Actually drawing on yourself might not be necessary if you keep track of a datum reference point on your body and the distance from there to each diameter measurement or something like that. You could build the essential object in a parametric package, then export that STL to a mesh editor and play with smoothing the surfaces and pushing and pulling to finish the part.Įither way, you should be able to make something work with some orthogonal pictures of whatever body part to get outlines and a series of diameter measurements along the length at known distances to help define a wireframe. I've never used Blender, but if it works as a mesh/STL editor, then that'll probably be a lot easier for organic type modeling since it might let you push and pull on the triangles and vertices that make up the mesh which usually isn't an option in parametric CAD packages like SW (Fusion does have it with T-splines though).Ī combo of the two is also not a bad idea if you want to make sure things are smooth. Just be forewarned, SW at least frequently made errors when I tried thickening intricate surfaces. This is obviously cumbersome since you might need a lot of sketches to define the object's surface, but once you have the wireframe set up, it's not hard to tweak the initial surface geometry. It worked fairly well, but still came out a little blocky in places because of the way I did it where I couldn't always get SW to make the surface using all the splines at once. Then you just build surfaces from all the splines and thicken them to make solid objects (SW at least lets you define edges of a surface and then interpolates the contours of the actual surface). One of the methods I used to do this in SolidWorks was what you suggested, finding pictures and tracing outlines with splines to make a wireframe model of the object. So, I'll preface I'm only familiar with the functionality available in stuff like SolidWorks, Autodesk Inventor/Fusion, and Materialise Magics/3Matic, but I found that working with surfaces was the best way to get organic shapes (specifically, I made a face, lotus type flowers, and a suit of armor in SolidWorks and do anatomical modeling in Materialise for medical models, usually from CT scans). Ultimately your objective is to define a wireframe with known spacing between the lines, line arclength, and known reference angles for pictures so you can translate that info into CAD appropriately and build surfaces/lofts from a spline wireframe. Here the artist has given the organic shapes of this carcass of beef great expressive power. The shapes of the highlights are also organic. The artist used light to highlight the form and show depth. In this photograph of a real pepper, the gently curving outline of the form is an organic shape. Even the shape of the jar itself is a perfect combination, which is an oval when seen from the side and a circle when seen from above.Įarthenware, polychrome and stone polishing The artist has acheived a perfect balance between the two. The decoration on this ceramic jar illustrates an unusual harmony between geometric and organic shapes. The mouse's funny nose, however, is organic! The circles and squares that make up this sculpture are geometric shapes. Organic shapes are associated with things from the natural world, like plants and animals. Geometric shapes such as circles, triangles or squares have perfect, uniform measurements and don't often appear in nature. Wherever the ends of a continuous line meet, a shape is formed.
