Can the import spline from csv sample be used to import just points?

[MichaelAubry]

Hello!

I've been trying unsuccessfully to figure out how to use the import just points and not have it automatically create a spline. Is there a way to accomplish this?

Here's the original python script:

import adsk.core, adsk.fusion, traceback

def run(context):

ui = None

try:

app = adsk.core.Application.get()

ui = app.userInterface

# Get all components in the active design.

product = app.activeProduct

design = product

title = 'Import Spline csv'

if not design:

ui.messageBox('No active Fusion design', title)

return

dlg = ui.createFileDialog()

dlg.title = 'Open CSV File'

dlg.filter = 'Comma Separated Values (*.csv);;All Files (*.*)'

if dlg.showOpen() != adsk.core.DialogResults.DialogOK :

return

filename = dlg.filename

f = open(filename, 'r')

points = adsk.core.ObjectCollection.create()

line = f.readline()

data = []

while line:

pntStrArr = line.split(',')

for pntStr in pntStrArr:

data.append( float(pntStr))

if len(data) >= 3 :

point = adsk.core.Point3D.create(data[0], data[1], data[2])

points.add(point)

line = f.readline()

data.clear()

f.close()

root = design.rootComponent;

sketch = root.sketches.add(root.xYConstructionPlane);

sketch.sketchCurves.sketchFittedSplines.add(points);

except:

if ui:

ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Thanks!

This should do it.

import adsk.core, adsk.fusion, traceback

def run(context):
    ui = None
    try:
        app = adsk.core.Application.get()
        ui = app.userInterface

        # Get all components in the active design.
        product = app.activeProduct
        design = product
        title = 'Import Spline csv'

        if not design:
            ui.messageBox('No active Fusion design', title)
            return
 
        dlg = ui.createFileDialog()
        dlg.title = 'Open CSV File'
        dlg.filter = 'Comma Separated Values (*.csv);;All Files (*.*)'
        if dlg.showOpen() != adsk.core.DialogResults.DialogOK :
            return

        root = design.rootComponent;
        sketch = root.sketches.add(root.xYConstructionPlane)
        sketch.name = 'CSV Points'
            
        filename = dlg.filename
        f = open(filename, 'r')
        line = f.readline()
        data = []
        while line:
            pntStrArr = line.split(',')
            for pntStr in pntStrArr:
                data.append(float(pntStr))
         
            if len(data) >= 3 :
                point = adsk.core.Point3D.create(data[0], data[1], data[2])
            data.clear()

            sketch.sketchPoints.add(point)
            line = f.readline()

        f.close()
    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

That's it!  Thanks a lot Brian!  No way I would have got that on my own.  Thanks so much for your help.

This is a little late, but here's a variation of the CSV import code that I created that allows creating of just points, lines, or splines:

https://github.com/hanskellner/Fusion360ImportCSVPoints

It also supports multiple line/spline creation by inserting a blank line between groups of points within the CSV file.

I created it for another app I'm working on.

This modified plugin with the option for lines or splines is EXACTLY what I needed! Thanks!

[hanskellner]

Please let me know if you run into any issues.  I haven't touched the code for a while now and hope it still works.

[adamonline45]

hanskellner, that's exactly what I needed, too! Great timing, and great solution 😄

This is what the standard fusion function should be!   Units, points, lines, and splines.  PERFECT, Thank you!

Hi guys, I am really late to this but I am hoping if you could help me here. I have followed the instructions and copied the files to the new script folder. Looks like currently Fusion360 only recognizes Python and C++ codes whereas the sources files on github are javascripts. What am I missing here? 

[hanskellner]

Hi @Anonymous -

Yes, if you're speaking about my Fusion360ImportCSVPoints script, the current version posted is no longer supported.  But I am finishing up a new version and hope to have it posted in a day.

[Anonymous]

Great! Thanks!

[hanskellner]

I have posted a new version of Import CVS Points on Github.  Please download and install this version.  Also, be sure to read the README for details of this version and the updates.

Thanks

I'm having trouble with the new script and units.   No matter what units I select, it imports as if the CSV is in cm. 

[hanskellner]

Hi @Anonymous -

Sorry it's not working.  Ok, I found the issue.  It wasn't setting (internally) the user's default unit type.  The UI would show it correctly but it wasn't using it.

I've updated the code on the Github site.

Thanks for reporting this.

Thanks

No worries,  I could just be using it wrong.   its been a couple of months since I used the previous version, so maybe I was having python convert my csv to cm before importing it into fusion.  

I have been working with python to create the CSV points and have been working exclusively with units of feet.  So I just changed lines 51 and 52 in the python file to 'ft' instead of 'cm' and it works for my purposes.  

[hanskellner]

You're using it the right way. I just goofed but now it's fixed. Your mod to the source code is also a quick fix for your specific use case.

@hanskellner Thank you so much for the plug-in!  That is really great.

I am looking to extrude pipes through those lines, I have seen there is a script for making pipes, but I am so confused with the code. I will much appreciate it if anyone can help.
