您好我正在使用自定义应用程序来生成图纸并导出 dwg/png/pdf。Autocad 2016本地测试很好，但是上传活动时，服务器无法导出pdf。
db.SaveAs(dwgOut, DwgVersion.Current);
ed.Command("_pngout", pngOut, "");
ed.Command("_tilemode", "0");
ed.Command("_-export", "_pdf", "C", "N", pdfOut);`
它在核心引擎 v21 上。
AIO 报告：

这个 'Layout not foundCoreHeartBeat' 很奇怪……请问有什么提示吗？谢谢！
编辑：我也试过
ed.Command("_-export", "_pdf", "_C", "N", pdfOut);`
没运气。
我改为从模型空间打印 pdf
ed.Command("_pngout", pngOut, "");
ed.Command("_tilemode", "1");
ed.Command("_.ZOOM", "_E");
ed.Command("_-export", "_pdf", "d", "n", pdfOut);
是的，png 文件反映了布局，但我们在 pdf 中松散了布局。
我们认为问题可能出在我们在图纸空间中创建了一个新布局：
var id = LayoutManager.Current.CreateAndMakeLayoutCurrent("testLayout");
所以我们注释掉了创建布局部分，微调了导出的代码，并在本地测试成功：
ed.Command("_pngout", pngOut, "");
ed.Command("_tilemode", "0");
ed.Command("_-export", "_pdf", "c", "n", pdfOut);
同样，没有pdf文件。但这一次报告发生了变化：

现在是“当前操作中没有可打印的工作表”。
