I have an issue with the scaling of my designs made in auto cad 2017 imported into app.glowforge.com . I have been able to cut this product by convert my DXF Files from Auto Cad to an SVG File type using Convertio.com. When I import he project, the files imports a different size. Why is this?
My question is what would allow me to draw to size in Auto Cad and export or convert in to a cutting file? Then when I open up the file the size of the parts dont change?
This is almost always caused by improper settings during conversion, esp. resolution (DPI), and the evil āresponsiveā tag set to true. As suggested above, thereās been a great deal of discussion on this topic:
I think MeshMixer will take DXF in and output SVG. Iām pretty sure itās still free. And itās now owned by Autodesk so the odds are itāll have good compatibility with DXF.
Iām sorry that you ran into trouble when trying to convert your DXF files to SVG. I would recommend looking into Inkscape. Inkscape is an open-source graphics editor available for free online.
You can find some first-steps on how to install the software and where to look for tutorials on our support page. Here is a link to the topic: Introducing Inkscape
Inkscape has the ability to import DXF files and then you can manually set the scale factor. I hope this information helps you and your students to get up and printing with your designs! Please let me know how it goes.
Just save them to PDF right out of AutoCAD. They are saved as a vector format and you can import them right into GFUI. I do this with my CAD software and there is another user who has found this works great and has solved some of his issues also.
You may have to set up your PDF export settings to ensure they donāt scale to fit the sheet, but it should only need to be done once.
First you have to make sure the AutoCAD file has units defined since a new blank drawing has no units by default. Then other programs will be able to read the scaling in the DXF file.
I use Inkscape (Open Source) to open DXFās that Iāve exported from Fusion 360.
In Fusion I set the file units to millimeters then in Inkscape I use a manual scale factor of 1, because the default in Inkscape is also millimeters.
Try saving your DXF as a PDF from your creation program. I suspect you will avoid the need for the intermediate steps unless you are using them to add additional material.
Nope, the only way Fusion will create a PDF file is if you set up drawing views of a 3D model first. Itās not difficult to do but often I wonāt even make a 3D model, and just work off 2D parametric sketches. Cant make a drawing view, and thus no PDF option, from 2D sketches.
If operation steps need to be altered it still needs to go into another program for that because Fusion doesnt differentiate linetypes, colors, etc.
Itās been a little while since Iāve seen any replies on this thread so Iām going to close it. If you still need help with this please either start a new thread or email support@glowforge.com.
