Thank you very much for your support!
I appreciate your fast response.

My Problem was that I added a very big cylinder around my model to simulate "heaven and ground".
I did not figure any other solution for that due to my lack of knowledge ...

So, after removal of this object - everything went back to "fine" again.

Issue - SOLVED...

If there is any hint how to change the "template" or add "Heaven" to my model - thank you in advance

What a thrill to use this software... and a very cool Board by the way!

Greetz and many thanks

Hello All, I am "at the end" and kindly asking for your support.

Since this is my first project pleas forgive me my maybe "novice" question ...

The Problem:
When I Orbit into the model usually it goes into detail by zooming and i will see everything "closer".
New behaviour is: It OPENS the model and there is no chance for me to edit anything or even to see the detail.

What have i done wrong?
Maybe a keycode that I've entered that changes to this behavior?
How can I change this back to normal?

See this short Video that shows my problem.

Also I have added these two images to show what I am trying to explain.

Thank you very much for your assistance!
Sorry if it is already mentioned in the forum - my english is not good enough to find the right words to that issue.

Greetings wiper
