  Static 5 bars linkage angles calculation
Posted by: Philippe Hurbain - 2015-10-24, 8:33 - Forum: General LDraw.org Discussion - Replies (12)

Anyone knows how to calculate the angles of such a 5 bars linkage:
   
Graphically it's relatively simple (intersection of the locus of a 4 bars linkage with the circle of the 5th bar), but analytically it's another story...
The problem surfaced when modeling top support of the boom of 42042 crane B-model that uses this kind of structure

I'll probably use a successive approximation method, but if somone has a better way...

  [LDView] LDView 4.2 Beta 1 for OSX bug report
Posted by: Orion Pobursky - 2015-10-23, 5:21 - Forum: LDraw Editors and Viewers - Replies (2)

Travis,

The export function does not work for LDView 4.2 Beta 1 on OSX. I can pick "Export" from the file menu but the dialog box never appears. This function does work on 4.1. I'm currently running OS X 10.11 El Capitan.

  Where does LGEO live right now
Posted by: Orion Pobursky - 2015-10-23, 5:14 - Forum: Rendering Techniques - Replies (2)

Whist trying to download a fresh copy of the LGEO library, I've found that the link on the LDraw website, http://www.digitalbricks.org/lgeo.html , is broken. Can someone point to me where this library is now?

  Slope Meta Command
Posted by: Orion Pobursky - 2015-10-21, 1:59 - Forum: Official File Specifications/Standards - Replies (21)

I'd like to propose a META for slope texture. Something like:

0 !SLOPE_TEXTURE BEGIN
<faces that have slope texture>
0 !SLOPE TEXTURE END

or if there's only one line:

0 !SLOPE_TEXTURE
<face that has slope texture>

  LDD2LDraw or lxf2ldr
Posted by: Rolf Osterthun - 2015-10-20, 19:18 - Forum: LDraw File Processing and Conversion - Replies (5)

Hey,

the tool for the conversion of LDD files to LDraw files is now available in a new version and ready for testing. It should be able to read .lxf and .lxfml files; both in LXFML version 4 and 5.
Currently it is only possible to generate .ldr files. The documentation and the update of the webpage is pending, I am sorry.

   

You will need a valid ldraw.xml. I hope it works.

Rolf

  Pneumatic valve naming
Posted by: Philippe Hurbain - 2015-10-17, 12:17 - Forum: Parts Authoring - Replies (16)

The 42023 Mercedes Benz Arocs contains a variant of 47223 valve, with modified (stepped) output tubes.
[Image: 4694cc01.jpg]
According to Brickset, this new variant kept the same design number, but 47223a, 47223b and 47223c are used for various positions of switch. How should I name the new variant then?

  LDMiniAssi -new tool-
Posted by: Michael Heidemann - 2015-10-17, 9:20 - Forum: All Other Programs. - Replies (1)

Hi to all

I wrote some time ago an application for Willy to make his life easier in case of updates and maintaining the MLCad.ini.

Now I like to share this also with all other interested users.

You can download from http://ldraw.heidemann.org/index.php?page=ldminiassi

[Image: main.png]

Please use it only with a copy of your real MLCad.ini.

Please note that there is no description how to use. If you are interested and can't find out the way it works, please just ask in reply to this post.

Mike
