Hi,
Im trying to making a script that places electrical components in our model, based in where the ventilation engineer has placed their components, “a shadow object”. This i have figured out how to do for one object at a time, but i want it to be a bit more dynamic. I have made an Excel schedule where the rows represent a different filter for the linked elements from the vent.model. Here i want the user of the script to have the option to specify the name, type, and parameters of the familys in the vent.model they want to filter by. I also want the option til select what contrition to filter by: N/V=dont filter by this contition E = Equals, C=Contains, BW= Beginswith and EW=Endswith.
Here is the problem i have now. How can I filter the elements by different conditions? I have tried, very poorly, to make a python script that does what i have tried to describe here, but it did not work, i’m no expert in python, but i want to become better at it, so if someone can solve it with python that would teach me a lot but nodes works also.
there are some syntaxe problems in your code, here an example with fixes remember to post your code with the <> tags it will help those who will help you
if metode == "N/V":
resultat = elementer
elif metode == "E":
resultat = elementer == val
elif metode == "C":
resultat = val in elementer
elif metode == "BW":
resultat = elementer.startswith(val)
elif metode == "EW":
resultat = elementer.endswith(val)
else:
resultat = False
if metode == “N/V”:
resultat = elementer
if metode == “E”:
if elementer.equals(val):
resultat = True
else resultat = false
if metode == “C”:
if elementer.contains(val):
resultat = True
else resultat = false
if metode == “BW”:
if elementer.startswith(val):
resultat = True
else resultat = false
if metode == “EW”:
if elementer.endswith(val):
resultat = True
else resultat = false
OUT = resultat>
I tried what you said, but i only got false out of my python node.
@c.poupin the script does not recognize that the list of elements is a list of lists. I have to make the script look in the different sublist for all the elements that match the inputs by the user and return a true or flse value, from there i can filter out the elements with a filter bool mask. kind of like this
import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
def getDataParameter(lstmetode, lstval):
for idx, (metode, val) in enumerate(zip(lstmetode, lstval)):
if metode is not None and val is not None:
return idx, metode, val
lstelementer = IN[0]
lstmetode = IN[1]
lstval = IN[2]
outCheck = []
idx, metode, val = getDataParameter(lstmetode, lstval)
for elementer in lstelementer[idx]:
if metode == "N/V":
resultat = elementer
elif metode == "E":
resultat = elementer == val
elif metode == "C":
resultat = val in elementer
elif metode == "BW":
resultat = elementer.startswith(val)
elif metode == "EW":
resultat = elementer.endswith(val)
else:
resultat = False
outCheck.append(resultat)
OUT = outCheck
Hello @c.poupin
Awesome, thank you, almost there I think that when the metode equals N/V the result should be true, because then the script passes all the elements to the next evaluation. So i see that now the script does not keep the list structure, to the next part, it only evaluate the first sublist. I need it to be adaptive so i can add as many lines in my excel sheet as i want and the script will evaluate all the elements in each sublist by that sublists condition, if that makes sense Here is a picture of how it works now.
I also modified the scrip a little, but i did not get the result i wanted
import sys
import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
def getDataParameter(lstmetode, lstval):
for idx, (metode, val) in enumerate(zip(lstmetode, lstval)):
if metode is not None and val is not None:
return idx, metode, val
lstelementer = IN[0]
lstmetode = IN[1]
lstval = IN[2]
outCheck = []
idx, metode, val = getDataParameter(lstmetode, lstval)
for elementer in lstelementer[idx]:
if metode == "N/V":
resultat = True
elif metode == "E":
resultat = elementer == val
elif metode == "C":
resultat = val in elementer
elif metode == "BW":
resultat = elementer.startswith(val)
elif metode == "EW":
resultat = elementer.endswith(val)
else:
resultat = False
outCheck.append(resultat)
OUT = outCheck
but nodes works also.
