Created attachment 158235 [details] Document for testing Open attached document. Enable 'Snap to Object Points', that is in View > Snap Guides. The document has two lines. Mark them together. Use the tool 'In 3D Rotation Object' from the toolbar 'Transformations'. You will get a to be transformed rotation axis with two handles. Drag the handles of this axis to the ends of the blue line. Click outside to finish creating the 3D object. Creating a 3D object sets the lines between the segments to "none". To get a better view of the objects click on the scene and then set the line style to "solid". Expected: You get a pink truncated cone with an axis in its center. Actual: A total wrong object. This tool worked in OpenOffice 1.1.5, but was already broken in OpenOffice 2.2. It likely happens with the transition from "goodies" to "basegfx".
