  1. Surface A LOS E Auxiliary Views (Curved Edges) The same procedure (steps1-10) discussed before applies for curved edges. However, curved edges have no corners, so we take points on the curved edges and treat them like corners. The more points we take, the better the drawing of the Curved edges. Take the following examples. Surface A Draw a true shape of surface A ( i .e we need an auxiliary view where LOS is Perpendicular to surface A.

  10. Run //CE-WSINST Auxiliary View - http://faculty.kfupm.edu.sa/CE/almanasa/ - Run //CE-WSINST - Complete - Partial (1) Identify line of sight (2) Draw reference line (3) Project lines from each view (1) Create layers (1)  Choose color for projection. (2) Create layers (2)  Choose another color for point numbers. - Draw offset  Through (any distance) and choose point for RL 2 & RL 1 -

  11. - Choose layer for text  Give the Same Number on all layer - Go to Tool pull down  drafting setting  object snap  perpendicular - OR ONSAP  setting  perpendicular (SELECT) - Go to Construction layer (1) - Type DI (distance) or from the Tool bar add Inquiry bar & choose DI

  12. - Go perpendicular  Go offset same dist. up and draw - Extent line to new point  Give a point number as text. - For curved line choose PL commands to draw lines - Type PEDIT  Choose line (to show it smooth curve)  F - To change some lines to hidden . Modify  properties  Line type  hidden - Mirror Choose line  shift choose ….. specify 1st point 2nd point around the x-x line Enter
