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 ");
