Hi Pavel,
In Trimble Connect Desktop you can switch the view to orthogonal projection using the button on left side of the 3D view, see below.

In Trimble Connect Mobile you do the same tapping first the gear button on the top right, then select the orthographic projections.
For Trimble Connect Web, I think it's not supporting orthographic views.
Hopefully this helps.
Best regards,
Marko Myllymaa
