项目需要自动出2D零件图,可是我之前没做过这方面的内容,没有一点思路。然后我就做了下面几件事:
1、百度、google翻了一遍,搜索关键字“UG二次开发自动出图”
2、csdn.com 和 cnblogs.com翻了一遍
3、平时逛的qq技术群,微信技术群问候了一遍
4、做二开之后结交的技术大牛、小达人请教了一遍
现在有了一点思路,整理出来,自己也写了一部分主要源码分享出来供大家欣赏。
自动出图方案经过我一番辛苦整理后,需要完成以下几步:
1、出图方案设置
出图方式千千万,每个人都有自己的想法,我们需要先定一个标准,然后程序才能按照标准自动出图,标准如下:
1)图纸参数设置,包括图纸类型,视图比例,图纸名称
2)视图布局方案,根据用户需求对视图进行布局,视图包括:顶视图、左视图、右视图、后视图、底视图、正三轴视图、右剖视图、底剖视图。
3)标注方案,目前我想到的先从简单的平面尺寸开始,先做水平、垂直、角度的标注
2、自动创建图纸、自动创建视图
3、自动标注
1、创建图纸
///
/// 创建图纸
///
///
///
public static Tag CreatDWG(Part workPart,string sheetName)
{
NXOpen.Drawings.DrawingSheet nullDrawings_DrawingSheet = null;
NXOpen.Drawings.DrawingSheetBuilder drawingSheetBuilder1;
drawingSheetBuilder1 = workPart.DrawingSheets.DrawingSheetBuilder(nullDrawings_DrawingSheet);
drawingSheetBuilder1.StandardMetricScale = NXOpen.Drawings.DrawingSheetBuilder.SheetStandardMetricScale.S11;
drawingSheetBuilder1.EnglishSheetTemplateLocation = "";
drawingSheetBuilder1.Height = 297.0;
drawingSheetBuilder1.Length = 420.0;
drawingSheetBuilder1.StandardMetricScale = NXOpen.Drawings.DrawingSheetBuilder.SheetStandardMetricScale.S11;
drawingSheetBuilder1.StandardEnglishScale = NXOpen.Drawings.DrawingSheetBuilder.SheetStandardEnglishScale.S11;
drawingSheetBuilder1.ScaleNumerator = 1.0;
drawingSheetBuilder1.ScaleDenominator = 1.0;
drawingSheetBuilder1.Units = NXOpen.Drawings.DrawingSheetBuilder.SheetUnits.Metric;
drawingSheetBuilder1.ProjectionAngle = NXOpen.Drawings.DrawingSheetBuilder.SheetProjectionAngle.First;
drawingSheetBuilder1.Number = "1";
drawingSheetBuilder1.SecondaryNumber = "";
drawingSheetBuilder1.Revision = "A";
drawingSheetBuilder1.Name = sheetName;
drawingSheetBuilder1.MetricSheetTemplateLocation = "D:\\Program Files\\Siemens\\NX 8.0\\localization\\prc\\simpl_chinese\\startup\\A3-noviews-template.prt";
NXObject nXObject1;
nXObject1 = drawingSheetBuilder1.Commit();
drawingSheetBuilder1.Destroy();
return nXObject1.Tag;
}
这里只是一个粗略的创建图纸,参数还没抽取出来,因为调用的是系统模板,后面应该会根据模板类型分别调用,也可以用自定义模板来创建图纸。
2、创建视图
///
/// 创建基本视图(ufun)
///
///
public static void CreateView(Tag drawTag, string viewName, Point3d point,out Tag viewTag, out Tag drawViewTag)
{
Session theSession = Session.GetSession();
Part workPart = theSession.Parts.Work;
Part displayPart = theSession.Parts.Display;
theUFSession = UFSession.GetUFSession();
viewTag = Tag.Null;
//根据名字获取视图的Tag
theUFSession.Obj.CycleByNameAndType(workPart.Tag, viewName, UFConstants.UF_view_type, false, ref viewTag);
double[] dwg_point = new double[2] { point.X, point.Y };
UFDraw.ViewInfo viewInfo = new UFDraw.ViewInfo();
theUFSession.Draw.InitializeViewInfo(out viewInfo);
drawViewTag = Tag.Null;
//初始化视图信息
theUFSession.Draw.ImportView(drawTag, viewTag, dwg_point, ref viewInfo, out drawViewTag);
theUFSession.Draw.UpdateOneView(drawTag, drawViewTag);//更新视图
}
这里通过ufun方法创建视图,可以完成根据viewName创建各种视图,包括顶视图、左视图、右视图、后视图、底视图、正三轴视图、右剖视图、底剖视图。
目前这个方法能基本符合需求,难点在于视图的位置point怎么确定下来?
3、创建垂直标注尺寸
//ufun创建垂直尺寸
UFDrf.Object object1 = new UFDrf.Object();
UFDrf.Object object2 = new UFDrf.Object();
object1.object_view_tag = topDrawViewTag;
object1.object_assoc_type = UFDrf.AssocType.EndPoint;
object1.object_assoc_modifier = UFConstants.UF_DRF_last_end_point;
object1.object_tag = edgeStart;
object2.object_view_tag = topDrawViewTag;
object2.object_assoc_type = UFDrf.AssocType.EndPoint;
object2.object_assoc_modifier = UFConstants.UF_DRF_first_end_point;
object2.object_tag = edgeEnd;
UFDrf.Text drf_text = new UFDrf.Text();
drf_text.user_dim_text = "";
drf_text.lines_app_text = 0;
drf_text.appended_text = "";
double[] dimension_3d_origin = new double[3] { 50, 200, 0 };
Tag dimTag1 = Tag.Null;
theUFSession.Drf.CreateVerticalDim(ref object1, ref object2, ref drf_text, dimension_3d_origin, out dimTag1);
使用了ufun函数theUFSession.Drf.CreateVerticalDim来创建垂直尺寸,能实现标注的创建,但是问题还有很多:
1、各种视图分别需要哪些标注
2、如何创建需要的标注
3、标准的摆放位置的确定也是一个难点
4、调用主方法
public static int Main(string[] args)
{
theSession = Session.GetSession();
theUFSession = UFSession.GetUFSession();
displayPart = theSession.Parts.Display;
workPart = theSession.Parts.Work;
theUI = UI.GetUI();
int retValue = 0;
try
{
#region 创建标注
Body rightBody = null;
BodyTool.GetRightBody(theSession, out rightBody);
Auto_Init.BodyInit init = new Auto_Init.BodyInit(rightBody);
BodyModel model = init.ProcBody();
int moduleid;
theUFSession.UF.AskApplicationModule(out moduleid);
if (moduleid != UFConstants.UF_APP_DRAFTING)
{
theUI.MenuBarManager.ApplicationSwitchRequest("UG_APP_DRAFTING");
}
//新建图纸
Tag topViewTag, leftViewTag, tfrViewTag;
Tag topDrawViewTag, leftDrawViewTag, tfrDrawViewTag;
Tag dragTag = DrawTool.CreatDWG(workPart, "Sheet1");
Point3d point1 = new Point3d(120, 200, 0.0);
DrawTool.CreateView(dragTag, "TOP", point1, out topViewTag, out topDrawViewTag);
Point3d point2 = new Point3d(120, 80, 0.0);
DrawTool.CreateView(dragTag, "LEFT", point2, out leftViewTag, out leftDrawViewTag);
Point3d point3 = new Point3d(300, 180, 0.0);
DrawTool.CreateView(dragTag, "TFR-ISO", point3, out tfrViewTag, out tfrDrawViewTag);
Tag edgeStart = Tag.Null;
Tag edgeEnd = Tag.Null;
theUFSession.Obj.CycleByName("EDGESTART1", ref edgeStart);
theUFSession.Obj.CycleByName("EDGEEND1", ref edgeEnd);
//ufun创建垂直尺寸
UFDrf.Object object1 = new UFDrf.Object();
UFDrf.Object object2 = new UFDrf.Object();
object1.object_view_tag = topDrawViewTag;
object1.object_assoc_type = UFDrf.AssocType.EndPoint;
object1.object_assoc_modifier = UFConstants.UF_DRF_last_end_point;
object1.object_tag = edgeStart;
object2.object_view_tag = topDrawViewTag;
object2.object_assoc_type = UFDrf.AssocType.EndPoint;
object2.object_assoc_modifier = UFConstants.UF_DRF_first_end_point;
object2.object_tag = edgeEnd;
UFDrf.Text drf_text = new UFDrf.Text();
drf_text.user_dim_text = "";
drf_text.lines_app_text = 0;
drf_text.appended_text = "";
double[] dimension_3d_origin = new double[3] { 50, 200, 0 };
Tag dimTag1 = Tag.Null;
theUFSession.Drf.CreateVerticalDim(ref object1, ref object2, ref drf_text, dimension_3d_origin, out dimTag1);
#endregion
}
catch (NXOpen.NXException ex)
{
}
return retValue;
}
以上只是一个不完整的思路和实现方案,希望有懂的大佬给一些建议,后续我会继续完善这一块内容并无偿分享给大家。
