A: In the Layer Control dialog box, disable the Selectable option for other layers except the layer on which you want to select objects.
08 Jul,2019 idesktopA: You can specify a filter expression in the Layer Properties dialog box to display only objects satisfying the condition.
08 Jul,2019 idesktopA: In SQL query, select Related in the field list, select two common fields from the two datasets to relate them in the dialog box that pops up. After the association, click Add and you can see the related field in the field list, which enables you to achieve related query for the two datasets.
08 Jul,2019 idesktopA: After opening the map, select the layer in the layer manager to view the properties, right click and select Associate Attributes in the context menu, click a record in the attribute table, and you will find the corresponding geometry object highlighted in the map window.
08 Jul,2019 idesktopA: The wrong buffer radius you input might cause this error. This problem mainly occurs in datasources with latitude and longitude coordinate system. Since the unit of the buffer radius is consistent with the unit of the dataset, if you are using a datasource of a latitude and longitude coordinate system, the radius is in degrees. Therefore, the number 5 you input indicates 5 degrees, not 5 meters as you expected. The solution for this problem is to convert the radius of the buffer into a value in degrees. For example, to create a 5 meters wide radius buffer, you need to convert 5 meters to 0.00004 degrees, and then input the buffer radius 0.00004 in the dialog box to generate the buffer correctly. (1 second approximately equals to 33 meters).
08 Jul,2019 idesktopA: You need to specify some initialization parameters for network analysis in ahead. Please go to Network Analysis -> Network Analysis Basic Parameter Settings, set the relevant parameters in the dialog box, and then you will find that commands for network analysis are available now.
08 Jul,2019 idesktopA: Please input the corresponding image paths of the geometric objects in a text field, set the Hyperlink Field in the Layer Manager, check Hyperlink in the Legend Manager, and finally select the Hyperlink button to display the pictures on the map. You need to note that the pictures need to be stored locally.
08 Jul,2019 idesktopA: It may be because the flight duration you specified is too short. Since the three-dimensional duration time is in milliseconds, you can set the duration to a bigger value.
08 Jul,2019 idesktopA: First of all, you need to create two texture fields TEXTURE and HEARDTEXTURE (in the type of text), input the full path of pictures into the two fields, and finally select the Tools menu -> Set 3D texture gallery path to fill in the paths. After that, you can see the texture.
08 Jul,2019 idesktopA: You can clip the image into multiple images and then overlay them with the 3D terrain.
08 Jul,2019 idesktopA: You can set the layer editable and change the styles on the Styles tab. After that, you can draw objects in a CAD layer with the specified styles.
08 Jul,2019 idesktopA: In the SuperMap desktop software, layers in the locking state cannot be set to editable. Moreover, layers in the locking state will not display in the list if you check Editable in the View Control area in the Layer Control dialog box.
08 Jul,2019 idesktopA: Please check: (1) The projection of the datasource. If the datasource is in a geographic coordinate system, please check whether the coordinates have exceeded the value ranges of longitudes and latitudes. (2) Whether there are required fields in the dataset. If yes, default values must be assigned to the required fields. Otherwise, you cannot draw objects.
08 Jul,2019 idesktopA: You can set the layer editable, select an object, click Attributes Brush on the Object Operations tab, specify fields contained by the attributes brush, and then click on the objects to which you want to paste the attributes.
08 Jul,2019 idesktopA: Operation steps are as follows: 1) Create two fields for the line dataset: centerX,centerY; 2) Update the two fields with functions: objcenterX, objcenterY; 3) Generate a point dataset by converting attributes of CenterX and CenterY into points.
08 Jul,2019 idesktopA: In the Object Editing group on the Object Operations tab, you can find Specify Coordinates in the Move Objects area to move objects through specifying the target coordinates.
08 Jul,2019 idesktopA: New objects cannot be created if the sequence table in the Oracle data source is deleted or damaged. If damaged, you can refer to the correct sequence table structure to create or modify the previous sequence table, or copy the sequence table from the backup datasource.
08 Jul,2019 idesktopA: That is probably because the user's business table contains a primary keyword and the name is not SmID, or there is an automatic growth sequence with no primary keyword. The solution is to change the primary key name of the business table to SmID, or cancel the automatic growth sequence setting of the columns of the business table without the primary key.
08 Jul,2019 idesktopA: While creating an oracle database with SuperMap, the system will generate 256 SMID_TMP* temporary tables automatically, with the serial number from 0 to 255. The number of theses temporary tables will not increase or decrease as you add or delete datasets. These tables will be used for data query. Therefore, you cannot delete them.
08 Jul,2019 idesktopA: There are two methods: (1) On the Advanced tab in Thematic Map Manager, in the Label Length Settings area, select Wrap for Over Length and specify length limit. (2) Split the text into two fields, and express them as exp1 + chr(10) + chr(13) + exp2.
