Two object has one intersection - closed line (picture 1).
I wish to make a groove around intersection 3,5mm width and 1 mm deep.
All methods which I practiced from simple shapes (pict 2) to make a groove failed so far.
- two objects from picture 1 has one intersection
- created intersection has 14 intersection to outer shape
- and 7 intersections with plate
That is strange to me…
In order to get one intersection (non-segmented) with theses shapes I moved plate by -0,01mm but it didn’t worked out.
I can make a groove on plate alone by offsetting intersection (now two closed line do I have), create surface between them, extrude it and make a boolean difference with plate.
Point is, I can not later make a boolean union of such plate (with groove) to outer shape.
Please any advices/solutions are welcome - what can be done?
