Releasing the left mouse button without selecting a p-point leaves the current set of p-points visible; you are able to zoom or pan the view, or quit out of the command line by clicking
Cancel on the
Status window.
In the latter case, identifying a length of implied tube causes only the Branches Head and Tail p-points to be made visible. Lines generated by a section plane (refer to
Section Planes for further information) are assigned to the significant element and not to the primitive sectioned; picking on one of these lines causes all the p-points of the significant element to be made visible - even when in ‘Design primitives’ mode. P-points that lie outside the view rectangle do not display.
