Printing outer shell in separate color

[Bli]

I am trying to print the outer shell of a model in a separate color - i.e. the entire model is white, and the outer shell is printed black. In addition to this, I want the black color on the outer shell to be placed only every 20 layers. (I am trying to create a terrain model with visible contour lines).
I thought this would be possible using the "per layer settings", but I can't seem to find any way of switching extruders on the same model.

I posted in the feature requests thread about this - but I'm wondering if anyone has found a solution to this using other methods.

ideaMaker doesn't have an option for define which extruder to print outer shells. Modifier can define which extruder to print which area but you will have to edit it every few layers.

Thanks for the tip, Vicky. I'll try using modifier - and as mentioned - I'm hoping outer shell extruder could be a choice in the per-layer settings in the future.

We will add your request into developing list.

I requested the same feature earlier since I print wood filament items and want to save cost by only printing outer shells with wood and inner with right extruder and more cheaper filament.
With all the features added now with textured infill and shell this is slso a very powerfull setting to have
