DinØ,
Thanks for the data. I think the problem is a very simple one and perhaps easily reproduced.
The problem as you experienced it actually ONLY happened to me here when I attempted to ADD the imported points to a Group and then it would hang. I tried an AUDIT and believed that this had resolved it:
Auditing Tables
Auditing Entities Pass 1
Pass 1 700 objects auditedAeccDbClassNode(407) was repaired.
Pass 1 4400 objects audited
Auditing Entities Pass 2
Pass 2 700 objects auditedAeccDbClassNode(407) was repaired.
Pass 2 4400 objects audited
Auditing Blocks
45 Blocks audited
Total errors found 12 fixed 12No this did not solve it.
I then created a new DWT from your 2008 Template, and the drawing was 'converted' to 2009 on the way in even though this is supposed to be the same version? Problem STILL existed. Then the Light came on, in your Point Groups you have TWO (2) _All Points Groups and one of them is or was locked. Unlocking this group solves the problem. Also it is highly suggested that you have only one _All Points groups in your file.
The above is why I suggest that a team of at least TWO users work together on Standards and Styles.
(The above is suggested only in those cases where the two(2) users can work together without throttling each other, or biting, kicking, scratching, screaming, and or throwing objects)
