You may have different PH and PV handle numbers. b layer PH-70 has HIDDEN linetype as this linetype was loaded in step 8 The top right viewport will display visible and hidden lines for the model Make the lower right viewport active still with layer 0 current At the command line enter SOLPROF R and a pick the model then right-click b enter Y R to the display hidden profile lines prompt c enter Y R to the project profile lines prompt d enter Y R to the delete tangential edges prompt e layer properties manager dialogue box and 1. two new layers PH-76 and PV-76 2. freeze layer MODEL in current viewport 3. pick OK The viewport will display the visible and hidden detail lines for the model in the viewport At this stage the layout should resemble Fig. and can now be saved if required but not as SLIPBL This exercise is now complete.
