Custom material parameter in MTO

Hi there,
I'm trying to add a custom material property and I created a shared parameter associated to Materials category.
Now I can see such property from the material browser (lower left icon) and set its value for each material. I did that for a couple materials I need.
I want to have such data accessible in my project so I added a project parameter linked to the shared parameter I created.
Finally I created in my project a MTO schedule for floors (in which the materials I want are used) and inserted such parameter as a new field, but it returns no values.
What am I missing?
Thanks in advance for your help.

What kind of Parameter? Text?

Number, I want to use it as a percentage for calculation.

Huh? Percentage of what? This is a Parameter field added to each Material; no?  Maybe I'm misunderstanding.

You're correct. 

Each material have its own value for this parameter

The value is always 0.xx and expresses the coefficient of additional waste/spare for material calculation.

In the floor MTO I want to retrieve such value to use in in a schedule formula like Material.Area*(1+MaterialWastePercent), returning the overall area including the waste.

Say I have 100sqm floor composed by plastic+ceramic tiles.

In my material property I set 0.05 (5%) waste for plastic and 0.03 (3%) for ceramic tiles.

I expect the formula in MTO read 105sqm for plastic and 103sqm for ceramic tiles.

 

Hope I was clear enough.

Maybe I'm pushing Revit too much?

Thanks for your help.

Okay, so you have assigned a value to each of these Custom Material Parameters, though the Material Browser, and you are saying that you cannot pull this Custom Material Parameter into an MTO -- or are you saying that the Custom Parameter is showing up in the MTO, but not displaying the Values you assigned to it through the Material Browser?

The latter, or so it seems since I managed to add a project parameter that refers to the shared material custom parameter.

Now I'm no more at my pc, tomorrow I will send you a couple screenshot to show what I achieved.

Hi there,

sorry for the late reply.

See link the steps I performed and the results I achieved.

Thanks again for your help.

You missed a step.  Open Material Browser, Select a Material and then click on the "Custom Parameters" button and enter a value for your Shared/Project Parameter.

That's what I think I did in step C.

As you can see from picture C if I reopen the material browser the value for the parameter is there.

What am I missing?

How did you access  the Material?  Go through Floor Edit Assembly.

FWIW: It's anInstance Parameter.

I went through manage>material browser.

Tomorrow I'll try your advice.

Thanks again.

Hi,

I finally managed to get the value in my MTO!

The issue was not *where* I went through to entry the values in the material browser.

I got it to work by looking at the last image you posted and I realized your custom material properties was listed among the available fields, whereas I didn't find them mine... or so it seemed.

On a second deeper sight I did find them and the game was done!

My mistake was creating a NEW parameter in my MTO instead of adding a field from the available ones created before.

 

I took my MTO beyond that at the end and I share with you the final results.

As you can see the fields in light grey are all custom material parameters, while all other ones with bold text are calculated fields.

I then saved it as a view template.

I think this would be very useful for future fast calculations for execution/purchase.

Thanks again for your valuable help for pointing me in the right direction.
