After reading this email, I had an IRC chat with Yorik. Below is the discussion:yorik wrote: ↑Sat Aug 12, 2017 3:34 pm Just tested, works great Amritpal!
Two questions:
1) are circular stirrups always made with such helixes? I suppose there are also conventional stirrups (each stirrup is a separate bar)?
2) Be able to do the vertical bars like @thschrader says would also be nice... Maybe it could be done by extending the straight rebar code (detect if a face is cylindrical, and treat accordingly)?
Amritpal-> yorik, I read your reply on the forum.
Amritpal-> yorik, Your all questions are right but I think now I should complete documentation task.
Amritpa->l what you think?
yorik-> Amritpal: I agree
yorik-> anyway, there will certainly be tasks left, after you finish the GSOC
yorik-> that's how opensource stuff works after all
yorik-> so I think there is no need to try to fix everything
yorik-> follow your own plan first, and if you have time left, try to fix the rest, if not, that will be for after the GSOC (by you or someone else)
Amritpal-> yorik, yes. I will also make documentation as a developer point of view.
yorik-> perfect!
Amritpal-> which helps other to contribute in this project
Regards,

Depends. Usually concrete piles (https://en.wikipedia.org/wiki/Deep_foun ... on_systems) and precasted circular columns uses this helix rebars. Circular columns made on building site sometimes have single cirular stirup rebars instead of a helix rebar. In the regard of helix rebars. They most do have at beginning and at the end some smaller helix spacing like in http://ascelibrary.org/cms/attachment/6 ... igure2.gifyorik wrote: ↑Sat Aug 12, 2017 3:34 pm Just tested, works great Amritpal!

Very good tutorial.cnirbhay wrote: ↑Mon Aug 14, 2017 5:47 pm https://youtu.be/BYQQjEKmx5E
I tried my bit to demonstrate in brief this project.
@cnirbhay, You have missed a little bit magic which is done by custom spacing dialog box.
Read below thread for better understanding.In the dialog box, look carefully at: "n@s (give either n or s)”. As it is saying, you need to provide input either for n or s, but not both because one value automatically determines other.

Re: Dev logs of Rebar Addon for FreeCAD - GSoC project
Thank you, both Amrit and Regis for the kind words.
Today, I tried new possibilities of realistic rebaring in FreeCAD.

Re: Dev logs of Rebar Addon for FreeCAD - GSoC project
I designed the slab first as per the given conditions and with the obtained calculations I gave rebars detailing in FreeCAD using new addon of Amritpal.
Re: Dev logs of Rebar Addon for FreeCAD - GSoC project
just some ideas for later...
1. it is nice that there are individual options for cover (there could also probably be similar for example for left and right anchor length or U shape with different left and right sides lengths...), but this idea is about something else, having all this options makes it more flexible but on the other sides more slow to use since each option has to be changed separately. the idea is to have a check box (or on/off button) next to input fields that would connect all the similar options, for example cover. so by default all cover would be the same and changing one would change all. if there is need to have some different, one would uncheck one or more, as needed, so they would behave individually.
2. there are quite a lot of different standards for rebars and with them different standard rebar shapes, just for example i have compared our current rebar shapes to BS8666-2005, as i can see we should more or less have shape codes 00, 11, 12, 21, 46, 51 and 77... ? no real suggestion here just something to keep in the mind
