So this is likely some noob mistake, some fundamental that I am missing. I can get CallCommand to work great from the console but I can't for the life of me make it work in a script. I'm not sure what I'm doing wrong. The relevant part of the code is towards the bottom. Thanks for your time!

Not a noob mistake at all. It's a tricky one that can happen a lot. Especially in scripts.
Sometimes the object's need to be in the scene(not in memory) and C4D updated before you can go any further.try it this way:
import c4d from c4d import SplineObject from c4d import documents from c4d import BaseTag from c4d import BaseSelect doc = c4d.documents.GetActiveDocument() def add_spline(number_points, spline_length) : '''Returns a linear spline of a specified length that starts at the origin and extends through the y-axis''' segment_length = spline_length / (number_points - 1) spline = c4d.SplineObject(int(number_points), c4d.SPLINETYPE_LINEAR) index = 0 while index <= (int(number_points) - 1) : if index == 0: spline.SetPoint(index, c4d.Vector()) index += 1 else: point_pos = c4d.Vector(0, 0, int((segment_length * index))) spline.SetPoint(index, point_pos) index += 1 return spline def main() : # function creates a linear spline spline = add_spline(10, 500) # create tags constraint_tag = c4d.BaseTag(1018074) # 1018074 //Constraint dynamics_tag = c4d.BaseTag(1018068) # 1018068 //Spline Dynamics # add dynamics tag to spline spline.InsertTag(dynamics_tag) # create null null = c4d.BaseObject(c4d.Onull) # insert null into anchor field for constraint tag constraint_tag[c4d.HAIR_CONSTRAINTS_TAG_ANCHOR_LINK] = null # add constraint tag to spline spline.InsertTag(constraint_tag) # select point 0 on spline (at position 0, 0, 0) all_points = spline.GetPointS() all_points.Select(0) # Add the spline and null to the scene doc.InsertObject(spline) doc.InsertObject(null) # set the spline to be the active object doc.SetActiveObject(spline, 1) # get all tags attached to spline tags = spline.GetTags() #Before we attempt to execute any buttons. Let's first update C4D about all these changes we've made first c4d.DrawViews(c4d.DRAWFLAGS_ONLY_ACTIVE_VIEW|c4d.DRAWFLAGS_NO_THREAD|c4d.DRAWFLAGS_NO_REDUCTION|c4d.DRAWFLAGS_STATICBREAK) #Update cinema 4d # push the button HAIR_CONSTRAINTS_TAG_SET_ANCHOR c4d.CallButton(tags[0], 5000) # 5000 //HAIR_CONSTRAINTS_TAG_SET_ANCHOR c4d.EventAdd() if __name__ == '__main__': main()-ScottA

Beautiful, Scott! Thank you so much. This was definitely one of those sticky problems that's been with me for the last 4 days. Cool technique to learn too. Should come in handy in the future.
