I' m trying the last few days Revit Architecture to see if it meets the needs of my. The main think i want from a program like Revit is to have material take off. So i spending a lot of hours trying to model the building that i am going to construct. So i have some problems that i can't resolve. First of all columns.I try a lot of things to model columns. First i use architectural columns with walls, and then i put concrete structural columns and join them with the architectural columns and with walls. I seems fine but when i make a material take off the results was not correct. Now i m trying to use structural columns and join them with walls and then place interior a thin wall with finish material. The second problems is beams. Again i use concrete beams and i cant find how to apply finish material. Its not so easy to place and coordinate correct wall for finish material . The last think was slabs. If i apply a finish material bottom of the slab ,and the wall with the same finish material attach to slab, I see in section than the connection is correct. But again in material take off nothing change in the values of finish material before and after the wall attach to it. I use finish material (5) in bottom of the slab and in the wall. Also the concrete beam doesn't join correctly with the slab. The finish material of the slab stays between beam and slab after the join. So with all that i don't have a correct material take off. I m doing something wrong or there is no way to have a correct material take off? Thank you and sorry for my bad English
