solidworks导出展开 c# ExportFlatPatternView方法

好像没有工程图的时候是没法用这个的

using System; using System.IO; using System.Runtime.InteropServices; using SolidWorks.Interop.sldworks; using SolidWorks.Interop.swconst; using System.Text; namespace tools { public class Exportdxf_flatview { static public string run(ModelDoc2 swModel, string thickness) { try { Console.OutputEncoding = Encoding.UTF8; // 后续逻辑不变... if (swModel == null || swModel.GetType() != (int)swDocumentTypes_e.swDocPART) { Console.WriteLine("错误：请打开一个 SolidWorks 零件文档 (.sldprt)。"); return ""; } string fullPath = swModel.GetPathName(); if (string.IsNullOrEmpty(fullPath)) { Console.WriteLine("错误：文档尚未保存，请先保存文件。"); return ""; } string? directory = Path.GetDirectoryName(fullPath); if (string.IsNullOrEmpty(directory)) { Console.WriteLine("错误：无法获取文件所在目录。"); return ""; } PartDoc swPart = (PartDoc)swModel; string outputfile = directory + "\\" + "下料" + "\\" + thickness; if (!Directory.Exists(outputfile)) { Directory.CreateDirectory(outputfile); } string dxfFileName = directory + "\\" + "下料" + "\\" + thickness + "\\" + Path.GetFileNameWithoutExtension(fullPath) + ".dwg"; var result=swPart.ExportFlatPatternView(dxfFileName,0); Console.WriteLine($"{result}！生成文档保存在：{dxfFileName}"); return dxfFileName; } catch (Exception ex) { Console.WriteLine($"发生错误: {ex.Message}"); Console.WriteLine("提示：请确保 SolidWorks 正在运行。"); } return ""; } } }
