如何从DXF文件中提取所有坐标 [英] How to extract all coordinates from a dxf file

问题描述

我有一个dxf文件 https://filebin.net/7l8izrv2js7doicc/5holes-8x8.dxf?t = 9ro7k928 (下载并扩展名为.dxf) 我能够将其解析为行和其他所有内容，但是我现在想提取所有坐标. 目的是，如果我获得所有坐标，则Id能够为所有这些坐标创建一个边界框. 由于该图形具有曲线和线条，因此我不知道如何为曲线等做画.

===我的显示行​​的部分代码&拔出启动和线的终点====

flist=open("test2.dxf")

#fil.readlines()
# entityflist = open("filename.txt").readlines()
lst=[]

parsing = False
for line in flist:
    #print ("==================")
    if line.startswith("ENDSEC"):
        parsing = False
    if parsing:
        #print (line)
        lst.append(line)
        #Do stuff with data 
    if line.startswith("LINE"):
        parsing = True
        #print ("LINE")

# lines coordinates list
ts=(''.join(lst).split('LINE'))

#print out all the point coordinates of lines start & end
# i.e. 2 coordinate pairs for each line
for i in ts:
    print ((i.split()[19],i.split()[21]))
    print ((i.split()[15],i.split()[17]))

解决方案

您的链接不起作用，而是发布了几行文件以显示结构，因为这是要求人们下载大文件的不良做法.

好像有一个名为ezdxf的用于处理dxf文件的库. 此处是指向他们的指南的链接，说明了如何从dxf文件中提取数据

Ive got a dxf file https://filebin.net/7l8izrv2js7doicc/5holes-8x8.dxf?t=9ro7k928 (download and name extension as .dxf) Im able to parse it for lines and all but I want to extract all coordinates now. The purpose is that if I get all the coordinates then Id be able to create a bounding box for all these coordinates. Since the drawing has curves and lines I dont know how to do it for curves etc.

===MY PARTIAL CODE TO DISPLAY LINES & pull out start & end point of lines====

flist=open("test2.dxf")

#fil.readlines()
# entityflist = open("filename.txt").readlines()
lst=[]

parsing = False
for line in flist:
    #print ("==================")
    if line.startswith("ENDSEC"):
        parsing = False
    if parsing:
        #print (line)
        lst.append(line)
        #Do stuff with data 
    if line.startswith("LINE"):
        parsing = True
        #print ("LINE")

# lines coordinates list
ts=(''.join(lst).split('LINE'))

#print out all the point coordinates of lines start & end
# i.e. 2 coordinate pairs for each line
for i in ts:
    print ((i.split()[19],i.split()[21]))
    print ((i.split()[15],i.split()[17]))

解决方案

Your link doesn't work but rather post a few lines of the file to show the structure, as it's bad practice to request people downloading huge files.

Looks like there is a library for handling dxf files called ezdxf. Here is a link to their guide on how to extract data from a dxf file
