  Parts Tracker
Posted by: Michael Heidemann - 2012-12-26, 18:36 - Forum: Website Suggestions/Requests/Discussion - Replies (6)

It would be very helpful if the PT reports in any case the occurence of a given filename in the official library such as:

Code:
However, 52031.dat does exist in the Official LDraw Parts library.

Today we get this information only if no entry on the PT matches the search criteria.

I would like to see this information if I enter a number with or without the extension.

Thumbs Up Technic Action Figure Torso with Snowflake Logo and Red Stripes
Posted by: Ignacio Fernandez Galvan - 2012-12-26, 18:24 - Forum: Part Requests - Replies (4)

As seen here: http://www.peeron.com/inv/parts/2698c01px23

The snowflake logo can be found in 4215ap19. I could try to provide a better picture of the torso.

  LSynth result dependent on absolute position
Posted by: Ignacio Fernandez Galvan - 2012-12-26, 15:16 - Forum: All Other Programs. - Replies (2)

Consider this simple file:

Code:
0 SYNTH BEGIN ELECTRIC_CABLE 7
0 SYNTH SHOW
1 1 40 10 0 0 1 0 -1 0 0 0 0 1 LS04.dat
1 1 10 0 0 0 1 0 -1 0 0 0 0 1 LS04.dat
1 1 0 0 0 0 1 0 -1 0 0 0 0 1 LS04.dat
0 SYNTH END

0 SYNTH BEGIN ELECTRIC_CABLE 7
0 SYNTH SHOW
1 1 40 10 500 0 1 0 -1 0 0 0 0 1 LS04.dat
1 1 10 0 500 0 1 0 -1 0 0 0 0 1 LS04.dat
1 1 0 0 500 0 1 0 -1 0 0 0 0 1 LS04.dat
0 SYNTH END

The two portions are exactly the same, the second is just displaced +500z. When processed with LSynth, however, the first portion generates only 24 lines, while the second generates 2911 lines!

I guess this is due to rounding errors and matrix transformations being referred always to (0,0,0), but can it be fixed (other than by splitting the code in two parts)?

  Scrolling within ML CAD parts in Windows 7
Posted by: René Virsik - 2012-12-25, 12:18 - Forum: LDraw Editors and Viewers - Replies (11)

Hello,

at first I wish you all Merry Christmas and many nice CAD models in 2013 ! Wink
I'm new by Windows 7 but not new by ML CAD. Till today I used ML-CAD 3.20 on Windows XP. All worked perfect. Now I installed ML-CAD 3.40 on my new PC with Win7. When I go with mouse on graphic parts list on the left side I can't scroll with mouse scrolling key (on the top od the mouse) down and up between the parts. I can scroll only within the text list above the graphic list. Any idea where's the problem ?
Thanks.

  Nomenclature for tyres
Posted by: Max Martin Richter - 2012-12-24, 14:20 - Forum: Parts Authoring - Replies (6)

Hej,
yesterday, I got a copy of the Power Pull set and just for fun I have looked into our library, if the BIG tyre is available. I found it, but it has an odd name.
I left a comment on the part's page. Steffen BFC'ed the file in the meantime - thanks for that.
Now I was looking for the right name. I checked the wiki and the old Lugnet entries.
And I found out, that our naming system is a bit chaotic (for me). Sometimes it is like the version in our wiki and sometimes it starts with the diameter (like on some Lego tyres). I have checked the rim for the tyre, too. Here it is the same. It doesn't correspond with the wiki.

And another thing: I have no idea, where I should do the measurement at the tyre. At the widest width, at the inside width (because it's a balloon), should I include the bead for the rim in the "percentage" measurement or not and and and.

It would be really great if we could find a way to describe this in a good way.


/Max

  Merry Christmas
Posted by: Max Martin Richter - 2012-12-24, 10:02 - Forum: Off-Topic - Replies (6)

Hej,
I want to wish everybody in the LDraw community a Merry Christmas - especially to the admin, the programmers and the part authors.
I'm not sure where all these persons come from. So I write the main fact in the languages, from which I know, that somebody is participating here.

  • Merry Christmas
  • Joyeux Noël
  • God Jul
  • Vrolijk Kerstfeest
  • Buon Natale
  • Feliz Navidad
  • Fröhliche Weihnachten
and of course the language of the home country of TLG ;-)
  • Glædelig Jul


/Max

  32168 Technic Arm Forked with Flexible Center and Ball Joint
Posted by: Michael Heidemann - 2012-12-23, 17:05 - Forum: Part Requests - Replies (1)

If someone is able to finish my work I am greatly happy. All what I have done so far is packed in this mpd content file.

I look currently through my system for non finished parts. If I find some (like this) I will post it here, so maybe someone else can finish that.

Thumbs Up 4350c01: Electric 4.5V Battery Box 4 x 22 x 2 & 1/3
Posted by: Ignacio Fernandez Galvan - 2012-12-23, 10:09 - Forum: Part Requests - Replies (5)

Anyone willing to model this piece? http://www.peeron.com/inv/parts/4350c01 (and its companion http://www.peeron.com/inv/parts/x472)

I don't have this one, I've only seen it in the instructions for other models, as an extension pack (http://www.peeron.com/inv/sets/8700)

  Acceptable vertex mismatch error
Posted by: Paul Griffin - 2012-12-20, 7:37 - Forum: Parts Authoring - Replies (4)

For parts 2997 and 2998, I have noticed many edges that simply don't match up. In one case, two "identical" vertices overlap by .09 u; in another, there is about a .07 u gap. Without the ability to identify edges, I am unable to smooth normals, and I'm certain I will encounter other side effects.

Should I consider such a mismatch to be /too large/ and request/submit a part update, or should I instead implement some kind of vertex snapping tool? Or should I do both?

It would be useful information if there is some standard on identifying identical vertices, or, at the least, on the minimum acceptable feature size (minimum length of any polygon edge).

  Export of .mpd to single 'stand-alone' .ldr file ?
Posted by: Rob - 2012-12-19, 20:42 - Forum: LDraw Editors and Viewers - Replies (26)

Hi,

Can anyone point me in the direction of an application or utility which will take a multi-part ldraw file (i.e. an .mpd file) and convert it into a single 'standalone' LDR file ?

i.e. something which takes an mpd file and outputs the 'absolute' position and rotation of each part in the model referenced to the origin - not to another part of the model.

Hope that makes sense...

I've had a go writing a conversion myself but got bogged down - has to be recursive I think for multiple 'nested' models.

If no such thing exists could any one give me some tips (not code necessarily) but the method I would need follow to acheive what I'm after ?

Thanks.

Rob @ TCBUK
