> why is it that when you rotate a brick, the x,y,z movement also rotates with it? Hardly to say what exactly you mean without seeing some sreenrecord. I may just guess that you should learn a little about "Relative" and "Absolute" coordinates in LeoCAD (see menu "Edit > Transform", "Transform" buttons on main toolbar and on "Properties" widget).[0] > That makes no sense - surely it's a bug? I'm not sure. UPD: Follow related issue thread[1]; alternatively use rotation arrows[3] for rotate (click on each rotation arrow with mouse and move it) [0] https://i.imgur.com/7sdt8yC.png [1] https://github.com/leozide/leocad/issues/655 [2] https://news.ycombinator.com/item?id=26458863#26464346

If curious, past threads: LeoCAD – A CAD program for creating virtual Lego models - https://news.ycombinator.com/item?id=14801612 - July 2017 (79 comments) LeoCAD software to build Lego models - https://news.ycombinator.com/item?id=9674129 - June 2015 (3 comments) The submitted URL this time was https://github.com/leozide/leocad/releases/tag/v21.03, which is pretty specialized. Since it has been years since the project was discussed, I've changed the URL to its home page.

> I recently got to play with Lego because my daughter, who is five, got interested in it. There are attractive boxes for girls, it's called Lego Friends and the figures are a bit more life like. Nice! ;) If you need user-friendly CAD for creating digital Lego models (for planning builds before build it) try LeoCAD app with LDraw Parts Library.[0,1,2] [0] https://github.com/leozide/leocad/releases/tag/continuous [1] https://www.leocad.org/ [2] https://github.com/symbian9/awesome-ldraw

> Click the image to download the LDraw file of this model. > Model by Koyan Cool! Just test this MPD-model[0] using latest nightly build of LeoCAD[1,2] - structure of submodels not clear, so need redesign this model a bit (will do it later). The Super Car, set 8880, was first released in 1994. Now we need to oil[3] those mechanisms ;-) [0] http://bricksafe.com/files/blakbird/Technicopedia/LDraw/8880...

> Given the limited materials that Lego bricks are made out of, getting sensible default materials and automated lighting would be hella easy. So, don't wast time and give us your pull request! ;-) https://github.com/leozide/leocad/pulls Other option is use Blender with "ImportLDraw" addon for import and render models produced with LeoCAD https://github.com/TobyLobster/ImportLDraw Combination of LeoCAD for modelling & Blender (Cycles Render) for rendering - really COOL thing!
