MDT has two ways of representing points: either as blocks having attributes or as special objects (MDT points). The former has the advantage that they can be handled on a computer that does not have MDT installed. Their disadvantage lies in the fact that processing such points is much slower. Independently of the object type, each point stores a name or number, a code and a level, in addition to its coordinates. When the entity is an MDT point, additional attributes can also be included with the observation data for the point (GPS or total stations), hyperlinks, and data defined by the user. To change between one or another representation use the command Tools > Configuration > Points and select at the top the type of representation to be used.
Point coordinates can be modified either with the application’s own utilities or directly using the CAD commands, including: DELETE, MOVE, ROTATE, UNDO, etc. The difference between both command categories is that the program’s commands offer greater possibilities and easier selection possibilities.
Depending on the type of object used to represent points, the attributes appear in separate layers (block type objects) or in the same layer (MDT point objects).
