This is such an amazing application. Using it makes 3D modelling fun again. Thank you for creating it.
In my opinion, It is still missing some important features. Right now, you can only perform linear and radial repetition on primitive shapes (sphere, cube, cylinder, polygon and prism). You cannot perform it on text shapes, splines or polygon groups.
Also, you can only perform x/y/z axis symmetry on single shapes. You cannot perform it on groups of shapes.
Could you please add the ability to perform linear and radial repetition on text shapes, splines and polygons. Could you please also add the ability to perform x/y/z symmetry to groups of shapes. Adding these features will make modelling all kinds of complex shapes a very easy task.
