Copy family instance to follow a curve

Hi

Is there a simple way to place family instances following a curve, where the family orientates to the normal of the curve?

Yes.

Great, any chance you could elaborate?

Hi I’ve uploaded what I’ve done so far.

To elaborate, I’m looking to place family instances at points along a curve aligned to the normal of the curve. The dynamo script attached randomises the families placed and drives the length, but i can’t seem to figure out how to keep them orientated to the curve.

As you can see the result works until the curve slopes up, then the families begin to twist off the curve normal.

Looks good, I can’t really work out the problem from the image you posted. might be worth trying to use “CurveTangentAtParameter”, like this example.
