How can I cut out an area from a region object in a dataset?

Why cannot I add objects to an editable point layer even if I recalculated the index and copied data to another dataset？

How can I fill in the gaps between two different line datasets (objects in two datasets overlap)?

How can I convert a map in planar coordinate system into longitude and latitude coordinate system such as wgs84?

How can I generate a region dataset for contour line dataset while keeping the elevation information of the contour lines?

How can I set symbols not to overlap with labels?

How can I convert the generated network dataset into a region dataset?

How can I specify different symbols and rotation angles for different classes of points for a point layer?

Where can I check the specified maximum and minimum visible scales specified for a layer?

Why cannot I overlay a vector dataset and a raster dataset correctly in SuperMap even though they can overlay well in ArcGIS? They are both in WGS84, and after been imported into SuperMap, the vector dataset displays correctly but the raster dataset display wrongly. Why does this happen?

Why cannot I see the text after importing the Arcgis shp text file? Why does the Arcgis shp text file become a point dataset after being imported into SuperMap?

How can I convert small values for the smarea field of the region dataset imported into the oracle datasource to the real areas?

Why did I fail to generate network dataset from line datasets with all parameters specified correctly?

How can I rotate maps with symbols not rotated?

Why is the color of the image dataset imported from the tiff image white with no features display?

How can I optimize the slow browsing speed of the network dataset in the oracle datasource?

How can I find the differences between two datasets that have slight changes no matter they are raster or vector datasets?

The block object inserted in the CAD has the value of Z scale factor. However, the value cannot be read while being imported into SuperMap. How can I read the Z scale factor value of the block object in CAD?

Can a SIT file have projection file similar to the tfw coordinate file of a tiff file?

How can I perform the dissolve operation for multiple adjacent objects in a region dataset for administrative regions if each of those adjacent objects is composed of multiple child objects?
