Simplify3D, connection disapear after slice I have a problem with some models like this (trim_tabs version) : https://www.thingiverse.com/thing:3401852

When I import the model on simplify, the tabs are sticky to the model (see pic3.png) but when I slice it, on the preview, tabs are not sticky to the model (see pic1.png).

I tried to do it on Cura and it works ; tabs stay stiky to the model (see pics2.png).

What's wrong ?
I attach my Simplify and Cura profile to help.

I've tried that item as well.  In fact, other than the heart, I built a remix  which works better but is still difficult to free up after printing.  Those tabs you're concerned about will print better at a very low (thin) layer setting. 

I am pretty sure that the original design is faulty.  All the "leaves" have gears which cause them to rotate when the threaded ring is turned.  But the designer made all leaves identical!  Each one needs its gear's  null-position set differently so that it properly meshes with the thread positions of the outer ring at that leaf's placement.  Some day I may remix to adjust those gear positions....
