LD Pattern Creator Help - Template creation
#1
Hi LD community.

I’m after some help with either understanding the process of importing .dat files into LD Pattern Creator, or creating additional templates.

I’ve used the software for a while now and can create patterns using the supplied templates, but can’t seem to successfully create pieces which are not already supplied. Are there any suggested posts or instructions elsewhere to explain the process of importing existing .dat files from the LDRaw Parts Library and selecting the correct face. For example I can’t successfully find the large face of 1x6x5 panel (59349) to then create my pattern.

Thanks in advance
Adam

Hi Adam,

To generate your own templates, I generally use the following steps:
  • Open the part in LDPE (Part Editor)
  • Select the surface(s) you want to have as a template and save it as a new file, e.g. 59349_pattarea.dat
  • Import the file into 59349_pattarea.dat LDPC (Pattern Creator),
    - observe the correct plane (XY)
    - In the import dialogue, select "Overwrite and Import Projection Data"
  • You could start now, but to use it for later save the Template in LDPC
    - File > Projection Data -> Template
    This wil give it an arbitrary name "New..."
  • Rename the Template in the Editor
    - File > Load Template > Edit/Delete
    - In the Dialogue: Select the last template called "New..." (That should be the one you converted last) and Click "Edit"
    - IF there is pattern-less a sub-file available, you can immediately add it in the export from LDPC, so you can add in the "Additional Lines" area the line "1 16 0 0 0 1 0 0 0 1 0 0 0 1 s/59349s01.dat"
    -> NOTE: the file s/59349s01.dat is not yet existing! I will upload this in a few moments
Now go ahead as usual

EDIT: I can only find on promotional print of this part (59349pb095), is it this one you want to do?

Thanks Gerald,
That's great help, I'm about to spend some time working my way through it.
Any patterns I design are usually custom ones for my own MOC's although I have done a few official ones I could never find like the recent Fergusson Tractor tiles.
I'll keep this thread posted on my success (or failure).
Cheers
Adam

Ha, 2x hours later and I'm still lost trying to actually select the desired face in Part Editor. I hope it's just me, but Part Editor is not user friendly at all.

Gerald,

could you please flesh this out a bit, add some pics and upload it to the wiki?

Thx,

So I managed to create a template (i think).

This is the end result as rendered in Stud.io. 
The design seems to be not the black selected in LDPC and it also seems to show the triangles created in LDPC.
Was i Supposed to offset the pattern at some point to get it to sit on the surface of the brick rather than within the surface?

Could you please add a copy of the code?
It's very hard to see/understand what you want to do from only a rendering.

I'll try.

My rendering is the part that I'm trying to create. The 59349 1x5x6 Panel rotated 270 degrees with the YvesSaintLaurent type across the bottom in black. The part will be a window in trans-clear. The rendering may be a little too small to clearly see that it appears the created YSL type is almost "embedded" behind the surface causing unusual refractions and loss of colour in the text in the render.

This was my process:

1. Using LDPE, open file 59349.dat from the LDraw library.

   

2. Selected the four front face vertices using select>select single vertice +Ctrl.

   

3. Copied and pasted the selected vertices into the new.dat in the text editor section of LDPE.

   

4. Save the new.dat file as 59349_patterndata.dat

5. Open 59349_patterndata.data in LDPE selecting the front face as per instructions above.

   

6. Saved projection data as a template and added the line of code  "1 16 0 0 0 1 0 0 0 1 0 0 0 1 s/59349s01.dat", also copied 59349.dat and pasted, renaming into parts/s/59349s01.dat

7. Created pattern using LDPC and colours 16 and 1 (Black)

   

8. Exported as .dat

Does this adequately explain my process and what I was trying to do?
Thanks in advance.
Adam

Final screenshots and how the pattern appears in Stud.io showing the triangulation patterns.
