Arc Geometry
Hello,I would like to know how the point between vertices 1 &2, (0,0.212132,0), was obtained.I understand that it is with the ordinate of this point we calculate the coordinates of other vertices in the same circumference.Say I change the pipe dia, would this particular point remain the same, if not what is the expression to find the new value.Thanks in advance.

Alternative method for defining arcs
Is there any other, less tedious way of specifying an arc?Doing calculations for a point on the arc gets difficult at times, any alternative method for doing the same. Please help.

View vertices, blocks & Arcs
While it is understandable to not have a GUI for solver, isn't it very difficult to visualise and name vertices and blocks for meshing? Doesn't it warrant having some sort of 3D modeller tool for meshing?Are there any such opensource meshers available?

Vertices 0 & 17
Vertices 0 & 17 are not connected to any edge. Do we need those vertices here?

If 0 folder is not required, can we delete it? As we did in the previous tutorials
