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

Hi,

Are these useful parts in LDRAW at all?

They have been out for a while now and I wanna use them in LDRAW because they're very useful.

They first appeared in the set 76122 Lego Batcave Clayface Invasion.

I know I can search through the ldraw parts library in different ways or use the parts tracker but the parts are just grouped as one part on sites such as brickset so  it's impossible to know the parts numbers or names.

Regards, Snipe.

If I wanted to export an image and have the export be 1:1 for real life scale at a given dpi is this possible?

I could have sworn this piece was in the official library, but apparently it isn't. Therefore I would like to request the patterned river baseplate for set 6071 - Forestmen's Crossing ( https://www.bricklink.com/v2/catalog/cat...conly%22:0} )

I would do it myself but I just don't have the time at the moment. I suspect it is quite simple and could easily be done from online reference images.

So, I'd like to get a little more comfortable with parts authoring—or more accurately, perhaps, parts editing. I don't see myself soon contributing major new parts to the official library or anything, but I do often find I want to make minor tweaks to existing parts (such as to allow odd connections in Technic assemblies that depend on the physical tolerance of real plastic parts, or to create custom sticker parts, etc.). I think that with the right tools, I wouldn't have much trouble figuring out the process, but it's just a little too abstract to manipulate the raw code of a DAT file without getting visual feedback on what I'm doing. Are there good software programs out there where I could tinker around with the basics?

I should add one major catch—right now, LD Part Editor isn't an option for me. I've encountered a series of technical problems that have so far prevented me from even opening the program, so I have no way to use it. I've reached out for support already, but I realize that this may take some time because LDraw tools are created by volunteers on their free time, so I'm just looking for other options I might use in the meantime. I do also have Studio's Part Designer, but that really doesn't allow you to directly manipulate the various subparts, primitives and so on—unless I'm greatly missing where those capabilities are hidden. I don't think LDCad allows interactive part editing beyond snap info. Should I look into MLCad? Something else? I look forward to everyone's suggestions!
