In the Lines/Curves, Create Curve menu I would really like to see Spiral Curve Spiral added back into this menu. When designing rail alignments I like to design with polylines prior to going to an alignment. Meeting tangent requirements for reversing curves with a very flat deflection angles is my main reason I would like to have this back.
Also while I am on the subject of spirals. If Spirals are in an alignment it will not export using Trimble Link export alignment.
Thank you.
