I would like to know how softplan users query arch length in softplan for pie shaped lots to confirm the arch is correct. SoftPlan does not have arch length anywhere. I would hope that perimeter would give me this but it gives me the chord length. My issue is this. My legal plans do not give chord lengths always, sometimes provide deltas over many lots but over all the info in inconsistent. i need to be able to possibly extend an arch length a set distance in a specified direction or at least know how long the arch length is. All i can figure out is that splines have curved lengths. if I could figure out how to convert an arch to a spline or draw curved property lines as a spline that would at least be a clean way to confirm some numbers. I am currently tracing a curve with a spline in tiny increments to get a ballpark and it is horribly unprofessional. Please understand I get lots that have 3 curved property lines and one straight one so this is very important to me. Any help would be greatly appreciated.
