In South Africa we have to show plumbing in elevation for council submission purposes. (Not sure if it the same worldwide)
I have used the Show Hidden Lines tool for indicating items behind and below walls, but was pleasantly surprised to see that I could use this tool to indicate plumbing fixtures behind walls.
So just click on the icon, click on the wall, then the plumbing fixture. (This is easily achieved in a wireframe view or by isolating the wall and plumbing fixture categories.)
Change the view to Hidden Lines
This may not be the prescribed way of calculating areas fro a bathroom wall tiling layout for instance, but it has helped me out of a jam once or twice.
So here we go. From your elevation view
Export to a dwg file,
Re-import this into your PLAN VIEW
It should look something like this….
Using your site tools trace a property line around your tiling layout:
This is sometimes confused with creating a new schedule, however the process is just slightly different.
In Settings> Line Patterns
.......and create your new line pattern.
You can add dashes and dots with spaces in between, these are all controlled by a length parameter.
Wouldn't it be nice to add text in there too....
If you are using the generic object styles and you join geometry of a floor slab to a wall, it has a very thin line representing the cut of the slab.
If you go to object style> floor, you will see that you can change the Common Edge Cut, if you change it to about a pen 4, the results are cool.
Remember to save these settings to your template.
