Fasteners workbench based on screw-maker

[shaise]

Regarding task window, agree. need to take a look at it.
Regarding inch fasteners, these can be great upgrade. Should be in a separate code file, though, to not break the integration with ulrich's code.

Great work! When do you think you will start sending PRs to Fasteners workbench?

I want to add a usable compliment of inch based fasteners to the WB before I make a PR. The ToDo list looks something like this:
-2 slotted screw styles
-3ish styles of cross recessed screws
-Nuts, washers, and screwtap/die tools

I also need to dig into the countersinking and diameter matching functionality to make that work with non-metric diameters.

Regarding inch fasteners, these can be great upgrade. Should be in a separate code file, though, to not break the integration with Ulrich's code.

Hmm. currently I have just been adding into the screw_maker file. However, I would say that I have not actually broken the integration with Ulrich's code so far. For example, I was able to bring my fork in line with the recent changes to nut thread generation with minimal effort (see https://github.com/slowinternets/FreeCA ... 8c99b52d32 ). What about the additional types of fasteners (ISO 402X, ISO 7379, DIN 7984) that have already been added on top of the screw_maker macro? At your option, I can rework the changes to interfere less with the macro, but it isn't my preference.

It's so great that you debloated ScrewMaker.py. That is awesome.

Hello folks,

Fastener workbench is great, but I still suffer from being unable to properly dimensioning screws with the Techdraw workbench. The Techdraw workbench simply make Freecad crashing when attempting to render a threaded rod because of the huge amount of details.

When I will be able to get drawings like this with the Fastener workbench?

Also I cannot create partially threaded screws like in the DIN 931 standard.

So, to summarize, what I'm missing more is

1. a "simplified" view (like in the image above) that can be correctly interpreted by Techdraw WB,
2. the option to generate partial threads on screws and rods as well.

At the moment I'm still forced to export PNG images and create fake dimensions by using graphic programs like Gimp and Inkscape...

Setting "thread" to false before using the fastener in tech draw might help.

The drawing is created by TechDraw, so the Fastener Workbench is not responsible for this. This topic has been requested a lot, however, it's not so easy to tackle because TechDraw doesn't really understand the 3D object; it just sees a collection of "edges", it doesn't know that a feature is a "hole" or another thing. It just sees "edges with so and so coordinates" and it displays those.

Further work on this is necessary, and it takes time, as there is only one main TechDraw developer.

No. The result is a simple cylinder. The thread size and length is not depicted.

I understand this.
But what if setting the "thread" property to false produces a simplified view of a solid cylinder surrounded by a "transparent" one depicting the thread "bounding cylinder" made of pure edges and circles? (I hope you understand what I mean.)
In such case Techdraw should have no difficulties to render that.

Also, the possibility to have partially threaded for screws and rods could be really really handful.
A lot of screws have the shank not fully threaded. Also, by using a partially threaded rod, one can build his own screw.

I mean, a property like: "thread length = xxx" (millimiter or inches), measure from the end of the shank.
