Dear Mario,
Danke sehr Benjamin.Gift wrote: ↑Mon Sep 04, 2017 7:46 pm 1. If I replace MultiFuse by Part::Compound, is the fusion issue solved. => Part_compound.png
2. But multi-color-objects falls to anarchy. => Anarchy.png
3. The very next step is to cut all objects with Part:Cut. The cut face will dye another color(selectable). Is this solution ok? => A_lot_of_PartCuts.png, A_lot_of_PartCuts2.png
I need more time…
kind regards Benjamin

* This widget makes an interactively moveable cross-section of the *
* currently visible objects in the currently active document. The *
* cross-sectioning plane is specified by its normal, and the cross- *
* section can be moved along that normal using a slider bar. It can *
* show the cross-section either as an outline or a view of the sliced *
* objects. To run the macro, first download it from this site and *
* install it in your macros directory, then use the menu to call up *
* your list of macros and double-click on this one. It will display *
* a default cross-section and pop up a window to enable you to set *
* the cross-sectioning parameters. Closing the pop-up window will *
* restore the scene to its previous state before the macro was *
* started. *
