[Can you get rid of masked segments of curves?]

Hi,

This is after the fact of the above conversation. But may help someone else.

I needed to do the same thing. i have all three Affinity Photo/Designer and Publisher programs. However i had been working in Photo at the time while working on my client's logo.

I did the following to subtract curve parts from another curve layer.

* First duplicated my layers just for a backup.

* Created the shapes, then converted to curves to shape into the shaping i needed. In this case it was a rams horn with cut lines into the horn.

* Grouped the curves together for ease of layer organisation.

* Then as mentioned in the help above. I selected the cut lines curves layers of the rams horn. and under Geometry - I merged the Curves.

* Then selected both that merged curve layer and the base horn layer i wished the cut lines to be removed from so they appeared transparent on the horn.

* With both the curve layers selected and the base horn layer below the layer i wished to make transparent. I selected 'Subtract' under the Geometry menu heading. and Done! The layers became transparent and my main rams horn remained a curve and not rasterized.

Hope this makes sense and helps.
