尝试获取 Catia V5 Part 中 PartBody 的 Sketch1 几何图形内特定点的坐标。
import win32com.client
from pycatia import catia
# Open the CATIA document
caa = catia()
# Open the CATIA document
documents = win32com.client.Dispatch('CATIA.Application').Documents
file_name = './Part.CATPart'
part_document = documents.Open(file_name)
part = part_document.Part
bodies = part.Bodies
body = bodies.Item('PartBody')
# Access the Sketch
sketches = body.Sketches
sketch = sketches.Item('Sketch.1')
# Open the sketch for edition
factory2D = sketch.OpenEdition()
# Access the geometric elements in the sketch
geometric_elements = sketch.GeometricElements
# Find the specific point by name
point_name = 'Point.22'
point = None
for i in range(1, geometric_elements.Count + 1):
element = geometric_elements.Item(i)
if element.Name == point_name:
point = element
break
# Check if the point was found and retrieve its coordinates
if point is not None:
try:
# Assuming the point has X, Y properties directly accessible
x = point.X
y = point.Y
print(f"Coordinates of {point_name}: X={x}, Y={y}")
except AttributeError as e:
print(f"{point_name} found but coordinates could not be retrieved: {e}")
try:
coord = point.GetCoordinates()
except Exception as e:
print(e)
else:
print(f"{point_name} not found in the sketch.")
# Close the sketch edition
sketch.CloseEdition()
这会引发错误,第一个我不知道如何访问点坐标,所以我正在尝试 point.X,但是这就引发了:
Point.122 found but coordinates could not be retrieved: Item.X
也尝试该方法
GetCoordinates()
但这会引发
(-2147352567, 'Ocurrió una excepción.', (0, 'CATIAPoint2D', 'The method GetCoordinates failed', None, 0, -2147467259), None)
有什么建议吗?谢谢!
你的代码中出现错误是因为
pycatia
中的
Point
对象没有
X
或
Y
属性,而
GetCoordinates()
方法在
HybridShapePointCoord
对象(表示三维空间中的一个点)中可用,但不用于草图中的二维点。
以下是如何使用
pycatia
获取 CATIA V5 草图中一个点的坐标的方法:
import win32com.client
from pycatia import catia
# 初始化 CATIA
caa = catia()
# 获取活动文档
document = caa.active_document
# 选择 Part
part = document.part
# 选择 PartBody
bodies = part.bodies
body = bodies.Item("PartBody")
# 选择草图
sketches = body.sketches
sketch = sketches.Item("Sketch.1")
# 获取草图中的点
point_name = "Point.22"
point = sketch.geometric_elements.Item(point_name)
# 获取点的 2D 坐标
# 注意:这返回一个数组,其中包含点的 X 和 Y 坐标
coordinates = point.GetCoordinates()
x = coordinates[0]
y = coordinates[1]
print(f"点 {point_name} 的坐标为:X={x}, Y={y}")
本代码首先获取了对草图中点的引用。然后,它使用
GetCoordinates()
方法获取点的坐标,该方法返回一个包含 X 和 Y 坐标的数组。最后,它打印出点的坐标。
注意: 本代码假定草图“Sketch.1”和点“Point.22”存在于文件中。你需要根据你的 CATIA 文件更新这些名称。
