Mirror the curvey edges of a rectangle

[tonysussex]

Hello,
In Publisher, I can create a rectangle, convert it to curves, create two or three nodes on, say, the left-hand side of the rectangle and use those nodes to make the rectangle's left-hand edge a little bit curvy (as in the image below). Is there then a way to quickly mirror/copy those curves onto the right-hand side/edge of the rectangle (i.e. so the right and left-hand edges have exactly the same curves)?

Much the easiest way is to duplicate the object, flip either copy horizontally, overlap the two copies and then Boolean ‘Add’ them.

Thank you Alfred.  I'm unclear what "then Boolean ‘Add’ them" means.  I have found that after duplicating and flipping the object as you suggested, selecting both objects/layers and then right-clicking and choosing 'Geometry > Intersect' seems to achieve what I was after.

It is one of the options available from the same Geometry submenu you can see by either doing the right-click or choosing it from the Layer > Geometry submenu. Note that since it is on the Layer > Geometry submenu you can add keyboard shortcuts for any of those boolean options.

'Geometry > Intersect' will discard everything except the overlap region, leaving you with a rectangle. The option you need here is 'Geometry > Add'.

No. Tony was correct to use Geometry>Intersect. Geometry>Add would have created a rectangle.

As so often both Alfred and lepr are correct. It depends on assumptions about details in workflow not explicitly given:

• just duplicate and flip the rectangle -> intersect
• Duplicate, flip and move rect angle to match at the straight vertical edge -> add

There was no need to assume anything. The precise description by Tony was duplicate and flip, followed by Intersect, which indeed gives the required result.

I’m afraid my instructions were imprecise. As has been pointed out, they already overlap once you flip the duplicate. When I said “overlap the two copies” I was assuming that this would involve moving one of them to make the two overlap at the straight edge.

Thanks everyone for your interest and assistance.
