The "JEEP" Fire Pit

Thanks !

What thickness do you fellows cut pits like this out of? 10ga? 3/16?

I would expect 10 ga. or thicker. I think it all depends on if it will be more ornamental in nature or will see much actual use.

This looks awesome! I can not wait to try and cut this to see how it comes out. Thanks for sharing!

Question on this file, I was expecting to see all of the circles and arcs as just that, but when I got it for instance the headlight instead of being a circle is defined by 100s of small line segments. Did I do something wrong, or does my AutoCAD LT 2017 do something different with the file? I didn’t try it in Fusion 360 yet.

I don't think you did anything wrong. I see the same thing when I open it with Inkscape as well as Design Edge. I think this is just a result of the software the OP is using for his vector file creation. But it should still cut fine.

As an example - TMCad allows for export of dxf files in four different formats.

Polyarc, Polyline, or Spline would generally be preferred over the Line format. Perhaps Tom Caudle will have some thoughts on this as well.

Thanks for the quick reply David. Yeah, I myself always try to stick with poly lines. We learned different ways.

Another thing with many line segments vs poly lines is in your CNC program each line segment is another line of g-code, so this file will get very large quickly. Where as if you have a circle the g-code is based on the center, diameter, etc. it ends up making a much smaller g-code file. My basic understanding is you want as few line segments or vertexes as necessary to define what you’re cutting so the g-code file isn’t unnecessarily large.
