I am trying to create a curve which passes through specific point locations.
In Rhino, the command is _curvethroughPt.
What is the Python equivalent? I started out thinking it was rs.AddInterpCurve(points), but this treats the points as control points instead of actually passing through the points.
rs.AddInterpCurve
should pass the curve through your points. rs.AddCurve
will make a control point curve âŚ

Hi Bluekite,
That is exactly what rs.AddInterpCurve() python function does - creates the curve, the way âCurveThroughPtâ command does with âCurveType = Interpolatedâ option. The curve actually passes through initial points.
If you want the same result, as the âCurveThroughPtâ commandâs option: âCurveType = ControlPointâ, use the rs.AddCurve() function.
OK, I now see that rs.AddInterpCurve did actually pass the curve through my points. The confusion arose when I entered âPointsOnâ in Rhino to check the work. The Points which became visible were calculated control points, not the points I had entered as part of my script.
Thanks guys, for your help.
what is a better way of making my points visible as part of the Python script? this is what I have now:
points = (0,0,0),(20,10,0),(50,-10,0),(100,50,0),(200,0,0),(250,10,0)
rs.AddInterpCurve(points)
Which points? Those from your points
tuple?
If that is so, try this:
import rhinoscriptsyntax as rs
points = (0,0,0),(20,10,0),(50,-10,0),(100,50,0),(200,0,0),(250,10,0)
rs.AddInterpCurve(points)
pts_ids = rs.AddPoints(points)
rs.ObjectColor(pts_ids, [255,0,0])
Wonderful! thanks so much!
