Hi

I am trying to import blocks and styles from external DWG. I have no errors, but my code doesn work.

Code - C#: [Select]

Are you missing a tr.commit()?

[Keith Brown]

The tr2.commit() is commented out and there is no commit for the first transaction as MexicanMustard mentioned.  Since there is no tr.commit and since tr2 is nested inside of the first transaction then even if you uncomment the tr2.commit() it will still not do anything.  Nested transactions must be committed in all transactions in order to work properly.

Also when you paste your code into the post if you label it as csharp then it will make it easier to read.
 
So instead of doing this [ code ] do this instead [ code=csharp ].  note: I added extra spaces between brackets so it wouldn't post as code.
