Visualize Points

💻 Rhino 5

🔼 Rhino Script

🛠️ Visual Basic

---

This Rhino Script presents a series of options for the visualization of points, relative to graphics output. Once points are selected the user can then select to overlay the points with either a circle curve, cross curve, coordinate anchor curve, spherical surface, or cubical polysurface. Once the output type is selected a series of orientation options are made available, either using the world coordinate plane, the camera plane, current construction plane, or a plane perpendicular to a user-specified point.
