did you import?
#import "CC3ParametricMeshNodes.h"
you error gives you unfound instance of method, so you just need to make right import with that method

Question
i am a newbie in cocos3d. I wan to draw a line using cc3linenode.
Here is the code
float arr_location[] = {x,y,z, dx,dy, dz };
CC3LineNode* lineNode = [CC3LineNode nodeWithName: @"Line test"];
[lineNode populateAsLineStripWith: 2
vertices: arr_location
andRetain: YES];
lineNode.color = ccGREEN;
[_lines addObject:lineNode];
[_activeWorld addChild:lineNode];
But when i try this, i get an error like this
Instance method populateAsLineStripWith: vertices: andRetain: is not found(return type defaults to 'id')
