GSoC Proposal: Extended functionality of Rebar Addon

[ebrahim raeyat]

Suggestions are always welcome.

thanks @Suraj Dadral. very thanks. it works well. one note:

in column and beam, it is not common to declare span between rebar except for Stirrups. in slab it is common to tell spans.

Hello @All

The documentation pages for reinforcement drawing and dimensioning are ready:
Reinforcement Drawing: Arch_Rebar_Drawing
Reinforcement Dimensioning: Arch_Rebar_Dimensioning
Reinforcement Drawing and Dimensioning: Arch_Rebar_Drawing_Dimensioning

Looks good. Nice job!

Hi @ebrahim raeyat

Thanks for introducing to the process.
As we are not handling dimensioning based on structure type, so this thing needs to be adjusted by user, which is possible while creating drawing and dimensioning and can also be altered after creating drawing and dimensioning.
In future, we can also have special wrapper functions for different structure types if need arises.

Thanks,

thanks, you are right.

Hi @Suraj,
BTW, it would be great if users could not only specify the span but also the spacing of the rebars in dimensioning text. Something like "%S/(%M-1)". Would this be possible? I think a lot of users would love this feature.

Thanks and regards!

Hi @balrobs

We can add new placeholder like %s for spacing in rebars.
I will implement it soon. For now, created issue here to track this.

Hi @All

Here is update:
1. Create function getRebarShapeSVG() to get rebar shape svg with its dimension.
Sample output:

test_rebar_shape.svg

(1.73 KiB) Downloaded 47 times

test_rebar_shape.png (2.2 KiB) Viewed 1473 times

2. Create function getRebarShapeCutList() to get rebar shape cut list svg.
Sample Output:

test_rebar_shape.svg

(12.91 KiB) Downloaded 63 times

test_rebar_shape.png (10.29 KiB) Viewed 1473 times

How to use:
You can get the latest code from here.

Code: Select all

import importlib
from xml.etree import ElementTree

import Draft
from RebarShapeCutList import RebarShapeCutListfunc

importlib.reload(RebarShapeCutListfunc)

base_rebars = Draft.get_objects_of_type(
    FreeCAD.ActiveDocument.Objects, "RebarShape"
)
arch_rebars = Draft.get_objects_of_type(FreeCAD.ActiveDocument.Objects, "Rebar")

rebars = []
rebars.extend(base_rebars)
rebars.extend(arch_rebars)

rebar_shapes_svg = []
for rebar in rebars:
    rebar_shapes_svg.append(
        RebarShapeCutListfunc.getRebarShapeSVG(rebar, scale=0.1)
    )

print(ElementTree.tostring(rebar_shapes_svg[0], encoding="unicode"))

rebar_shape_cut_list = RebarShapeCutListfunc.getRebarShapeCutList()

output_file = "/home/blank/GSoC20/test_rebar_shape.svg"
with open(output_file, "w") as f:
    f.write(ElementTree.tostring(rebar_shape_cut_list, encoding="unicode"))

- The above functions will work for ArchRebar and Rebar2 objects.
- The length of each edge is calculated as there would be no curves as suggested by @bernd here.

Do we also need to add bent angles in the rebar shape cut list, or will we do it in the bar bending schedule?

Please review and give your suggestions.

Thanks,

Thanks,

Very thanks for your effort, works fine for me. one not:

in my stirrup I gave float point like 357.01 in mm.

Bent angle is part to specify rebar shape. So, I think it should be present in rebar share cut list. But we can skip 90 angle because user can interpret it from rebar shape. Maybe bernd, balrobs and ebrahim tell us better here.

I agree with you @amrit3701, whenever we draw the shape of a rebar and its dimensions, we should specify not only the length of the bended part but also either deltaX and deltaY or its bending angle if not equal to 90°.
BTW maybe at this point it might be useful to think about what the rebar shape cut list and the bar bending schedule we want to generate should look like. I believe that standards in this regard differ from country to country.

Kind regards
