Hi everyone,
I'm new to the forum and made a post regarding this that can be found here, and was suggested by Alfred DeFlaminis from technical support to submit a feature request on this matter.
It would be nice to be able to slice an object in multiple directions at once, according to another object that overlaps with it. Screenshots perhaps would describe it better along with words:
I wanted to model a PCI slot and started by measuring it from a physical motherboard, and once I had all the data I then created a long box at its size (white box in picture). Then I started measuring all the holes, depth and distances and made them out of other boxed-objects. The idea was to insert everything within the base shape to get the big picture of what it might look like when sliced. Once everything was in place I increased the height of all the boxes so they won't swollen within the base shape. All the boxes are for reference purpose to help me align the Slice Plane tool to them to make the cuttings.

I made the first slot transparent so you could see the size and depth of the holes:

The final result is in the screenshot below. To making this I had to slice the base shape with the Slice Plane tool, after aligning the slice plane MANUALLY according to each one of the reference boxes. Then I began extruding the holes down by aligning the action to the bottom of the desired reference hole boxes.

I really hope my explanation makes sense. It would be great if instead of doing all the slicing manually, there would be an option to make one object get sliced according to another object that overlaps with it - as stated, my reference hole boxes.
Thanks!
