Incorrect shapes mirroring

[Paul Boyd]

Hi Martin,

Oops - another bug! if you load the attached shapes file, then modify all > mirror all: on X, the two twisted rectangles don't mirror correctly - they just "slide along".

Talking of mirroring shapes, it would be wonderful if it was possible to mirror on the notch, as we can with track templates! For shapes, we can only rotate around the notch.

Right way round:-

Templates and shapes mirrored:-

I like to mirror the track plan and board outlines for planning the wiring. looking at the underside of the board.

Cheers,
Paul

Hi Paul,

Sorry about that. The option to twist a rectangle is a fairly recent function, primarily intended originally for the brick slabs and chair rafts. I've been concentrating too much on the 3D stuff recently and not giving enough thought to the consequences for normal track planning. I will get it fixed, and also an option to mirror shapes on the notch instead of needing a shift afterwards.

Two possible very kludgy work-arounds in the meantime:

1. print on tracing paper and turn it over.

2. export only the shapes to DXF, with X-inversion applied to the export. Re-import the DXF file into the background shapes. It won't be perfect, but it may get you what you want.

Omit all first, and then any colour for the shapes:

Change the X-scaling to -1. Don't forget to change it back afterwards:

Note that rectangles will import as 4 separate lines.

Many thanks for reporting it.

cheers,

Martin.

Thanks Martin,

I realise that this whole mirroring thing is probably not something that's used very much! I'll try your method if I need to print another mirrored copy before the next update.

Cheers,

Hi Paul,

Probably not -- but if it's there it has to work.

Next time:

cheers,

Martin.

Perfect, thank you!
