在调用cad的.net api打印pdf文件效率很低
大神们，你们好，我在调用cad的.net api生成pdf文档的时候，效率很低具体需求
比如在一张图纸上我指定了4个区域，我想把这4个区域打印成4个pdf文件，如文件1，文件2，文件3，和文件4，生成这4个文件一般需要6分钟左右，效率很低下，测试的cad图纸不复杂，请问大神我问题出在哪，
下面贴上我的打印代码
Document acDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

//Layout acLayout = (Layout)acTrans.GetObject(acLayoutMgr.GetLayoutId(acLayoutMgr.CurrentLayout), OpenMode.ForWrite);
//获取当前布局的打印信息
PlotInfo acPlInfo = new PlotInfo()
{
Layout = acLayout.ObjectId
};
PlotSettings acPlSet = new PlotSettings(acLayout.ModelType);
acPlSet.CopyFrom(acLayout);
//着色打印选项，设置按线框进行打印
acPlSet.ShadePlot = PlotSettingsShadePlotType.Wireframe;
PlotSettingsValidator acPlSetVdr = PlotSettingsValidator.Current;
//打印比例
//用户标准打印
acPlSetVdr.SetUseStandardScale(acPlSet, true);
acPlSetVdr.SetStdScaleType(acPlSet, StdScaleType.ScaleToFit);
//居中打印
acPlSetVdr.SetPlotCentered(acPlSet, true);
//调用GetPlotStyleSheetList之后才可以使用SetCurrentStyleSheet
System.Collections.Specialized.StringCollection sc = acPlSetVdr.GetPlotStyleSheetList();
//设置打印样式表
acPlSetVdr.SetCurrentStyleSheet(acPlSet, "测试打印样式1.ctb");

}
//设置是否使用打印样式
acPlSet.ShowPlotStyles = true;
//设置打印区域
Extents3d extents3d = frame.Extent;
//单位是米时
double h = double.Parse(entityscale) * 6;
double x = extents3d.MinPoint.X + unit * 2;
double y = extents3d.MaxPoint.Y + h + unit;
if (unit == 1)
{
x = extents3d.MinPoint.X + unit * 1;

acPlInfoVdr.Validate(acPlInfo);
while (PlotFactory.ProcessPlotState != Autodesk.AutoCAD.PlottingServices.ProcessPlotState.NotPlotting)
continue;
PlotEngine acPlEng = PlotFactory.CreatePublishEngine();
#region BackUpCode

acPlProgDlg.Dispose();
acPlProgDlg.Destroy();
}
while (PlotFactory.ProcessPlotState != Autodesk.AutoCAD.PlottingServices.ProcessPlotState.NotPlotting)
continue;
//MessageBox.Show("打印完成！");
在while循环中，等待的时间最久，似乎一直在等cad的打印机工作状态重置，另外，能不能把这4页生成到1个pdf文件里面呢，这样是否能够对效率做一些优化？
求大神指导，谢谢了！

} 大神们，你们在哪，求解答，谢谢啦！ 4页生成一个文件的话 你可以考虑换个pdf打印机

4页生成一个文件的话 你可以考虑换个pdf打印机
我记得有个pdffac..(工厂?)
PlotFactory么？
4页生不生成一个文件不是最重要的，我现在的问题是效率的问题
我用上面那个代码总共要花数分钟（取决于数量和图的负责度，比较简单的基本上都要上分钟了）
我的需求是把一个Extend2d范围内（即图框范围）内的东西打印到pdf图纸上
求大神指点，谢谢 本帖最后由 ps122hb 于 2016-3-7 08:23 编辑

打印机 pdfFactory
你是在模型空间还是图纸空间打印？我的理解你好像在模型空间，但程序里应该是图纸空间，你再看看

我是在图纸空间上打印的吧，取的是图纸上的坐标，然后按照区域来打印
pdffactory是必须要单独安装的吧
这样给客户相对来说不是特别方便 我今天试着写打印也和你一样的情况，非常慢，如果是直接用CAD的打印则很快 /// <summary>
