js中实现代码说明：

自定义实体绘制函数

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54	`function` `ExplodeFun(pCustomEntity, pWorldDraw, txt) {` `var` `sGuid = pCustomEntity.Guid;` `if` `(sGuid ==` `"TestMxCustomEntity"``) {` `if` `(!pCustomEntity.IsHave(``"First"``))` `return``;` `var` `stp = pCustomEntity.GetPoint(``"First"``);` `var` `ept = pCustomEntity.GetPoint(``"BasePoint"``);` `var` `dimpt = pCustomEntity.GetPoint(``"DimPoint"``);` `var` `txt = pCustomEntity.GetString(``"Text"``);` `var` `textH = pCustomEntity.GetDouble(``"TextHeight"``);` `var` `edgeNum = pCustomEntity.GetLong(``"EdgeNumber"``);` `var` `shapRadius = pCustomEntity.GetDouble(``"ShapRadius"``);` `var` `isCircle = pCustomEntity.GetLong(``"isCircle"``);` `// 创建一个批注对象.` `var` `comment = mxOcx.NewEntity(``"IMxDrawComment"``);` `//标注文字` `comment.Text = txt;` `//标注文字高度` `comment.TextHeight = textH;` `//标注位置提示多边形的边数. 小于2不绘制，=2绘制圆，大于2绘制多边形` `comment.EdgeNumber = edgeNum;` `//标注位置提示多边形的半径` `comment.ShapRadius = shapRadius;` `//标注基点` `comment.basePoint = ept;` `//标注位置点` `comment.Position = dimpt;` `// 设置文字样式` `pWorldDraw.TextStyle =` `"MyCommentFont"``;` `// 动态绘制.` `pWorldDraw.DrawEntity(comment);` `if` `(isCircle) {` `var` `dR = stp.DistanceTo(ept) * 0.5;` `var` `vec = stp.SumVector(ept);` `vec.Mult(0.5);` `ept.Add(vec);` `//绘制一个圆` `//参数一为圆的中心X值，参数二为圆的中心Y值,` `//参数三为半径` `pWorldDraw.DrawCircle(ept.x, ept.y, dR);` `}` `// 绘制矩形框.` `else` `{` `//绘制一个直线` `//参数一直线的开始点x坐标，参数二直线的开始点y坐标，参数三直线的结束点x坐标，参数四直线的结束点y坐标` `pWorldDraw.DrawLine(stp.x, stp.y, stp.x, ept.y);` `pWorldDraw.DrawLine(stp.x, ept.y, ept.x, ept.y);` `pWorldDraw.DrawLine(ept.x, ept.y, ept.x, stp.y);` `pWorldDraw.DrawLine(ept.x, stp.y, stp.x, stp.y);` `}` `mxOcx.SetEventRet(1);` `}` `}`

返回自定义实体夹点

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15	`function` `GetGripPointsFun(pCustomEntity) {` `var` `sGuid = pCustomEntity.Guid;` `if` `(sGuid ==` `"TestMxCustomEntity"``) {` `if` `(!pCustomEntity.IsHave(``"First"``))` `return``;` `var` `stp = pCustomEntity.GetPoint(``"First"``);` `var` `ept = pCustomEntity.GetPoint(``"BasePoint"``);` `var` `dimpt = pCustomEntity.GetPoint(``"DimPoint"``);` `var` `ret = mxOcx.NewResbuf();` `ret.AddPoint(stp);` `ret.AddPoint(ept);` `ret.AddPoint(dimpt);` `mxOcx.SetEventRetEx(ret);` `}` `}`

移动自定义实体夹点

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29	`function` `MoveGripPointsFun(pCustomEntity, lGridIndex, dOffsetX, dOffsetY) {` `var` `sGuid = pCustomEntity.Guid;` `if` `(sGuid ==` `"TestMxCustomEntity"``) {` `if` `(!pCustomEntity.IsHave(``"First"``))` `return``;` `var` `stp = pCustomEntity.GetPoint(``"First"``);` `var` `ept = pCustomEntity.GetPoint(``"BasePoint"``);` `var` `dimpt = pCustomEntity.GetPoint(``"DimPoint"``);` `if` `(lGridIndex == 0) {` `stp.x = stp.x + dOffsetX;` `stp.y = stp.y + dOffsetY;` `pCustomEntity.SetPoint(``"First"``, stp);` `}` `else` `if` `(lGridIndex == 1)` `{` `ept.x = ept.x + dOffsetX;` `ept.y = ept.y + dOffsetY;` `pCustomEntity.SetPoint(``"BasePoint"``, ept);` `}` `else` `{` `dimpt.x = dimpt.x + dOffsetX;` `dimpt.y = dimpt.y + dOffsetY;` `pCustomEntity.SetPoint(``"DimPoint"``, dimpt);` `}` `mxOcx.SetEventRet(1);` `}` `}`

固定参数绘批注

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18	`function` `DoCommentFix() {` `var` `comment = mxOcx.NewEntity(``"IMxDrawComment"``);` `comment.Text =` `"固定参数绘批注"``;` `comment.TextHeight = 10;` `var` `basepos = mxOcx.NewPoint();` `basepos.x = 0;` `basepos.y = 10;` `var` `pos = mxOcx.NewPoint();` `pos.x = 20;` `pos.y = 30;` `//基点` `comment.BasePoint = basepos;` `//位置` `comment.Position = pos;` `var` `comobj = mxOcx.ObjectIdToObject( mxOcx.DrawEntity(comment) );` `comobj.TextStyle =` `"MyCommentFont"``;` `mxOcx.ZoomAll();` `}`

效果展示：

通过点击固定参数绘批注按钮，触发DoCommentFix()事件，CAD控件视区将显示在js中设置好的固定参数批注。如下图所示：
