Measure distance along curve from starting point to a given point in the curve

[daniel.gutierrez (Daniel)]

Hi,

I have a 3D curve and I need to measure distances from each of the points I have defined (Point On Curve command) so I can shatter the curve and split the curve into elements that I can then import to a structural analysis software. Below is a screenshot of that bit of the script.

Does anyone know a way to do it? Thanks!

Equal Length SubCurves (Irrespective of Curvature)

Your code doesn’t behave the same as mine, regardless of ‘normalize’? It appears that ‘normalize’ is affecting ‘length’ instead of only ‘start’? [subcurve_2020May21a2] I think ‘length’ should not be affected by ‘normalize’: [subcurve_2020May21b] subcurve_2020May21b.gh (11.2 KB) Or: [subcurve_2020May21c] subcurve_2020May21c.gh (12.0 KB)

If the thread title is accurate, maybe you want this?

Where’s your GH file?

[daniel.gutierrez (Daniel)]

Many thanks! It definitely does what I wanted. Just one more thing, what the Relay command doing?

[daniel.gutierrez (Daniel)]

Yeah, that’s what I wanted. Many thanks.

I didn’t want to upload the whole gh file since it contains more things and it could get a bit messy

Relay component explanation

Hey Mitch - they don’t do anything but you can use them to organize your definition. If wires cross components, you can insert a Relay and move that to the top or bottom of that component to deflect the wire. When you have several wires that connect to a component at the beginning of the definition, you can have one wire from that component end in a Relay and branch out further on in the definition.

That’s why the instructions say “minimal versions”: It’s really important to do that.

Apologies, I’m quite new to the forum. I’ll upload minimal versions from now on.

Thanks for the help!
