Removing a thin line across e.g. brickwork or roof tiles how ?

You’re not missing a secret setting — Photoshop doesn’t currently have a “one-click pattern-aware paint” tool that will auto-extend things like brick or roof tiles perfectly.

A couple of workarounds that get you closer:

• Clone Stamp with Pattern Preview – Instead of the Healing Brush, set Clone Stamp to “Aligned” and lower the hardness/opacity. You can sample along a straight edge and paint across, which helps with repeating structures like brickwork.

• Content-Aware Fill (Edit > Content-Aware Fill) – This can work better than Healing for larger areas. You can define the sampling area manually so Photoshop looks at just the right side of the image to patch from.

• Pattern Preview / Define Pattern – If it’s a repeating texture, define a small clean area as a pattern and then fill/paint with that. Works best on uniform brick or tile areas.

• Plugins / 3rd Party Tools – A few tools (like AKVIS Retoucher or specialized texture synthesis plugins) are designed for this, and sometimes outperform native PS tools for heavy repetition tasks.

It’s true, a fully AI-driven “smart tile matcher” would be a game changer for these kinds of edits — you’re not the only one wishing for it! Right now, it’s mostly about mixing Clone + Content-Aware Fill and being strategic with selections.

I would expect some of those tools, at least, to handle something like a cable crossing brickwork.  Can you show us the original image BEFORE you tried to edit it?  Make it full res, or at least big enough to be meaningful.

Describe your workflow.  i.e. what was your brush size when using the Remove Tool reslative to the cable/artefact?

You mention moving from CS6 to the current version, so I am wondering if you have not yet got the hang of some of the new tools?  

The  "get it one" is suppossed to be "get it over", use the tool, then confirm with the check mark, in the image below it's right near the middle of the top window.
