How to change perspective preview?

After starting the program, or after changing the preview mode, the perspective preview is set with the default settings, the dimension and the viewing angle are not as I need.
Where can it be changed?

You ned to tell us what screen you are using. What version of linuxcnc are you using?

For what ?
I am writing in the "Gmoccapy" section and I ask where the default panoramic preview settings are.
What can not you understand here?

After run program :



After manual change view (by mouse) :



After switch from "P-view" to "Z-view" :



After switch to "P-view" again :



I have got touch screen, and its hard to change view without mouse.

My oversight - I didn't look at the section - only the title.

Is your question pertain to the default zoom of the perspective?
As your first image and second look the same.

This is of course a preview of the same file, and in both cases it is shown correctly.
However, I would like to see a whole workspace at a different angle.
Size and location can be changed with your finger on the monitor, but to rotate the preview you need the right mouse button ...

Ahh you need a selection button to toggle between pan and rotate.

Do you have a keyboard connected - I believe holding the shift key should do it.
