Hi all,

is there a option to get the nearest points to the boundary curve by radius toleranz ?

Hi,

Does this quick writeup help:

```
t = rs.CurveClosestPoint(curve_id,test_point)
curve_point = rs.EvaluateCurve(curve_id,t)
distance = rs.Distance(test_point,curve_point)
```

you first get the closest point to the curve and than get the distance and do something based on that distance

thanks for the help,

try at the moment

Rhino.Geometry.Curve.ClosestPoint()

and will check after that your option.

Hi,

If you are are working with Rhino Common already you should not user rhinoscriptcontext(rs)

rs.CurveClosestPoint() uses Rhino.Geometry.Curve.ClosestPoint().

As for Rhino.Geometry.Curve.ClosestPoint() can be passed a maximumDistance, functioning as your desired distance to boundary filter:

```
ClosestPoint(self: Curve, testPoint: Point3d, maximumDistance: float) -> (bool, float)
```

Thanks for reply,

tried this

import Rhino as rh

a = [rh.Geometry.Curve.ClosestPoint(x,i,20.0) for i in y]

and got this list , need to check if the bool pattern is the right points.

maybe there is a way to work with collection.pointlist instead of iterating throught list

Hi

How about:

```
import Rhino as rh
close_pts = []
for pt in y:
bln,t = rh.Geometry.Curve.ClosestPoint(x,pt,20.0)
if bln:
close_pts.append(pt)
a = close_pts
```
