Created attachment 193583 [details] Example for view plane settings Open attached document. It contains left a 3D-Scene with dr3d:vpn="(0 0 1)" and dr3d:vpr="(0 0 10000)". That means, that the view plane normal is parallel to z-axis, the view plane is parallel to the xy-plane. That looks correct. The object on the right side differs only in the view plane settings dr3d:vpn="(1 0 0)" and dr3d:vpr="(10000 0 0)". Here the view plane normal is parallel to the x-axis, which means that the view plane is parallel to the yz-plane. The projection is totally wrong. [A "view plane" is the plane where the projection of the 3D-scene objects are drawn.]
