BoundingBoxXYZ.Transform

Public Property

The transform from the coordinate space of the box to the model coordinate space.

Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public Transform Transform { get; set; }

Property Value

Transform

Remarks

The transform must always be right-handed and orthonormal.

Example

private void RotateBoundingBox(View3D view3d)
{
    if (!view3d.IsSectionBoxActive)
    {
        TaskDialog.Show("Revit","The section box for View3D isn't active.");
        return;
    }
    BoundingBoxXYZ box = view3d.GetSectionBox();

    // Create a rotation transform to apply to the section box
    XYZ origin = new XYZ(0, 0, 0);
    XYZ axis = new XYZ(0, 0, 1);

    // Rotate 30 degrees
    Transform rotate = Transform.CreateRotationAtPoint(axis, Math.PI/6.0, origin);

    // Transform the View3D's section box with the rotation transform
    box.Transform = box.Transform.Multiply(rotate);

    // Set the section box back to the view (requires an open transaction)
    view3d.SetSectionBox(box);
