This is the twentieth, in a series of forty-nine curve file translations. The file, Geometry.Curve.NormalAtPoint.ds#20 is from the DesignScript Editor (DSE) Sample files.
After copying the script from the DSE, open DSS and paste it into the canvas. The initial translation contains the essential elements as shown below.
Make sure the pasted script is commented out so that it isn’t running as well as the translation. (otherwise a crash maybe)
Satisfied that node definitions are suitably defined, initial the Code to Node operation.
Doesn’t look like any further editing is needed. The Geometry graphic that is generated is shown below.
The files for this translation can be downloaded from the links below.
Thanks for looking.
