[Softimage][Maya]Curves data transfer

Coding
1

My first post here, after oogling at other people posts for a long time.

I’m trying to recreate curves in Maya with data collected in Softimage, and I guess later vice-versa. Does anybody have any hints or ideas for this?

The curves are being collected in Softimage with this method: Object Model: NurbsCurveList.Get2

Out of interest, is there any reason fbx couldn’t be used for this? If the names are the same and you can filter selections it should just copy the same curve data between the two applications.

If you want to do alterations and you’re happy doing some scripting you could use the python fbx sdk to run name modification/mappings etc.

Thanks for your suggestion, Mike. Trying to keep code as independent as possible, so would rather work directly with the data instead.

Got some help with this elsewhere, but posting here if anyones interested.

import maya.cmds as cmds


def create_curve(data):

    crvs = list()
    steps = data[2]
    for i in range(data[0]):
        pts = zip(*data[1][:-1])[sum(steps[:i]):sum(steps[:i + 1])]
        if data[5][i]:  # closed curve
            pts.append(pts[0])
        crvs.append(cmds.curve(degree=1, p=pts))
    
    #combining curves
    node = cmds.group(empty=True)
    for crv in crvs:
        shp = cmds.listRelatives(crv,shapes=True)
        cmds.parent(shp, node, r=True, s=True)
        cmds.delete(crv)

# data sample comes from rigicon/config/Main.py
data = (3, ((-2.7755575615628914e-17, -2.7755575615628914e-17, -0.5, 0.5, -2.7755575615628914e-17, -2.7755575615628914e-17), (0.0, 0.0, 0.0, 0.0, 0.5, -0.5), (0.5, -0.5, 3.0616171314629196e-17, -3.0616171314629196e-17, -3.0616171314629196e-17, 3.0616171314629196e-17), (1.0, 1.0, 1.0, 1.0, 1.0, 1.0)), (2, 2, 2), ((0.0, 0.0, 0.0), (1.0, 1.0, 1.0)), (2, 2, 2), (False, False, False), (1, 1, 1), (1, 1, 1))
create_curve(data)

This is for a Maya port of the rigicon framework, being developed by Cesar Saez (GitHub - csaez/rigicon: Curve/icon library for Softimage.).
