Hi there,
I am having problems completing the following instrucción for autoCAD:
Given some DWG and a Base Drawing i need to do the following:
create a new directory including copies of the Base drawing with the name of the other DWGs.
Copy the model space entities from the DWG to the new base DWG with the same name.
I found the command WblockCloneObject() quite interesting to develop the command but i am not able to make it work. From the code below, no error is generated but also no entities have been copied.
I need also to do some copy of the paper space (that is why there is a function called CopyingFromPaperSpace), but that would come later after i have solved this issue.

}everywhere i found use of WblockCloneObject, one of the databases is the one of the current drawing but that is not my case, i need to copy from a closed drawing into another closed drawing, maybe this could be the problem. The object selection from model space is worrking as i have set some dialog to show quantity of collections and it works fine.
I hope some one here could help me solve this problem.
Regards.
