I created the 8527 - Mindstorms NXT Tribot robot. I used LEGO Digital Designer Whacker robot template and modified it in LEGO Digital Designer and then exported it into an LDraw file. Then I tweaked the LDraw file in LeoCAD and divided the model into submodels and added steps which are the exact same as the official building instructions. I hope this can be added to the official model repository in the future.


Let me know what you think!

I created the 8527 - Mindstorms NXT kit. I created the Tribot with no sensors and is just the three motors and NXT brick template vehicle. I used LEGO Digital Designer Whacker robot template and modified it in LEGO Digital Designer and then exported it into an LDraw file. Then I tweaked the LDraw file in LeoCAD and divided the model into submodels and added steps which are the exact same as the official building instructions.

These files (linked here https://www.ldraw.org/part-updates):
* https://www.ldraw.org/library/updates/complete.zip
* https://www.ldraw.org/library/official/LDConfig.ldr

are being periodically replaced with new versions. This breaks all ports that store cryptographic fingerprints, because they see that these files periodically change and ports fail to build.

For example, the FreeBSD port cad/ldraw would break with every new release of complete.zip and LDConfig.ldr

Could you please add a date of release to these filenames, for example make these URLs look like this:
* https://www.ldraw.org/library/updates/co...201229.zip
* https://www.ldraw.org/library/official/L...201229.ldr


Thank you,

I created the three 8527 - Mindstorms NXT LEGO Digital Designer robots that are from the LEGO Digital Designer software which are Basket Bot, QuickDraw and Whacker. I exported these models from LEGO Digital Designer v2 and tweaked them in LeoCAD by dividing the model into submodels and creating building steps. I made the steps be as close as they can be to the official Mindstorm NXT building instructions by LEGO and with the rest of the attachments I designed the steps to be logically as possible.

In this post I will attach the Basket Bot LDraw file and in post two and three I will attack the QuickDraw and Whacker LDraw files.

I even made PDF building instructions of these three models which were created using LPub3D which I will include in the attached file in the fourth, fifth and sixth post.

This is one of my first LDraw models that I would like to share. I hope this can be added to the official model repository in the future.

Hi Roland

Could you please add keyboard shortcuts for camera rotation to the edit view?

Possibly ALT+Arrow Keys?

Thanks!

I am working on a number of parts from the very early years that are either missing from the library or in need of revision. A number of issues arise about renumbering, part naming, etc., so I've compiled everything here and placed bullets beside those points requiring attention or input.

• I propose the existing 925.dat should be obsoleted and renumbered 925b.dat, and "with 3 internal ribs" should be added to its name.
  
• Many of the existing patterns for 925 would have appeared with 925a, either instead of or along with 925b. Given the difficulty of documenting this with any precision, it is probably not worth the effort.
  

• This matches the numbering of the 2x2 quarter-round bricks 3063a (without) and 3063b (with).
  
• But the names do not match: 716 has "cutouts" whereas 3063 has "stud notches". Should this be fixed?
  

• I did not fix this overlap in 716b.dat, and there are a few other geometry issues besides. A potential project, for anyone seeking one.
  

• Possible "needs work": the raised features on this part should really be outlines rather than solid shapes. Perhaps in a future revision…
  

• The existing u8012 should be renumbered u8012a.dat and "Left" should be added to its name.
  

• 821a.dat: with full tabs
  
• 821b.dat: with partial tabs
  
• The existing 821.dat should be renumbered 821c.dat and "with Studs" should be added to its name.
  

• Should these be new suffixed variants (R and L) of u9187, or given a new base number?
  
• These would be combined with the door into a new shortcut, 822ac02.dat.
  

I have posted a test release for LDView 4.4 Beta 5 to GitHub:

https://github.com/tcobbs/ldview/release...v4.4_Beta5

This release mainly contains bug fixes since Beta 4, along with a few new features. The biggest new feature is the ability to search in the Model Tree Dialog. Also, if edge lines are enabled, the model tree highlight has the edge lines for the highlighted element show through all other geometry in the model, so even a fully hidden element will still be visible.

For this release, the Windows versions are built using new versions of Visual Studio. The 64-bit version is compiled with Visual Studio 2019 (compared to 2015 before), and is no longer compatible with Windows XP. The 32-bit version is compiled with Visual Studio 2017, and should still be compatible with Windows XP.

The ChangeHistory.html file that is included in the release lists all of the changes since LDView 4.3. In the macOS version, ChangeHistory.html is in the dmg. In the Windows version, ChangeHistory.html gets installed to wherever you install LDView (C:\Program Files\LDView by default). I'm actually not sure where it goes in the Linux version. Please see my Alpha 6 announcement for a list of what I feel are the most important changes relative to LDView 4.3.

Please let me know about any problems you find. The preferred way to do that is with LDView's GitHub Issues tracker. However, if you do not want to create a GitHub account so that you can do that, you can reply to this message.

My hope is that this is the last beta release before an official LDView 4.4 release. (I know I said that for the last release, but unfortunately I made too many changes to be comfortable with a final release without one more test release.)

How do you move/drag step picture in LPub3D? I want to center the step picture on the page and it always seems to be more left of center. I tried selecting the picture and dragging it but it will not move when I do this.

A bit of a wierd question, maybe, but what's the fastest ldraw editor? On any platform?

I'm wondering because the project I'm working on right now has a massive ldraw file. 25Mb and well over 100,000 parts. LeoCAD takes almost an hour just to open the file on my MacBook. Even a brand new M1 MacBook takes 3 seconds to redraw it if I change angles.

Would this be much quicker on a PC or in another editor? Would I need to shell out for a chunky graphics card? I have a lot of editing to do so I'm willing to look at any option!

I took a LDraw model I made and broke it up into submodels. Each submodel is not centered when you view the submodel. Is there a way I can move and rotate the submodel but not have the submodel part in the main submodel be moved or rotated? Everythng in the main model is in place and it would be nice if the submodels were centered when viewing the submodels on their own.
