Mirroring 42938 - Roland Melkert - 2024-06-07

I've been trying to figure out the LDCad mirror meta parameters needed for "Car Track 16 x  8 x  2 Curve".

Normally you set a rotation point and rotate the part into its own counter part.

But I'm having problems determining that point as the part seems to be slightly off.

I think it should be half x of the highest point at the arc between the 2 red bricks.

But the two red bricks use different x values (non symmetrical?).

It should probably be close to 172 0 0, but this puts it on 320.956369 0 86 instead of 320 0 086

   

Is this part just not suitable for mirroring or I'm a missing something, thoughts?

Found it, it's: 171.38785 0 -0.371868 (couldn't let it rest Angry )

Full meta:

Still seems a weird location to me though.
