Official Mindstorms models

Hi there,

as my next contribution I'd like to share several official sets of the Kings Castle 6080 with some extensions: 6022 Horse Cart, 6041 Armor Shop, 6049 Viking Voyager, 6061 Siege Tower, 6067 Guarded Inn, and of course the 6102 Mini Figures Set. I hope the files are all correctly OMRized, thanks again to Philippe and Johann. For simplicity reasons I will upload them in separated posts in this thread.

Any comment or suggestion is highly welcome, best regards
Stefan

I start to wonder about the use cyli/cyls primitives within the arm parts: when they are rendered with primitive substitution, this result in gaps in the arms, very noticeable. Maybe we should inline them...

Yes, I was looking at them yesterday. Don't like them.

And maybe we could also remove that kink inside the elbow? It looks like it has been "forced" to fit the primitives.
I was planing to use your knob in all minifig arm parts. Maybe it is time for a reshape, before we start making patterned arms. Gerald, any opinion?

I must agree with Philo, due to the primitive substitution visible gaps appear when rendering the arms., Inlining some of the prims would for sure benefit the final result

What do you mean with that: that kink inside the elbow

See the kink on left image: http://www.brickshelf.com/gallery/Philo/misc2/3818.png
I'd prefer to see the surfaces spared from the kink into a smoother outer elbow surface

Looking around the forum at other posts and threads discussing improvements to the LDraw file standards etc made me start thinking about individual part behaviours.

Some of these have been discussed and even implemented already but I wonder if they could be grouped and streamlined somehow?

Each part clearly has its "Physical" characteristics. (sorry if i use the incorrect modelling vocabulary)

1. Physical Part - including 
     1a. - Complete Frame
     1b. - Primitives
     1c. - Texture
     1d. - Color
     1e. - Pattern

After hitting some modelling limitations across various platforms, I'm imagining a file standard that could natively describe the various "behaviour" characteristics of each part. Some behaviours are already handled through different methods whilst others seem to be undefined yet.

2. Part Behaviours - including
     2a. - Connectivity (Snapping)
     2b. - Hinge Points (Hinge points, rotation angles, etc)
     2c. - Length (Parts clearly fixed in length, though would allow application to string lengths, pipe lengths, and rubber band type applications. Could this be applied to ideas of elasticity by using open limits for strings etc but defined limits for compression and elasticity?)
     2d. - Flexibility (already being progressively applied to various parts across platforms.)
     2e. - Gravity (to describe how a part behaves with gravity, ie chains and loose string)
     2f. - Elasticity (not sure if this is the best word but the intent to describe a parts ability to stretch (+) or hold tension (-). Intended for use with technic rubber bands etc)
     2g. - Compression (used to  describe the parts ability to compress, imagined for springs in shock absorbers in this instance, could be merged with Elasticity as a negative value.)

Just thoughts.

Hi there,

this is my third OMR-model: 854 Go Kart of 1978.

Known issues:
- The hoses are not symmetrical.
- The steering universal joint does not fit exactly.
- The sticker "9" across multiple bricks is missing.

Thank you Philippe and Johann for the feedback to my other two models - I hope this file is nearly OMR compliant already.

Any feedback is welcome, thank you very much.

Edit: changed wheel color from brick-black to rubber-black as suggested for the 8845 by Philippe.

Regards
Stefan

Hi,
I have tried the tools I use：
stl2dat
LDForge
LDPE/LDPC
txt2dat...etc
These tools are good, but it takes a long time to learn them or use them.
stl2dat needs to make a model that is as accurate as possible to get good parts after conversion.
It is also difficult for LDForge to draw a small part with it.
I want to have a tool like the Cinema 4d. It's easy to draw and easily adjust.
Of course, this is not easy, but I am still looking forward to it coming soon.

I've finished a part and ran it through datheader and everything came back ok. If I understand the naming scheme, this new part would be 3004p0e.dat, correct?

I wasn't able to upload a render of the part, so here's a link. Bricklink part 3004pb009.

I am a Mac user (OSX 10.13.6 High Sierra) and I am going to upgrade to OSX Catalina eventually, but I'm waiting on that.
In the meantime, I am practically certifiable in the latest version of Lego Digital Designer. However, I've never been quite satisfied with its semi-lack of the newest useful bricks (I have no care for the gimmick pieces), as well as old lost-to-time bricks. I have gone on a download bonanza for the past hour and a half since I found out that LDraw is a thing. I also noticed that many of these things cut off at OSX Snow Leopard at the latest, so… yeah. I'm wondering if anybody here knows the MOST UPDATED and LEAST BUGGY software that operates similarly to LDD but through LDraw.
I was relieved to find that there were recent posts on this forum.
Which of these compressed files (on the attached image) are most necessary, and/or which ones would be completely useless to me?

On to the next of the topics I’m uncovering as I delve further into the world of LDraw!

I was building a Technic model and discovered that one of my beams didn’t quite fit onto the pins it’s supposed to—it needed to be “stretched” just a bit (as is common with Technic models with odd angles and connections). I compared my model to another user’s, and I noticed that in his, the beam fit correctly even though all the geometry was the same in both models. I discovered that he had scaled some of the values in the matrix; I copied those values to my beam, and it worked!

So the question simply is, when this situation arises, how do I determine which values to scale in the matrix? Typically I’ll just need to make a part longer or shorter or taller by a small fraction. Can I do this interactively in LDCad, or do I just calculate scale factors based on the distance I need (and how do I know which boxes are the correct ones to change)?

Hi there,

being fascinated by the LDraw community and LDCad of Roland Melkert, I want to give back something.  

This is my first attempt to build an OMR and therefore looked at the spec. Unfortunately, I didn't get MPDCenter running on my XUbuntu machine, so instead of "posting an OMR file" I rather like to ask: what do I have to do with the attached file before posting it as an OMR-proposal for the "603 Sidecar" set of 1978?  

I'm doubtful particularly in file naming and part choosing. I'd like to contribute more (like 10218 pet shop which is uploaded to "Modular Buildings"), but want to start with manageable sets.

Thank you so much, best regards
Stefan
