IGetSymArcs Method (IGtol)

Gets an array that defines all arcs in the symbol.

# .NET Syntax

Visual Basic (Declaration)
```Function IGetSymArcs( _
ByVal SymIdx As Short _
) As Double```
Visual Basic (Usage)
``````Dim instance As IGtol
Dim SymIdx As Short
Dim value As Double

value = instance.IGetSymArcs(SymIdx)``````
C#
```double IGetSymArcs(
short SymIdx
)```
C++/CLI
```double IGetSymArcs(
&   short SymIdx
) ```

#### Parameters

SymIdx
Indexed position of the symbol

#### Return Value

• in-process, unmanaged C++: Pointer to an array of doubles (see Remarks)
• VBA, VB.NET, C#, and C++/CLI: Not supported

# Remarks

Each arc in the symbol is defined by three points: center, arc start, and arc end.

Format of return information is the following array of doubles:

For the ith arc:

retval[9 * i + 0] = X-coordinate of center point

retval[9 * i + 1] = Y-coordinate of center point

retval[9 * i + 2] = Z-coordinate of center point

retval[9 * i + 3] = X-coordinate of arc start point

retval[9 * i + 4] = Y-coordinate of arc start point

retval[9 * i + 5] = Z-coordinate of arc start point

retval[9 * i + 6] = X-coordinate of arc end point

retval[9 * i + 7] = Y-coordinate of arc end point

retval[9 * i + 8] = Z-coordinate of arc end point
