Question

使用产品：iobjects 10.2  操作系统：win10 x64
数据类型：文件型
问题详细描述：在三维平面场景中导入CAD和SHP数据，不显示。但在桌面端iDesktop导入正常显示。
 

                if (dataset.Type == DatasetType.Line3D)
                {
                    Layer3DSettingVector layer3DSettingVector = new Layer3DSettingVector();

                    GeoStyle3D geoStyle3D = new GeoStyle3D
                    {
                        AltitudeMode = AltitudeMode.ClampToGround,
                    };
                    layer3DSettingVector.Style = geoStyle3D;

                    // 这两行代码都不在平面场景中显示
                    //mLayersControl.Scene.Layers.Add(dataset, layer3DSettingVector, true);
                    mLayersControl.Scene.Layers.Add(dataset, layer3DSettingVector, true);
                }
                else if (dataset.Type == DatasetType.CAD)
                {
                    Layer3DSettingVector layer3DSettingVector = new Layer3DSettingVector();

                    GeoStyle3D geoStyle3D = new GeoStyle3D
                    {
                        AltitudeMode = AltitudeMode.ClampToGround,
                    };

                    layer3DSettingVector.Style = geoStyle3D;

                    // 这两行代码都不在平面场景中显示
                    mLayersControl.Scene.Layers.Add(dataset, layer3DSettingVector, true);
                    //mLayersControl.Scene.Layers.Add(dataset, (Layer3DSetting)null, true);
                }

cad和shp你具体是导入成了什么数据集？

您这边具体定位目前是导入为数据集的数据集不正常，还是任意数据数据集作为图层加载在场景里后，刷新场景图层和图层里的东西不显示？

---

数据集正常，该数据集导入iDesktop后，场景里面正常显示。

但是作为图层加载在场景里后，刷新场景不显示，图层管理器中有该图层。然而仍然定位到该图层，场景中没有任何内容。

---

我建议您控制单一情况测试才能定位到具体出现问题的原因，

使用代码导入数据集，代码导入的数据集在桌面端看；（不正常则导入数据集代码有问题）

使用桌面新建的一份正常数据集集，在代码里看；（不正常则加图层代码有问题）

诸如此类，建议您先定位到具体问题在哪里。
