Model data are exclusively composed of blocks and sub-sets composing these blocks:
Add a new vertex in the document:
ve = doc.addVertex(x, y, z)
Get the number of vertices of the document:
sum_v = doc.countVertex()
Get a vertex of the document:
v = doc.getVertex(i)
Get the coordinates of a vertex:
x = ve.getX()
y = ve.getY()
z = ve.getZ()
Set the coordinates of a vertex:
ve.setX(x1)
ve.setY(y1)
ve.setZ(z1)
Find a vertex in the document (with a tolerance):
ve = doc.findVertex(x, y, z)
GUI command: Vertex
