unionRoundMask can cause first layer problems #40

Under some circumstances unionRoundMask requires re-flattening of the bottom of the model before slicing.

Consider:

`use <Round-Anything-1.0.4/unionRoundMask.scad> $fn = 36; unionRoundMask( r = 1 , detail = $preview ? 3 : 10 , q= $preview ? 30 : 70, showMask = true ) { cylinder (h=5, r=15);
cylinder (h=10, r=10);

}

translate([40,0,0]) union(){ cylinder (h=5, r=15);
cylinder (h=10, r=10); }`

Examine the bottoms of both objects. Not a big problem, but does require attention if the fillet in near the base of the object.

Hey @RAMilewski,

Screen shots would make this issue a lot clearer.

Do you think this needs to be fixed or just raising it as on FYI?

RAMilewski commented 2 years ago

I think it should at least be documented. It's not really obvious in the slicer so it's easy to wind up with a substandard print until you figure out what's going on. ...but it's not that hard to work around.

..on another topic. unionRoundMask isn't in the set of files you get if you download the PolyRound zip archive.

Yup cool.

And good point I should probably do another release :)
