My past experiences in art tell me that we naturally find symmetry aesthetically pleasing, but compositionally, we resort to uneven numbers (the rule of thirds, as an example). I find trying to create something that is balanced visually more interesting rather than something symmetrical. (Also, symmetry is hard.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In my first four vessel designs, I opted to extend the asymmetrical design process that I started in &#8220;Precious Shapes.&#8221; An uneven number of sides creates a subtle tension in the piece, and adding the twists created interesting surface texture possibilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">My first four vessels pictured below are actually three. My design approach to these forms was to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Learn how the program worked and how it interpreted the Grasshopper steps<\/li>\n\n\n\n<li>Learn the extent of how much twist a shape can handle<\/li>\n\n\n\n<li>Adjust the shape to account for areas that would fail in a 3d print<\/li>\n\n\n\n<li>Make functional vessel designs<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The second and third shapes are actually the same model, but stretched vertically to increase the angles of the undercuts. The last two shapes are ones that I would like to make slip casting molds from, but there are some design considerations that I need to mull over before I do that. Making a good plaster mold is time-consuming, so I want to make sure that I have a solid design before I commit to that.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Rhino Renders<\/h3>\n\n\n\n<figure

class=\"wp-block-paragraph\">In the design process, I don&#8217;t like to repeat myself unnecessarily. A lot of that mindset comes from my work experience in IT (if you have to do something more than once, put it into a function, write a script, anything to save some time) and as a graphic designer (make a template, branding guideline, Pinterest board). It&#8217;s a pragmatic approach that allows me to save my energy for more important things. In fabrication, a lot of failure comes from the material and not understanding their properties and potential failure points. This is the part of fabricating that I love, though it can often be very frustrating with repeated failures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The parametric design process allows me to programmatically change my design based on my material. If I&#8217;m doing a tension fit laser-cut box, that tension is based on material thickness and the kerf of the laser. Switching from 1\/4 inch birch to 6 mm birch may not sound like a lot&#8211;it&#8217;s 0.35 mm of a difference, if your material has been measured accurately&#8211;but it can be the difference between success and failure.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:25%\">\n<figure class=\"wp-block-image size-full is-resized is-style-default\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_120319.jpg\" alt=\"\" class=\"wp-image-6261\" style=\"object-fit:contain;width:244px;height:244px\" width=\"244\" height=\"244\" \/><figcaption class=\"wp-element-caption\">My old nemesis, filament spool twists.<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:50%\">\n<p class=\"wp-block-paragraph\">Most of my frustrations with this particular project was getting my 3D printer back up and running, a Monoprice Select Mini that I&#8217;ve had for years. It was a lot of remembering how to troubleshoot and repair errors as they popped up. It did also spur me to finally get my other 3d printer back up and running, which has a significantly larger build volume than this little printer does.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the things that I opted to do with my Grasshopper code is to add a function that distributes the radii of the vessel based on the wall thickness and the Fibonacci sequence. I do want to tweak the code to extend the base to match the wall thickness offset. I am coming from an OpenSCAD background, where you basically write a script that builds all of your shapes for you, and I&#8217;m trying to wrap my brain around how Rhino and Grasshopper does things. (I finally found the spot where I can define the precise location where I want an object to be positioned at, so I will consider that a win.) Most 3d slicing software has a vase mode, where it can print things in a single continuous line after building up the base. It does require a solid shape, so I also want to go back and reprint these shapes with some fancier filament and in vase mode.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:25%\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_164124-1024x1024.jpg\" alt=\"\" class=\"wp-image-6264\" srcset=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_164124-1024x1024.jpg 1024w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_164124-300x300.jpg 300w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_164124-150x150.jpg 150w, https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/20230924_164124-768x768.jpg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Three years later, and it still works pretty dang well.<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">One of the advantages of 3d modeling is the ability to iterate upon a design before committing to a manufacturing process or materials, which is one of my main reasons for wanting to learn how to do it. One of the best examples that I can think of is designing rings. I can come up with a fantastic design, but everybody&#8217;s fingers are different sizes. Making ten different ring sizes, all with the same design, by hand, is not an appealing prospect. (I know I could do it, but again, investing energy in more productive areas.) Having a design that can scale appropriately while keeping other design aspects consistent (like a bezel for a stone) would be a great asset to my own art, or helping others doing that for their own art.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Creative Agency and Intent<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If there is anything that I have learned in any creative pursuit, is that you can give a room full of people the same set of criteria and they will all come up with something different, or they all have a different process to get to the same result. We see it all the time in cooking competitions, and more relevant, our class assignments. Our approaches to creativity vary because we ourselves vary. Our experiences and interests shape how we choose to do things, and that&#8217;s where our uniqueness lies. Learning Rhino and Grasshopper is adding another tool to my toolbox, one that I am happy to see how it can integrate into some of my other processes (like metal casting).<\/p>\n\n\n\n<div class=\"wp-block-file\"><a id=\"wp-block-file--media-ccd96e6d-f77d-4daa-a81c-1da38aaa73e2\" href=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/LizCourtsLA2.gh\">LizCourtsLA2<\/a><a href=\"https:\/\/handandmachine.org\/classes\/computational_fabrication\/wp-content\/uploads\/2023\/09\/LizCourtsLA2.gh\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-ccd96e6d-f77d-4daa-a81c-1da38aaa73e2\">Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>It smells like victory.
