This is a reorganized and reformatted version of this:

Please read it over and make comments. I'm sure there are errors and clarifications that need to be made before I send it to the LSB for ratification.

Hi,

Today, I'd like to share a project I've been working on for a few years.

It is the idea of being able to describe lego models without the use of physical or digital lego, and in a way that is:

• Very close to English and not too unintuitive
  

• Has fast development time
  

• Is cross platform and highly accessable
  

• Is powerful enough to represent any possible combination of LEGO parts or building techniques
  

• Capable of being translated by a computer into a digital model (though this goal was originally part of a seperate "lego programming language" project)
  

• Flexable parts, hinges, etc are also possible
  

• Still makes the user learn about lego techniques
  

• Can be converted into native LDRAW script
  

Tried to auto-generate a flexible component (a 3-stud length ribbed hose) using LD Design Pad, and got a bad result. 

What did I do wrong?  

Thanks, 
Franklin

Hey,

this release took a little bit longer than expected, but it includes now 6 bug fixes. And three minor usability enhancements.
Some of the issues were indirectly reported by Gerald and Willy. They provided their log files and I was able to spot some critical entries.
Thank you both!


As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(3 new features and 6 bug fixes)

With this release you will be able to...

• ...use a button to re-open the 3D view (if no view is shown)
  
• ...see a warning if you try to configure a shortcut key which can't be assigned.
  
• ...start the program with a broken config file (it's not a bug, it's a feature...).
  

1. The program could break if a subfile refered to a non-existent or read-protected nested subfile in very rare cases.
   
2. There was a critical selection problem which occured if you have tried to select a single quad, but you deactivated the selection of quads before (selection filter).
   
3. It was problematic if the program could not read from the official and unoffical LDraw library folder.
   
4. It was impossible to save a file if its directory does not exist anymore.
   
5. There was a breaking bug which could deactivate the duplication check on a single file (did not affect other files).
   
6. Pressing the ESC key reset the (scale) snapping to an unexpected 2.00 value.
   

1. Download the zip-Archive
   
2. Extract the archive content to the location of your choice
   
3. On windows, double-click "run.bat" to start LDPE.
   
4. On linux/mac, you have to excecute the shell script "run.sh" to start LDPE.
   

1. On windows, double-click "update.bat" to search for updates.
   
2. On linux/mac, you have to excecute the shell script "update.sh".

Sariel has done a nice video of the new Technic Supercar, as a bonus it comes also with a lot of details for the new body parts. Seems Part 18944 is kind of a seed part concerning geometric similarities.

Out of curiosity I have applied the similarities to the triangular panel, I have attached the result, as I want to finish the Minions first.

So feel free to take them further.

at 7:23 the new curved mudguard, also borrowing the curve from 18944.

at 8:41 there is the new 19x3x1 Panel

There is also a quite extensive information on the rims starting at 6:00

An idea for the Parts Request sub-forum:

I think we should indicate completed part requests by assigning a "Post Icon" to the first post, this is then added to the topic view and makes it easier to spot open requests.

I was looking through the available icons, but apart from the "Star" or "Thumbs Up" nothing really fits well, Orion, is it possible to add a tick mark to the selection?

Or add a simple [COMPLETED] to the Thread title?

What do you think?

Hi.

I am flummoxed. I am trying to get LDraw installed & running on a late-2013 Mac using HighSierra 10.13.6.

I have used MLCad on windows for years, but haven't bothered to do a manual LDraw update in a long time.

In reading the "Getting Started:Mac" page, I see that clicking either link in Step 1 takes me to the "Latest Parts" page, which tells me absolutely nothing about using or installing LDraw on a Mac. 

If I were a parent, or an AFOL new to this system, I would leave and never return. I would probably also tell others in my community not to bother with LDraw as it doesn't work.

Even if I could figure out that I needed to download & expand the complete.zip file, doing so leaves me with a bunch of files that I have no idea what to do with. So I am again at a point where I give up and leave.

Can someone expand Step 1 so that there are complete & USEABLE instructions for a Mac installation post-download? Perhaps Allen Smith & Willy Tschager could work on a MacOS AIOI? I would be happy to beta test the instructions or the installer.

I am a longtime member of BayLUG and the Bricks by the Bay convention staff. Most of my MOCs are dioramas (circus, farm/ranch) though I do have some larger buildings.

Thank you in advance for any and all advice. 
Stay home and stay safe. Play Well.

How do you select edges and conds. in LDPE via "Select all" making sure the edges in prims don't get selected ... 'cos "... except Subfile Content" doesn't work. And don't propose to hide the prims prior selection. I'm looking for the easy way.

I checked the rebrickable site, but I don't think this is correct. I hope someone can explain whether this is a mistake or not. It should be the drill piece.

As part of our meeting last year in Billund, we expressed a desired to make the learning curve for authoring parts a little less steep. As part of that, I'm working on clarifying the rules for the Official Library. Recently we've had a discussion about complete assemblies and disallowing sticker shortcuts for stickers applied to single, flat parts. As a result of those discussion, I made a draft revision to the File Format Restrictions for the Official Library. Proposed changes in red:
https://www.ldraw.org/hidden-content/dra...brary.html

I also posted about my concerns about documentation fragmentation. I personally feel that the File Format Restrictions for the Official Library document should one single source for all the rules for parts in the official library. With that reasoning in mind, I think "Official Library Policy On Embedding POV-Ray Code" should be cancelled since those METAs are already disallowed. Also, the "Parts numbering scheme for parts with unknown numbers" and "Official Library Specification for Sticker Parts" should be folded into the main document. There are also some pages on the PT that can be added as well.

Basically, I'm opening the entire "File Format Restrictions for the Official Library" document up for revision. How should this document be laid out? What else should be included? I have the ability to separate sections in to tabs and other formatting tricks. I also think a downloadable PDF for quick, offline reference might be a good idea. Maybe even a Quick Reference One Sheet for commonly used info.

I'd like to have a full and frank discussion about this. Remember, if you have a problem, propose a solution. Also, we're not going to break backwards compatibility. Aside from those 2 rules almost anything goes.
