BrickLink and Digital Design
BrickLink has launched its CAD-like digital building software called Stud.io and it is available for free on both PC and Mac computers.
I saw a Stud.io demo at BrickCon 2016 and although I have never even thought about designing my MOCs using digital design (and never thought I would), I was very impressed with the program. I was also impressed with the developers who were also very willing to listen to the AFOLs in the room in terms of what they wanted to see and how it could be made even better. In addition to various improvements compared to LEGO Digital Designer and LDraw, Stud.io is linked to BrickLink to streamline the parts finding process!
Check out Brothers Brick for a list of key features.
Stud.io is currently available in the Beta test environment. Are you going to check it out?
