Blend two parts
I often add part b in the same space as part a.
Parts are from Solidworks.
Say a ribbon and bow, part b, place on an egg, part a. There is quite a bit of overlap of the two parts, in the same space on the player.
PS creates a nozzle path for each part on each layer. So the 'nth' layer of part b is running over the same layer of part a. This leads to big problems.
How can I tell PS to smartly blend the parts to eliminate this.

RE: Blend two parts
Ah - the difference between adding an object and a part. Now I have that solved.
With this new knowledge I have added a 'part' (right click original object). When I go to scale just it, the other part moves up off the plater(as intended, it does not scale). The base of the scaled part remains on the plater. I then have to manually moved the first part down to the plater.
Why would the original part move up?
A bug, or another instance of my not understanding PS?

RE: Blend two parts
Prusa Slicer has a few rules it uses. One of those as you have discovered is the difference between a part and an object. An object can be made up of several parts and in the tree view on the right you will see them listed under the Object so its all nice and logical. Objects and parts obey slightly different rules though.
All Objects MUST have some part of it touching the bed. This is to allow the object to actually be printed. This rule also drives some to rage as they cant understand why they cant position an object above the bed. Parts however can be placed where ever you like as long as some part of the combined Object touches the bed somewhere in the smallest instance. Even if this means that parts of the object aren't printable. Prusa Slicer only goes so far to try and protect users. Basically it tries to make things safer for new users.
With the more recent builds of Prusa Slicer it will also warn you about completely empty layers as this would also technically mean the model wont print. You can get around this by adding very small modifier parts to bridge empty layers, for example if you are stacking a bunch of parts, say covid visors.
Without seeing your actual models or what you are doing re scaling/position then I suspect its the some bit always touching the bed rule thats making it behave unexpectedly.
