Hi everyone. I’m trying to add a quantity takeoff criteria for material list to a sample line group. To assign object names to surfaces and corridor shapes I’m planning to use an Excel. What I need to know is how to access the compute materials options. I’ve nodes to create and edit quantity takeoff material criterias but I already have that done manually. I hope you can help me. Thanks.
PD: My plan is to add the quantity takeoff criteria to the sample line group first and the create the sections. If that is not the correct way to do that please correct. I’m not sure if I should create the sections first and then add the criteria. Thanks again.
Hi,
please take a look at this thread, it might help.
This basically does the same as the Compute Materials icon with mapping.
I can understand it but I think that that graph does create a new quantity takeoff criteria, add corridor shapes and then, with the Python script, assign it to a sample line group. Am I right?
I’m going to try it. Thank you so much.
Just one question: do you think there is a way to use an already existing quantity takeoff criteria? Thanks again.
Yeah sorry, I made this back in May and did not use it since so I’m not 100% sure what is happening, but if I’m correct the python scipt does the job (mapping and computing) everything outside is optional. We wanted to skip mapping and creteria creation, for every corridor a unique criteria is created with the coded shapes of the corridor and then that is mapped and computed. But if you already have criterias that part can be skipped. I think the script’s first input is the criteria itself.
So in theory you can use your criteria and selected shapes. But as you can see there is a variable to check if everything is mapped, and if it is false, so not everything is mapped in the criteria I think the CriteriaImport(aka Compute Materials) can’t be done, hence the graph is created this way to avoid this as the criterias are created from the shapes to be mapped.
Sorry to ask. How could I map a criteria that uses surfaces (for cut and fill for example)? I think I would be to add the criteria item but I don’t know how to add the surfaces. Thanks again for your responses.
You can change the MapCorridorShape() Method to MapSurface() using the correct inputs.

But I never used that so I’m not exactly sure how to apply the inputs.
Hi. I’ve using the MapSurface method to map two surfaces for a cut and fill criteria and I get this error.
I think it has something to do with the isMappingCompleted method but the criteria only asks for two surfaces.
Can you guide me in what’s missing? Thanks.
The code in Python is this:

surfacemapping1 = QTOM.MapSurface(nameTN,TNid)
surfacemapping2 = QTOM.MapSurface(nameSUBRAS,SUBRASid)
#TRUE if all surface mapped
completed = QTOM.isMappingCompleted
#add created mapping to sample line group aka compute materials
importcriteriatoslg = QTOMaterialListCollection.ImportCriteria(slgid.MaterialLists,QTOM)
t.Commit()
return completed
# Assign your output to the OUT variable.
OUT = addsurfacetoslg(IN[0],IN[1],IN[2],IN[3],IN[4],IN[5])
First please set the python script node IronPython2 so Dynamo hopefully does not crash and it displays more specific error.
