[LDPE] 0.8.50 Beta Released (bugfix / usability)

[Nils Schmidt]

Hey,

this release took a little bit longer than expected, but it includes now 6 bug fixes. And three minor usability enhancements.
Some of the issues were indirectly reported by Gerald and Willy. They provided their log files and I was able to spot some critical entries.
Thank you both!


As always, you can download LDPE from this page:

Changelog:
(3 new features and 6 bug fixes)

With this release you will be able to...

• ...use a button to re-open the 3D view (if no view is shown)
  
• ...see a warning if you try to configure a shortcut key which can't be assigned.
  
• ...start the program with a broken config file (it's not a bug, it's a feature...).
  

The following critical issues were fixed:

1. The program could break if a subfile refered to a non-existent or read-protected nested subfile in very rare cases.
   
2. There was a critical selection problem which occured if you have tried to select a single quad, but you deactivated the selection of quads before (selection filter).
   
3. It was problematic if the program could not read from the official and unoffical LDraw library folder.
   
4. It was impossible to save a file if its directory does not exist anymore.
   
5. There was a breaking bug which could deactivate the duplication check on a single file (did not affect other files).
   
6. Pressing the ESC key reset the (scale) snapping to an unexpected 2.00 value.
   

---

The program was tested intensively with "real world" files.
However, it is still a beta version and something can go wrong in about 140.000 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, this version 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:

• 64-bit Java Runtime Environment (JRE) 1.8
  
• OpenGL 2.1 compatible Graphics Card
  
• Operating System (64-bit): Windows [7 or newer], Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
  
• CPU: Multicore-Processor e.g. Intel Core 2 Duo or AMD Athlon II (>2.0Ghz)
  
• RAM: 4GB
  
• Video-Memory: 1 GB
  
• Free Disk Space: 100 MB
  

Recommended Requirements:

• Operating System (64bit): Windows 7,8,10, Linux [e.g. Ubuntu Linux >=14.4], Mac OS X [>=10.6]
  
• OpenGL 3.3 compatible Graphics Card
  
• CPU: Multicore-Processor with 4 cores (or more)
  
• RAM: >4 GB
  
• Video-Memory: >1 GB
  
• Free Disk Space: 512 MB
  
• For a faster start, LDPartEditor and the LDraw™ library should be installed on an SSD.

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