How to use AlternateBasePoint in grip overrule?

[Anonymous]

Hi,

When I try use AlternateBasePoint in my class MyGripOverrule : GripOverrule {...,  

public override void GetGripPoints(...){
...
grips.Add(new MyGrip(){
    GripPoint = new Point3d(5,0,0),
    AlternateBasePoint = new Point3d(10,0,0),
}
...

I get always AlternateBasePoint =  Point3d(0,0,0)?   Why?

Thanks!

Just guessing - you have an extra comma after AlternateBasePoint = new Point3d(10,0,0),

I'll bet that C# interprets that as a missing parameter

Unfortunaly, comma doesn't influence on the result.

This is 2022, and 7 years later I still have the same problem, this is the code:

CustomGripData grip; //extends GripData

grip = new CustomGripData();
grip.AlternateBasePoint = new Point3d(5.0, 0.0, 0.0);

// at this point if you read grip.AlternateBasePoint it says {(2.8567367949313E-312,6.9519327022869E-310,1.11594791398818E-311)}
