Make adjustments so that you have a continuous path:.You will need to make this shape a path : Drag the center point down to change the Center of Rotation:.Click on the Selection Toll and press SHIFT+S:.Click on the Rotation tab and change the Angle in per column to 60°:.Click on the Shift Tab and enable Exclude Tile option:.For Symmetry, select P1 and set Rows to 1 and Columns to 6:.Click on the stroke style tab and make the width at least 5 pixels:.Click on fill and the x to have no fill:.Double click on the fill stroke area in the lower left area to open the fill and stroke window:.In this case, it is a shortcut for specifying a -100% shift. This is useful when using the Rotation option to put tiles on a circle. This is useful when one is also scaling the tiles to keep the tile spacing constant.Įxclude tile: The tile width or height is excluded in the calculation of tile spacing. For example, if there was a Shift X of 10%, normally the space between subsequent tiles would be 10%, 20%, 30%, and so on. A random factor can also be added.Įxponent: Changes the exponent factor z so that position of each tile is x (or y) = (1 + "shift")z.Īlternate: The shift alternates between being added and subtracted.Ĭumulate: The previous shift is added to the new shift. Shift X, Shift Y: Adds (or subtracts) to the tile spacing in units of bounding box width and height. The following options are available to add or subtract space between the tiles: With the default parameters, rectangular tiles are arranged so that their Geometric bounding boxes are touching. The Shift tab allows you to vary the spacing between tiles. The OpenSCAD file is fully parametric in case you want to modify these. As the pattern gets larger, the ratio of rhomb1 to rhomb2 tiles will approach the golden ratio (~1.618), because math is awesome. The arcs are formed by thin slices out of the STLs they only go halfway up so you can tell which side is the top.
The arcs also represent the maching rule, so lining up arc segments helps to figure out where pieces can go. It's easy to get stymied (for instance, nothing can attach to certain parts of the black star). I can still print upwards of 30 tiles per hour.Īssemble. This would be a perfect use for an Automated Build Platform, but mine isn't attached right now. Using Multiply, I managed to cram 16 of rhomb1 onto a TOM build platform and 18 of rhomb2 (it helps to use some negative separation with rhomb2). Turn off fill in order to print just the perimeter (this makes them print fast and snap together easily). You’re in for quite a surprise if you expect rectangular coordinates when the polar coordinates box is checked.Print lots of each rhombus. The Function Plotter supports rectangular and polar coordinates. Then I discovered you have to select a rectangle to contain the plot before creating a plot the plotting tools do not create their own rectangles. The first time I tried using these extensions nothing happened. The following dialog shows the settings used to produce the graph above. One is “Function Plotter” and the other is “Parametric Curves.” Both are found under Extensions -> Render. Inkscape provides a couple extensions to include function plots in a drawing.

In a drawing program, it’s obvious how to manipulate a plot as an image. The things I want to do are often possible but require arcane options that I have trouble remembering. But I’ve found it difficult to change the aesthetics of a plot in every mathematical package I’ve used. Mathematical packages make it easy to produce a basic plot with default options.
For example, you might want to include a sine wave in a drawing.Īnother reason is that you may want to have more control (or at least easier control) over your plot. Why would you want to plot a mathematical function using a drawing package like Inkscape rather than a mathematical package like Mathematica or R? One reason is that you may want plot for its visual properties.
