There is only one closed CADLWPolyLine with arcs in the polylineArc.dwg file.
After cloning the polyline one time, arc lines are shifted a little.
When I clone the polyline several times, the arc lines are shifted more.
I used the DeepCloneObject() method from viewtopic.php?f=15&t=10437#p22351. (I only changed the return type from void to CADEntity)
Code: Select all
string dwgFile = "polylineArc.dwg";
CADImage cadImage = new CADImage();
cadImage = CADImage.CreateImageByExtension(dwgFile);
cadImage.LoadFromFile(dwgFile);
for (int i = 1; i < 30; i++)
{
CADLWPolyLine pl = (CADLWPolyLine)DeepCloneObject(cadImage, ConvSection.Entities, cadImage.Converter.Entities[0]);
pl.Vertexes.ForEach(en =>
{
(en as CADVertex).Point += new DPoint(300000 * i, 0, 0);
});
}
CADImport.Export.CADtoDWG.SaveAsDWG(cadImage, "plarc_29.dwg");
if (cadImage != null)
{
cadImage.ClearBuffer();
cadImage.Dispose();
cadImage = null;
GC.Collect();
}
DeepCloneObject()
Code: Select all
public static void CloneStyle(CADImage targetImage, ConvSection styleSection, CADEntity srcStyle)
{
if (srcStyle.EntName == "Standard")
{
if (srcStyle.GetType() == typeof(CADDimensionStyle))
{
CADDimensionStyle dimStyle = targetImage.Converter.DimensionStyleByName("Standard");
dimStyle.AssignEntity(srcStyle);
targetImage.Converter.Loads(dimStyle);
}
if (srcStyle.GetType() == typeof(CADStyle))
{
CADStyle style = targetImage.Converter.StyleByName("Standard");
style.AssignEntity(srcStyle);
targetImage.Converter.Loads(style);
}
}
else
{
DeepCloneObject(targetImage, styleSection, srcStyle);
}
}
public static CADEntity DeepCloneObject(CADImage targetImage, ConvSection targetSection, CADEntity source)
{
CADEntity clone = (CADEntity)Activator.CreateInstance(source.GetType());
clone.AssignEntity(source);
clone.ExtendedData.AddRange(source.ExtendedData);
targetImage.Converter.Loads(clone);
if (targetSection == ConvSection.Entities)
{
// Clone the source entity layer
DeepCloneObject(targetImage, ConvSection.Layers, source.Layer);
// Add the cloned entity onto a layout
targetImage.CurrentLayout.AddEntity(clone);
targetImage.GetExtents();
if (source.EntType == EntityType.Dimension)
{
CADDimension sourceDim = source as CADDimension;
// Clone the dimension block
DeepCloneObject(targetImage, ConvSection.Blocks, sourceDim.Block);
// Clone the dimension style
CloneStyle(targetImage, ConvSection.DimStyles, sourceDim.Style);
// Clone the dimension text style
CloneStyle(targetImage, ConvSection.Styles, sourceDim.TextStyle);
}
if ((source.EntType == EntityType.Text) || (source.EntType == EntityType.MText))
// Clone the text style
CloneStyle(targetImage, ConvSection.Styles, (source as CADText).Style);
}
else
{
if (source.GetType() == typeof(CADBlock))
{
// Assign the source block name to the clone
(clone as CADBlock).Name = (source as CADBlock).Name;
}
// Add the cloned non-visible object to a corresponding section of the target drawing
targetImage.Converter.GetSection(targetSection).AddEntity(clone);
}
return clone;
}
The polyline cloned one time.
