UG/NX二次開發(fā)(C#)自動刻字三部曲1-打印文本-創(chuàng)新互聯(lián)

自動刻字功能是建模過程中必須用到的，但是網(wǎng)上沒有找到完整的刻字功能實現(xiàn)，所以我花了一些時間寫了一套簡易程序，希望能給初學者帶來一點幫助

目前成都創(chuàng)新互聯(lián)已為超過千家的企業(yè)提供了網(wǎng)站建設、域名、網(wǎng)站空間、綿陽服務器托管、企業(yè)網(wǎng)站設計、烏翠網(wǎng)站維護等服務，公司將堅持客戶導向、應用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。

先介紹一下建模環(huán)境下刻字功能的實現(xiàn)，分三步走（本節(jié)主要介紹打印文本）：

第一步：打印文本

第二步：拉伸

第三步：布爾求差

                    Extrude(fea.JournalIdentifier,dir);//執(zhí)行拉伸命令
                    return fea.JournalIdentifier;

            return "";

打印文本的源碼是經(jīng)過錄制修改而來，所以有部分源碼我也還沒完全整明白；

主要實現(xiàn)了NXOpen.Features.TextBuilder這個類來完成文本打印。

其中，需要注意的地方有：

1、要確保文本打印在面上，這里實現(xiàn)了一個智能點

point1 = workPart.Points.CreatePoint(face1, scalar1, scalar2, NXOpen.SmartObject.UpdateOption.WithinModeling);

2、文本在面上之后，怎么擺正文本又是一個問題，所以用到了笛卡爾坐標系

CartesianCoordinateSystem cartesianCoordinateSystem1 = (CartesianCoordinateSystem)workPart.FindObject("ENTITY 45 1");
            cartesianCoordinateSystem1.RemoveParameters();
            Point3d origin2 = new Point3d(p.X, p.Y, p.Z);
            cartesianCoordinateSystem1.Origin = origin2;
            Vector3d xDirection1 = new Vector3d(1, 0, 0);
            Vector3d yDirection1 = new Vector3d(0, 1, 0);
            if (dir[2] == 1)
            {
                xDirection1 = new Vector3d(1, 0, 0);
                yDirection1 = new Vector3d(0, 1, 0);
            }
            else if (dir[2] == -1)
            {
                xDirection1 = new Vector3d(1, 0, 0);
                yDirection1 = new Vector3d(0, -1, 0);
            }
            else if (dir[1] == 1)
            {
                xDirection1 = new Vector3d(-1, 0, -0);
                yDirection1 = new Vector3d(-0, -0, 1);
            }
            else if (dir[1] == -1)
            {
                xDirection1 = new Vector3d(1, 0, 0);
                yDirection1 = new Vector3d(0, 0, 1);
            }
            else if (dir[0] == 1)
            {
                xDirection1 = new Vector3d(-0.0, 1.0, -0.0);
                yDirection1 = new Vector3d(-0.0, -0.0, 1.0);
            }
            else if (dir[0] == -1)
            {
                xDirection1 = new Vector3d(0.0, -1.0, 0.0);
                yDirection1 = new Vector3d(-0.0, -0.0, 1.0);
            }
            cartesianCoordinateSystem1.SetDirections(xDirection1, yDirection1);
            textBuilder1.PlanarFrame.UpdateOnCoordinateSystem();

開發(fā)過程中，大家可以用下面的代碼顯示出笛卡爾坐標系，以輔助開發(fā)cartesianCoordinateSystem1.SetVisibility(SmartObject.VisibilityOption.Visible);

3、這里還有一個大大坑，就是創(chuàng)建的文本沒有返回Tag，所以我這里通過在Commit()方法前后分別獲取所有的特征對象的方式，才獲取到創(chuàng)建的文本

ListfeaList = new List();
            feaList = GetFeatureList();

            NXObject nXObject2;
            nXObject2 = textBuilder1.Commit();

            textBuilder1.Destroy();

            foreach (Feature fea in workPart.Features)
            {
                if (!feaList.Contains(fea))
                {
                    Extrude(fea.JournalIdentifier,dir);//執(zhí)行拉伸命令
                    return fea.JournalIdentifier;
                }
            }
