If you want to render the imported STL file later, you have to make sure that the STL file is 'clean'. In the latest version of OpenSCAD, import() is now used for importing both 2D (DXF for extrusion) and 3D (STL) files. Setting it to 10 should work fine for most cases. The convexity of a 3D shape would be determined in a similar way. This image shows a 2D shape with a convexity of 2, as the ray indicated in red intersects with the 2D shape in at most two sections.

Import_dxf(file = 'example009.dxf', layer = 'plate') Linear_extrude(height = 5, center = true, convexity = 10) Read a layer of a 2D DXF file and create a 3D shape. (Windows users must 'escape' the backslashes by writing them doubled, or replace the backslashes with forward slashes.) Import('D:/Documents and Settings/User/My Documents/Gear.stl', convexity=3) The minimum segment length to use when converting circles and arcs to polygons. The minimum angle step to use when converting circles and arcs to polygons. The number of polygon segments to use when converting circles, arcs, and curves to polygons. For DXF import only, specify a specific layer to import. This parameter is needed only for correctly displaying the object in OpenCSG preview mode and has no effect on the polyhedron rendering. The convexity parameter specifies the maximum number of front sides (or back sides) a ray intersecting the object might penetrate.

Note that when using include with a script that uses import(), this is relative to the script doing the include. Other CSG can be imported using include or loaded like an SCAD file, PNG can be imported using surface() Parameters A string containing the path to file.:If the give path is not absolute, it is resolved relative to the importing script. The file extension is used to determine which type. To repair this issue I had to use OpenSCAD to do the union.Imports a file for use in the current OpenSCAD model. I could fix the whole thing with a hot-glue gun, Long story short: The Simplif圓D sliced statue came out of the printer, looked great and the modification fell off immediately. When you are using Simplif圓D, this is an issue. It seems as Cura will fill everything inside the boundaries and assumes that this is the right way to do. (The difference is that a merge will simply put all point/areas into one file, a union will think more about which part is visible and which is not).įun fact: As I am using Cura as my primary slicer, I didn’t notice this mistake. However … When I wanted to create a single shape out of the statue and the modifications I simply mistook merge for union but in the world of points and shapes, this is not the same as a union. My tool of choice was Freecad, and I was able to add the necessary parts to the model. I needed to manipulate the STL-file to add the actual holding parts and some mounting blocks for magnets that will hold the thing in place. Last week, I wanted to create a holder for our shoehorn.īy that time it seemed appropriate that great Cthulhu himself will do us the honor in form of a statue.
