Extra perimeter for first layer

Hi, I am printing a plane from 3dprints.

 

It is single wall.

the designer states that he uses two perimeters for the first and last layers to enable easier gluing together of the parts.  Too difficult to line up single wall thin prints on the parts.  I can't see anyway to do this.  Anyone have any ideas?

Use either a modifier mesh or height range modifier. Please read the Prusa Slicer Knowledge base if you don’t know what they are.

Thanks, Neophyl ... the modifier works great.  I am able to modify the bottom layers.  Is it possible to use the modifier twice on the one model, so that the top two layers could also have multiple perimeters?

You can define multiple height range modifiers or use multiple normal modifiers.  As many as you can be bothered to create 🙂  Unfortunately theres no easy way I know of to copy/duplicate them.  Well you can copy and paste a modifier mesh but I dont think you can copy height range ones.

Just select rate modifier copy and paste works for me. Make sure the part is selected before pasting. You can even paste to a different part.

I misread neophyl please disregard my previous post. Was thinking of copying modifiers

This is a great feature not available on some other popular slicers.

 

The problem I am having is that it is straight forward modifying the first few layers, but I have trouble modifying, for instance, the top two layers, as I have no idea what the height measurement is without slicing.  How can I ascertain the exact position of the top two layers of perimeters without slicing first?
