @Brenticus I'm scaling the object in 3JS which causes it to distort which is why I need them to be absolutely vertical - see my edit for a what it looks like when scaled $\endgroup$ – Katana24 Dec 6 '17 at 10:54

Go into Edit mode. Click the vertex-select icon.

Press C for circle select.
Color in a couple vertices you want to align, then right-click.

Tap S to scale, then X, Y, or Z to limit along one axis.
You have to decide which axis is best.
Then press 0 to zero out that axis.

If you notice movement along the wrong axis, no worries,
just click X, Y, or Z at this point to affect another axis instead.
Tap Enter to finalize command.

Repeat with each pair of vertices 'till complete.
