Does anyone know of a commercially available ($$$.$$) library of fasteners per standard/Spec available anywhere? I know you can create them in SW with the library but my supervisor has taks me with finding pre-made fasteners per spec (ANSI/ISO/Etc) with materials and properties all pre-assigned to "eliminate" any human error. I have argued the fact that someone had to create and assign materials to anything we purchase so why not do it in house... It's not the way they want to approach it.. So far I have found this: http://partsolutions.com/ but I wanted to look for others as well. Any input is appreciated.

Hi All, I wrote this software for a CAD application called CorelCAD and I know it works on Graebert's ARES Commander as well, and it should work on Autocad and other LISP based systems, but I'd appreciate it if anyone could check. Maybe most CAD packages come with something like this now? I don't know, but I do know it's a novel way to calculate threads, with very high accuracy, and that conform to ISO standards for thread faces. There are two routines, NUT and BOLT. Bolt calculates external threads, and Nut internal ones. It's not very well written, but it seems bug-free and works well enough. It may require interactivity when it completes it's two "LOFT" commands, but on CorelCAD I use the defaults and just hit enter. Hopefully it might help others who need to create threads. The routines are optimised for 3D printing application, and allow offset on internal threads to allow appropriate clearances, though you can manually set the clearance for external threads by choosing a smaller diameter. When run, it will ask for basepoint, diameter, pitch and indexes ( starts ) - and can create multi-start threads for optical purposes and such. Or perhaps even specialist helical gears. It also creates all threads in the direction of the Z axis. I haven't included reverse gears - but a 3D mirror will create one. The application takes a unique approach to thread creation, generating a longitudinal cross-section in 32 segments and then using LOFT to join them together. It creates each bolt in two halves ( to avoid loft-related issues with torroids ) and them union's them together. It cleans up the final solid part, by masking off at a length and filling in the inside. External threads are created solid and complete, and internal threads are subtracted from another solid. This approach also allows bottoming threads to be easily inserted into solids. Well, I hope you like it It's my first post. I came here some time ago looking for an easy way to make threads, and on not finding one, I wrote my own. I hope it attaches OK isothreads v0.12A.lsp Regards David

Hi All, does anyone know from where I can find drafting standards? I mean handy books or codes about how to: 1- name layers 2- define linetype scales 3- select colors for objects 4- define lineweights for objects 5- define plot styles 6- ... Thanks in advance Mehrdad

Hello. I'm currently a freshman an engineering student at UVM. I'm in a basic autocad class now, and am only using orthographic and isometric views (don't know 3-d autocad yet). For a final project, I am constructing a treehouse using either a pentagon or hexagon shape. What neither I nor my professor can figure out is how one would build this using the iso setting. Using the ellipse to construct this seems to be the right way, but I can still not determine what the angles would be. Also, because it is to be done in isometric view, all the sides of either the polygon or pentagon would have to be true lengths (equal lengths). Any and all help is welcome. Thanks! -Alex

Hi, I need quick help on how I can change the size of the canvas (if thats what it's called, sorry I'm new to inventor) to ISO A4. I created a 3D model then made a dwg out of it now I can't change the canvas size Thanks, LMA
