I need your help, the node Curve.parameteratpoint and Curve.ParameterSplit just for single item, when i make data input in array type, the nodes don’t understand, so how i make it work with data input in array type ??

It usually means that you’ll need to use the _List.Map_ node when you get the error _“Warning: One or more…Couldn’t find…arguments of type (\_array,\_array)”_

thanks again to [Vikram Subbaiah](http://dynamobim.com/forums/users/testingwaters/ "View Vikram Subbaiah's profile") , List.Map node is very good when we need to combine 2 array data.
