arrays - ファイルから頂点位置を読み取る際の Blender from_pydata エラー

Question

エラーが発生します。

Error: Array length mismatch (expected 3, got 13)
TypeError: a float is required
Traceback (most recent call last):
File "\Test.py", line 393, in from_pydata
File "C:\Program Files (x86)\Blender Foundation\Blender\2.68\2.68\scripts\modules\bpy_types.py", line 393, in from_pydata
self.vertices.foreach_set("co", vertices_flat)
TypeError: couldn't access the py sequence
Error: Python script fail, look in the console for now...

コードは次のとおりです。

filePath = "C:\\Users\\siba\\Desktop\\1x1x1.blb"

f = open(filePath)
line = f.readline()

while line:
    if(line == "POSITION:\n"):
        POS1 = f.readline().replace('\n','')

    line = f.readline()
f.close()

coord1 = POS1
Verts = [coord1]


import bpy
profile_mesh = bpy.data.meshes.new("Base_Profile_Data")
profile_mesh.from_pydata(Verts, [], [])
profile_mesh.update()
profile_object = bpy.data.objects.new("Base_Profile", profile_mesh)
profile_object.data = profile_mesh
scene = bpy.context.scene
scene.objects.link(profile_object)
profile_object.select = True

1x1x1.blb は次のとおりです。

POSITION:
0.5 0.5 0.5
