3D Orbit allows to rotate the drawing the way you need, provides you with a set of standard orthogonal and isometric views.
Quick Access Panel: 
Ribbon: Viewer -> Position -> 3D Orbit
Menu: CAD files -> 3D Orbit
It switches the program to the mode of 3D display. The option 3D Orbit is available for CAD format files. The green circle around the drawing shows that the 3D Orbit tool is on. Use the mouse to rotate the drawing the way you need. Rotation is fulfilled with the help of the left mouse button. Depending on the position of the cursor relative to the 3D Orbit axis, the image can be rotated in the three axes simultaneously or relative to one of them.
Rotation along the X axis
To rotate along the X axis the mouse cursor must be pointed at one of the vertical markers of the 3D Orbit axis and holding the left mouse button pressed fulfill the rotation.
Rotation along the Y axis
To rotate along the Y axis the mouse cursor must be pointed at one of the horizontal markers of the 3D Orbit axis and holding the left mouse button pressed fulfill the rotation.
Rotation along the Z axis
To rotate along the Z axis the mouse cursor must be pointed outside 3D Orbit. After the cursor changes its form fulfill the rotation holding the left mouse button pressed.
Rotation in all the planes
Rotation in all the planes is possible when the cursor is located inside the 3D Orbit borders. After the cursor changes its form fulfill the rotation holding the left mouse button pressed.
