cCurve

cCurve class aims to represent objects that will simplify handling geometrical data. Structure of cCurve mimics the feCurve structure that is used in FEMAP.

cCurve object has following properties:

• LONG ID - value that represents unique identification number of each curve
• Collection points - collection of cPoint objects which build the single curve.

Class is initialized with 0 value for ID and empty collection of points. To initialize the class objects with defined parameters follow example below:

Dim point As New cPoint
Dim curve As New cCurve

point.X = 5
point.Y = 7
point.Z = 14
point.ID = 1

curve.points.Add point
curve.ID = 9

Note

There is no upper/lower limit in number of cPoint objects that are stored in single cCurve object. Keep that in mind when forwarding the object further to FEM/CAD program as it may prompt an error if cCurve stores only one point, which mathematically is not a curve. Same relates to the upper limit, some programs have cap of 100 points per curve.

ExportPoints

ExportPoints this.ExportPoints
Description:
Method converts collection of cPoints of cCurve object that is calling the function and returns a two dimensional array VARIANT/DOUBLE of coordinates
Input:
cCurve object   cCurve objects only have access to this method, no other value is possible.
Output:
VARIANT object.ExportPoints function does not affect collection that is stored in the cCurve object. Return value has to be assigned to new VARIANT variable.
Return Code:
None
Remarks/Usage:
If cCurve object will be empty/will have no points stored, function will return value -1.
Example:
Dim curve As New cCurve Dim point As New cPoint Dim a_points As Variant a_points = curve.ExportPoints
