I often create ‘left’ and ‘right’ sides of things (ie: boxes). Typically, I bring in the dxf and set all the tool paths (holes, part, etc). Then I “tile” the part (to get a second copy beside the first), and follow the “tile” with a “flip V” to invert the new part.
This way I get a left side and a right side…
If I make changes to the tool paths, will the changes be included in the 'tiled/flip V" part?
This would be an easy thing to test on a simple model, but I am leaning towards the tool paths not being updated on both of you are tiling models, not toolpaths. I am not familiar with estlcam, but f360 has a feature in cam that allows you to pattern toolpaths to make repetitive cuts. When the original is modified, all patterned copies get updated.
