set point command

[charper]

I am doing the rubber duck tutorial and do not see the purpose of the set point command. I was able to get all points to transform to the same Z without it. When would you use this command?

SetPt allows you to set the coordinates of one or more control points in X, Y, Z or any combination of the three to a specific keyboard value or a snapped point, either in the world coordinate or local CPlane coordinate systems. Useful for "flattening " things at a specific level, aligning things, creating tangency conditions between curves or surfaces, etc. It is a very useful command.

How did you align the Z coordinates of your points otherwise?

NOte: if you just want to flatten objects onto the current CPlane, the Project to CPlane command is a bit faster. Also, if you select an object (not its control points) then all control points of that object will be transformed. --ch
