ImportSplineAnyCSV for Fusion 360

A Fusion 360 script that import spline from any CSV file.

It reads data from a CSV file and creates a spline in a sketch. It supports:

• two colunms and three columns data
• numbers with a comma as the decimal separator
• any kind of separator between values
• automatic text header skipping

Since the version 1.2.0, it is possible to import multiple splines from one CSV file by separate them with empty lines. You have to edit the file ImportSplineAnyCSV.py with a text editor and set the TREAT_EMPTY_LINES_AS_SPLINES_SEPARATOR variable to True:

TREAT_EMPTY_LINES_AS_SPLINES_SEPARATOR = True

If you want to import data as one spline only, you have to set the TREAT_EMPTY_LINES_AS_SPLINES_SEPARATOR variable to False:

TREAT_EMPTY_LINES_AS_SPLINES_SEPARATOR = False

There is also an option to create the splines in a single sketch by setting the following variable to False:

ONE_SKETCH_PER_SPLINE = False

If the variable is set to True, each spline is created in its own sketch:

ONE_SKETCH_PER_SPLINE = True

Since version 1.5.0, it is possible to scale the input data by modifying the SCALE_FACTOR variable:

SCALE_FACTOR = 1.0

Acknowledgement

This script is inspired by the "ImportSplineCSV" script from Autodesk. Some users faced issues when trying to import some CSV files using this script: Import Spline CSV script "no valid points". So I modified the part of the code where the data are read to make the reading more flexible.
