Face one build platform + supports?


Hi folks, I might be missing something, but I don’t appear to be able to put an object on the build platform and create supports.

Imagine a wheel and tyre lying on its side, outside edge to the ground, an exaggerated H if you like.

I’d like the feet of the H to be flat on the build platform, then place supports on mini rafts inside the two legs. But as soon as you place any supports the object lifts and you can’t set a zero offset. Also after trying this Preform broke and all supports became unsupported with a gap between the mini rafts and the support trees.

It would be great if this could be added as an option, I can think of many things I’ve printed where this would have been very useful.
