freecad gear模块 生成齿轮导出fcstd step

freecad：

conda install --channel https://conda.anaconda.org/conda-forge freecad

freecad .gear：下载后freecad目录下如果没有gear文件就去源码下一个

pip install https://github.com/looooo/FCGear/archive/master.tar.gz

import freecad.gears.commands
from freecad import app
app.newDocument()
gear = freecad.gears.commands.CreateInvoluteGear.create()
gear.num_teeth = 20
gear.height = 10
gear.double_helix = True
app.ActiveDocument.recompute()
app.ActiveDocument.saveAs("test.FCStd")

导出step：

import freecad.gears.commands
from freecad import app
from freecad import part
app.newDocument()
gear = freecad.gears.commands.CreateInvoluteGear.create()
gear.num_teeth = 20
gear.height = 10
gear.double_helix = True
app.ActiveDocument.recompute()
part.export([gear], "gear.step")
