ReMark Posted August 4, 2010 Share Posted August 4, 2010 (edited) For those of you searching for information on how to draw a 3D bolt, 3D screw or 3D threads check out the following links. Ellen Finkelstein’s AutoCAD Tips & Tutorials Tutorial: Draw a 3D threaded bolt http://www.ellenfinkelstein.com/autocadtips/AutoCAD_tips_draw_3d_threaded_bolt.html The tutorial actually covers the creation of a three inch long lag bolt with a fairly large threads per inch setting. Dr. J.D. Mather’s AutoCAD 2007 3D Modeling – Cut Threads (Tutorial 4) http://home.pct.edu/~jmather/content/CAD238/AutoCAD%202007%20Tutorial%204.pdf This is an 11 page tutorial that can be sent right to your printer. It covers the creation of a metric stud (M10x1.5) and nut. It demonstrates how to cut both external and internal threads. Note: Dr. Mather is a frequent contributor (status: Forum Deity) here at CADTutor. Cadalyst magazine, June 1, 2002 by Tony Hotchkiss. Article entitled, “Draw 3D Screw Threads”. http://www.cadalyst.com/cad/autocad/draw-3d-screw-threads-9994 A good resource for those of you using an earlier version of full AutoCAD (like 2000 or even R13) that did not come with a lisp routine for creating a helix. Helix.lsp can be downloaded via a link in this article to the Cadalyst web site. The tutorial does not actually demonstrate how to draw a bolt or a screw like the two previously mentioned tutorials. Another Helix.lsp routine is available here at CADTutor. It was written by forum member and Super Moderator Miklos Fuccaro in November, 2002. The link to download the lisp routine (1.13KB) is available via the following. http://www.cadtutor.net/forum/showthread.php?1396-Helix&highlight=helix.lsp Erhan Toker's "Using Helix and Sweep" for AutoCAD 2007 and higher. Mr. Toker demonstrates the helix and sweep commands in this tutorial for drawing a M10x20 screw. He uses a simple hexagon extrusion for the bolt head which is OK for demonstration purposes but not entirely correct. http://www.dailyautocad.com/2007/10/advanced-solid-modeling-in-autocad-2008.html# This tutorial was found by forum member pippobaudo and was included here on January 19th, 2011.
