Adding Two Symmetrical Shapes But Extra Nodes Added?


Recommended Posts

I created a curve in Affinity Designer. I copy over, flip the horizontal to create two equal symmetrical shapes. With snapping on I move them so they are flush together, then I add curves again to create a new shape which are these two, identical and symmetrical shapes together. Why then does it add these nodes to the new curve?

Hi Kiarian,

Ideally they should be merged into a single node however the current (boolean operations) code does create additional nodes in a few situations. We are aware of these issues.

There's plans to rewrite/improve this and the expand stroke code in a future version. One thing you may/can try is to add a node to the middle of the vertical line on one (or both) shapes then drag it over the other half of the shape to force an overlap between the two halves, then perform the boolean operation. In some cases it may help to get a clean boolean operation.

Hi MEB,
Thanks for the update. I've noticed I can delete any unnecessary nodes, shift the remaining node to the centre, select node using node tool, then use pen tool, and holding shift to then drag out two equal control handles to make if perfectly symmetrical.
