二.搭建一个Taskpane的SolidWorks插件
SolidWorks插件-将SolidWorks文件转换为gltf格式
虽然可以在另存为选项中扩展gltf功能，但为了在SolidWorks界面上显而易见，我选择了添加一个TaskPane界面。
2.新建一个带TaskPane的SolidWork插件
使用SolidWors自带SwCSharpAddin模板建立一个SolidWorks插件，关于如何找到这个模板可以在看我的另一篇文章。
2.1 新建一个名未DuSwToglTF的插件
2.2 去掉和按钮有关的代码
2.3 添加一个名为Convert.xaml的WPF用户控件.注意添加关于WPF的类库引用
System.xaml;WindowsBase;WindowsFormsIntegration;PresentationCore;PresentionFramework;
#region UI Methods
private void AddTaskPanel()
//DuSwToglTF.ConvertPanel.PreloadDlls();
ITaskpaneView pTaskPanView;
pTaskPanView = iSwApp.CreateTaskpaneView2((ConvertPanel.RootPath+"\\"+ "gltf.bmp"), "将Solidworks文件转换为glTF");
if (TaskPanelControl == null)
SwAddin.TaskPanelControl = new ConvertPanel(SwApp);
eleHost.Child = TaskPanelControl;
pTaskPanView.DisplayWindowFromHandlex64(eleHost.Handle.ToInt64());
catch (Exception ex)
SwApp.SendMsgToUser(ex.ToString());
#endregion
这段代码首先定义了一个TaskpaneView对象，然后通过ISldworks创建了一个TaskpaneView对象。紧接着实例化了一个WPF的用户控件，
此处使用的一个ElementHost来作为WPF界面的容器。此方面的介绍可以查看Winform与WPF的互操作性。最后调用DisplayWindowFromHandlex64方法显示了这个WPF控件，ToInt64()方法传递了一个指针给SolidWorks以便SolidWorks显示。
2.4 在ConnectToSW方法中调用AddTaskPanel()
public bool ConnectToSW(object ThisSW, int cookie)
iSwApp = (ISldWorks)ThisSW;
addinID = cookie;
//Setup callbacks
iSwApp.SetAddinCallbackInfo(0, this, addinID);
#region 添加Taskpane
AddTaskPanel();
#endregion
#region Setup the Event Handlers
SwEventPtr = (SolidWorks.Interop.sldworks.SldWorks)iSwApp;
openDocs = new Hashtable();
AttachEventHandlers();
#endregion
return true;
3.使用WPF做一个转换界面
接下来我们需要设计一下UI来实现我们的功能
3.1 安装必要nuget库
MVVMLight来实现MVVM模式
HandyControl 来美化UI
使用HandyControl注意在xaml文件中引用命名空间
xmlns:hc="https://handyorg.github.io/handycontrol"
并添加资源字典
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/SkinDefault.xaml"/>
<ResourceDictionary Source="pack://application:,,,/HandyControl;component/Themes/Theme.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
3.2 添加类 ConvertPanelViewModel.cs
namespace DuSwToglTF
public class ConvertPanelViewModel:GalaSoft.MvvmLight.ViewModelBase
3.3 设计界面--完整的xaml文件如下
<UserControl x:Class="DuSwToglTF.ConvertPanel"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

3.4将相应属性绑定到viewmodel上
详细的代码可以去GitHub查看
3.5 关于实时获取当前打开的文档，以便自动填写文件路径和名字。
为了在打开零件或者装配体时自动填写文件名和当前打开的文件路径，我们需要监听切换文档的事件。
在SwAddin.cs类的OnDocChange()方法中设置文档名字和路径
public int OnDocChange()
TaskPanelControl.viewmodel.SetModelDoc();
return 0;
3.6 实现ConvertPanelViewModel中的SaveClick()方法
/// <summary>
/// 保存按钮执行的动作
/// </summary>
private void SaveClick()
List<string> files = null;
Controller.Convertor.ErrorType errors = Controller.Convertor.ErrorType.NoErros;
IsInProgress = true;
if (!System.IO.Directory.Exists(FilePath))
swApp.SendMsgToUser("当前路径不存在：" + FilePath);
return;
if (FilePath.Contains("-") || FileName.Contains("-"))
swApp.SendMsgToUser("-为非法字符，路径或者文件民包含-字符，请修改路径或者文件名后重新保存");
return;
//会堵塞UI；TODO:异步方式实现转换
var model = Controller.Convertor.DuConvertor.ConvertToglTFModel(swModel, out errors);
if (model != null)
files = Controller.Convertor.DuConvertor.SaveAs(model, FilePath, FileName);
swApp.SendMsgToUser("保存完成");
if (files != null && IsOpenFile && files.Count >= 3)
System.Diagnostics.Process.Start( files[2]);
if (IsOpenFolder)
System.Diagnostics.Process.Start("explorer.exe", FilePath);
IsInProgress = false;
catch (Exception ex)
MessageBox.Show(ex.ToString());
// System.Diagnostics.Process.Start("ExpLore", "C:\\window");
*下面将介绍对SolidWorks模型处理和保存。
var model = Controller.Convertor.DuConvertor.ConvertToglTFModel(swModel, out errors);
