Units in DXF Codes

[SteveK]

Hi folks,

 

I am dealing with the output of dxf code 10 and it is something like

597455.0 7.64557e+006 345.57

Does anyone know if these units are set somewhere? I would like to change the units to 4 decimal places.

 

Appreciate your time,

I thought they stored the double-precision point, not a "rounded" version.

[SteveK]

Yeah they do, the problem (that I'm sure you've faced with your PtM) is when I'm directly taking those values (as they appear) and copying them to somewhere outside autocad.

Ahh, good point - I've used vl-princ-to-string, as for the small values I've tested it on, nothing seems out of place, but I think I shall have to change to rtos, which follows the users LUPREC LUNITS sysvars.

[SteveK]

I just noticed that with your program too! You might have to add a precision option. But anyways, rtos does the trick for my purposes, will have to separate each co-ord component and reassemble again.

Nah:

 

(mapcar (function rtos) pt)

 

The precision is fine, it will just use the precision that the user has set.

Ah, good one!
