[LDCad] Problem exporting model to ldd

[Moe]

LDD can be extremly picky at this, but far I know you should be ok when using the default grid or part snapping in LDCad

Did you use a very fine grid while 'eying' it. This shouldn't be necessary as most bricks are aligned to multitudes of 10 (width and dept) and 8 (height). This is also the default grid stepping.

Using a fine grid might have placed things a fraction to far, which LDD won't tolerate.

You could try to select all and while the default grid is active (press 3 while the mouse is in the editing area) use the  placement/snap all to grid option from the right click selection menu.

But many parts might need manual adjusting afterwards.

Yes, I used the normal grid but reduced it to 2’s. And a fine grid for some of those half width bricks. I also zoomed all the way in and checked it fitted properly by rotating the model and checking for any misalignment.
Correction: I used the small grid and further reduced to 2,2,2,5
Edit: I tried the 'Snap all to grid' option and as you said it has moved and rearranged a lot of the bricks.
