Creating a surface from a point cloud - MDT25

7.3 Creating a Surface from a Point Cloud

Next we will create a surface from a selection of the points in the previously inserted point cloud. Run Surfaces > Create Surface and create a new file PNOA.sup in the folder mentioned above.

In the dialog, activate the Point Cloud checkbox as well as the Maximum Length checkbox, where we will set a value of 50. In the Representation options, choose the Contour option to avoid overloading the drawing.

Press the Designate Clouds button and designate the recently inserted cloud.

In the dialog, press the Check number of points button and verify that there are about 14 million.

Press the Categories button and, as shown above, select only category 2-Ground and press Accept.

Set plan view and run Contouring/Cartography > Contour, with contour intervals Normal every 10 metres and Index every 50 metres.

Save the drawing as PNOA.dwg in the project folder.
