  LDCad 1.5 Alpha 1 (win+linux)
Posted by: Roland Melkert - 2015-05-15, 17:44 - Forum: LDraw Editors and Viewers - Replies (131)

With the 1.5 version of LDCad I decided to take another approach then my usual beta versions followed by a 'stable' one.

I wanted to give people the opportunity to play with some of the new features while other are still under construction. Downside of this all is an Alpha version might be less stable then beta ones.

This 1.5 Alpha version houses 2 of the 4 planned major features. Both are pretty much 100% complete but might need some additional fine tuning, so any feedback is appreciated.

The features are:
Window overlay / docking

LDraw source window

Note: To undock a window grab it by some of it's 'dead space', To dock a window hold down the ctrl key at the location you want it to be. Optionally you can also lock the configuration (from the gui menu) to prevent accidental unlocking.

There are also many small features / tweaks, like:
improved scroll bar behavior
Part bin appearance tweaks (allows for a much smaller bin width and horizontal orientation)
And may of the smaller feature requests made in the 1.4b forum thread.

For a full list of all changes read the changeLog.txt file.

You can download the latest Alpha version (from now on) at:

Please let me know your thoughts.

  Request for Mars Mission Alien Parts
Posted by: Tanner S. - 2015-05-14, 1:53 - Forum: Part Requests - No Replies

I did a quick search, and found no other post relating to the request of Mars Mission alien parts.

I am speaking of:
x1765: http://peeron.com/inv/parts/x1765
x1764: http://peeron.com/inv/parts/x1764
62723: http://peeron.com/inv/parts/62723
62724: http://peeron.com/inv/parts/62724

I know they will be very difficult because of a rediculous amount of curved faces and odd shapes, but at least I can say I suggested it.

  Questions about license and conversion of rotation matrix
Posted by: Matthias Deinert - 2015-05-13, 20:47 - Forum: Help - Replies (21)

Hello everyone!

Are you allowed to create a software application that uses the LDR file format (the sets, not the parts) without asking or do I have to register my software somewhere? Because I am working on a game in which you build official and custom sets from the point of view of a minifig and it uses the LDR format to place all the bricks at the right position and players can import their own LDR files as long as they only use the parts that I have modeled for the game (it doesn't use any LDraw parts).

My second question is related to the first as I have a problem with the game. To be more precise, I have trouble converting the LDraw coordinate system to the game engine's system (Unreal Engine 4):
   

In the engine's visual scripting component I hooked up the values like this:
   

On the left you see the index of a line that starts with "1" and all the green 1s in the center column of the image can either be 1 or -1. I would have done it the brute force method and try all combinations but there are 1024 of them which would take too long. Most parts are placed correctly, it's just the angled pieces such as these flowers:
   

They are correctly placed inside the LDR file as well as in my modeling software. If someone with a sharper mind than mine could tell me which values I have to change to convert the axes correctly, I'd be very grateful.

Thank you in advance!

PS: I hope this is the right place for this question.

  Using LPC to make Two Sided Minifig Torso
Posted by: Tanner S. - 2015-05-12, 21:59 - Forum: Parts Author Tools - Replies (12)

Hi all, I'm new to the forum so let me know if I'm putting this in the wrong place.

I am in the process of making designs using LPC (LDraw Pattern Creator) for some models. The specific part I was looking for (the Astro Torso from the Mars Mission theme) is not in the parts library and I have not seen it in the parts tracker, so I decided to make it myself.

I used Inkscape and a few web images to make rough-but-good-enough SVG files for both the front and back, and exported them as a file to use as a background in LPC. What I can't figure out is how to apply the different patterns to the different sides of the torso.

I'm quite a noob at this sort of thing, so any help is much appreciated.

Thumbs Up 20455 - Hemisphere 9 x 4 x 7 (from Jurassic World)
Posted by: Gerald Lasser - 2015-05-08, 20:01 - Forum: Part Requests - Replies (9)

I am working on this part right now:

- Need to check the dimensions again as I think I measured them actually smaller than 9 studs.
- Refine the intersections and edges, as the part is transparent, they need to fit.

   
   

Wanted to have it done in LDPE, however its not starting... (need a reboot)

  [LDPatternCreator] Template Generator for Stickers on Bent Surfaces
Posted by: Gerald Lasser - 2015-05-07, 21:12 - Forum: Parts Author Tools - Replies (1)

As mentioned in the "wrapping" thread, and driven by Philo's step-by-step I made a small XLS generating me the template for Stickers that need to be applied on curved surfaces.

Due to the nature of the spreadsheet, the tool works only if the curve is in one direction only (e.g. Slope Curved 2 x 1, etc.) It could handle more surfaces than the 4 to 5 lines currently in the sheet. I did not tweak it further due to a lack of time and to get the Speed Champions stickers 4 to 5 surfaces are currently sufficient ;-)

Some known problems:
- The ARCCOS produces sometimes an invalid value due to the base value being greater than 1 somewhere far behind the decimal point.
- The generation of the extruded surface with the offset, i.e. Sticker shorter than the surface where it is to be applied is only implemented for 4 surfaces.

Input required:
Quads, only quads right now, and some of the clipping info that will make the sticker fit.

Output:
Two columns for LDPC templates
- one for the cuts that need to be applied (" * " needs to be changed to a Carriage Return)
- second the projection coordinates
For the part:
- the LDRAW code for the sides (Starting point for the first and last points not yet calculated)

What does it do?
- It is calculating the normals for each surface
- Calculates the middle between two normals
- Sets the correct lenght for the normals for the thickness of the sticker
- Generate the list of flat rectangles that later will wrap along the surface
- Generate the projection matrix for LDPC

  MLCad primitive bug?
Posted by: Stephen - 2015-05-07, 12:44 - Forum: LDraw Editors and Viewers - Replies (2)

   

I've just noticed that 6923.dat won't "Zoom To Fit" properly in MLCad 3.4.
Can't say I've ever noticed this problem before on any other part. Maybe I'm not using exotic enough parts Smile

Both "Top" windows above are same size. Both have "Zoom To Fit" run on them.

The difference is on the bottom one I removed these from 6923.dat:

Code:
1 16 -42.313 0 0 -145.703 0 -60.394 0 8 0 80.063 0 -193.154 48\1-8cyli.dat
1 16 42.313 0 0 145.703 0 60.394 0 8 0 -80.063 0 193.154 48\1-8cyli.dat
Is this just an oddity within MLCad about the way this primitive is being used, or is there something wrong with 1-8cyli?
I'm assuming MLCad is possibly calculating the bounding box as though it were 8-8cyli.

I guess all I can really do is hide the part during ongoing construction, or temporarily substitute a dummy part without the 1-8cyli present.

  MLCad ~movedto buggy???
Posted by: Philippe Hurbain - 2015-05-06, 9:29 - Forum: LDraw Editors and Viewers - Replies (25)

I just discovered that MLCad seems to ignore transformation matrix and origin offset when it "upgrades" older version parts!
Attached a sample file and the buggy result I get after "upgrade" and save with MLCad.
Now I am appaled Sad
Did I miss something and is this a known bug?

  [COMPLETED] Part Request: 3070bpXXX (tiles with silver digits)
Posted by: Stephen - 2015-05-04, 10:17 - Forum: Part Requests - Replies (8)

Part request: Tiles with Silver Digits.
3070bpXXX (on BrickLink 060-069, or 060-072)
Tile 1 x 1 with Silver Number 0 Pattern (repeated for 0-9 symbols, and a few more).

I'm requesting these because presently in LDraw there appears to be black tiles with silver letters A-Z, but none with digits 0-9. It's been a major annoyance of mine for some time that we've only got tiles with digits 1-4 (black-on-yellow), so it will be really good to get the newer silver-on-black complete set of digits.

There are also a few other tiles in this sequence, all shown here on BrickLink with yellow backgrounds on the images.
