Sorry I didn't realize this is about Clipper class and I was using ClipperOffset, which is not in Clipper's class hierarchy. It's using a Clipper object as a local variable in ClipperOffset::Execute, I'd suggest to promote that local variable to a member variable and give public access to it, so a user can set its ZFillFunction as well it can be done with Clipper

As I read somewhere in the forum, Z isn't the 3d's z dimension, is an auxiliar storage member, can be used for example to store related vertex information as material IDs, or some kind of flags need to be propagated.

Same problem here...

It was finally added to version 6.4.2? I'm getting all z values set to 0 with #define use_xyz

I've been taking a look to the documentation and it seems that's not the expected behaviour, I'm wondering why, looked the code several times without any luck. Here is what I'm doing: ClipperOffset clpr; Paths input, solution; ///fill input clpr.Clear(); clpr.AddPaths(input, JoinType::jtMiter,...
