I think the moral of the story is vinyl cutters make mediocre pen plotters and Inkscape isn’t a great tool for HPGL.
At some point in the process one of them shits the bed and and draws a line right through the drawing.
Dashed lines also don’t work; I _think_ HPGL has a line type description feature, so maybe it’s the plotter just not accepting it.
On the plus side, I (sort of) finally got HPGL out of OSX Inkscape by rolling back to v1.3.

I wish I could buy a legit copy of AutoCAD R14 or 2000. That’s all I’d really need for this.

A patron asked our makerspace to design and CNC mill a replica of the Gemeente-Energiebedrijf sign found all over Amsterdam. They brought us a screenshot of a stock photo and some 6mm thick aluminum to cut it out from. Here's a first rough draft, CAD/CAM in #FreeCAD and milled in a #Snapmaker Artisan. I'm a novice at this stuff, you can probably tell from the results lol, but the next one will (hopefully) be better!

A photo of a shiny metal sign on a faux wood table, taken from directly above. It's vaguely pizza slice shaped, except the part that would be the crust is wider than the rest of the slice. It has a raised outer border, with screw holes at each rounded corner. There are raised letters spelling out "G E B" in the pizza crust area, and below that, the rest of it is taken up by a raised stylized lightning bolt. The very bottom tip seems to be jaggedly broken off.

A photo of a painted metal sign with no background, taken from directly above. It's vaguely pizza slice shaped, except the part that would be the crust is wider than the rest of the slice. It has a grey raised outer border, with rivets at each rounded corner. There are raised orange letters spelling out "G E B" in the pizza crust area, and below that, the rest of it is taken up by a raised stylized orange lightning bolt. The inset area between all the other features is black. All of the paint is very cracked and worn.

Just out of curiosity, what kind of workflows do you #freecad or other CAD package users have for simple stuff you need to model for 3D printing or CNC'ing?

I start with a crude Post-It note version and try to get all the measurements in that phase, so when I get to the good part, I can just keep on drawing without killing the flow.

A post-it note it a simple drawing of a part, with all the measurements written around it.

anyone know of a 3d print model for something designed to attach to a roll of flat material (like, paper/film/etc) for cutting it into rectangles? like, something with a straight guide and a little attached razor blade and such

Re: #3dprinting & #3dDesign

I've become ... 'better ' at it, but one of the core things I'm missing is how folks do design when it needs to work with other complex parts.
For example; My #3dprinter is basically a custom component at this point. I had to design the sled to use with the rails, every component outside of the bed-base and the extrusion frame is custom or customized.

I'm looking at making a big upgrade to the hot end but nobody makes my part, and I need a cooling solution. So how do I design a fan/duct system that mounts to my hot end mount, fits all the pieces and is the right length?

It seems incredibly daunting to have to #CAD up the entire assembly from scratch. But other folks do this... Somehow? If I look for cooling solutions on any print-sharing website there are thousands of them.

What am I missing here? 🙁

Finally starting to get the hang of Fusion 360. Designed one part, modified a second one and succesfully joined them. Printing now.
Apart from the permanent frustration caused by me not knowing how to CAD, I actually like working with Fusion. I will give FreeCAD a chance but I'm tempted to figure out how to run Fusion on Linux in my ongoing fuck Windows migration process. Might be easier than the VR sound problem...

“If you've ever maintained the same piece of software for more than a couple years, you'll understand how hard it is to pivot already-finished #tools to learn from #ParadigmShifts in the industry. Even if you try your hardest, it's very easy for the old way of doing things to be woven throughout your #codebase as assumptions.

As #JessFrazlle mentioned in her first post, this is why most #CAD software is not extensible. Most of them have assumptions about software that were true in 1990 but aren't anymore: that the #internet doesn't exist; that #GPUs don't exist; that clicking is easier than typing for most user interactions”
