Meanwhile when few of you guys are waiting for RN which is still under closed beta i wrote precious tool (at least for me and few of you) which i was missing for a long time. Framing Helper allows you to overlay the most common composition guidelines over Rhino Viewports and is customizable (guideline fitting, rotation or display color of it).
My bad i didn’t knew it will be stuck at the thing called: Content in validation process - Just got an email. Never added stuff to f4r so as i said i made showoff too early. Sorry, guys. I hope it will be online ASAP.
