Good tutorial, thanks. One note, you don't have to make a separate field to change the units. You can divide the formula by "1 X" where X is the unit type you are trying to remove. For example, dividing by "1 SF" will remove the square foot value, leaving you with only $, which Revit is fine with. (Area*Cost/1SF)
I was going through this tutorial and I think we should clarify the difference between Cost and Material: Cost. Material: Cost is defined in the Material type (Manage Tab > Materials) and each material within a wall can be given its own cost. Cost is defined in the Family Type properties and essentially gives the entire Wall a price per area. That said, when the Schedule lists all these materials, the Family and Type category will list Basic Wall: Exterior - Brick on Mtl. Stud several times, and if you are using the Cost parameter to calculate the total cost of the wall, you will end up with an enormous pricetag. By adding Material: Name to your schedule you can see that each entry of Basic Wall: Exterior - Brick on Mtl. Stud actually represents a different material within the wall as well as the Default Wall value and so the Cost parameter is using the total cost of the wall for each of these materials, thus pricing your Air layer at the same price as your Brick layer. Meaning, essentially, that if your wall area is 10sf and the Cost is $7/sf, the cost of your wall is now (10sf*$7)*number of materials = (10*7)*6 = $420 per square foot of Basic Wall: Exterior - Brick on Mtl. Stud. So, when you use this scheduling technique, it is a wise idea to add in Material: Name in order to determine which materials are given which costs. When using Material: Cost you either give the Default Wall value a cost ($10/sf) OR you give each material a value that would add up to the $10/sf the whole wall will cost. When using the Cost parameter, the cost of the wall should be divided by the number of materials in the wall so that you aren't multiplying the TOTAL cost of the wall by each material.
A very helpful video, I have a question, is there any way to integrate different Total Cost from each schedule, to a one master or final schedule in order to be like a "total budget"
a blessed day, nice tutorial, but i have question, why if i calculated manually the total cost and the material area it is not the same as the result of calculation of revit?
