Simplify curve. Keep features

Obviously a bounding box wouldn´t help as I need to keep the orientation

There are several solutions on the forum for computing plane aligned bounding boxes that might help. Here’s an example I wrote, implemented here to find the smallest area bounding box for a planar polyline in the XY plane:

Also, it’s good the upload a file when posting. And welcome

Edit: Depending on requirements, these polyline “simplification” methods might also be relevant:

Combine similar segments in polyline

The Polyline class also has several methods that might be relevant: https://developer.rhino3d.com/wip/api/RhinoCommon/html/M_Rhino_Geometry_Polyline_MergeColinearSegments.htm https://developer.rhino3d.com/wip/api/RhinoCommon/html/M_Rhino_Geometry_Polyline_RemoveNearlyEqualSubsequentPoints.htm https://developer.rhino3d.com/wip/api/RhinoCommon/html/M_Rhino_Geometry_Polyline_DeleteShortSegments.htm https://developer.rhino3d.com/wip/api/RhinoCommon/html/M_Rhino_Geometry_Polyline_CollapseShortSeg…
