This question is coming from one of our beloved Forum contributor and Mentor Alexander Rivilis

I am working with code which change color of Intersection Fill of Live Section. But although the color is changed, but this is not visible on the screen until I turn off and turn LIVESECTION:

I made slight changes to have this working

Note: To work this make sure LIVESECTION is not turned on

This code will change color of SECTION which converted to LIVESECTION

    public void SetSectionColor()
{
Document doc = Application.DocumentManager.MdiActiveDocument;
if (doc == null) return;
Editor ed = doc.Editor;
PromptEntityOptions peo =
new PromptEntityOptions("nSelect section: ");
peo.SetRejectMessage("nIt is not a section!");
peo.AddAllowedClass(typeof(Section), true);
PromptEntityResult per = ed.GetEntity(peo);
if (per.Status != PromptStatus.OK) return;
ObjectId idSecSets = ObjectId.Null;
using (Transaction tr =
doc.TransactionManager.StartOpenCloseTransaction())
{
Section sec =
tr.GetObject(per.ObjectId,
OpenMode.ForWrite) as Section;
sec.IsLiveSectionEnabled = true;
idSecSets = sec.Settings;
tr.Commit();
}
using (Transaction tr = doc.TransactionManager
.StartOpenCloseTransaction())
{
SectionSettings secset = tr.GetObject(idSecSets,
OpenMode.ForWrite) as SectionSettings;
secset.CurrentSectionType = SectionType.LiveSection;
Color clr = secset.Color(SectionType.LiveSection,
SectionGeometry.IntersectionFill);
ColorDialog cd = new ColorDialog
{
Color = clr
};
System.Windows.Forms.DialogResult dr = cd.ShowDialog();
if (dr != System.Windows.Forms.DialogResult.OK) return;
ed.WriteMessage("nSelected Color: " + cd.Color.ToString());
clr = cd.Color;
// Define that color we change
secset.SetColor(SectionType.LiveSection,
SectionGeometry.IntersectionFill, clr);
tr.Commit();
}
}
