LDCad 1.6 Alpha 1 (win+linux) |

I decided to share the current 1.6 Alpha version as I'm very keen to get some feedback, especially on the ROTSTEP stuff.
Get it here for windows or Linux
I only compiled the 64 bit Linux version, if someone needs the 32bit one let me know.
As this is a Alpha version it might be very unstable and backwards compatibility with the next alpha or even beta will not be guaranteed. So it is highly recommended to keep them separate from other releases.
This version includes the following major features:
Adjustable hotkey assignments.
Macro scripting.
Many scripting API extensions including many new lua objects.
Full ROTSTEP support.
Many tweaks and some small features, see change log below.
The rotstep rotation can be used while navigating through steps by enabling the new NSR/ASR option in the compass. There is also a new (changeable) shortcut ctrl+b which let you edit the current step's meta.
As a result of the hotkey changes some of the existing hotkeys might act slightly different or might be missing as I haven't had time to double check them all.
Full changelog:
Code: --==1.6 Alpha 1 (30-April-2016)==--
Fixed:
- [GUI] Opening a new window now uses the mouse position correctly for its initial position.
- [GUI] Fixed misc refreshment issues when using a pinned down menu while switching window/views.
- [GUI] Right mouse clicks to open a menu will no longer fail to update active window.
- [Rendering] LDraw TEXMAP parts will no longer render wrong on OpenGL implementations demanding power of two sized textures.
- [Path] Quad validation during loading now uses the same restrains as the generator preventing some generated quads to be deemed 'non flat' during next file load.
- [Springs] Fixed conditional lines between sections.
- [Scripts] Changing the script for a model already associated with one will no longer crash the program.
- [Scripts] Assigning color 16 to a reference will no longer crash/hang the program.
- [Scripts] group:getRef() using an out of range index will no longer crash the program.
- [Scripts] Strings are no longer used as integers when e.g. '1234' is given as a parameter.
- [Scripts] ldc.group() or group:link() will no longer potentially hang / crash the program when used with the recursive option.
- [Scripts] ldc.subfile('someModel.ldr') will no longer result in an unlinked subfile if the 'someModel.ldr' is the editing sessions main model.
- [Scripts] vector:getSignedAngle() no longer returns wrong angles when the supplied vectors are not located on the plane the normal indicates.
- [PartBin] Remove facorite now works as it should.
- [PartBin] matrix:getInvertedPos and matrix:getInvertedOri results are no longer switched.
- [Editing] Inlining multiple items now applies the colors correctly for all items instead of just the first one.
- [Editing] Trackball rotation will no longer make the model disappear in certain situations where the mouse left the program window while rotating.
- [Editing] Double clicking an item in the missing files dialog will no longer crash the program.
- [Editing] The selection is no longer rendered at a wrong/different location in editing views while working with it in the source window.
- [Editing] Canceling a selection cloning action now also correctly update the source window.
- [Editing] Inserting a template will no longer always add it to the last step but to the current one like expected.
- [Editing] Moving a selection to a new submodel will now place the reference to that new model at the same location of the selection start.
- [Animations] Animation playback no longer fails to refresh some of the views while using split editor views.
Improved/Changed:
- [LDraw] You can now use a zip file without 'part' and 'p' folders in it as an unofficial library. It will use the root of the zip as if it where 'parts'.
- [Menus] Moved the editing pin/rectangle status item to the editing settings menu.
- [Menus] Changed the keyboard interaction mode item into radio items so each item can be assigned a hotkey.
- [GUI] As a result of the internal changes made for dynamic hotkeys the menubar will reset to a new default when upgrading to 1.6 the first time on an existing setup.
- [Editing] Removed the edit view interaction after adding content using the source window as it might be very confusing in mo
- [Editing] Copy/paste while using the source window will no longer use the copy paste options. It will work with the clipboard on a one on one basis more closely to a normal text editor.
- [Editing] All STEPPING logics will now see STEP metas as the end indication of a step as the new ROTSTEP support demands this kind of behavior.
- [Editing] Dropping an external file into LDCad while nothing is open yet will now load it immediately.
- [Editing] Moving a selection to a submodel will now offer to create an unofficial part if the selection contains scaled references.
- [SourceWin] Improved the step follow option, it now tries to bring the entire step into view.
- [Scripts] Upgraded to lua 5.3
- [PartBin] Added an optional unofficial part indication to bin cells.
Added:
- [GUI] All hotkeys can now be changed and almost any menu item/general action can be assigned one if needed. Management is done using the new hotkey config dialog.
- [LDraw] Added full support of the ROTSTEP meta as an extension to the plain STEP one.
- [Scripting] Macro scrips can now be used to extend LDCad's functionality dynamically. Management/execution of scripted features are available through the new script menu.
- [Scripting] Added the ldc.macro object for registering macro scripts.
- [Scripting] Added the ldc.dialog object for scripted user interaction.
- [Scripting] Added the ldc.action object for scripted callbacks to any hotkey configurable feature.
- [Scripting] Added the ldc.camera object for view rotation interaction.
- [Scripting] Added the ldc.srcLine object for generic LDraw line interaction.
- [Scripting] Added the ldc.view object for access to an editing window.
- [Scripting] Added the ldc.selection object for access to a current selection.
- [Scripting] Extended the ldc.group, ldc.subfile, ldc.refLine object to work with the new srcLine and selection features.
- [Scripting] Extended the ldc.matrix and ldc.vector object with some lowlevel access functions which make it easier to manipulate e.g. part orientations etc.
- [Scripts] Added a collection of default macro scripts containing a samples and tools script.
- [Animations] Dynamic parts will now be regenerated during playback if needed.
- [Editing] Added a property editor for the step meta (CTRL+B for the current step) which can be used to switch between a normal and ROTSTEP meta or set the rotation angles in a convenient way.
- [Editing] Added an option (hotkey 'B', and also in the compass) to enable the rotation stepping information during building step navigation.
- [Editing] Added an option to the header dialog which controls when and if it is shown for new subfiles.
- [Editing] Added 'all off lib parts', 'all unoff lib parts' and 'all unofficial parts' itmes to the selection menu.
Known issues and limitations:
- [LDraw] Scientific notation (e.g.. 1.323E12) is not supported in LDraw line content.
- [LDraw] LDraw files containing concave quads will render wrong as they are currently processed as if they are twisted.
- [Path] Using circle points at 180 degrees difference to each other might result in a weird rendering after reloading the file using it. The circular points are not designed for this kind of usage, try using bezier points instead.
- [Scripting] File changes to lua files will only be detected for the main script, if the script uses additional modules (include files) a manual reload will be required after changes to them.
- [Editing] During nesting mode some parts will be rendered at the wrong place while moving existing parts around, if those parts live in a sub model that's used more then once in the main model of the session. This is not a big issue because one set of the selection will be at the correct place, and your eye will be on them most of the time.

Translucent Pieces in POV-Ray Discolored |

I feel bad because this is my second "Help" post in the space of one week, but I really want to get this project completed!
I am trying to render a model with several translucent pieces, one being a large Medium-Orange Windscreen. When rendered, this piece and others are terribly discolored, almost to the point where it looks like I didn't even select a color close to the one I intended.
The pieces that are having trouble are:
Windsreen 4 x 7 x 2 Rounded Pionted - Colored Trans Neon Orange
Plate 1 x 1 Round - Colored Trans Neon Orange
Cone 1 x 1 - Colored Trans Light Blue
Dish 3 x 3 Inverted - Colored Trans Light Blue
Plate 1 x 1 Round - Colored Trans Light Blue
Brick 1 x 1 - Colored Trans Medium Blue
The Trans Neon Orange pieces appear bright neon yellow, the Trans Light Blue pieces appear almost colorless, and the Trans Medium Blue appears light blue.
I thought at first it may have been my original color choices, but even after changing to Trans Orange, Trans Medium Blue, and Trans Dark Blue, everything still looks funky.
I found only one article about discoloration in POV-Ray, and it suggested some lines added to the head of the file dealing with gamma adjustments. They didn't seem to help much. I have also tried rendering with a configuration other than the normal light setup, using area lights and jitter, but still no change.
This was with the original colors and light settings:
This was with the switched colors and adjusted light settings:

Hi :)
here is LDPartEditor 0.8.12 with the new PartReview tool.
![[Image: imgDuke2.png]](https://lh3.googleusercontent.com/-fi18ywwsEUo/VOOuvkpsdzI/AAAAAAAAASw/Ax0RRFkleKA/s64-no/imgDuke2.png)
As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/
Changelog:
(9 new features and 4 bug fixes)
With this release you will be able to...
- ...use the new "PartReview" tool. Enter a part name and start a review in no-time!
- ...use the new "Decolour" function to quickly remove all colours from a file.
- ...use the new !LPE CSG_TRANSFORM meta command to transform and clone existing CSG bodies.
- ...use the new !LPE CSG_MESH meta command to convert the following LDraw triangles and quads (type 3 and 4) to a CSG mesh.
- ...use the new !LPE CSG_EXTRUDE meta command to generate a CSG mesh from the following PathTruder input lines (type 2).
- ...adjust the rotation center of the view by double clicking on CSG surfaces.
- ...benefit from better performance of the MeshReducer tool.
- ...benefit from better performance of "Round" (Text Editor only).
- ...benefit from better (but slower) CSG triangulation.
The following critical issues were fixed:
- Mirroring now correctly preserves the surface winding.
- The protractor is now drawn without lighting.
- A selection conflict with protractors and triangles is resolved.
- Issues with "Select All", "Select Same Colour" in combination with CSG are gone.
What will the next release 0.8.13 deliver? An automated way to place rect*.dat primitives, more settings in the options dialog, a cleaner "Add Metadata" GUI layout, ...
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.
- Download the zip-Archive
- Extract the archive content to the location of your choice
- On windows, double-click "run.bat" to start LDPE.
- 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 0.8.12 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:
- On windows, double-click "update.bat" to search for updates.
- 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:
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.

Confusing Installation for Mac OS (Step 1) |

I've searched the Help forum for answers to no avail. There are either old, dead links, or advice written in computer-speak that I don't understand. I have been over the Getting Started page, but when it comes time to download the parts list, they all seem to be Windows files. Step One on the Getting Started page says to follow the instructions carefully, but I can't even find a page that has detailed instructions. Every link that says it's for Mac users -- even tutorials -- takes me to a page that has only links, downloads and tutorials for Windows users. I feel like I'm in a house of mirrors here.
My primary experience is with LDD, and I've never used a CAD-like program. Please talk to me like I'm a dummy. I have friends who use nothing but LDraw, and insist that it's the superior program for serious builders. I keep intending to graduate to it, but I have yet to get very far before giving up. It would help if I could at least get the thing fully installed and running, cuz then my learning curve could begin in earnest. It seems that this software (or at least the set up) is primarily for Windows users, and for people with significant experience in coding and/or IT. Would someone with patience (and a Mac) please walk me through this (possibly "live" via IM)? Thanks!
Bruce
p.s. I'm running OS X El Capitan, if it matters.

I know this request isn't going to be on top of anyone's priority list, but in my quest to complete my set of Technic models I am now down to only a few. 8010 Darth Vader looks pretty bad with his missing parts. - 41671 Bionicle Bohrok Windscreen 4 x 5 x 7 (at least this might be useful to some other people)
- 43363 Technic Darth Vader Helmet (only appears in this set)
- cape (virtually impossible to make)
Anyone up for a challenge?

Hello,
I can not find the LEGO Speed Champions rims and wheels. Are they not there?
I found the part numbers right below and right above but not the actual ones.
I would appreciate it if someone could answer because I made a car that uses them.

Help With Debugging Part |

I'm not sure how long ago it was that I used the LDPattern Creator software to draw out the patterns for the Astro Torso from the Mars Mission theme. I managed to finish it, and somehow attach it to the default torso object. Somehow I got it to open in an .mpd file using Leocad, but now I cannot copy it into the file I need it in. When I try, it appears as the default stud-less rectangular prism. I'd like to be able to copy it into the file at least, and maybe even put it into my parts library, bu I am unskilled at these things.
Is there anyone who would be willing to look at the part to see what might be wrong with it?

PovRay and ldraw frustration |
Posted by: Christian Treczoks - 2016-04-24, 19:14 - Forum: LDraw File Processing and Conversion
- Replies (12)

I don't usually start like this on a forum I'm new to, but the whole stuff is totally frustrating, and I need to vent off some steam. Nonetheless, these are (imho) legal complains about something that should be an out-of-the-box success instead of a chain of failures and frustrations.
I'm really a beginner with all this digital building stuff, but I've learned that ldraw & co can be frustrating to no end.
I started with the all-in-one-installer to create building instructions. I got a lot of help and could get the basics up and running with MLCad (which I had used before to create the models) and LPub3D within a few days. But then it got frustrating. LPub3D produced really, really bad (I'm tempted to say shitty) output. Even when I set the DPI to 600 (and cleared the caches), the PDF was horribly blocky. I finally fixed that by upgrading the provided LPub3D to a more current version. Why does the current all-in-one-installer provide outdated, buggy software?
But even with the updated version, the rendering with LDGLite still just crashes when rendering the model, and I never got the PovRay rendering to work, even after hunting for obscure lg_colors and lg_materials files. The only change I got was that instead of staying open and presenting obscure error messages, it now opens and closes povray without producing anything. It still seems to produce an error of some sorts, but it immediately closes the window, so I cannot tell what the problem is, and the stdout_povray and stderr_povray files are empty.
Hunting for the LGEO library (e.g. to look for updates or to find thoses mysterious lg_colors and lg_materials) files only leads to dead ends - looks like el lutzo closed up shop with his website. Why are those mysterious files (and whatever else may be needed for rendering with PovRay) not part of the all-in-one-installer? I finally found those two files somewhere on sourceforge in another projects archive, but I have absolutely no idea if those are the right ones.
Those rendering problems lead to the idea to use L3P and the L3PAddon to attempt a rendering of the model with PovRay. Sorry, but that was a total failure. The program wants to know the location of some files (which cannot be found within the installation, ldraw files, or program installation directories) and a strange tool (ledit.exe, according to google this is a electric circuit/layout program!?!) that it cannot run at all without.
Maybe this all works for some people who have installed numerous updates over time, have some old files still hanging around from 20 versions ago that some current programs still need, but no installer provides, or have tweaked their system over time to cover some of the problems I found. But it just does not work on a freshly installed system.
Please, take a fresh machine, install the AIOI, and try those things yourself if you don't believe me.
At least, with the updated LPub3D i get a decent PDF with the LDView renderer.
But the program is still buggy on many aspects. E.g. all measurements are in inches, even if the default unit is cm. A A4 page is 29.7 by 21.0 cm, not 11.6929 by 8.2677 (without any unit given, but it looks like inches) in Configuration->Page Setup.
If there is anything I can do to help debugging this whole mess, ask me, and I'll try my best. If a developer needs my mpd files to fix his software, no problem, just ask, and you will be given. But working with a software suite where the left hand does not know what the right hand is doing is utterly frustrating.
Leg bedre,
Christian
