使用块UI编辑器生成模板，将模板代码复制到新建的项目中，注意***.dlx的位置
执行代码
public class Line_Creating { //class members private static Session theSession = null; private static UI theUI = null; private string theDlxFileName; private NXOpen.Part workPart = null; //创建workPard private NXOpen.BlockStyler.BlockDialog theDialog; private NXOpen.BlockStyler.Group group0;// Block type: Group private NXOpen.BlockStyler.LineColorFontWidth lineColorFontWidth0;// Block type: LineColorFontWidth private NXOpen.BlockStyler.SpecifyPoint point0; // Block type: Specify Point 控件 private NXOpen.BlockStyler.SpecifyPoint point1; // Block type: Specify Point 控件 public Line_Creating() { try { theSession = Session.GetSession(); theUI = UI.GetUI(); theDlxFileName = "Line_Creating.dlx"; theDialog = theUI.CreateDialog(theDlxFileName); workPart=theSession.Parts.Work; //workPard为当前工作部件 } catch (Exception ex) { throw ex; } public int apply_cb() { int errorCode = 0; try { //---- Enter your callback code here NXOpen.Point3d start_point = point0.Point; //将point0的值return给start_point NXOpen.Point3d end_point = point1.Point; //将point1的值return给start_point NXOpen.Line line = workPart.Curves.CreateLine(start_point, end_point); //通过两点生成直线 int [] coloue_line =lineColorFontWidth0.GetProperties().GetIntegerVector("ColorValue"); //将颜色控件选择的颜色给存入数组中 line.Color = coloue_line[0]; workPart.ModelingViews.WorkView.Regenerate(); //重新生成当前视图，用于更新颜色 } catch (Exception ex) { //---- Enter your exception handling code here ----- errorCode = 1; theUI.NXMessageBox.Show("Block Styler", NXMessageBox.DialogType.Error, ex.ToString()); } return errorCode; }
