Oh this is nice. I’ve been using @Helvetosaur scripts for a while and I’m struggling to implement different export options. It looks as this new approach could solve all my problems. So for exporting *.dxf, you’d also have to use the File.DwgWriteOptions?
Yes, File.DwgWriteOptions will do both DWG and DXF. It is keyed off the file extension given.
import scriptcontext
import Rhino
import os
if scriptcontext.doc is not None:
options = Rhino.FileIO.FileDwgWriteOptions()
options.UseLWPolylines = True
options.Version = Rhino.FileIO.FileDwgWriteOptions.AutocadVersion.Acad2000
options_dictionary = options.ToDictionary()
path = os.path.expanduser("~/Desktop/sample_py.dxf")
success = scriptcontext.doc.Export(path, options_dictionary)
if success:
print("Successfully exported sample_py.dxf")
else:
print("Error while trying to export sample_py.dxf")
No presets. Set the invidual mesh properties.
This is how I set the meshing options recently:
scheme = rs.GetString("select mesh settings", defaultString=None, strings=('quick', 'medium', 'fine'))
print(scheme)
if scheme == 'quick':
rs.Command("-_Export "+path+" _Enter _Enter", False)
if scheme == 'medium':
rs.Command("-_Export "+path+" _Enter d a a 0 s 0 d 0.1 g 4 m 0 i 0.02 u 4 _Enter _Enter", False)
if scheme == 'fine':
rs.Command("-_Export "+path+" _Enter d a a 0 s 0 d 0.005 g 4 m 0 i 0.02 u 4 _Enter _Enter", False)
So, the code looks like this for the medium above:
import scriptcontext
import Rhino
import os
if scriptcontext.doc is not None:
meshop: Rhino.Geometry.MeshingParameters = Rhino.Geometry.MeshingParameters()
meshop.RefineAngleInDegrees = 0
meshop.GridAspectRatio = 0
meshop.Tolerance = 0.1
meshop.GridMinCount = 4
meshop.MinimumEdgeLength = 0.0001
meshop.RefineGrid = True
options = Rhino.FileIO.FileStlWriteOptions()
options.BinaryFile = False
options.ExportOpenObjects = True
options.MeshingParameters = meshop
options_dictionary = options.ToDictionary()
path = os.path.expanduser("~/Desktop/sample_py.stl")
success = scriptcontext.doc.Export(path, options_dictionary)
if success:
print("Successfully exported sample.stl")
else:
print("Error while trying to export sample.stl")
This is a quick sample. I expect creating preset classes for schemes would make the most sense in this case.
The Mesh parameters class also comes with a lot of different properties and constructors: https://developer.rhino3d.com/api/rhinocommon/rhino.geometry.meshingparameters#properties
The orginal request, coded up in Rhino 8 this might look like this:
#! python3
import scriptcontext
import Rhino
import os
meshop: Rhino.Geometry.MeshingParameters = Rhino.Geometry.MeshingParameters()
meshop.RefineAngleInDegrees = 0
meshop.GridAspectRatio = 0
meshop.Tolerance = 0.1
meshop.GridMinCount = 4
meshop.MinimumEdgeLength = 0.0001
meshop.RefineGrid = True
def writeselectedstl(filename):
if scriptcontext.doc is not None:
options = Rhino.FileIO.FileStlWriteOptions()
options.BinaryFile = False
options.ExportOpenObjects = True
options.MeshingParameters = meshop
options_dictionary = options.ToDictionary()
path = os.path.expanduser(filename)
success = scriptcontext.doc.ExportSelected(path, options_dictionary)
if success:
print("Successfully exported sample.stl")
else:
print("Error while trying to export sample.stl")
def fun():
cdoc = Rhino.RhinoDoc.ActiveDoc
cnt = 0
for rObj in cdoc.Objects:
if rObj.IsNormal and rObj.IsMeshable:
cnt += 1
cdoc.Objects.Select(rObj.Id,True)
obj = rObj.Select
writeselectedstl(f'~/Desktop/sample_py{cnt}.stl')
cdoc.Objects.UnselectAll()
fun()
I think that line should read:
meshop=Rhino.Geometry.MeshingParameters()
filepath = f'~/Downloads/export/sample_py{cnt}.stl'
Somehow this f-string doesn’t work…
I replaced it with the following line:
filepath = '~/Downloads/export/sample_py' + str(cnt) + '.stl'
Which script editor is being used? This is a Python type hint syntax that is supported in the Rhino 8 ScriptEditor. It works well to give the Editor and Runtime engine more information about what is expected.
Python’s string shortcuts are so varied.
The F-string syntax was introduced in Python 3.6. It does work in Rhino 8 and CPython 3.9.
I’m pretty sure my Rhino is up to date.

Yes Rhino is up to date. Which Script Editor is being used?
I am in 8.8, but I did not think this would have been any part of a change.
Looing at Tools > Advanced > Language Status panel will show what is running:
Looks good. Can you try this one:
Fstring test.gh (6.0 KB)
But that syntax is working in that case.
Then:
Why does that version not work?
