For example i have a tube with 2m diameter, if i select Vertexes of one end, and Scale them using Snapping \ Increment \ Absolute Grid Snap, I get 2.6m diameter on that end, but if I then scale them down, I get 2.08m, because the second scale was in % of 2.6m .

Snapping to grid get's messed up after scaling down vertexes

And another related issue, the 10% Scaling steps can't be changed by scaling the model Space (to achieve the steps that you need) .

Does anyone know how to perform such operations, such so the applied value would stay constant to world? (getting 2m after decreasing the diameter)

For example, programmatically the Absolute Grid Snap could be achieved by Snapping the closest to grid-step vertex, and range snap by auto/manually selecting a Vertex to translate it's world space modification to the scale space ("%") .

Use "push/pull" to give a distance in world units:

  • $\begingroup$ that its not affected by snapping?, yes $\endgroup$
