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
  

Anybody with a suitable code using edge prims for these intersections?

tried several hours couldn't sove it

ldr file I'v upload to google drive  https://drive.google.com/drive/folders/1...sp=sharing

Could somebody help me?

Why is this part 10.2+29.8 in length rather than 10+30? When assembled in an engine, all it does it create a collision:
   

Thanks to all helping me with LDInspector. In the last weeks I wrote a new module to generate instructions from a MPD model. It is far from being complete or feature-rich like LPub3D, but for me it suits better in some situations. The generated file is a LibreOffice Draw (odg) file, so further modification is very easy and only limited by LibreOffice.

You may give it a try if you have Java installed (no need for JavaFX for this module). You only need the jar file and a context definition file LDInspector.ldi - you can use the one created by LDInspector or create one containing one line per LDraw part source like in

• Pro: single-step processor: there are no commands having range limits ("start-end"), the commands only set parameter ("from here on").
  
• Pro: stable behavior even for large projects (tested with >320 pages and >350 steps).
  
• Pro: most options may be changed for each step (for example highlight-color etc.).
  
• Pro: real WYSIWYG for current model step, option to use and/or overwrite LDCad/MLCad ROTSTEP angles.
  
• Pro/Con: not full-featured instruction commands (no arrows, no lines, no number editing), but fully editable in LibreOffice (free placement for all items, changing of all background/frame colors, adding elements like arrows and lines, editable text and numbers).
  
• Pro/Con: focus on steps instead of pages, so (pro) you can later change steps with LDCad without risking already done layouts but (con) you have to re-run the build process to see page layout changes.
  
• Pro/Con: orthogonal projection, no option to have perspective projection.
  
• Pro/Con: completely software rendered, no OpenGL/Vulkan/DirectX acceleration (a bit slow, but no special driver/hardware/library required).
  
• Con: no WYSIWYG-gui for pages.
  

Wow, that's a pretty big bike that LEGO releases here!

Zusammengebaut.com has some nice pictures of the new parts, abd thoese are plenty:

- Two new huge tyres
- New large rim
- Two new shock absorbers
- a new breakdisc
- and finally a new wheel-hub holder

amazing parts...

and of course Sariel's review with even better pictures:

forgot about the windscreen, which is pretty unique

Hi Everyone!

First time posting! Was only lurking until now and once working with stud.io, i realized the complexity of 3D Modeling. 
I have no skills in 3D Modeling at all by myself, but i have enough technical knowledge to realize that the pieces i'm asking for are a living inferno to do!

I'm working on recreating vintage dioramas from the background images on the old LEGO IDEAS books, and after working on castle builds (with instructions downloadable for free on the site https://www.backoftheboxbuilds.com/idea-book-260/) , now I started tackling pirates builds from the same book, but quickly realized that plenty of pieces are missing!

Therefore i'm here to ask if someone could try to tackle the Large Boat Hulls 2559c03 and 2557c03 from vintage pirates sets, as for these pieces, i really cannot find any possible alternatives (like i did for  2552px3)

Hi,

I am trying to use the new BUILD_MOD feature in my instruction, but honestly this feature doesn't seem to be very stable. For example, sometimes, it complains the "BUILD_MOD END" is missing, but apparently, it is there in the source file, as below.

   
   

Is there some best practices that I should follow to make this feature work?

Thanks

Hi, could it be possible to request this part to Stud.io?:
