  • All you have shown is bits of the header section of the DXF file. You could find yourself a DXF oarser library which may well have built in tools to do what you want. Otherwise you have to manually parse the entities and work it out. – Andrew Truckle Dec 22 '20 at 12:34
  • @AndrewTruckle is right, The header does contain extmin and extmax but this is not guaranteed to be accurate to the bounds of your document, not at all. -- Your best bet is to parse through the entities and when you see the x flag, check if it is smaller than your smallest or larger than your largest. This could potentially take some time depending on how large your file is. – CodeJunkie Feb 05 '21 at 03:07
  • @CodeJunkie What’s more, they need to be aware some entities are not stored in WCS coordinates and may need transformation. And if it has complex entities like splines this task would be a nightmare. – Andrew Truckle Feb 05 '21 at 05:18
