In Cura you can move parts below the buildplate on the Z axis and it will cut off whatever is below the buildplate, its really nice for getting rid of faces that are uneven and giving them a nice flat surface to adhere to the buildpalte with
I’m wondering if Preform can do the same? can I select my parts and position them on the z axis? some of the parts features are 0.2mm above the buildplate, if i could move it down just that hair then it would be perfect, but i cannot find a way to do so.
