Question: Mirror object in LDD via LXFML?

[bratkrk]

Do You have any idea how to change lxflm to make my buliding turn like in mirror?

Hello bratkrk and welcome to Eurobricks. You posted in a very old topic (more then two years old). In these cases, please create a new topic instead (I've done it for you this time).

As for your question - no, at the moment there is as far as I know no tool or code available to mirror an object in LDD. It is a very tricky and difficult task to achieve, furthermore if you start to use more intricate bricks, like those that exist in Left/Right versions or have a centerline that is off center or at 45 degrees.

We need a Lego CAD with mirror building function and support LXF import/export. Not sure SR3D builder or ML CAD have mirror building function or not. But both of them not support LXF import/export.

To render a LDD mirror model:

-Import LDD model to mecabricks.

-Export to blender.

-Use mirror function to instant get a mirror model.(Lego logo on studs become mirror, too)

If that works, we need a Meccabricks > LDD converter.

Good idea to add Meccabricks2LDD export function, but Meccabricks don't have mirror building function. And almost no hope for blender2LDD converter.

To make mirror build a bit faster. We need a tools (maybe to add a function in your LDDmanager). To scan input lxf then replace all parts with L/R version with its opposite one.

Aha, I see now you wrote "export to Blender". Missed that the first time.

Yes, then the mirror is "easy" in that it's the pure geometries being mirrored.

I did look into adding a mirroring function in LDDManager, but gave up after understanding it wouldn't be so easy.

Another sample of pure geometries mirrored. Only the right half (35K pcs) is LDD file imported. The left half is mirror-generated in blender 3D. For huge models it can save hundreds hours of digital building works.
