This library is an ongoing personal project to create a PUBLIC DOMAIN collection of files to be used in CAD (Computer Aided Drafting) systems as “insert blocks”. Current count (04 July 2013) is about 3,800 DWG blocks. Most of these DWG files were created with the software DRAFTSIGHT: a FREE software package produced by Dassault Systèmes available for Windows, Linux and Mac operating systems. Anyone may download, install and use this software (see the web links at the bottom of this page). There is simple yearly email activation. DraftSight is a two dimensional CAD system with some 3D (Three Dimensional) capabilities. This software is very similar to the previous generation of the classic AutoCad software produced by Autodesk. These blocks (“.dwg” files) should be compatible with the following CAD software (among others): Draftsight BricsCAD Ares Commander IntelliCAD ProgeCAD Corel CAD TurboCAD AutoCAD ViaCAD
Note that Draftsight can be used to export these DWG files to other formats such as SVG, EMF, EPS, JPG, PNG or PDF for use in other software such as: GIMP, PhotoShop, Corel Draw, Paint.Net or Illustrator. |
|
All DWG distribution files (with a few exceptions) are archives compressed with the open source file archiver “7-ZIP” using the LZMA2 compression format. These archives achieve an order of magnitude greater compression for DWG files than the previous used ZIP archive format. If your operating system does not already have it then FREE software for decompressing the 7z files can be found at the URL: http://www.7-zip.org/ |

This section is the basic Library documentation. The PDF document covers basic file/block name conventions, archive format and revision history (boring details). There is also a spreadsheet with the dimensions used to create the fastener drawings. Note: some sections include their own documentation file specific to that section. July 2019: Madison Electric Junction Boxes and Alumicon KeyWild_Cad_Library_20130723.pdf (243 KB) Fastener_Dimensions.xlsx (256 KB) |

I wanted to find out if one could fit some items into a standard 3 gang switch box but dimensions were difficult to come by. So I ordered one and drew an outline. Turns out what I wanted to put in there would not fit … so I ordered a five gang box. Amazon of course shipped me a six gang box. So I made drawings of those as well. Perhaps someone will find them useful (PNG, PDF and DWG files).

This section has three dimensional DWG blocks Hex Head Cap Screws (Bolts) and Nuts. These models are implemented as a single multi-segmented “polymesh” for each object. Certain details can be included or excluded: fully formed helical threads, washer face, head radius.
Hex Head 3D Documentation: (1.3 MB) This is the PDF documentation for this section of the CAD library. It is also the help file used by the “KeyWild Bolt 3D bolt Generator” available below.
Hex Head 3D Model Sampler: (781KB) This archive is a “sampler” of 1/2 inch nominal diameter fasteners at different level of complexity. It also includes a couple of the script files. Be forewarned that 240 segment part can really drag down your computer system (but they look great!). KeyWild_Cad_Library_HexHead_3D_Sample_20130625.7z
Hex Head 3D Models – DWG files: (4 MB) This archive is a collection of 700 DWG models. These are all Hex Head, Washer Face with Radiuses under the heads. They are the least complex model (24 segments) in UNC and UNF threads. In addition a full set of “unthreaded” models and all four forms of nuts are included. The nominal diameters are: 1/4, 5/16, 3/8, 7/16, 1/2, 5/8, 9/16, 3/4, 7/8 and 1 inch with lengths from 1/2 to 12 inches in 1/2 inch increments. This archive is for those that do not want to go to the trouble of creating their own 3D library or for others to use as a starting point. KeyWild_Cad_Library_HexHead_3D_DwgFiles_20130625.7z
Keywild 3D Bolt Generator Program: (61 KB) This archive is the software that was used to create the 3D models. The logistics of including a block for every possible size, option and level of detail is staggering. Instead I am making the software available. You can use it interactively to create models that are not included in the library or using this software you can build your own 3D model library with models designed to your own specifications. The archive includes the command line batch files that were used to create library blocks above. I run this on Windows7 X64 without any problems. Operation under Windows8 might be questionable (as well as why you have Windows8). You will need the PDF documentation (above) as well (it is used as the help file). KeyWild_Cad_Library_HexHead-3D_Program_20130625.zip
Keywild 3D Bolt Generator Program (with VB6 setup): (1.5 MB) This is the same software with the VB6 MS runtime setup. (You only need this if you do not already have the VB6 runtime). KeyWild_Cad_Library_HexHead_3D_Program(RT)_20130627.zip

Scaled dimensions are shown in red. Each archive contains the original drawing files, dimensioned PNG file, rendered 3D model as a PNG file (with transparency) and the cute sheet from the PDF specifications.

Dwg2Png: When working with CAD programs that utilize the DWG file format it is sometimes desired to convert a group of the CAD files into another graphic format such PNG, SVG or PDF. This may be because these formats are required for documentation, menu systems or are to be used on web sites. Converting each DWG file using the built in functions and menu system is adequate for a single file but quickly becomes tiresome time consuming task for multiple files. The Dwg2Png process automates this task allowing one to utilize their time more efficiently. This process is not limited to converting DWG files to PNG files. With three simple files this methodology may be used as the basis to automate processing an entire directory structure or a single file for such things as printing, backups, distribution or data extraction. This would of course require that someone develop the appropriate CAD script and/or command files(s) for the target process. It is a simple matter to do this for exporting PNG, JPG, PDF, DXF, SVG and EMF file formats. Tasks such as printing could be a tad more challenging. The archive contains two command files, one script file, five simple DWG files and a PDF file that fully documents the process. Dwg2Png.zip: (631 KB) |
