![]() ![]() 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 Edit 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. Imports a file for use in the current OpenSCAD model. *.stl) to browse to additional file types. The file type filter of the Open File dialog may show only OpenSCAD files, but file name can be replaced with a wildcard (e.g. The File > Open command may be used to insert this command. Importing is achieved by the import() command. If I've got some time after work if you upload the STL somewhere, I can give it a look over?Įrrors: 129 border edges, 1 flipped triangle, 18 holes, and 20 separate shells.Import Modules Edit The text in its current form is incomplete. run one after the other removes internal faces, for example when two cubes are touching each other) "Color model for polygon visibility", then "Remove marked polygons" (something like those names). and it doesn't explain what they are unless you read the instructions. Meshlab can do a lot too - normal fixes, holes, zero area polygons, but you fix things by combining the MANY filters and processes in its drop-down menu's. (Bad people use a local copy of Autodesk Netfabb Ultimate from a pirate site, making an account and going online is the legal way to do it)Īlso Meshmixer can fix a few simple problems - (holes and normals are its strong point) (Just make one for the purpose of cleaning and fixing models!) #OPENSCAD STL FREE#You need to make a free Adobe login to use it. Try putting the model through this site, I've had some very good results with it: They need fixing before bringing the STL into OpenSCAD Like pushing two pieces of paper together they'll look connected, but they aren't.)Īny or all of these issues will kill the build in OpenSCAD. (if two triangles are next to each other, but DON'T connect up to the SAME end points, they'll look joined, but there'll be a zero area hole between them. The model's got problems, definitely one or more of these: 1: HolesĦ: Zero area polygons (2 or more points are in the same place)ħ: Zero area holes. ![]()
