How to render different fonts with draw_cad.py?

[ru4ert]

When i exepython ./draw_cad.py T1704180658.dxf --out image.png i get 3 times the same font:

but it should be:

T1704180658.dxf file: https://gist.githubusercontent.com/ru4ert/0f099e0ad5133b36547b5cb6663ed4c5/raw/e7b1c1e1ccba7b7004d6c21c8dcecc04814f0c51/gistfile1.txt

ezdxf 1.1.4
matplotlib 3.8.2

First always rebuild the font-manager cache: https://ezdxf.mozman.at/docs/howto/fonts.html#

I guess this DXF file was created on macOS.

Because the TTF fonts in the DXF file are named differently than on Windows:

• Comic Sans MS.ttf is comic.ttf on Windows
• Arial Black.ttf is ariblk.ttf on Windows
  ...

DWG TrueView (AutoCAD) does an auto-translation for this font names on Windows:

BricsCAD doesn't do this:

and ezdxf also doesn't do this.

If you open this DXF file on a mac the fonts should be rendered as expected - except the fonts are not stored where ezdxf is looking for.

This is the only location on macOS:

MACOS_FONT_DIRS = ["/Library/Fonts/"]

You can add more font directories to the config file at key support_dirs:

[core]
default_dimension_text_style = OpenSansCondensed-Light
test_files = C:\Source\dxftest
support_dirs =
        C:\Source\ezdxf.git\fonts\shapefiles\
        "another font directory"
        "and so on"

... and rebuild the font-manager cache.

More about config files: https://ezdxf.mozman.at/docs/options.html#config-files

Please post other default font folders if there some and I will add them to the default search locations for macOS.

FYI: you can attach DXF files to a post in a zip-archive

I added support for font-name synonyms.

The DXF file with macOS font-names on Windows:

I don't have a Mac and never will. Therefore this feature is only as good as users contribute to the font_synonyms.py file, which contains only the font-names of your sample file yet:

FONT_SYNONYMS = {
    "ariblk.ttf": "Arial Black.ttf",
    "comic.ttf": "Comic Sans MS.ttf",
    "arialuni.ttf": "Arial Unicode.ttf",
    "times.ttf": "Times New Roman.ttf",
    "trebuc.ttf": "Trebuchet MS.ttf",   
}

for me, working on mac i created a

ezdxf.ini

[core]
support_dirs =
        "/System/Library/Fonts/"
        "/Library/Fonts/"

@mozman thank you. I created a PR for an additional font dir on mac. #1004

Good to know, the dxf was created on mac as well the dxf to image is also on mac
