VectorDraw Developer Framework(VDF)是一個用於應用程序可視化的圖形引擎庫。有了VDF提供的功能,您可以輕鬆地創建、編輯、管理、輸出、輸入和打印2D和3D圖形文件。該庫還支持許多矢量和柵格輸入和輸出格式,包括本地PDF和SVG導出。
問:
隨附的圖形在VDraw和AutoCAD中看起來不同。有什麼方法可以過濾VdfCAD / VDraw中不需要的AecDb…-vdInserts?
答:
您可以嘗試使用AfterOpen事件來過濾此類塊/實體,並將其隱藏在凍結層中。例如嘗試代碼:
private void button5_Click(object sender, EventArgs e) { doc = vdFramedControl1.BaseControl.ActiveDocument; doc.OnAfterOpenDocument += new vdDocument.AfterOpenDocument(doc_OnAfterOpenDocument); doc.Open(@"MyDrawing.dwg"); } void doc_OnAfterOpenDocument(object sender) { vdLayer aeclay = doc.Layers.FindName("AECLAYER"); // THE layer where these are going to be hidden if (aeclay == null) { aeclay = new vdLayer(doc, "AECLAYER"); doc.Layers.AddItem(aeclay); } aeclay.Frozen = true; // set to frozen foreach (vdBlock item in doc.Blocks) // check all blocks { bool is_aec = false; foreach (vdFigure fig in item.Entities) { vdText txt = fig as vdText; if (txt != null) {// Filter is to contain the text AecDb.. and has less than 3 items / // You can alter this filter as you like. if (txt.TextString.ToUpper().Contains("AECDB") && item.Entities.Count<3) {// that contain the string AecDB... is_aec = true; break; } } } if (is_aec) { foreach (vdFigure fig in item.Entities) { fig.Layer = aeclay; // hide the entities of this block } is_aec = false; } } }
