R14 ACAD Compatibilty Testing

My bad. Had $MODEL_SPACE instead of *MODEL_SPACE.

for spline & poly [attached corrected file]
73 code in text is not supported.
DICTIONARY is not available.

for basic shape

If I could prevail upon your patience once again, here are new versions. Thanks again.

I cannot open none of them in DWGTV nor in LibreCAD

outR14splinev5.dxf
outR12v5.dxf
outR14polyv5.dxf

All three files open without a hitch in LibreCAD v2.1.2 and QCad 3.15.3.

I'm at home so I can't test with DWG TrueView.

All three files open without a hitch in LibreCAD v2.1.2 and QCad 3.15.3.

I'm at home so I can't test with DWG TrueView.

When I have my act together , I test against DraftSight, LibreCad and QCad. But we've certainly had cases where a file passed all three, then crashed and burned in Autodesk s/w. So, if you're not too busy on Tuesday , a run through DWG TrueView would be great, thanks.

I can open all 3 in LC, but unfortunately I'm not able to load the 3 files in DWGTV.

ATM the exporting is working well for LibreCAD also with Bsplines ...

You may consider to use a python library to export your entities to DXF.
http://ezdxf.readthedocs.io/en/latest/t ... wings.html
The following examples are generating a Line and a BSpline file that can be displayed in DWGTV.

Code: Select all

import ezdxf

dwg = ezdxf.new('R2010')  # create a new DXF R2010 drawing, official DXF version name: 'AC1024'

msp = dwg.modelspace()  # add new entities to the model space
msp.add_line((0, 0), (10, 0))  # add a LINE entity
dwg.saveas('line.dxf')

Code: Select all

import ezdxf

dwg = ezdxf.new('AC1015')  # splines requires the DXF R2000 format or later

fit_points = [(0, 0, 0), (750, 500, 0), (1750, 500, 0), (2250, 1250, 0)]
msp = dwg.modelspace()
msp.add_spline(fit_points)

dwg.saveas("simple_spline.dxf")

The lib is able to load and to save in many DXF format version. It can also handle R12.

http://ezdxf.readthedocs.io/en/latest/i ... f-versions

Code: Select all

from random import random
from ezdxf.r12writer import r12writer

with r12writer("quick_and_dirty_dxf_r12.dxf") as dxf:
    dxf.add_line((0, 0), (17, 23))
    dxf.add_circle((0, 0), radius=2)
    dxf.add_arc((0, 0), radius=3, start=0, end=175)
    dxf.add_solid([(0, 0), (1, 0), (0, 1), (1, 1)])
    dxf.add_point((1.5, 1.5))
    dxf.add_polyline([(5, 5), (7, 3), (7, 6)])  # 2d polyline
    dxf.add_polyline([(4, 3, 2), (8, 5, 0), (2, 4, 9)])  # 3d polyline
    dxf.add_text("test the text entity", align="MIDDLE_CENTER")

May be you can handle your entities and pass those to this lib for the exporting...
The library can be installed with pip and could be deployed with the FC installer.

[NormandC]

The library can be installed with pip and could be deployed with the FC installer.

This is undesirable on Linux. You're adding another method of installing besides the operating system's method. I hate it, one of the reasons being pip is CLI only. And it's almost certain to create trouble with some Linux distributions. Linux distros don't look kindly to bundling third-party libraries either.

So ezdxf would need to be packaged in all Linux distros that provide FreeCAD.

Oh, and then there's the fact that ezdxf is dropping Python 2 support. https://ezdxf.mozman.at/dropping-python2-support.html
