The exPreventOverlapMixt flag must always be used alongside either the exPreventOverlap or exChangeColorOnOverlap flag. When used with the exPreventOverlap flag, it ensures that links avoid overlapping with elements or obstacles, enabling their paths to include both rectangular and diagonal lines. When combined with the exChangeColorOnOverlap flag, overlapping links alternately adjust their width in addition to changing colors (sample 2)

I've noticed that recently, the elements get compacted once the Arrange method is performed. How can I prevent that
with Surface1 do
begin
with Elements do
begin
Add('Element A',Null,Null).ID := 'A';
Add('Element B',Null,Null).ID := 'B';
Add('Element C',Null,Null).ID := 'C';
Add('Element D',Null,Null).ID := 'D';
Add('Element E',Null,Null).ID := 'E';
Add('Element E',Null,Null).ID := 'F';
end;
with Links do
begin
Add(Surface1.Elements.Item['A'],Surface1.Elements.Item['B'],Null);
Add(Surface1.Elements.Item['A'],Surface1.Elements.Item['C'],Null);
Add(Surface1.Elements.Item['B'],Surface1.Elements.Item['D'],Null);
Add(Surface1.Elements.Item['B'],Surface1.Elements.Item['C'],Null);
Add(Surface1.Elements.Item['A'],Surface1.Elements.Item['E'],Null);
Add(Surface1.Elements.Item['A'],Surface1.Elements.Item['F'],Null);
end;
DefArrange[EXSURFACELib_TLB.exDefArrangeCompact] := OleVariant(False);
Arrange(Null);
end

Is it possible to add a link to show from bottom/down to top/up, rather that right to left (method-2)
// AddLink event - A new link has been added to the links collection.
procedure TForm1.Surface1AddLink(ASender: TObject; Link : ILink);
begin
with Surface1 do
