Engraving Fonts

My system is omitting some of the lines for the engraving texts for certain letters. The error seems to be with B and D and occurs on a couple of fonts but works fine on others.

Ignore the upside down-ness.

Is there anyway around this? The font I want to use is one which creates the error. The first image is an example of the error, the second is a successful font.

Furthermore is there anyway that we could be able to access single-stroke fonts from the windows font directory/from rhino so that I could input my choice of single stroke fonts?

Thanks for your time,

Jackson

Hi Jackson,

this is a known bug. Some letters don't work on some fonts. This is due to a cleaning algorithm, that is removing all duplicate pieces and simplifying the path in a manner, that it does not have segments. This is important if you laser or mill the font, because segments will raise a lot the processing time of the mill or laser. Also duplicate pieces aren't that nice.

I've attached a script, where i've removed the cleaning algorithm from the EngraveText component, so you can try it with that component. Otherwise you can install the font on windows and create a text object in rhino. I do not recommend this, because the fonts aren't working well in rhino and you will get the same result as in the component attached. But give it a try.

Copy this path to your windows explorer address bar. All fonts from the EngraveText component should be cached to this location.

%AppData%/Grasshopper/UserObjects/CamBamFonts/

Good luck and thanks

Florian,

Thank you for the response and for the script. I have a couple more questions:

Why do segments increase CNC time? By simple virtue of requiring more linear length to make a legible letter than curves do?

Are the only usable fonts the Cam-Bam defaults or does the component access Rhinos/the Windows font directory? I agree that Text Objects are not a good solution in grasshopper, but would like to be able to use my own single stroke font.

Thanks again,

Jackson
