Rendering a DXF file
0. Consider validating the DXF file before rendering it. This can be done by using the QSketchMetric Validator. See <Validating a parameterized DXF file validator> for more information.
If don’t have already, create a
ezdxf.document.Drawing
object to which the renderer will render:from ezdxf import new output_dxf = new()
Warning
Remember to make sure that the output and input DXF files are configured in the same units. If not, you can change the units of the output DXF file by:
output_dxf.units = units.MM
ezdxf by default uses meters as the unit of measurement.
(Optional) Define the variables that are described in
---- build in -----
section of MTEXT entity:variables = {'variable_name': 100}
Define the path to the parametrized DXF file:
path = 'how_to_guide.dxf'
(Optional) Define an offset for the rendered entities:
offset = (50, 50)
Render the file:
from ezdxf import new output_dxf = new() output_dxf.units = units.MM path = 'how_to_guide.dxf' # Optional variables = {'variable_name': 100} offset = (50, 50) renderer = Renderer( path, output_dxf, variables=variables, offset=offset ) rendered_points = renderer.render()
Note
qsketchmetric.renderer.Renderer.render()
method renders parametric DXF on to the output_dxf and returns
rendered points from VIRTUAL_LAYER as a Dictionary
