To create the front vertical plane - Fig. c select the LINE icon and draw Start point Intersection icon of pt1 Next point @0 0 45 R pt9 Next point @60 0 0 R pt10 Next point Intersection icon of pt2 Next point right-click and Enter With the LINE icon draw Start point Intersection of pt9 Next point Intersection of pt8 then right-click Enter LINE icon again Start point Intersection of pt10 Next point Perpendicular to line 78 pt11 Next point right-click and Enter and first sloped plane created - Fig. d To create the second sloped plane - Fig. e select the LINE icon and draw Start point Intersection of pt10 Next point @0 80 0 R pt12 Next point Perpendicular to line 23 pt13 Next point right-click and Enter - Fig. e To completing the model three lines require to be added so with the LINE icon draw a from pt3 to pt6 b from pt7 to pt13 c from pt11 to pt12 The completed model is displayed in Fig. f on its base . the standard sheet black border. At this stage save the model as a drawing file with the name C MODR2004 3DWFM or your named folder 26 Modelling with AutoCAD 2004 11 Note The model has been created using 3D co-ordinate input with the WCS . no attempt has been made to use the UCS. This is a perfectly valid method of creating wire-frame models but difficulty can be .
