I thought that this example showed how delightfully simple it is to access ANY module from the huge NopSCADLib library. IOW, enter that single include and a module (such as 'screw') with its appropriate parameters. https://www.dropbox.com/s/g8dvbq7iwfvdwgz/NopSCADLib-UsageTests-1.jpg?raw=1 <https://www.dropbox.com/s/g8dvbq7iwfvdwgz/NopSCADLib-UsageTests-1.jpg?raw=1> <http://forum.openscad.org/file/t3184/NopSCADLib-UsageTests-1.jpg> Promisingly, this indeed proved correct for the three other examples I went on to identify yesterday: M3_grub_screw M3_pan_screw M3_dome_screw All those, and the original M3_cap_screw example that Nophead gave me work fine. However, I'm presumably not using the right part of the extensive documentation, as those three took me a long time to find. Is there anywhere showing an example of every module, its parameters and typical result please? For example, even staying within the realm of screws/bolts/threads, where can I find find line 5 equivalents for ANY module? For example, an M4 countersunk self-tapping screw (not a bolt)? An M8 pan head nut and bolt? Etc. There's a daunting amount of material in the library and I'm keen to use it effectively! Hopefully it's not still a navigational/addressing issue? As my screenshot shows, while NopSCADLib is in C:\Users\terry\Dropbox\3D Printer\OpenSCAD\LIBRARIES\, my projects {'loaded designs' as OpenSCAD calls them) are in various locations within C:\Users\terry\Dropbox\3D Printer. -- Sent from: http://forum.openscad.org/

The readme on github has a section for each file of the library showing all the available functions, modules and objects, their parameters and descriptions. It shows a picture of all the objects and has a link to the code that draws them, which is a simple example of code to use the modules. It also shows all the module invocations for all the objects drawn. I don't think there is such a thing as a M4 self-tapping screw is there? I think self tappers use imperial screw gauges. There isn't an M8 pan screw but there is an M6 pan screw. There is also a link to screws.scad, where all the objects are defined https://github.com/nophead/NopSCADlib/blob/master/vitamins/screws.scad#L93, so you should be able to work out how to make an M8 pan screw by defining a new object. There is no distinction between screws and bolts as it depends on how you use them, not what they are. For example if you screw into a solid metal then it is a machine screw but if you put a nut on it it can be called a bolt, so everything is a screw in the library.

It is simply the long readme on the project landing page, i.e. https://github.com/nophead/NopSCADlib. If you scroll down past the picture there is a table of contents that lets you jump to any section, but it is all on that one very long page. It is automatically generated from the markdown comments in the code. > > *I don't think there is such a thing as a M4 self-tapping screw is there? > I think self tappers use imperial screw gauges.* > > I'm sure imperial are more prevalent but there are plenty of metrics. 25 > pages of them at Farnell for example: > > https://uk.farnell.com/c/fasteners-mechanical/fasteners-fixings/screws-bolts/self-tapping-screws?thread-size-metric=m3 I stand corrected. I didn't know they were referred to as M3, etc, when they are not machine threads. I have never bought any.

To add a new screw you don't need to edit the library. Just copy the line that is the M6 version and change the dimensions by finding an online drawing or measuring one. You can put it on your own file somewhere above where you pass it to screw(). > *There is no distinction between screws and bolts as it depends on how you > use them, not what they are.
