Method DeleteUnusedTables

Namespace

DeleteUnusedTables(vdLayers, vdBlocks, vdDimstyles, vdLineTypes, vdTextstyles, vdImages, vdHatchPatterns)

This method should be used in order to delete multiple primaries objects. It is much faster than setting Deleted = true to the primary directly.

Examples

Delete all layers with their entities that start with name VULCAN

vdDocument doc = vdFramedControl.BaseControl.ActiveDocument;
doc.UndoHistory.StoreUndoGroup(true);
vdLayers layers = new vdLayers();
foreach (vdLayer layer in doc.Layers)
{
    if (!layer.Name.StartsWith("VULCAN")) continue;
    foreach (vdFigure fig in layer.GetReferenceObjects()) fig.Deleted = true;
    layers.AddItem(layer);
}
doc.DeleteUnusedTables(layers, null, null, null, null, null, null);
doc.UndoHistory.StoreUndoGroup(false);
