Program start - MDT26

A construction company orders a plot survey, in which earthworks will be carried out, consisting of an embankment that will house a parking lot and subsequently the landscaping of the NW area. This area will be filled with remains of the cleared land.

First, a survey of the potentially affected area is carried out in its original state. Consequently, the calculation process with any program provides us with a file of coordinates, which we will import with the corresponding tool.

In order to issue a comparative plan of cross sections with the Administration project, we will execute the Digital Terrain Model, by using the drawing elements (polylines) that connect the topographic points as break lines. Once the DTM is prepared, we will process the cross section cuts of the plot starting from a North-South horizontal alignment bearing identical characteristics to that of the project and with a 2-meter equidistance of said cuts to compare exhaustively (by excess) with the original project that they presented at every 10.00 meters. This process will provide us with a cross section file.

Finally, after making another data sample of the modified terrain, we will obtain cuts thereof by using the same axis, and we will calculate the earthwork between both terrains.

We describe the step-by-step process, throughout the first exercises of this manual.

1.1 Program Start

Click on the MDT 26 icon located on the Windows desktop or run the MDT icon located in the MDT group created when the program was installed.

Once executed, the CAD will automatically load and the MDT application will be automatically loaded along with its menu and toolbars.
