A: Because the exported object of mif is datasets. And the dataset is no style, so you can open this mif by MapInfo without styles.

The next step is to use the rectangular registration method to match the CAD data. Input control point coordinates information, and ensure that it is one thousandth of the coordinates of the reference point.
03 July,2019 iDesktopA: It is suggested to check the "Effective Display Clipping"; otherwise it will be clipped according to the pixel center. There may be white edge.
03 July,2019 iDesktopA: The top display in label thematic map will make the label display above all layers and won’t be covered by the geometry object.
03 July,2019 iDesktopA: In the label thematic map, the auto-avoiding will make the label location offset when the label is overlaid with each other, so as to avoid the overlapping of the label text.
03 July,2019 iDesktopA: You can check whether the objects are complex objects through the object property box. If there are multiple sub-object (the sub-object number >1, it is the complex objects). You can separate by decomposition; if it is composed of a sub-object, you can separate by "Line Segmentation" in object editing.
03 July,2019 iDesktopA: When you set the point style, you need to determine that the symbol ID is existed in the current symbol library.
03 July,2019 iDesktopA: You can right click layer menu->set color table. Then delete the default color table settings and select batch add. Set the corresponding start-end value and the appropriate step length. Then confirm.
03 July,2019 iDesktopA: When you delete the objects in dataset, the attributes of the object are also deleted. Conversely, deleting the records in a recordset will also delete a geometry object.
03 July,2019 iDesktopA: Check whether the raster dataset and the vector dataset have the same coordinate projection. If it is different, transform the raster data into the longitude and latitude projection by the dataset projection transformation and then overlay.
03 July,2019 iDesktopA: Check whether there is a required field in the property table of the dataset, but there is no default value. If so, it is suggested to create a new field to store this field. Set it to non-required or the default value, and then delete the old field.
03 July,2019 iDesktopA: (1) The driver is not installed, and it can be found under Support in installation directory of running version. (2) The lock service is not started. The lock services are Sentinel Keys Server and Sentinel Protection Server (3) The port is occupied. And what we're actually going to use is 6001, 6002, 7001, 7002 (4) Firewall. Whether the UDP\TCP port has a problem, resulting in the service request blocked. And then you look at the bottom and see what happens.
