I have two questions below. Thanks a lot.

1. How can I manually remove a pivot from a line?

2. I currently use the following code snippet to organize the shapes and lines in a Model object. I find that for cases with less 10 shapes, it organized them well. But for those with more than 10 shapes, I see some shapes get penetrated by a line.

a. I am wondering if I can improve my code to fix the problem. Or I should consider an upgrade.

b. I also notice that sometimes when a Model deserializes an xml string, some shapes in the recovered flow chart is hidden. I need to click on the Model once in order to make them visible. How can I avoid this problem?

Crainiate.ERM.Layouts.Layout layout = new Layout();

layout.NodesFromShapes(FlowChart1.Shapes);

layout.ChildNodesFromLines(FlowChart1.Lines);

layout.LayoutFlow(150, 150, OrientationEnum.Horizontal);

layout.ApplyLayout();

layout.RouteLines(FlowChart1.Lines, FlowChart1.Shapes, 200);.

1. You can use Line.Pivots.RemoveAt(index) where index is the position of the pivot in the collection
2 a) ERM Diagram 4 has a number of layout algorithms licensed from graph layout specialists. Its really worth the upgrade to be able to use these.
2 b) The latest version ERM 3.8.2292 may fix this, you can download it here

I used the latest version 3.8.2292 to fix the question 2b in my original post. However, it doesn't work. I am wondering if this problem has a workaround.

After a load you can try a model.Refresh() call to make sure all the elements are visible. If they are still not visible, then there may be a deserialization problem.

Thanks for your reply. The problem we have is that shapes and lines that are close to the edge of the model are not displayed properly. I mean they are rendered, but they are not visible. I need to click on the model in order to make them visible. So how can I fix this problem? Thanks a lot.

Btw, this is how we deserialize a model from an xml string.

this._flowChart.SuspendModel();

this._flowChart.SuspendLayout();

this._flowChart.SuspendDraw();

this._flowChart.Clear();

this._flowChart.DeSerialize(xmlFragment);

this._flowChart.ResumeDraw();

this._flowChart.ResumeLayout();

this._flowChart.ResumeModel();

this._flowChart.Refresh();

If you could send a small sample through to me via email or post some code or a screenshot that would be a great help,

Thanks
