Perimeter is not correct for my walls

kosta — Thu, 17 Mar 2022 18:50:59 GMT

Hi !

Why perimeter isn't correct ? As far as I know it is just circumference around a wall

1200+1000+2500+2700+200= 7600, but perimeter is 8360 or 8.36 meters in schedule.

What is wrong here ?

@kosta , there are length and area on plan so if you need to extract the two you can show Element Information palette from windows menu and select the wall and you have two buttons in palette one for length and one for area on plan.

For some unknown reason, the perimeter is calculated using the mitre of the walls.

What you are looking for is the width (you already have and the length on inside face and length on outside face.

There are other lengths that may be of use as well.

The problem is the schedule will not add these together for you to get a 'perimeter'.

But the perimeter of a wall is not usually something you would ever need?

You want the lengths of walls or the surface areas.

Hi @Barry Kelly looks like it is calculated that way because it calculates directly as walls are connected under the hood, and accounting mitter or any other connection methods are not correct of course.

"But the perimeter of a wall is not usually something you would ever need?"

Perimeters are handy when you working/scheduling decorative rails so called baseboard or cornice, especially when walls are islands.

If I wanted quantities for rails or cornices, I would model them and get the quantities from those elements, not from the walls.

why would you model something if you just need to depict them in schedule.

No need to create an object, rails are not by pieces but by running meters, you're buying not one two or three pieces but n meters according to perimeter or length.

I would model them so the builder can see where they go.

Plus that gives the most accurate quantities.

Maybe if you have rails on every wall, you don't need to model them, but probably not all walls will have rails.

You would have to be careful to schedule only the walls with rails.

Even then, I would not use perimeter, I would use wall length.

Perimeter as you have discovered will add all ends of the walls, even those that join with other walls.

Of course lengths will not include any ends.

Model the rail and you get exactly what you model, and you can get lengths an not a count of rails,

But what ever works for you is what you should do.
