Is there a way to simplify a polyline faster than using simplify curve? I have large amounts of polylines with straight segments made up of multiple segments. I’m looking for the fastest way to simplify straight sections into a single segment. Is there a way to take advantage of the input curve being a polyline (rather than a curve) ?

Have you tried with [Discontinuity] ?

If your problem is about the speed of the solution, using discontinuity instead of simplify should give you some valuable “speed-up”…

Awesome, measuring now…

50% performance improvement!

The L (Level) setting is important:

L=1 is a bit slower

L=2 is 50% faster

L=3 is about 40% faster

**BEWARE!** I never paid attention to the ‘L’ input of `Discontinuity` but just discovered something that is **not good** about using ‘L=2’ *(curvature)*.

A standard trick to get the center of a rectangle is to take the `Average` of its discontinuity points. This is much faster than `Area` ‘C’ *(Centroid)* and can make a huge difference when dealing with hundreds or thousands of rectangles.

Having seen your post, I tried ‘L=2’ and discovered to my horror that it returns **only three points instead of four!?!?** Naturally, the `Average` of three is different than four so the “center” points are all shifted.

‘L = 1’ *(tangency)* or ‘L = 3’ *(analytic)*:

‘L = 2’ *(curvature)*:

This could be bad. I have no idea why this is so? But will avoid using ‘L = 2’ like the plague.

Strange… I did some small tests before my first reply and I was having greatly fastest solutions with discontinuity (L=1) than simplify.

Can you attach your geometries? It will be interesting to try different methods…

Just use the Polygon Center component.
