Trim Method

Description

Deletes sections of geometry that intersect other objects.

Syntax

Visual Basic
Public Sub Trim( _ ByVal x As Double, _ ByVal y As Double, _ ByVal CutObj1 As Object, _ Optional ByVal CutObj2 As Variant _ )

Parameters

x: Specifies the x value of the direction point in which the trim is to take place.
y: Specifies the y value of the direction point in which the trim is to take place.
CutObj1: Specifies the first object that intersects this object. The intersection point of the object determines the trim point.
CutObj2: Specifies the second object that intersects this object. This intersection point of the object determines the second trim point.

Remarks

If one object is specified, it is trimmed from the intersection point of the objects in the direction of the point specified. If two objects are specified, the trim is in the section of the object specified by the direction point. For example, if the direction point is between the two input objects, the section of this object to be trimmed is between the points the two objects intersect this object. If the direction point is outside of the two input objects, the trim is from the intersection of the object closest to the direction point, in the opposite direction of the other input object intersection point. The resulting objects are put into the select set. In some cases, a single object can be trimmed and two objects are the result.
