Hi,
<rant>
I keep forgetting how much tools (involving meshes) are still seriously broken.
For many years these have been broken. It’s 2014 now and splitting a planar mesh should be working.
Today I need to split off a lot of strips from planar meshes…Rhino just cannot handle this in any way!
I’m stuck and need to go though hoops to perform a simple task like that.
Please take your users and your software serious and fix this type of malfunctioning.
It’s 2014 (mesh)tools offered should work more than just half of the time.
Here is a simple example of a mesh not being split by a line:
SpliMeshWithCurve.3dm (179.8 KB)
EDIT: I just made this example file and found it’s even worse: the result is … well see for yourself:
PLEASE PLEASE PLEASE
Invest in fixing these longstanding issues with obviously broken tools.
If I were in the position to choose a 3D-modeling tool without prior knowledge about Rhino, and ran into this type of alpha-quality tools for Meshes (not NURBS but straight forward Polygon Meshes). I would feel not much confidence in the software. I’d suspect if a company dares to ship software with tools this broken they must fall short in other areas too.
In 2014 a modeling package should be able to handle Meshes correct for all simple operations it offers.
Either fix these broken tools or be honest to us, to yourself and admit you are not up to offering this type of functionality and remove them from Rhino.
On the What’s new in V6 page, have a list of tools that have been removed to make Rhino more reliable.
TL;DR
Let’s be honest, the current state of many (mesh) tools is laughable.

Thanks for reading

Update:
I got this to work by not using SplitMeshWithCurve but just MeshSplit then the split seems correct.
Update:
MeshSplit is also broken…MeshSplitFail.3dm (109.9 KB)
Update:
I git this to work by Extruding the (poly)curves and using the Extrusions to split the Meshes
BE AWARE when doing this with curved surfaces:
For splitting this way, the rendermesh is used, not the Nurbs surface.
