Line and Arc from multiple PVI lines

Hi All,

Just wondering can we create a straight line and Arc with radius from mutiple PVI points using Dynamo. As seen in bellow image. Hope i am not missing any bestfit lines or Arc nodes.

The purpose of this exercise is to create a combination line and arc on a polyline with multiple PVI points. for example say survey points which are not exactly in same line will have small deviations but can be created in to a single line or ARC by joining the points.

Wishing all a happy holidays and thanks for support.

Have you tried one of these?

@jostein_olsen Thanks for reply …which package it is ? Can i use these nodes for AutoCAD ?

I think so, as stated above the nodes. two from springs package and one comes out of the box in Dynamo, meaning it is in the standard library

Thanks alot …will try using them and see if it works.

tried installing package …got bellow error. seems its not compatible with AutoCAD API.
