pyconcrete

python module for drawing concrete plan details.

it aims to draw such a beam and columns at the end.

It includes BeamType class that itself includes number of Beams class. at present it can draw beamtype shape, beamsize text, dimension lines and axes lines.

Dependencies

• python >= 3.7
• ezdxf

Usage

This example show how you can create BeamType and then export that to dxf file with ezdxf python package for example.

import ezdxf

from pyconcrete.beamtype import beamtype, scalebeamtype, beamtypedxf
from pyconcrete import rebar

y2 = -3.4
left_rebar = rebar.LRebar(count=2, length=132.2, insert=(-11.25, y2))
mid_rebar = rebar.Rebar(count=3, diameter=16, length=310.7, insert=(175, y2))
right_rebar = rebar.LRebar(length=202.75,
                           h_align='right',
                           insert=(641, y2))
tars = [left_rebar, mid_rebar, right_rebar]

y1 = -40 + 3.4
bot_left_rebar = rebar.LRebar(length=122, insert=(-11.25, y1), h_align='left', v_align='bot')
bot_mid_rebar = rebar.Rebar(length=295, insert=(200, y1), v_align='bot')
bot_right_rebar = rebar.LRebar(length=202.75,
                               h_align='right',
                               v_align='bot',
                               insert=(641, y1))
bars = [bot_left_rebar, bot_mid_rebar, bot_right_rebar] 


prop5 = dict(spans_len=[295, 540],
             beams_dimension=[(40, 40), (40, 40)],
             columns_width=dict(
    bot=[45, 45, 40],
    top=[40, 45, 40],),
    stirrups_len=[None, [85, 85]],
    stirrup_at=[(8.5,), (8.5, 17, 8.5)],
    stirrup_size=(8, 10),
    axes_name=[('A', 1), ('B', 1), ('C', 1)],
    top_add_rebars=tars,
    bot_add_rebars=bars)

props = (prop5,)

# scaled beamtype h=75, v=20
new_dwg = ezdxf.readfile('pyconcrete/TEMPLATE.dxf')
msp = new_dwg.modelspace()
h = 75
v = 20
for i, prop in enumerate(props):
    sbt = scalebeamtype.ScaleBeamType(h, v, **prop)
    btdxf = beamtypedxf.BeamTypeDxf(sbt, new_dwg)
    btdxf.to_dxf()
    msp.add_blockref(sbt.uid, (200 / h, i * 130 / v))
new_dwg.saveas('beamtype75.dxf')

output

This is output at peresent, but I'll add styles to seems look better!
