Created attachment 170476 [details] document with extruded shape Open attached document. It has a shape, which is extruded. You do not see the side planes because you look in front of it. Select the shape. The "3D-Settings" dialog should open. Look a little bit around, it is likely docked somewhere. If it is really not there, you can open it via View > Toolbars. Open the Direction floater. Click on direction "Extrusion South". Now you can see the shape as if you were a little bit above it. Now click on direction "Extrusion North". Expected: You can see the shape as if you were a little bit below it. It should look the same as "Extrusion South" but vertically mirrored. Observed: Depending on your version, you see no side plane at all or a side plane, which is too short.
The error is a wrong Origin in "case 90" in impl_execute in https://opengrok.libreoffice.org/xref/core/svx/source/toolbars/extrusionbar.cxx Should be "fOriginY = 0.50;" but is "fOriginY = -0.50;" Shapes, which were created with older versions, keep their values until the direction is newly assigned. I don't make it an easy hack, because I need the correct value in my work on export extrusion to pptx.
