  LDCad - Information on Grouping
Posted by: Ed Bardet - 2016-03-26, 18:26 - Forum: LDraw Editors and Viewers - Replies (3)

I noticed the section in the user manual for grouping is still pending. Would someone do a brief note as to what the different functions do.
Particularly I'd like to know how to make a group 'permanent'. I selected several elements and grouped them, then selected and copied to another location. After moving I wanted to select the entire copy but, I only get the one element I am closest to. I really need to be able to select and move the entire group. My model has several identical portions and I thought grouping would allow duplication of the group as an entirety.
Thanx,
Ed

  [LDPartEditor] 0.8.8 Beta Released
Posted by: Nils Schmidt - 2016-03-26, 12:16 - Forum: Parts Author Tools - Replies (12)

Yay!

Another day, another release. Curtains up for 0.8.8!

[Image: imgDuke2.png]
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(10 new features and 8 bug fixes)

With this release you will be able to...

  • ...insert a reference line (type 1) with Ctrl+R (Text Editor only)
  • ...enable "Edge Adjacency" in combination with "Select Connected/Touching..." (instead of the default vertex adjacency)
  • ...switch between "solid" edge lines and classic OpenGL lines
  • ...get some usability improvements: When "Insert Objects Behind The Cursor Position" is active,
    a carriage return / linefeed will be inserted (you don't have to hit the Enter button anymore)
  • ...set the pivot point to the manipulator position.
  • ...use a "close" menu item in the context menu of the 3D editor (to close open files in the 3D view).
  • ...use a "close" menu item in the context menu of the file tree (to close open files in the 3D view).
  • ...use the new "two thirds" perspective (similar to the setting in LDView)
  • ...benefit from a better description for the Intersector tool.
  • ...benefit from another line colour during edge/triangle/quad creation

The following critical issues were fixed:
  1. Risk of data loss: A rare deadlock is fixed. It occured during the development of 0.8.8 for the first time.
  2. Select Connected/Touching in combination "with Whole Subfile Selection" did not select the subfile.
  3. Several problems with empty sub-files (like "1-16chrd") are fixed.
  4. Primitve caching issues on Win XP (32 bit) are gone.
  5. The file search for file references/textures did not always use the base path of the current file.
  6. The hide/show state was too volatile.
  7. SymSplitter did not treat the first line of the file.
  8. An uncritical drag&drop type exception is fixed.

The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 100.000 lines of code.

Make sure that you choose the right architecture for your OS and Java Virtual Machine (JVM) (64bit or 32bit).
A short guide how to check if a 64bit JVM is installed on your system is located at the bottom of this message.

  1. Download the zip-Archive
  2. Extract the archive content to the location of your choice
  3. On windows, double-click "run.bat" to start LDPE.
  4. On linux/mac, you have to excecute the shell script "run.sh" to start LDPE.

Please note that this software is in the beta stage. Although, LDPE 0.8.8 was tested, there are already known issues for this release. There is a potential risk of data loss.

You can search for updates if you do the following steps:

  1. On windows, double-click "update.bat" to search for updates.
  2. On linux/mac, you have to excecute the shell script "update.sh".

I listen carefully to your requests and possible complaints. Please leave me a message, with your thoughts and wishes to further improve the software.

LDPE is a 3D CAD application: The overall system requirements are higher. While I recommend to use a powerful 64-bit multicore system, it could be possible, to run LDPE on older machines as well.

System Requirements:

Minimum System Requirements:
  • Java Runtime Environment (JRE) 1.8
  • OpenGL 2.1 compatible Graphics Card
  • Operating System (32/64bit): Windows [XP; Vista; 7 or newer], Mac OS X [>=10.6], Linux [e.g. Ubuntu Linux >=10.4]
  • CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
  • RAM: 4GB
  • Video-Memory: 512 MB
  • Free Disk Space: 100 MB

Recommended Requirements:
  • Operating System (64bit): Windows 7, Mac OS X [>=10.6], Linux [e.g. Ubuntu Linux >=10.4]
  • CPU: Multicore-Processor with 4 cores (or more)
  • RAM: >4 GB
  • Video-Memory: >=1 GB
  • Free Disk Space: 512 MB


--------------------------------------------------------------------------------
How to check your JVM version (32- or 64-bit):
--------------------------------------------------------------------------------

You can try on the command line:

Code:
java -d64 version

If it's not a 64-bit version, you'll get a message that looks like:

Code:
This Java instance does not support a 64-bit JVM. Please install the desired version.

In general, I recommend to install the 64-bit version of the JVM for Java 8.

  Ldraw linux packages
Posted by: Don Heyse - 2016-03-26, 2:23 - Forum: General LDraw.org Discussion - Replies (5)

Does anyone here know anything about this LDraw Linux packages github repository? There's a wrapper script for setting the LDRAWDIR environment variable and I was wondering if it's actually in use, or is it just simply another different solution to the problem of locating the LDraw files on linux.

Thanks,

Don

  LPub3D - POV-Ray rendering not working
Posted by: Jetro de Château - 2016-03-23, 16:19 - Forum: LDraw Editors and Viewers - Replies (2)

I've just installed POV-ray and I'm trying to find out what I can do with it from LPub3D

I have gone to Configuration > Preferences > Rendering, ticked the POV-Ray is installed box and found the path for POV-Ray: (C:\Program Files\POV-Ray\v3.7\bin\pvengine64.exe) and L3P (C:\Program Files (x86)\LDraw\LPub3D\3rdParty\l3p1.4WinB\L3P.EXE).
I have also ticked the LGEO is available box as I installed that too (with the AIOI), but I am confused about what to put in that field. There is no executable, so my best guess is C:\Program Files (x86)\LDraw\LGEO

With this in place I have set Preferred Renderer to POV-Ray and tried to render the first page of a set of instructions I am working on. However, POV-Ray throws error message after error message saying something is wrong. I have tried to figure out how to copy the information in the message pane (POV-Ray itself sends me to the Edit menu, but I can't seem to find what I need there) so I can post it here and ask what I may be doing wrong.

  [LDPartEditor] 0.8.7 Beta Released
Posted by: Nils Schmidt - 2016-03-23, 12:41 - Forum: Parts Author Tools - Replies (27)

Yeah Smile showtime for version 0.8.7!

currently, I am on easter holidays. I have some spare time... and here is the next release! Wink

[Image: imgDuke2.png]
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(6 new features and 8 bug fixes)

With this release you will be able to...

  • ...benefit from a faster program start.
  • ...toggle the visibility of conditional line control points.
  • ...drag&drop files on the 3D editor view.
  • ...drag&drop files on the text editor view.
  • ...use the new "modern" GUI layout on a fresh installation.
  • ...activate anti-aliasing on some linux systems with MESA/Gallium*

The following critical issues were fixed:
  1. Risk of data loss: When you open a file again (which was unsaved in LDPE) the file in the 3D view gets cleared.
  2. "Show selection in text editor" did not work correctly for subfiles, if the text editor was closed before.
  3. "Open Part File" from the 3D editor opens a text editor window, too.
  4. Identical lines are not detected if they have different colours.
  5. CSG does not work with invalid colour numbers.
  6. "Unselect" (Ctrl+Click) does not work for subfiles.
  7. Subfile selection issues with adjacent subfiles.
  8. The coarse/medium/fine grid buttons don't stay pushed.

The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 100.000 lines of code.

  Legal questions
Posted by: Flexon - 2016-03-23, 9:56 - Forum: General LDraw.org Discussion - Replies (1)

How come Lego is okay with programs that so closely depicts their bricks?

Would it be different if the programs which lets you build with Lego cost money?

Has LDraw been in contact with Lego and got their consent to use the design of their bricks?

I am asking because I want to make an app which lets you build with bricks.

  Part snapping plate 1x1 round in LDCad is difficult?
Posted by: Jaco van der Molen - 2016-03-22, 14:43 - Forum: LDraw Editors and Viewers - Replies (5)

Is it me and is this a silly question or does anyone else experience difficulty placing a 1x1 plate round in LDCad with part snapping turned on? Dragging this part from the part bin to the model almost never finds a connection or a strange one for me.

I am having serious trouble placing this part in any model while other (small) parts (like a normal 1x1 plate) work perfectly fine.

Was a little surprised not to find this one, unless it's cunningly hidden under some other part name/number.
