I have read about Early Binding but I hadn't tested the line that you reference: acad= win32com.client.gencache.EnsureDispatch("AutoCAD.Application")
For my surprise, if I replace line: acad= win32com.client.Dispatch("AutoCAD.Application") for the line: acad= win32com.client.gencache.EnsureDispatch("AutoCAD.Application") I have an error about a missing attribute in the line: M.append(objeto.InsertionPoint) The problem here is that if now I go back to use the line: acad= win32com.client.Dispatch("AutoCAD.Application") Now pywin32 brokes and I have always the same error in line: M.append(objeto.InsertionPoint) I need to reinstall pywin32 in order to repair the problem. 2012/5/8 Tim Roberts <t...@probo.com> > DANIEL POSE wrote: > > Hello, > > > > I am writing code to program AutoCAD access from Python using pywin32. > > When I need to work with a high number of AutoCAD objects, it is > > faster to use vba than python. > > Are there some way to speed up python code in order to work faster > > with AutoCAD elements? > > For example in the next code when I work with 512 AutoCAD blocks: > > ... > > > > The output for the code is the following: > > > > M_dimension= 512 > > R_dimension= 262144 > > t_block1= 4.25343304805 > > t_block2= 3.88635510938 > > t_block3= 0.487477319045 > > > > > > Then it is faster to work with R than M, even though R is bigger. > > > > I hope that's not a surprise to you.
