Hi Thom,

Thank you for your quick respons. It works!
With exploding the groups I got rid of the two levels.

With kind regards,

Frank

Enjoy spring!

Hi Thom,

Thank you for your quick respons.
I indeed did not want to create a two level nested group.
Is it easy for you to tell me how I got rid of one of the two levels?

With kind regards, Frank

Hi all,

Embarrassing simple questions (I think):

1. The code underneath gives the message "bbx1 deleted!"
   What is happening and how do I prevent it from being deleted?
2. The code underneath gives alse the message "bbx2 is not a manifold"
   What is happening and how do I make it a manifold?
   ( I want to learn about boolean solid operations like union etc,... )

With kind regards,

Frank Brugman
