Hello Patricia

Thanks for your reply.

I tried your test and it does work as you state - for a single wall.

However, when you draw a wall box, things get interesting!

The 'front' wall has 'red' on the left and 'green' on the right and operates as you would expect in accordance with the colours of the radio buttons.

If you examine the 'rear' wall, the colours are reversed and the resize works in correspondence with the left or right radio button - not based on the colour of the button.

I guess I could cope with this. BUT, when you work on the sides of the building, then I am completely lost.

Do you get the same result?

I have put together an illustration of the above, but don't know how to attach the file to this message.

Regards

Rob
