Split Region
This tool offers a rather easy way to customize print properties of a specific region of a multi-body (or mult-region) part.
Sometimes there is a need to alter physical properties of a section (region) of a part during printing. E.g., changing infill properties, or color.
Using external models as modifiers works, but it creates a disconnected experience because design intent is not captured within the designer. You also end up maintaining an additional model used as modifier separtely. In addition, you have to ensure that model changes according to design changes down the line.
Region modifier tool eliminiates all that by letting you use an entire region as a tool, such that, one of the region (consisting of one ore more shapes) can be designated as a ‘modifier’ region and then using it to cut or split target regions of the part.
