Range Rebuild Curves

💻 Rhino 5

🔼 Rhino Script

🛠️ Visual Basic


Developed for optimizing curves for laser cutting files, this script allows the user to rebuild curves that fall within a certain point count range. The user is asked to select a series of curves and is then prompted to select a minimum and maximum point count as well as a point count for rebuilding if the curve falls within these parameters. Additionally, the ability to override the degree of curvature is included, if the value is zero the existing curvature is retained.
