Default I'm lost

(I'll preface this by saying that I'm new to this--not just AC3D but the whole scene.)

I want to make a cake slice--basically, a quarter of a cylinder, but with rounded edges at the top and bottom of the back surface (hence the need for a sculpty rather than a regular SL shape). I've been at this for hours, and everything I do is just...a disaster.

I've tried subtracting with another shape, and even when it's supposedly lined up along the right vertices, it always manages to remove some random little triangular surface somewhere. I've tried just flat-out deleting surfaces and adding new ones. I've tried...I don't even know anymore.

Probably obviously, the few maps I've exported have been full of black, but I can never really even get the shape right in the first place.

It seems like this should be a simple thing to make, but it's defeating me.

Help, please? Thanks!

I think that generating a quarter of a cylinder the way you want it is way easier than cutting it off something else. Try this:


1 - draw a cross-section of half-a-cake, making sure the "central" vertices are on the Y axis.





2 - rotate it by 90° about the Y axis









In order to make it easier to texturize you may now want to combine all top (and bottom) co-planar surfaces - most applications won't frown at that as long as the resulting surface is convex.

Enjoy your cake :-)
