I am having trouble getting my links to orient properly. In the attached picture, I'm trying to drag a link from the bottom of the rectangle on the left (outgoing) into the left side of the trapezoid (incoming). I want the outgoing link to be vertical, and the incoming link to be horizontal.

Here is the code that sets up the anchor pattern for the rectangle:

AnchorPattern = new AnchorPattern {
Points = new AnchorPointCollection(new AnchorPoint[] {
Point(50, 0, Orientation.Vertical, true, true),
Point(0, 50, Orientation.Horizontal, true, true),
Point(100, 50, Orientation.Horizontal, true, true),
Point(50, 100, Orientation.Vertical, true, true),
Point(0, 25, Orientation.Horizontal, true, false),
Point(0, 75, Orientation.Horizontal, true, false) })};

Here is the code that sets up the anchor pattern for the trapezoid:

AnchorPattern = new AnchorPattern {
Points = new AnchorPointCollection(new AnchorPoint[] {
Point(0, 25, Orientation.Horizontal, true, false),
Point(0, 50, Orientation.Horizontal, true, false),
Point(0, 75, Orientation.Horizontal, true, false),
Point(100, 50, Orientation.Horizontal, false, true) })};

Here are some related settings on my diagram:

diagram.LinkCrossings = LinkCrossings.Arcs;
diagram.LinkShape = LinkShape.Cascading;
diagram.LinkRouter = new GridRouter();
diagram.AllowSplitLinks = true;
diagram.Behavior = Behavior.DrawLinks;
Attachment 1 is what the link looks like when I try to drag from the 50,100 point on the rectangle (marked as Vertical) to the 0,50 point on the trapezoid (marked as Horizontal).

I want the link to start vertical and end horizontal, and the opposite is happening. I can then force the link to look like I want, but it takes some work. Any idea how I can make this behave correctly?

Ah...calling Route definitely helps.  It's not perfect, but it's definitely better.  See the attachment.  I suppose at this point I may be able to tweak the routing using the route cost options.  Thanks!
