"Dean, no, just native snap features. Cylinders' end faces can be centre and quadrant snapped without having to have reference or construction circles overlaid. A cylinder's native quadrants aren't always orthogonal or normal to World WP, though, it can depend on how they were created. You can snap to the features (midpoints, divides, vertices) of a segment of a 3D polyline that you're still drawing, as you create them. 3D polylines go between snaps on different WPs, instead of projections of other WPs' snap points locked onto one."
Thanks Murray, that works great. (see attachment) the red lines are the 3d polylines snapped to the cylinders surface
