Problem creating submodels with Steps using LDCad

[John]

I did notice somehow two lines ended up in front of the first FILE in the after.mpd, I was wondering how that happen.

I think those (blank?) lines are related because they might have corrupted the internal submodel offsets, so the editor starts moving stuff to the wrong place.

I'll try to figure out how those lines are caused (do you know when they first appear?), in the meantime I'm happy there is a simple workaround.

I got it. I had the file opened in LDDesignPad and kept refreshing as I made changes to see what it did.

If I Insert a Step, it adds the 0 STEP line before the 0 FILE line. But if I Append a Step, it adds the 0 STEP line right after the last brick in the current submodel.

So the problem is in the way it is Inserting the 0 STEP line. It should insert it before the first brick in the submodel, but it's inserting in before the submodel file itself. This means when I'm then moving bricks to that step, they are now in a different submodel and under different transforms. Makes total sense.

Hope that helps you squash the bug.

Before Insert of Step:

Code:

0 FILE Red.ldr
0 NAME Red.ldr
0 AUTHOR LEGO Digital Designer 4.3
1 320 0 0 0 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 20 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 40 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 60 1 0 0 0 1 0 0 0 1 3010.dat

After Insert of Step:

Code:

0 STEP
0 FILE Red.ldr
0 NAME Red.ldr
0 AUTHOR LEGO Digital Designer 4.3
1 320 0 0 0 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 20 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 40 1 0 0 0 1 0 0 0 1 3010.dat
1 320 0 0 60 1 0 0 0 1 0 0 0 1 3010.dat
