Apparently, MI can only create > horizontal or vertical ellipses. I do not think this is possible. There are some rotate-objects utilities around, but they work poorly on this kind of objects. Why? Ellipses, arcs and rectangles are to be considered as decorative map elements, and are not to be used to describe real world objects.

If you want this to happen while editing on screen, make sure the map window setting 'Move duplicate nodes' is turned on in Options > Preferences.

Re: MI: rotated ellipses and moving nodes of polygons
Hi Zoran To 1: As far as I know this is not possible with standard MapInfo function. However there are products that can do that using a rotate object function, such as MapCAD (Non-Earth Projection only, see http://www.tydac.ch/en/workgroup.htm) or MICAD (to be found on http://www.directionsmag.com/tools/Default.asp). Both products are however commercial. To 2: If I understand the question correctly you want to move a node of a polygon and the node of the adjacent polygon "comes along". This is standard MapInfo; under Options / Preferences / Map Window just turn the option "Move Duplicate Nodes" on.
