I’m pretty excited to show off this new feature as it is something I’ve been wanting to add to Rhino for quite a while.
The Feb 25, 2020 Rhino 7 WIP now includes support for color transparency. So far only layer color can be adjusted (and only on Windows at the moment, sorry Mac people we’re working on it). All objects (surfaces, meshes, SubD, curves, text, points, hatches and text dots) pay attention to this transparency setting attempt to draw with blending.
If you select the layer color in Rhino, you should be presented with a slider on the side that allows you to adjust alpha (I know the slider values are backward… this is very early stuff…). We will be adding support for alpha to individual object properties as well soon.
Vector output for printing, PDF, and SVG pay attention to this transparency as well.
I’m sure we’ll come up with a better sample video, but here’s a quick one I put together to show off this new feature
