Just for conclude the discusion, the solution is win32.client.CastTo() as
Mark said. However, this modification doesn't speed up the code (at least
in my case).
Then, perhaps I need to learn C++ in order to embed python inside AutoCAD
as Dan Glassman said. But, not now...
Here I post the code using CastTo:
<code>
import win32com.client
import time
import string
import random
def nombrealeatorio(size=10, chars=string.ascii_uppercase + string.digits):
'''Esta función crea un nombre aleatorio de 10 caracteres'''
return ''.join(random.choice(chars) for x in range(size))
t1=time.clock()
acad= win32com.client.gencache.EnsureDispatch("AutoCAD.Application")
doc=win32com.client.CastTo(acad,"IAcadApplication")
doc = acad.ActiveDocument
seleccion=win32com.client.CastTo(doc,"IAcadSelectionSets")
seleccion=doc.SelectionSets.Add(nombrealeatorio())
seleccion=win32com.client.CastTo(seleccion,"IAcadSelectionSet")
seleccion.SelectOnScreen()
t2=time.clock()
M=[]
for objeto in seleccion:
objeto=win32com.client.CastTo(objeto, "IAcadBlockReference")
if objeto.ObjectName=='AcDbBlockReference':
M.append(objeto.InsertionPoint)
t3=time.clock()
print 'M_dimension=',len(M)
R=[]
for m in M:
for x in M:
R.append(max(m)+max(x))
print 'R_dimension=',len(R)
t4=time.clock()
t_block1=t2-t1
t_block2=t3-t2
t_block3=t4-t3
print 't_block1=',t_block1
print 't_block2=',t_block2
print 't_block3=',t_block3
print 't_total=',t4-t1
</code>
timing using early-binding:
M_dimension= 512
R_dimension= 262144
t_block1= 3.46952811042
t_block2= 4.81084020455
t_block3= 0.49030086226
t_total= 8.77066917723
timing using late-binding:
M_dimension= 512
R_dimension= 262144
t_block1= 3.20033803179
t_block2= 4.96431445896
t_block3= 0.570101227949
t_total= 8.7347537187
Thank you for this wonderfull mailing list and pywin32.
