﻿Vector3d.IsTiny Method (Double)

# Vector3dAddLanguageSpecificTextSet("LST9E2AF313_0?cpp=::|nu=.");IsTiny Method (Double)

Determines whether a vector is very short.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
```public bool IsTiny(
double tolerance
)```

#### Parameters

tolerance
Type: SystemDouble
A nonzero value used as the coordinate zero tolerance. .

#### Return Value

Type: Boolean
(Math.Abs(X) <= tiny_tol) AND (Math.Abs(Y) <= tiny_tol) AND (Math.Abs(Z) <= tiny_tol).
Examples
```using System;

partial class Examples
{
public static Rhino.Commands.Result AddLine(Rhino.RhinoDoc doc)
{
Rhino.Input.Custom.GetPoint gp = new Rhino.Input.Custom.GetPoint();
gp.SetCommandPrompt("Start of line");
gp.Get();
if (gp.CommandResult() != Rhino.Commands.Result.Success)
return gp.CommandResult();

Rhino.Geometry.Point3d pt_start = gp.Point();

gp.SetCommandPrompt("End of line");
gp.SetBasePoint(pt_start, false);
gp.DrawLineFromPoint(pt_start, true);

return Rhino.Commands.Result.Success;
}
return Rhino.Commands.Result.Failure;
