.Net開發中20-22版本的浩辰cad，添加紙張后，通過代碼的方式無法立即獲取到，只有cad重啟后才可以獲取,手動從打印頁面操作pc3添加和代碼方式都不行,并且在打印頁面可以手動選擇正常打印,但通過API無法獲取到最新圖紙庫,只有重啟之后才可以獲取到,而23及其以上版本只需要在獲取圖紙庫之前執行

PlotSettingsValidator plotSettingsValidator = PlotSettingsValidator.Current;

plotSettingsValidator.RefreshLists(new PlotSettings(true));

即可獲取到最新紙張。以下是我讀取打印機紙張內容的操作,medlist為獲取到的圖紙庫信息,請注意我已經確保了打印機可以被識別和讀取，重點是當我在當前添加紙張后，若不重啟cad則無法獲取最新的圖紙庫，盡管在打印頁面已經顯示出來了。

var doc = Gcad_ApplicationServices.Application.DocumentManager.MdiActiveDocument;
var db = doc.Database;
PlotSettingsValidator psv = PlotSettingsValidator.Current;
PlotSettings ps = null;
using (var trans = db.TransactionManager.StartTransaction())
{
LayoutManager layoutManager = LayoutManager.Current;
var acLayout = (trans.GetObject(layoutManager.GetLayoutId(layoutManager.CurrentLayout), OpenMode.ForWrite) as Layout);
PlotSettings plotSettings = new PlotSettings(acLayout.ModelType);
plotSettings.CopyFrom(acLayout);
plotSettings.PlotSettingsName = "Gcad_Eplot_PageSetupTest";
plotSettings.AddToPlotSettingsDictionary(db);
trans.AddNewlyCreatedDBObject(plotSettings, true);
ps = plotSettings;


psv.SetPlotConfigurationName(
ps,
GetDeviceName() + ".pc3",
null
);
psv.RefreshLists(ps);

trans.Commit();
}

StringCollection medlist = psv.GetCanonicalMediaNameList(ps);
