I have figured out how to add a COGO POINT at the beginning and end of a polycurve, but I can’t figure out how to place a COGO POINT at the MIDPOINT and RADIUS POINT (center point of curve) ? Any suggestions would be greatly appreciated. Also, I only need these points on curves with a radius greater than 4.5’. Thanks in advance for any help you can throw my way.
Use Curve.PointAtParameter with a parameter of 0.5 to get the midpoint.
If the source of the polycurve is a polyline, then look into using Geometry.Explode to get down to the lines and arcs.
I will give that a try, thanks!
How do I set the parameter value?
Thanks for your time, Happy New Year!
The node should have a “parameter” input that will accept a number (sorry I’m not at my PC right now, not exactly sure what the name of the input port is).
That makes more sense once I see what you did! I didn’t realize I needed to input into the parameter with a Code Block?
I was trying to manually input a value and that’s why it wasn’t working for me!
I am just dipping my toes into the Dynamo world so I have a lot to learn yet. J
Thanks for your help, I really appreciate it!
It doesn’t need to be a code block. It could be a Number or Number Slider node too, for example. I tend to opt for code blocks because I am lazy! You just double-click anywhere to make a code block, so I find that it’s a bit faster.
