将新的 TEXT/MTEXT 实体添加到现有实体的右侧

如何将新的 TEXT/MTEXT 实体添加到现有实体的右侧

问题： 如何将新的 TEXT/MTEXT 实体添加到现有实体的右侧 (CADNET-8172)。

提示： 要做到这一点，创建一个 CadBaseEntity 对象，使用文本创建一个 CadMText 或 CadText，在新对象的 SoftOwner 字段中添加 cadImage.Layouts[“Model”].BlockTableRecordHandle 来自图纸，并将其添加到 cadImage.BlockEntities[" *MODEL_SPACE"] 块中，并将新对象添加到图纸实体中。

示例：

List<CadBaseEntity> entities = new List<CadBaseEntity>(cadImage.Entities);

List<CadBaseEntity> addedEntities = new List<CadBaseEntity>();

foreach (CadBaseEntity baseEntity in entities)
{
    if (baseEntity.TypeName != CadEntityTypeName.MTEXT)
    {
        continue;
    }
    else
    {
        CadMText mtext = (CadMText)baseEntity;
      
        if (mtext.FullClearText == "Known text")
        {
            CadMText design = CreateMTextToTheRight(mtext, "Design");
           // CadText design = CreateTextToTheRight(mtext, "Design");
            addedEntities.Add(design);
        }
    }
}

foreach (CadBaseEntity addedEntity in addedEntities)
{
    addedEntity.SoftOwner = cadImage.Layouts["Model"].BlockTableRecordHandle;
    cadImage.BlockEntities["*MODEL_SPACE"].AddEntity(addedEntity);
}

entities.AddRange(addedEntities);
cadImage.Entities = new List<CadBaseEntity>(entities).ToArray();

private static CadMText CreateMTextToTheRight(CadMText mtext, string value)
{
    CadMText newMText = new CadMText();
    newMText.Text = value;
    newMText.InitialTextHeight = mtext.InitialTextHeight;

    // mtext.HorizontalWidth may be useful too to get the width of the mtext
    newMText.InsertionPoint = new Cad3DPoint(mtext.InsertionPoint.X + mtext.ReferenceRectangleWidth, mtext.InsertionPoint.Y);
    newMText.LayerName = mtext.LayerName;
    return newMText;
}

private static CadText CreateTextToTheRight(CadMText mtext, string value)
{
    CadText text = new CadText();
    text.DefaultValue = value;
    text.TextHeight = mtext.InitialTextHeight;
    text.FirstAlignment = new Cad3DPoint(mtext.InsertionPoint.X + mtext.ReferenceRectangleWidth, mtext.InsertionPoint.Y - text.TextHeight);
    text.LayerName = mtext.LayerName;
    return text;
}
