AnchorPoint in the center of node leads to strange line-routing (Read 6355 times)

	Hi there I have a node which has an anchorpoint in it's center (50/50). Now if I connect two other nodes to this nodes, the line-routing is not straight to the center, but always goes around above node and then goes from there to the center (see attachment 1). Now I would like that it behaves like you see in attachment 2, the lines should go directly to the center. At the moment, the user would always have to modify the lines in order to achieve that. Is it possible to set this behaviour somewhere in the properties? Thanks in advance

	Hi, Apparently when link's end point is inside a node the router selects the shortest path that will take it outside the node first, and only after that checks for directions. When at the center there are four such paths but the router always selects the first one found at the top. At this time you could use an AnchorPattern with points at middles of four sides instead of one in the node's center: Code new AnchorPattern(new[] { // percents of width / height new AnchorPoint(50, 0), new AnchorPoint(100, 50), new AnchorPoint(50, 100), new AnchorPoint(0, 50) }, "MiddlePoints"); then routing with RoutingOptions.Anchoring = Reassign should attach the link to the correct side. I hope that helps, Stoyan

	Hi Stoyan this was the solution I had also in mind. The problem is, that we have a model behind this diagram which is according to a standard. This standard does not know different anchor points for a node, so it would be really hard, as our tool must be able to read standard conform files (where then this information is missing...) Isn't there another possibility? Thanks anyway for your fast feedback

	Hi, You shouldn't have to specify anchor point values yourself if that's what troubles you. Depending on what features you are using and whether you let users move nodes, try setting properties such as link.Dynamic=true, RoutingOptions.Anchoring=Reassign, or calling the ReassignAnchorPoints methods of links to move link end points towards the connected nodes. I hope that helps, Stoyan

	Hi Stoyan ok thanks, I will try this out as soon as I find time. I will give you feedback either if it worked or not. Thank you for your help!

	Hi I know this thread is quite old, but I wanted to ask if in the newest version the same problem still exists and if so if it is planned to be fixed, so that we could work only with one anchor point in the center and the routing still would work properly? Thanks for the info.

	Hi, Try this build, our developer extended the EvaluateFarPoints option a bit to handle that case - https://mindfusion.eu/_beta/wpfdiag352.zip Code diagram.RoutingOptions.EvaluateFarPoints = true; diagram.RoutingOptions.Anchoring = Anchoring.Reassign; // EvaluateFarPoints doesn't work with Keep diagram.LinkRouter = new GridRouter(); Regards, Slavcho

	Hi Slavcho thanks for this very quick response. Cool this sounds promising, I will try it as soon as I can. However one issue there might be is that for most of our Nodes we want no automatic reassigning, just for a certain type. Right now we use the solution with the 4 nodes and manually trigger the reassignment of the anchor point for the impacted links upon moving of nodes...Would this as well be possible somehow? Thanks for your help

	We'll extend it to work with the Keep option too then. Regards, Slavcho
