| James Jessiman Memorial Award for 2021 awarded to Leonardo Zide |

The LDraw.org Steering Committee is pleased to announce that the 2021 James Jessiman Memorial Award (JJMA) recipient is Leonardo Zide.
Leonardo got involved with digital LEGO in the 90s, when he started developing LeoCAD. Later he heard about the L-CAD mailing list in rec.toys.lego and met the early members of the LDraw community there.
LeoCAD was created initially as a standalone application, with its own parts library and file format, but soon it was updated to adopt the LDraw library and file format. It gets regular updates and is part of the LDraw All-In-One-Installer.
Leonardo authored a few parts and contributed fixes to existing parts early on but isn't involved with parts creation anymore. He's a programmer and works with people in the community to develop ideas for the library and file format.
More information on the JJMA can be found at: https://www.ldraw.org/article/222.html
On behalf of the LDraw Steering Committee, we thank Leonardo for his contributions and look forward to working with him in the future.

| Aligning parts using rotation scripts |

1. Background
A few months ago, I wrote a Lua script for LDCad to animate the rotation of a 4 (or 3) bar linkage, posting the script to the LDraw forum. Writing that script got me thinking about writing a script which would determine the joining point for two parts, each being rotated about their own designated rotation point.
I’ve now written a version of the script. This post describes how to use the script and provides details about downloading and installing the script.
2. Expectations
The aim of the script is to provide a point-and-click mechanism to rotate parts within LDCad. Conceptually, the parts serve different purposes; some are identified as a rotation origin, some are identified as being aligned to another part and some parts are those which are being rotated. Although this post tends to use the term part, the script can also be used with sub-files.
The script provides solutions for two different scenarios - rotating a single part to a designated alignment point
- rotating two parts to a join point common to both parts
Images from an incomplete model of set 9748-1 (a current work-in-progress) illustrate the script's capabilities.
