Version (10.2.13) of our Curve and Grade utilities is here.
This version includes a new tool named ‘Dissolve Horizontal Curves’. It attempts to dissolve/merge adjacent non-class ‘A’ polygons created in the ‘Construct Horizontal Curves’. Class ‘A’ curves can be absorbed into a dissolve if the length is less than the distance specified in the dialog. Curves having opposite signed radii are also not allowed to dissolve.
