When does the Rectangle Tool draw a polygon?

[ThinAirDesigns]

I have a simple rectangle floor slab with four single cavity walls upon it.

While in Top/Plan view, I select the rectangle tool and draw a rectangle by dragging cross corner from outside wall to outside wall.

Lo and behold the drawn object is a Polygon. If I draw next to the slab...rectangle. If I randomly draw in the middle of the slab, it's a rectangle some of the time and a polygon some of the time. If I snap to the corners, it's always a polygon.

Under what conditions is the Retangle Tool supposed to draw a rectangle, and when a polygon?

In the documentation it appears as though the Rectangle tool is to draw *only* rectangles while the Rotated Rectangle Tool draws polygons.

The grid is in a vertical/horizontal configuration(not skewed), and the slab is snapped to the grid.

Thanks

JB,

I can't get the Rectangle tool to draw anything but rectangles--no matter what else I do.

I can convert a rectangle to a polygon after it's drawn. . .but that's not what you're asking.

Have you tried to get this to repeat in a new, clean document?

(Sorry, not really much help.)

Thanks Travis. Yes, I've tried it in a clean document and come up with the same results as you.

I'm mystified.
