Initializing the Z-axis value to zero

[Sing]

Hello

When checking if a box of polyline contains a point (DPoint) or rect (DRect) of CADLWPolyline or CADText, I use the 'Contains' method of CADLWPolyline or CADText Entities.

Code: Select all

if (dPolyline.Box.Contains(cadText.Box.Center))
{
	Console.WriteLine("Contained");
}

However, if the Z-axis values ​​are different, you cannot get the correct result.
I do not use Z-axis values. So I would like to initialize the z-axis values of all entities.

Is there a way for it?

Hello,

You may zero-initialize DRect.z1 and DRect.z2 for the bounding boxes you are checking and then call a DRect.Contains method on the modified DRect objects:

Code: Select all

public bool IsContains2D(DRect box1, DRect box2)
{
    box1.z1 = 0;
    box1.z2 = 0;
    box2.z1 = 0;
    box2.z2 = 0;
    return box1.Contains(box2);
}

thanks for the awesome information.
