mass / density into floor and wall family's

[511970GAGWL]

Hello guys 

i have a question is it possible to add density into wall and floor family's just like beam family's

the reason is because i want to make a schedule where it can calculate the weight of a element. 

 What i did above was added a project parameter. but now i have to do every element on its own

You can add a column that includes the estimated weight of a wall type by your area units, and then another column that multiplies the area times the weight. The weight property is not available in the wall's system family, and it cannot be added to the system family. Only through a schedule, as explained before.

Physical material has density built in. You simply have to add in Autodesk Physical asset and load the setting to your material. There you should define the density of that material.

In schedule, you can use Material: Unit weight and it will add those calculation. If you didn't add the physical asset, it will read as 0.

thank u

It might be too difficult to do it in this way, considering that many walls are made of multiple layers of materials. I think it is better to find the estimated value of 1 square meter (or foot) of each wall type, enter that in a custom parameter in a schedule, and then multiply area by estimated weight per square unit.

This is an example of what a Material Take Off schedule does for just one wall with multiple layers. All these 7 rows refer to one wall:

Duly noted.  Looks like you don't need it anyways. I see that this thread has a solution now. Good for you.  Have a great day.

Keep in mind that not all materials in a wall fill the complete volumes.  For example, steel or wood studs in wall are placed at an interval, so using the material physical properties stretch out of the box for those would give the wrong results.  Instead, you need to create custom physical properties, calculate the weight for different configurations (studs @ 16" o.c. vs 24" o.c., for instance), then assign them to different materials, then assign the different materials to different wall types.

IMHO, using just material take-off schedules to calculates weights of a building will give you very incorrect results,
