Transofm multiple curves at once

[Arturos]

Hello,

I've created an object using multiple curves and added them in one using the Geometry tool. Now, I would like to transform the shape (for example bend it in the middle), what would be the best way to achieve this?

Thanks,

Welcome to the forums @Arturos
If you want the result – after manipulation – to be vectors then you currently (as of 1.8.5) cannot do what you want with the Affinity applications in any way other than manually manipulating each curve.
If you don’t mind the result being a raster then, if you only have access to Designer, you could make your shape into a Textured Image Brush, apply that brush to another curve and then manipulate that curve. (See various forum threads and the Designer Help for Textured Image Brushes and Vector Brushes.)
If you also have access to Photo then you can use various tools – e.g. Mesh Warp, Liquify Persona, etc. – to do what you want.

Note: Other applications are available which can 'bend' vectors; they are well-documented in various other forum threads.
