Spline surface and volume creation with Python API

[mankatmalte-dev]

Hi,

I know it’s possible to create a spline line from points using the API, but I was wondering if it’s also possible to create:

• a spline surface from lines
• a spline volume from surfaces

Basically, can this be done through the Python API the same way it can be done directly in Cadwork?

I looked through the API reference but couldn’t find any function or command for this.

Thanks!

I haven't found a way. Tried with convert_lines_to_surfaces(lines) and create_surface(points) (so the next person trying to solve that doesn't need to try the same things).

The only way this gives me a surface is if points contains 4 points or less.

import cadwork
import element_controller as ec
import geometry_controller as gc
import attribute_controller as ac

def main():
   
    line_coordinates = [
        [(0,0,0),(0,100,0)],
        # [(45.45,0,0),(45.45,90.91,9.09)],
        # [(90.91,0,0),(90.91,81.82,18.18)],
        # [(136.36,0,0),(136.36,72.73,27.27)],
        # [(181.82,0,0),(181.82,63.64,36.36)],
        # [(227.27,0,0),(227.27,54.55,45.45)],
        # [(272.73,0,0),(272.73,45.45,54.55)],
        # [(318.18,0,0),(318.18,36.36,63.64)],
        # [(363.64,0,0),(363.64,27.27,72.73)],
        # [(409.09,0,0),(409.09,18.18,81.82)],
        # [(454.55,0,0),(454.55,9.09,90.91)],
        [(500,0,0),(500,0,100)],
    ]

    lines = [] 
    points = []
    for line in line_coordinates:
        p1 = cadwork.point_3d(line[0][0], line[0][1], line[0][2])
        points.append(p1)
        p2 = cadwork.point_3d(line[1][0], line[1][1], line[1][2])
        points.append(p2)
        lines.append(ec.create_line_points(p1, p2))
    
    print(ec.convert_lines_to_surfaces(lines)) # -> this returns []
    print(ec.create_surface(points)) # -> this crashes cadwork with more than 4 points

    main()
