在PPT中，形状是非常重要的元素。3-D形状，立体多元，给人耳目一新的感觉。在幻灯片中添加3-D效果形状，必然会为PPT的整体效果增色不少。为形状设置三维格式时，可设置棱台，轮廓线，表面效果等。

本篇文章，旨在介绍在使用免费的Spire.Presentation，独立创建Powerpoint文档，添加形状，并设置三维效果。感兴趣的朋友，可以从[E-iceblue官网下载][E-iceblue]免费的Spire.Presentation。下载完成后，请将bin文件夹的.dll添加作为引用。友情提示：使用Spire.Presentation可独立创建powerpoint文档。

需要添加的命名空间：

using Spire.Presentation;
    using Spire.Presentation.Drawing;
    using System.Drawing;

**步骤详叙：**

**步骤一：**创建PPT文档。

Presentation presentation = new Presentation();

**步骤二：**添加形状，设置其位置，大小并填充颜色。

IAutoShape shape1 = presentation.Slides[0].Shapes.AppendShape(ShapeType.RightArrow, new RectangleF(150, 150, 150, 150));
    shape1.Fill.FillType = FillFormatType.Solid;
    shape1.Fill.SolidColor.KnownColor = KnownColors.RoyalBlue;

**步骤三：**为该形状设置三维效果。

ShapeThreeD Demo1 = shape1.ThreeD.ShapeThreeD;
    //设置表面效果
    Demo1.PresetMaterial = PresetMaterialType.Matte;
    //设置棱台类型，高度和宽度
    Demo1.TopBevel.PresetType = BevelPresetType.ArtDeco;
    Demo1.TopBevel.Height = 4;
    Demo1.TopBevel.Width = 12;
    //设置轮廓线类型，颜色，宽度
    Demo1.BevelColorMode = BevelColorType.Contour;
    Demo1.ContourColor.KnownColor = KnownColors.LightBlue;
    Demo1.ContourWidth = 3.5;

**步骤四：**再添加一个形状作为对照。

IAutoShape shape2 = presentation.Slides[0].Shapes.AppendShape(ShapeType.Pentagon, new RectangleF(400, 150, 150, 150));
    shape2.Fill.FillType = FillFormatType.Solid;
    shape2.Fill.SolidColor.KnownColor = KnownColors.LawnGreen;
    ShapeThreeD Demo2 = shape2.ThreeD.ShapeThreeD;
    Demo2.PresetMaterial = PresetMaterialType.SoftEdge;
    Demo2.TopBevel.PresetType = BevelPresetType.SoftRound;
    Demo2.TopBevel.Height = 12;
    Demo2.TopBevel.Width = 12;
    Demo2.BevelColorMode = BevelColorType.Contour;
    Demo2.ContourColor.KnownColor = KnownColors.LawnGreen;
    Demo2.ContourWidth = 5;

**步骤五：**保存文档为.pptx，启动查看效果。

presentation.SaveToFile("result.pptx", FileFormat.Pptx2010);
    System.Diagnostics.Process.Start("result.pptx");
