Lasercutter

Liebe Kollegen,


ein äußersts niedliches Hobby: Modelle in Geogebra entwerfen, mit Lasercutter ausschneiden lassen, zusammensetzen. Leider hat es nicht zuverlässig geklappt. Mein Laser-Anbieter bevorzugt DXF Dateien. In diesem Format kann ich aus Geogebra aber nicht exportieren. Mit einer kleinen Datei hat es mit EPS funktioniert. Eine größere Datei, bei der ich gleiche Einzelteile vervielfältigt habe, ließ sich aber nicht Lasern. Deshalb bin ich jetzt auf Inkscape ausgewichen. Mit den Vektor PDFs aus diesem Programm klappt es einigermaßen. Lieber würde ich aber mit Geogebra konstruieren.

Gibt es eine zuverlässige Methode, Geogebra Dateien so zu exportieren, dass übliche Lasercutter sie lesen können?

I suggest you try the SVG export in GeoGebra Classic 6 (you can import that to Inkscape etc)

Thanks for the advice. I tried to open a SVG Export in Inkskape. It's possible, but Inkskape seems to be only a pixel grafik. The lines cant be moved any more. The lasercutter needs vector information. So I doubt that it can work with this information. There's now document type that should work for a laser cutter direktly?

SVG is vector not pixel - it sounds like you are doing something wrong somewhere. Please post the .ggb and .svg files

Seems like I'm getting closer. Yesterday I didn't realise that Inkscape took the Geogebra-Symbols for dots as cirles. Since I removed the Dots, I can grab the lines! Progress!


Still the procedure is a bit tedious. I only need Inkskape, because the laser shop could work with the pdf fils from this program. Wheras the pdf's direktly from Geogebra didn't work. The shop oner sayed he needs vektor pdfs. Seemingly Geogebra produces Pixel pdf's?! Or could I influence that?


Have a merry time

No, GeoGebra exports vector PDFs not pixel


PDF export is better in GeoGebra Classic 6 but also worth trying GeoGebra Classic 5 if you haven't tried that. Merry Christmas!

Hallo, happy new year!


I'm still struggling. I designed the parts in Geogebra. I need 8 different parts that took me nearly 500 konstruktion steps. At the end the program didn't run smoothly any more. I need to copy one of the parts 20 times. I'm afraid the the programm woudn't cope with that amount of objects.


So I decided to use a differnt program to multiply the parts, exported the file as svg and opend it in inkskape. But Inkscape doesn't work in the usual way. I can mark only individual lines no objekts. I cant transform the lines to paths. So I cant mark any of the parts to copy and past.


It seems not to be possible to add the svg file. So I can only send the ggb file. Still I would be very thankful for advice.

How's this? https://test.geogebra.org/~...


I've put each object in a different layer and exported from GeoGebra Classic 5 - so each object should be grouped I hope

Also you could try Polyline() to draw the connected segments as one object in the SVG https://wiki.geogebra.org/e...

Thanks for your help!

To be honest, I suppose I'm a difficult case. If I click to the link you sent, a window with the objects I've drawn opens. But I dont see a possibility to influence the picture, nor to load it down, so I could open it in Inkscape. But never mind, I found a possibility to form objekts out of the lines in Inkscape. For the moment I'm quite happy, so you needn't butter any more. Thank you again!

Why you don't use tool like 123D Design it will be more useful to trace complex object to print or laser cut them ?
