#!/usr/bin/env python # -*- coding: utf-8 -*- """ Macro to generate screws with FreeCAD. Version 1.4 from 1st of September 2013 Version 1.5 from 23rd of December 2013 Corrected hex-heads above M12 not done. Version 1.6 from 15th of March 2014 Added PySide support Version 1.7 from April 2014 fixed bool type error. (int is not anymore accepted at linux) fixed starting point of real thread at some screw types. Version 1.8 from July 2014 first approach for a faster real thread Version 1.9 / 2.0 July 2015 new calculation of starting point of thread shell-based approach for screw generation added: ISO 14582 Hexalobular socket countersunk head screws, high head ISO 14584 Hexalobular socket raised countersunk head screws ISO 7380-2 Hexagon socket button head screws with collar DIN 967 Cross recessed pan head screws with collar ISO 4032 Hexagon nuts, Style 1 ISO 4033 Hexagon nuts, Style 2 ISO 4035 Hexagon thin nuts, chamfered EN 1661 Hexagon nuts with flange ISO 7094 definitions Plain washers - Extra large series ISO 7092 definitions Plain washers - Small series ISO 7093-1 Plain washer - Large series Screw-tap to drill inner threads in parts with user defined length ScrewMaker can now also used as a python module. The following shows how to generate a screw from a python script: import screw_maker2_0 threadDef = 'M3.5' o = screw_maker2_0.Screw() t = screw_maker2_0.Screw.setThreadType(o,'real') # Creates a Document-Object with label describing the screw d = screw_maker2_0.Screw.createScrew(o, 'ISO1207', threadDef, '20', 'real') # creates a shape in memory t = screw_maker2_0.Screw.setThreadType(o,'real') s = screw_maker1_9d.Screw.makeIso7046(o, 'ISO14582', threadDef, 40.0) Part.show(s) Version 2.1 August 2015 added: ISO 8676 Hexagon head screw with metric fine pitch thread Version 2.2 May 2018 - Extend function "moveScrew" to check for Body and Part. - Add Screw to Part if Body is in Part. - Search for plane support face to get correct orientation - fix failed hex-head Version 2.3 Oct 2018 - fix missing function equal_vertex to do: check ISO7380 usage of rs and rt, actual only rs is used check chamfer angle on hexogon heads and nuts *************************************************************************** * Copyright (c) 2013, 2014, 2015 2018 * * Ulrich Brammer * * * * This file is a supplement to the FreeCAD CAx development system. * * * * This program is free software; you can redistribute it and/or modify * * it under the terms of the GNU Lesser General Public License (LGPL) * * as published by the Free Software Foundation; either version 2 of * * the License, or (at your option) any later version. * * for detail see the LICENCE text file. * * * * This software is distributed in the hope that it will be useful, * * but WITHOUT ANY WARRANTY; without even the implied warranty of * * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
