I work on this part. It is converted from LDD. I need edges and condlines. In shape from LDD they are not great, and I played around with edger2 tool, but didn't get a great result.

Hi Folks!
Has this part been made?

Hey,

some time ago Philo described a method to convert LDD parts into LDraw parts (http://news.lugnet.com/cad/?n=17697). In the <VertexBuffer> section, Philo referred to, there is next to the <Positions> tag also a <Normals> tag. With these normals there is a calculable way to differ between normal lines (linetype 2) and optional lines (linetype 5).

I wrote a small console application based on .NET 3.5 that can make these calculations. The application is kind of simple and silly; but if you play it right it might help you a lot: you have to add the desired part in the LDD without rotating the view. Than take the 3D screenshot and extract the 3dxml file out of the 3dxml archive. Open the 3dxml file and search for the <VertexBuffer> section. Copy the <Positions> and <Normals> line into a new textfile and save it (e.g. file.txt). Call the new console application with the new file as argument and you will get an LDraw part with lines and optional lines.

Please remember: "Getting the shape is only the tip of the iceberg!". This tool is ment to help part authors to create parts. Please make them LDraw parts first before you add them to the parts tracker.

You can download the tool at http://digital-bricks.de/download/3dxml2dat.zip
The application can be downloaded as it is. I do not take charge for errors or any kind of damage to your system that is caused by this tool.

There are a few options you can play with:

Hi all

Are there any parts that have been created as part of the POV-Ray LGEO library that don't exist as LDraw official/unofficial parts?

I'm interested to know as someone has just released a POV-Ray macro that enables POV-Ray objects to potentially be exported to other 3D file formats - see here for more info:
http://news.povray.org/povray.binaries.i...ay.org%3E/

For more information on the LGEO libray see this link:

Bye for now

Hi-

I'm a die-hard SolidWorks user & wish to import LDraw .dat models into SolidWorks.

I'm having some trouble. Here's what I've tried:

I downloaded LDraw & the entire part library.

I downloaded, purchased, & registered 3DWin from TB Software.

3DWin can convert .dat files to .igs or .stl, both of which can be read by SolidWorks.

When I perform these file conversions, however, the files either won't load into SolidWorks, load but with errors/warnings & come up empty, or import and have just a few curves but no solids and the curves don't even look like the completely correct part.

I know that I'm starting with good .dat files, because MLCad opens up the .dat files just fine.


Does anybody have experience with this conversion? Or, is there already a library of parts models that can be imported into SolidWorks?


Thank you very much,
-Jason


PS--Here's a little more detail on some of the trials & tribulations, if some of you are familiar with the nitty gritty of this process.


1 - STL. After I have created an .STL file with 3DWin & I open the .STL file with SolidWorks, the file opens & is empty--there is no geometry. Tested this with 3001.dat & 3002.dat. When opening an .STL file generated from 1.dat, I get some thin geometry, but no solids, & it's incomplete.

2 - IGS. After I have created an .IGS file with 3DWin & I open the .IGS file with SolidWorks, I get one of the following errors:

a) "This file contains free curves/points which are not desired according to the import options. Do you wish to import them anyway? Yes/No" After I select "Yes", the file opens with a sort of a skeleton of imported curves, but no solid geometry, & the part looks incomplete. (I get these results with file 1.dat).

b) "Unable to read IGS file. File was truncated or contains invalid data. OK". I click "OK" & the box disappears & SolidWorks gives up on opening the file. (I get these results with files 3001.dat & 3002.


During my troubleshooting, I have tried parts 1.dat, 3001.dat, & 3002.dat. All of these open fine in MLCad, so I know that the source .DAT files are OK.

I've been working on some Spyrius sets and was wondering if anybody has or could make the following parts for me:

3626bpx193 Minifig Head with Blue Headband, Red Hair and Eyebrows Pattern
3626bpx252 Minifig Head with Moustache Thin, Stubble and Sideburns Pattern
2446px14 Minifig Accessory Helmet Modern with Silver and Blue Vents Pattern
3039px2 Slope Brick 45 2 x 2 with Horizon Pattern
3039px32 Slope Brick 45 2 x 2 with Yellow Droid Outline on Screen Pattern
4346px15 Container Box 2 x 2 x 2 Door with Slot and Spyrius Pattern

I'd appreciate it.

The LSC has approved an Official Model Respository (OMR) specification.

I have now posted this specification to the LDraw.org Specifications page. I replaced the old OMR guidelines entry in that page. (I created a new document; the old one still exists on the server, but is hopefully not linked to from anywhere.)

I based my formatting for the document on the LDraw 1.0.0 specification. It's possible that I made mistakes in the process of converting the text of the specification posted on this forum into HTML for LDraw.org. Please post in the Parts Authoring and Official File Standards forum if you find any mistakes.

Unificator can be a powerful shape tuning tool...
As you know (or not ), the straight part at the bottom of LDraw slope parts is 4 LDU high, while LDD models this at 5 LDU. Real part are indeed closer to 5 ldu, but reworking all existing LDraw parts would be a nightmare. So, to get consistent parts, LDD or LUT parts must be tweaked.
Here is the method I used for 64225 creation.

• Isolate the lines at y=19, using MLCad and a lot of hiding to access lines (tip: lines are much easier to select if you use a 3 line width in settings > change > rendering). Attached file 64225-isol.dat
  
• Make a subpart of these lines (I tweaked them a bit more to get the proper final shape). File 64225-line2.dat
  
• Include this subpart, move it down one LDU at y=20 ldu. File 64225-subpt.dat
  
• Run Unificator with snap on subfiles, unification distance=3ldu. Automagically you get the result: 64225-subptout.dat

For me the most interesting thing in part patterning. So I am trying a lot there.
I can make pattern in Illustrator and convert it now. Sometimes I even get good results, but there are few problems.
I pattern minifig heads.
1. I use slicerpro for it, but there are few problems.
Head has cylinder half, and few t04o6250.dat in it. But when I attach pattern to it slicerpro deletes some parts of base. Is it possible, not to change base structure? Because it will be difficult, to clean condlines, and restore deleted parts.
2. Patterns to heavy.
Today I tried to pattern this minifig head. But got a lot of problems.
