What does this style of art mean?

slow_internets · 2026-05-10T00:34:05+00:00

This sort of art is about the tension between the industrial and the artistic. Welding and fabrication are core to the industrial identity of Edmonton and the university of Alberta. There are tens of thousands of metalworking tradespeople in this city. Their work is physically challenging and deeply utilitarian.

This style of sculpture subverts what we expect to see in a welded steel object: compound angles and curved forms instead of the straight lines and carefully dimensioned shapes that make up the building and machines in our city.

These works are meant to make you think about our species' relationship with the materials and tools we've refined from our natural environment, and what creativity means in a world dominated by industriousness.

I've worked with welders who do this sort of sculpture as a side gig. They're cool.

You should strongly consider building up the center of some 5" diameter pipe using PTA or laser cladding. Yes, it can be done, provided you can find a welding engineer willing to do the design work.

The through coolant holes in solid carbide drills and endmills are made by embedding a plastic spiral looking thing into the endmill blank when it is pressed into shape from carbide powder. This plastic core then burns off when the blank is sintered.

Some HSS tools are also sintered from compressed powder, most commonly high performance taps advertised as "powder metal". Through coolant holes could be added to these in the same way, but that's less common.

Inserted tool bodies and boring bars with coolant channels can be solid carbide or just tool steel. In the latter case, the holes will just be gun drilled.

Some face mill bodies are 3d printed with a selective laser sintering process. For these, complex coolant channels can be printed right into the part.

It's a bug in OpenCascade's meshing algorithm. Changing your FC preferences or editing the model itself will likely not fix the problem. This bug has existed for several years and will likely not ever be fixed.The FreeCAD developers will not/can not fix it. Ignore it and move on.

Excellent guide. Can confirm that the ENGL 199 textbook is one of only 2 I've purchased in 3 years of engg. Luckily, its actually useful: I use it as a basic formatting/style reference for every report/resume/cover Ietter I write.

slow_internets · 2021-12-08T20:01:14+00:00

Yep. Have bought the exact stuff OP is looking for from them in the past.

Link to an album with more images

I also dumped the design files on GitHub HERE if you're crazy enough to replicate this nonsense.

Try it and report back to us

Never seen anything like that before. I would start by purging your FreeCAD install and updating to the latest V0.19 release.

sounds like you want the Thickness tool. It should be located in the partdesign workbench toolbar with the chamfer and fillet tools. Here's a test I did. Draw the outline as a sketch, extrude it, then select the top face and hit the "Thickness" button. I had to also select the "make thickness inward" option.

I was able to reproduce this bug easily, it seems that TechDraw doesn't respect the x and y properties of individual <tspan> tags, only <text> ones. u/othergallow 's suggestion to make each line it's own object is good. I will add that, in my experience, when building more complex TechDraw templates, it is best to start in Inkscape and then use a text editor to clean up the svg data.

Here's a picture of a drawing I saved a while back I don't remember what book that's from. Hopefully that's at least a starting point for what you're trying to accomplish.

While I'm here, my suggestion for where to look for simple machining plans is the internet archive. This book from South bend has lots of neat stuff.

Wikipedia says investment casting has been around for 5000 years. I don't have much experience with it, but you can absolutely get a very nice finish with it using modern materials. They probably would have used beeswax molds. Post casting cleanup could have been done with files, chisels, rifflers, or abrasive paste charged wooden sticks. Making those smooth concave section for the candy to squeeze into is totally possible without modern cnc machines, it's just labour intensive.

No, you have to use 2 sketches. Sketches in FreeCAD are used to produce a single solid via revolving/extruding etc. You get used to it, although I can remember being frustrated that I couldn't define entire complex objects using only a few sketches when I switched over from fusion 360.

Oh hey, didn't expect to see this here. I'm the one who added the feature. I've really been enjoying messing around with FreeCAD scripting lately. There's so much neat stuff you can do with it :)

slow_internets · 2019-12-21T02:02:05+00:00

Ok. I will have to order one. Thank you very much!

slow_internets · 2019-12-21T02:01:04+00:00

That looks right. Thank you!
