Hi everyone,
  I am a newbie of LDraw,I have a project now need to import ldd file into 3dsmax,I have already known there is a way to convert it from ldd to leoCAD,and then export 3ds or obj format,what I confusing is how to using missing parts of leoCAD,
below is the file I will export,all units in lego:

Missing units in leoCAD:

I used 1 brick for test,in lego

missing in leoCAD

then ,following the http://www.ldraw.org/cgi-bin/ptscan.cgi?q=4869
I downloaded 4869.dat

parts/4869.dat
Plane Jet Engine Centre


I searched the library path,like below:

 [Image: 5.png]
The 4869.dat has already there

[Image: 8.png]

But why it can not display in leoCAD?Do I missing some steps?Please help,I spent 2 days and did not find a solution,thanks in advance(I also uploaded the ldd and ldr files)

  cannot access private messages
Posted by: Franklin W. Cain - 2018-10-19, 22:33 - Forum: General LDraw.org Discussion - Replies (3)

For some reason, I can not access my Private Messages (PMs). I know I was inactive for quite some time, but I do not recall having my privileges revoked. Is there some glitch preventing me from reading my messages? I ask that one of the admins please look into this, and please let me know what is going on.  

Thanks in advance.

  Ldcad - "buffer exchange" on flexible parts
Posted by: tatubias - 2018-10-17, 23:03 - Forum: LDraw Editors and Viewers - Replies (3)

guys while i was making the building isntruction of a model. and im using a wedo motor. i use the "flexible motor" and make the cable get inserted into the hub.

i was wondering if there is any way to keep the cable unplugged on the building instructions until a specific step. and then plug the cable. its to avoid having the cable hiding some parts of the model.

  Lego models with fusion 360. LDR to fusion360 script
Posted by: stephane ramauge - 2018-10-13, 16:36 - Forum: General LDraw.org Discussion - No Replies

Recently to learn fusion 360, I used lego models to train with this models
Fusion360 is free for learning an can be used during 3 years with only a email address like Maya, 3dsmax,...

My fusion 360 models https://grabcad.com/stephane.ramauge-1

I'm using the tutorials of DK https://grabcad.com/dk/tutorials to build my first parts and models.
DK made lot of pieces in .IPT format (inventor) format. IPT Part numbers follow Bricklink convention.

Maybe someone with python or java skill could make a script to translate .ldr instructions into instructions to build
models using a fusion360 shared library ?

A fusion360 or inventor assembly is series of components with coordinate, rotation, colors like in a LDR models.
A series of script can import nut, screw in .STL format from a online tools dealer for example. 

I think it's possible to parse a .ldr file and translate *.dat from it to .ipt files or fusion360 library component.


With an organized shared library (convention name, scale,...) like ldraw library but for CAD programs (*.IPT files for example) a script could replace the <piece1025.dat> of a ldr file by a <piece1025.ipt>


For example 


Ldr file :
 
colour  x y z a b c d e f g h i piece1025.dat 




Fictive fusion script : 

Insert <piece1025.ipt>

coordinate   x y z

Transform a b c d e f g h I   

 Insert piece9990.ipt

coordinate .......
 

So with the help of a develloper it could be possible in fusion360 to load and  ldr file, translate the instruction for fusion, insert the good piece at the right place and finally construct the model  



Example script for fusion :

It's just an idea  Smile

  Lpub 3d not showing PIL object
Posted by: tatubias - 2018-10-12, 0:23 - Forum: LDraw File Processing and Conversion - Replies (9)

guys im trying to add the wedo 2.0 hub into a model. i have noticed that the object is shown in the building isntruction but its not shown at the PLI. does some one know why? it is due its too big, or it cant find the object in a library?

the object is: 19071c01.dat



0 STEP

1 71 0 0 0 0 -0.005 -1 -0.001 1 -0.005 1 0.001 0 19071c01.dat



i have noticed in some models when objects are not shown in the PLI secction its due the file its not find on the lpub db or something like that as an not valid example it that you may have a file called 3701a.dat and its not shown at the PLI but if you rename it to 3701.dat it appears. i know its not the same object but looks very similar too. and for a building insruction its good enough.

any other object number to replace 19071c01.dat

  LPUB 3d axes length
Posted by: tatubias - 2018-10-10, 21:45 - Forum: LDraw File Processing and Conversion - Replies (4)

Guys when I make the building instructiins I add an axe but it does not shows me the length. I can enable the description to all PLI , but it add to much text to all PLI and I'm only interested in the length of the axe.

I'm using lpub 2.0.2

Is there any work around? Done in lpub3d?


Edit: I'm thinking I can add extra text using the edit menu add text option. This is tedious but it may work. I have not tested yet


Any other ideas, that it does not involve edit the jpg and make a new pdf file?

  Post BrickCon points of discussion
Posted by: Orion Pobursky - 2018-10-08, 16:37 - Forum: Website Suggestions/Requests/Discussion - Replies (7)

During some discussion with various folks at BrickCon, I have a few points I'd like to open up to discussion:

- The main site would do well as a wiki. We have so many drive-by contributors that the wiki concept would work better than the front-end/back-end we have currently. It would also alleviate the admins from much of the theme coding and article maintenance. That said, the contributor agreement would mean no anonymous editing (currently disallowed on the wiki anyway.

- I'd like to bring back the MOTM and SOTM. I think it generated a small amount of traffic to the site. I could even automate it to some degree since LDView is installed on the server.
 and brigl can be use for machines that can handle it.

- The PT needs an overhaul. This was painfully obvious during the server shift last summer.

Thought?

P.S. I have a few more ideas that were brought up but I can't remember them right now.

  LDCad META commands.
Posted by: Orion Pobursky - 2018-10-08, 16:14 - Forum: LDraw Editors and Viewers - Replies (4)

I'd like to make your connection spec official  We can still have the separate connection library and the bar for making it official can be lower and easier to update but I'd really like the connection data to be part of the official library.

I'm also leaning towards making you flexible connection METAs official as well.

I think these 2 areas are the 2 biggest areas where the official library falls down.

Thoughts?

Question META Command for rotating parts for PLI (parts list callouts)
Posted by: Lasse Deleuran - 2018-10-07, 0:04 - Forum: Official File Specifications/Standards - Replies (3)

I have been looking through the various META commands (such as LPub commands for PLI and Callouts) but I have yet to find a META command that informs an instructions renderer of how to properly orient parts for parts lists and BOMs. 

A nice way of orienting parts is to position it with the center at (0,0,0) and placing the camera somewhere along the vector (10, -7, 10). It seems like MLCad does it this way, and I believe this gives a nice view of most parts.

This approach does not work with technic plates (where you can't see the holes), panels with stickers (where the stickers face away from the user), 1x1 bricks with 1 or two studs on sides, and many more, where this normal orientation makes it hard to determine the part.

I have made a crude hack and placed the camera along (10,-15,10) to help out with some of the situations, see this example BOM where 98087 and 47905 can be distinguished (The page currently loads slowly due to lack of optimizations for line type 5 - I am looking into that), but a better approach is needed.

Is there already a commonly used META command for this purpose? I have not been able to find it, but I might have looked the wrong places.

And is there already a library for this kind of positioning of parts? And how does LPub get around this issue. Does it handle this internally?
