Interesting, are you hooking up a lot of events to track meshes?
Usually memory leaks are caused by event handlers not being cleaned.
Unfortunately there's no newer version of assimp net available.
Could you provide a stp file so we can do some test on it?
Obviously assimp does not fully support step file: https://github.com/assimp/assimp/issues/2000
You probably can try to use different importer like https://github.com/ixmilia/step and then convert to helixtoolkit components.
Try to disable dx 2d by setting Viewport3DX.EnableD2DRendering = false.
Please try with the latest nightly build.

If you want to do it with vertex shader, you have to heavily customize Helix toolkit source code.
