In SCDM, we can open a text file (*.txt) containing the points coordinates of curves. It will generate automatically the curves. From the menu File > Open, select “All Files” filter and select a .txt file. The syntax in the file for 2D curves is the following: polyline=false 1 1.5 2.0 1 1.0 3.2 1 0.5 2.1 2 0.3 4.2 2 4.8 1.9 The first column contains the number (ID) of the generated line, the second column the x-coordinate and the third column the y-coordinate. The file format for 3D curve is the following: polyline=false 3d=true 0 0 1 0 1.5 1.2 1.5 0 2.3 1 1.5 4.2 1.5 1.2 5.1 2.3 4.2 6.2 5.7 3.1 2.6 With the option 3d=true, the different curves are delimited by a linebreak. The first column contains the z-coordinate, the second column the x-coordinate and the third column the y-coordinate of the points. If we attempt to import only points, we should leave a linebreak after each coordinate data.
