Other than that, remember it’s Z-axis-only so you might need to transform your model to make it work. There’s also an option to close your spline & create tubular slices. The output slice is more dependent on the resolution of the polyline & the number of cells in your model though. There are almost no settings to play with – just a tolerance for how closely the slice follows the polyline. ParaView will extrude the polyline along the Z-axis (in both directions) & produce your lovely wiggly slice ? Top Tip: Use a 2D view along the Z-axis to make things a little easier.Īdd the Slice Along Polyline filter – set the Dataset to whatever you’d like to slice & set Poly Line to your wavy new source. Well you can ? I’m not sure why you might need to do this, but it can be done – with the caveat that it only slices in the Z-direction.Ĭreate a poly line source (Source > Geometric > Poly Line Source or SplineSource) - add points either by clicking or dragging them around in the window (you can type them in too if you need them to be precise). Slice Along Polylineĭid you know you can create a wiggly slice based on a polyline? So, at the risk of all of my emails turning into “three tip” collections, here are three bits of ParaView esoterica that you can play with today. You’re very unlikely to break anything & extremely likely to learn something. ParaView is one of those tools that rewards time spent playing with it – clicking all the buttons & poking around to see what happens. It’s Robin from CFD Engine & I’m recovering from my epic battle with snappyHexMesh by taking a break in ParaView-land.
