â– Change the spline No.
By selecting the file to be changed from the source or destination spline file list and then clicking the
[Renumber] button, the selected spline file No. can be changed.

(14) Import/export function
If the path point data is descried with the specified format of CSV file, that file can be imported into the
Spline File Edit screen. Using this function, position data extracted from a CAD drawing, for example, can be
written into a CSV file and then registered in a batch as the path point data. In addition to CSV files, point
sequence data (MXT files) output from MELFA-Works can be imported.
The path point data registered from the Spline File Edit screen can be exported as a CSV file. Using this
function, the details of the path point data can be confirmed even without starting the Spline File Edit screen.
â– CSV file format
The data shown in Table 7-15 is described in the CSV file as the path point data. Commas (,) are used as
delimiters. The data is written so that one path point data is shown on one line.
