Hello everybody!

I have recently started to use LDCad and LPub3D to create building instructions. I read many tutorials and discussions about both softwares, but I still have some questions.


Substitute parts (LPub3D):

I have tried to use the function "Substitute part" to replace universal joints or motors, as these parts has been modified in my modelization and I have 2 different universal joints in a PLI.. I wanted to change a motor with its cable by a motor without cable for examble. The function seems to be very simple to use, but every time I try, the app crashes. Any ideas?


Group/Remove group (LDCad & LPub3D):

I have read that it's possible to use a function called "Group/Remove group" in MLCad, when you want to use a buffer exchange on more than one step. So it's possible to put a straight flex, and then to replace it by the final oriented flex some steps after. But I didn't found how it's possible to do it with LDCad. So is it really possible?


Step numbers (LPub3D):

In LPub3D, the numbers of the steps are not like in the LEGO manuals, the software counts the steps of the main model independently from the steps of the sub models. But I wonder if you have a tip to change this even if I think it's not possible. ^^


PLI and Step number placement "bug"?

Sometimes it's pretty difficult to place all the elements correctly. I would like to have the step number and the PLI at the top left of the assembly image, with the step number at the left bottom of the PLI. But sometimes there is like a "bug", it's impossible to place all the elements correctly. I have tried different setups, but sometimes, as in the example below, when I want "Step number: Left Bottom of the PLI" it is not placed correctly. How is it possible to fix that?

To have the same positions as in the LEGO manuals, what do I need to place relative to what element, and how?



In the previous page, it worked as I wanted, and I used this:

Hi all, 

Here's my other 42093 C model. Formula Racer with HOG steering and working V8.  Aero components on the forward and rear spoilers can be moved if desired. Instructions can be downloaded here:

As asked for by Orion... here is a quick description of how I generate Architecture name tiles.

- Place in a folder txt2dat.exe tool (I use version 0.2.3)
- place the true type (.ttf) font to use in the same folder (it's simpler than to use the file in Windows font folder). I generally use the ubiquitous Arial font. While the match is not perfect it's OK in most cases.
- Open a command prompt in that folder (there is also a little gui shell, GUItx2d, http://jc-tchang.philohome.com/manuel/tx...tm#guitx2d but for some reason it doesn't work on my machine)
- Key in the command line:

txt2dat -s "Empire State Building" -o empire.dat -l -p 50 -h 80 -c 15 -b 0 Arial.ttf

where
-s "Empire State Building" is the string to generate
-l means don't draw edge lines
-p 50 gives character size. Smaller size may not be detailed enough
-h 80 gives the height of bounding box. Sometimes automatic size result in pattern folding on itself
-c 15 to get white characters
-b 0 on black background
...and the last parameter is the font to use.

Now open the generated file in LDPart editor
- Remove the quads in file (4 sides of the bounding box). The rest of the file should contain only triangles.
- Add the 4162s01 tile 1x8 subpart
- Select text and background and translate by 0.25ldu in y direction (txt2dat creates a sticker so the text is at y=-0.25 ldu, we want it at y=0)
- Scale text appropriately (about 0.27 in x and z directions)
- select background corner vertices (one at a time) and merge them (one at a time) to tile subpart corner vertices (ctrl+e).
- Verify that this operation didn't result in mesh folding on itself (red triangles in BFC mode)
- Save
- Process in datheader to reduce excessive number of digits and to merge triangle to quads.

It looks like there is a problem with LDCad 1.6c when creating flexible parts.
For example, with flexible axles:
When i open the created file with LPub2.3.6 I got an error message that the file 's / faxle1.dat' can not be found.
The file is contained in both the complete.zip and the unpacked files.
If you open the file with LPub 2.3.12, there are no problems.
Flexible axles created with LDCad 1.6b are no problem, neither in 2.3.6 nor in 2.3.12.
Have attached two test files.

Hi all,

Wanted to share one of my MOCs. This one is based off the 42093 set.  I've modeled using stand-in pieces for the 42531 fenders as they weren't in the parts library for stud.io. I used Philo's subfiles from the Parts Tracker to assemble a piece in the Studio PartDesigner, but I'm not sure what the etiquette is for posting MOCs with unofficial parts. If it's alright to do that, I'll rev the file and re-release.

Links to instructions are on this page, which are available in pdf.

Enjoy!

Cheers, Matt

Hi all, 

Found this site while scrounging for part models to do some modeling of my MOCs in Stud.io.  I’m a MAC guy so I suppose I won’t be using LDraw anytime soon, but I’m astounded at the support and community here.  I look forward to working with you all, and thanks for having me.

Cheers,
Matt Walker (aka Cleansupgood)

Hey,

large colour numbers were not compatible with LDPartEditor. It is now corrected.
There is basically no limit anymore (don't try the 32-bit integer maximum ).


As always, you can download LDPE from this page:
http://nilsschmidt1337.github.io/ldparteditor/

Changelog:
(1 bug fix)

With this release the following critical issue is fixed:

1. High colour numbers prevent the colour dialog from showing up.
   

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.
   

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 draw and build a lot of cylindrical structures. The builds turn out good but the drawings are not worth much (IMHO). The cylinders are always made up of two brick segments, a 1x2 brick followed by a 1 round brick, with the second and subsequent rows off set by 1 brick. Pretty standard approach.

I would like to programmatically ( spreadsheet ) develop an LDraw file that has better resolution than I can obtain by tweaking individual bricks in a drawing.

Am studying files that I downloaded of small walls both straight and the same wall curved by a specific number of degrees per segment and am working on how the coordinates are computed. Not as straight forward as I had expected.

I am not a math person so the translation matrices throw me. I was hoping that I could find a way that I could calculate the various values for each row. I was wondering if there was an explanation somewhere of how the translation is done. The actual trig would be wonderful.

One other thing,that I was not able to find, was where do the coordinates refer to. The geometric center of the brick? or someplace else.

It looks like there is no spacing between bricks in the computations. Is that correct?

Any help would be appreciated. If anyone else has tried this please let me know. If this is a Don Quixote situation also let me know.
Thanx,
Ed
