comment Exporting 2D graphics to DXF
In Autocad Rectangle is formed by Closed Polyline and not filled. During the conversion some things may not fit. So, you can try in Mathematica to form Polygon filled instead of rectangle. That may map to Region or solid 2d in autocad. Don't know how it's been mapped.

comment Creating a simulation of our Solar System
you might find this useful. Did you check Solar System Dynamics by Carl D. Murray and Stanley F. Dermott. Mathematica nb, movies and some explanations available.

How about using mesh with subdivision and MaxRecursion > 0 for 3d ones. As mentioned, I thing there are too much points...

comment Efficient circular buffer?
@ Leonid Shifrin OK, thank you. I didn't see any tests with java libs calling from Mathematica. So, I can't say if it's slow or not...

comment Image Processing: Finding Orientation and Position of Symmetry Axes
It can be done either center of gravity(mass) or by the profile of the image projection along the direction of the symmetry axis.

@Jens just corrected the link. Above is the over all process explained as in the paper.

comment Image Processing: Finding Orientation and Position of Symmetry Axes
The code above was just a small bit of the total process. 1. Perform a gradient operation on the image; 2. Obtain the gradient orientation histogram; 3. Search for the convolution peaks of the gradient orientation histogram by using the Fourier transform to obtain the orientations of symmetry axes; 4. Obtain sub-angular positional accuracy by fitting a parabola function, and finding the peak position analytically; 5. Perform symmetry check or evaluation about the obtained symmetry axes; 6. Obtain the position of this symmetry axis by using the center of mass of the object; and draw axes.
