This function is available on the WALL tool and I don't see why it is not included with Beams.<BR /><BR />Before anyone suggest that I use a WALL instead ... I tend to use a beam tool to draw gutters, barges, cornices, skirtings among many other things as they don't tend to clash with the wall reference line as much (yes I realise I can also control the reference line clash with layer priority number). Beams can also slope which is a big bonus.<BR /><BR />One work around I use is to draw the beam &gt; mirror it in plan &gt; ALT+Click to pick up parameters &gt; Start Drawing a mirrored profile - it can be done so why no option?<BR /><BR />Does anyone know of a more practical way to achieve this or know of a good reason why it is not an available function?

You're correct with your comment but only until you mess with the settings a little.<BR /> <BR /> If I observed correctly the instance I mirror the profile in my model and ALT+CLICK it to get it's parameters, the NEW default is now switched and you would have to draw your beams in the opposite direction until you revert it again.<BR /> <BR /> It's like there is a parameter in the background that we can edit using mirror command but it is not available anywhere to toggle in settings.
