@Haocheng\_Liu I did eventually find the exact error I ran into with modelbuilder 6; in my case, modelbuilder would start but when the pqBehavior instance was requested or when a reader was created (I can’t recall which),… --- ## [Refactoring](https://discourse.kitware.com/t/refactoring/111)

@Bob\_Obara @tj.corona I haven’t used it, but the refactorial project — which uses clang’s libtooling library to perform refactors — might make it easier to do some of the larger class renames.

I recently started a branch that provides a uniform API for plugins to register things to different SMTK managers (currently resource::Manager and operation::Manager, but more to come!). The pattern I used requires the m… --- ## [Extending the auxiliary geometry extension](https://discourse.kitware.com/t/extending-the-auxiliary-geometry-extension/100)

@Haocheng\_Liu I see at least part of the problem you have with the RGG session. It needs not only to indicate that the .rgg file can be loaded but also to add it to the VTK cache. Since it adds dependencies beyond VTK, i… --- ## [Operation view](https://discourse.kitware.com/t/operation-view/94)

All, but especially @Bob\_Obara: I’ve got selections in modelbuilder generating a list of available operations and have come up with a few questions on the operation panel. Here’s what I’m planning: In real life, the… --- ## [Plugin loading](https://discourse.kitware.com/t/plugin-loading/92)

@tj.corona How do you feel about a test that dlopens/closes/opens/closes plugin libraries to verify that the crazy ParaView library thing doesn’t cause problems down the road? --- ## [Delaunay extension](https://discourse.kitware.com/t/delaunay-extension/88)

@tj.corona Shouldn’t there be an “environment” library for smtkDelaunayExt? I don’t see one and the tests appear to manually register the operator to an operation manager. --- ## [Homebrew on macos](https://discourse.kitware.com/t/homebrew-on-macos/75)

It’s come up that homebrew now only provides python3. Unless you have a previous homebrew python 2.7, there’s no way to build SMTK without building your own python.

In adding operations to modelbuilder v6, we want to improve on the drop-down list in v5. One thing we want to do is present operations that can be applied to the currently selected components.
