Extrusion has no attribute 'Vertices'

Hi, i’m a beginner and i am in dire need of help :'(, i
was going to do a radiation simulation, i’ve done it before on rhino 7 and i used the very same grasshopper file on my rhino 8 (but rewrote it so the components are updated), however, on the very last step, it has an error and i can’t seem to figure out why, at first i thought it has something to do with me not installing properly so i redid the installation and…nothing, here i attach a screenshot of the problem, thanks:)

Hello- my guess is the function is looking for a mesh object. If so, he extrusion would need to be converted to a mesh, or have its rendermesh extracted. The MeshBrep component will acceptan extrusion object.

-Pascal

i’ll try that, thank you:)
