    One Material Takeoff Listing Several Materials

    Here's my dilemma:

    Part 1:
    I need to figure square footage of brick, block, and stone. That's the easy part.
    I also need to figure out quantity of each. The problem is, the factor I need to divide the area by is different for each one. So, how do I create a parameter (or parameters) for each one? I can't just say material: area *5, because that only works for brick, not block or stone. I can't just do 3 parameters, because I'll have wrong values mixed in with correct one. I'll also have different cost for each one, but I think I can just create a few different cost parameters, one for each type of material.

    I know I can do a separate schedule for each, but I'd like to keep it all in one schedule. I know there's a way to do this, I just can't wrap my brain around it.

    Part 2:
    Is there anyway to make a formula for block corners? I was thinking I could take the wall height / 8", then multiply it by the number of corners I have (4 for a rectangular building, for example). Then, subtract that from the total area. But, there isn't a height parameter in the material take offs for walls, just width and length. :crazy:

    Any ideas?

    Ahhh, figured out the first part. Instead of a parameter with a formula that has a manual number, I created another parameter for the factor. Then, the formula is multiplying the two parameters. If that makes sense.

      Geeze, never mind. It's not working. For some stupid reason, the factor parameter I added is screwy.
      I have 4 material types listed (by filters). The factor parameter works for one. When I fill it in for the second material, it also adds it to the fourth. When I change the forth, it changes the first and third. :crazy:

      I added a calculated parameter, changed it to a type parameter, even an instance parameter. I give up. Someone do this for me. :hide:

        Could you post a stripped version of your project? Or, if it's too big, PM me and I'll send you a Dropbox link/
        The first part should work, second part will be tricky.

          Project is done, this is an afterthought after the stone and brick counts were missed by about 30%. It's pretty big. Let me see if I can just get the shell together.

            This is difficult. Basic logic: what height is a wall attached to a sloped roof? What height is a wall with an Edited Profile?
            So no, can't be done with walls.

            There is a workaround though:
            Create a Wall Sweep with an empty profile or with small profile which you then hide in your views by filter. Name it "corner block" or something.
            Apply it vertically to all wall corners.
            Calculate the amount of blocks length/8" in your Wall Sweep schedule

              So you actually have time for afterthoughts???

                its still 6M. What's the limit for rvt files? PM me your email. I'll put it on the Cloud. :thumbsup:

                  Well, when the boss asks if this "new expensive program can figure square footages of materials" I have to say yes. :laugh:

                  Then, I opened my big mouth and said "not only can it do that, it can schedule cost, amount of materials, even how many palettes should arrive on sight". yeah, next time I'll just say yes and that's it. :laugh:

                    You could try using Parts--and Schedule them individually. Just a thought. I know, a certain someone will probably chime in and disagree, but give it a try anyway..
