Hello,

I've got a question regarding part material take off.

For a correct materieal takeoff I "transfer" the walls to parts and make a material parts takeoff. This give me an more correct result than the normal wall material take off.

Unfortanely i saw there is an error also in this :

If i make a wall with consist out of several layers ( from indoor to outdoor : finish 5, structure, substrate, air and finish 4)

I also make al floor with several layers (from in door to outdoor : finish 4, substrate, structure)

If  i now draw walls and then i make a floor i get the question if the floor needs to cut the walls, so I say yes. Everything seems to be correct in the "original" parts drawing. But if I check the only parts of the walls the structure of the wall ends on finish 4 of the floor , and the finish 4 and substrate don't stop at the wall...

So therefore the material take off is not correct... strange the original state is correct the parts not ?

The only way i can get this correct is to adjust the parts with the handles, but that's alot of work...

Anybody have any idea how to fix this , or have this same problem ?

thx

the question ".....cut the walls..." doesn't mean cut out all layers of the wall.

it just means join the wall with floor.

and when you join walls and floors together, it follows rules that structure cuts substrate&below, substrate cuts thermal/air layer&below, thermal/air layer cuts finish1&below......... all the time.

so you have to consider about this when you make types of walls and floors.
