non-regular shapes

[Darkvortex87]

I was thinking that perhaps the best shape for an habitat is not supposed to be a circle.
For example in a thorus habitat the G at the bottom of the thorus would be different from the G experienced near the side, due to the difference of radius.
Even a 0.01G difference could provoke weird feelings to the peoples (a 100kg person would "lose" 1kg basically walking a couple hundreds meter) and/or structural problems to large buildings.

It would be cool if we could "draw" the section of an habitat, even just by a drawing in 2d using differently coloured straight lines.
Each colour would represent a different "material" for the wall/floor. for example, brown for soil, grey for steel/structural element, blue for windows.

then the software could check if the drawing is a closed form and create the solid simply by making a 360° turn of the 2d form.
the "G" indicator will need to be only calculated on "soil" level.

You're right about the difference in G level; that applies to all geometries in the game except for Cylinder, which is flat with respect to the G axis (unless you have round endcaps, in which case there's a bit of "hill" at either end).

However, even in a cylinder, you're going to have some G differences from floor to floor of a building. These could be noticeable unless your radius is really huge. For example, if your ground is at r=224 m and spinning at 2 RPM, that's 1.0 G. But the second floor is at .988 G, and the second floor is at 0.975 G (assuming 3-meter floor spacing). There's not much you can do about that.

However, I'm skeptical that this would actually be a problem for anybody. A few percent less weight might put a little spring in your step, but most likely you wouldn't even notice it.

But your drawing-the-profile idea is a fun one... I'll give that some thought. Thanks for the suggestion, and keep 'em coming!
