### Surface Modeling - A Designer Lounge Part 1 of 2

 In this tutorial you learn:   How to model a Designer Lounge using the new BlueSurf command of Solid Edge How to use the BlueSurf command How to use Extruded Surface How to project curves onto surfaces How to trim surfaces How to use derived curves How to stitch surfaces Thicken surfaces to make solids
 Drawing the profile - Side View Start with creating a curve in a plane parallel to the y-z plane. Using the Curve      tool, create the outline of the side of the lounge. See figure. More profiles Create another curve in the x-y plane. More profiles - top view Constrain the end-point of the curve to the end of the earlier curve. Cross Curve Select the Cross Curve command from the Surfacing toolbar as shown. Select Curves Select the first curve as shown in figure. Click accept      on the ribbon bar. Select the second curve as shown. Click accept      on the ribbon bar. Click Finish on the ribbon bar. Soon the cross curve is formed. The cross curve is neither in the top plane nor in the side plane. It travels in 3D space, giving us the desired edge to create the back-rest. Mirror the cross curve Mirror the Cross Curve about the y-z plane as shown. Connect the cross curves In a plane parallel to the x-y plane, create a line in two parts as shown in figure. Connect the endpoints of the line to the cross curve. Make the lines tangent to the cross curves. Parallel Plane Create a plane parallel to the x-z plane such that it passes through the end-points of the cross curves. See figure. More Curves Create two curves in the new plane as shown in figure. More Curves - Front View The curves as seen from the front view are shown in figure. They are a curve mirrored about the y-z plane and well connected to the cross curves. More More Curves - Top View Create another curve in a plane parallel to the x-y plane and passing through the bottom end-points of the earlier curves as shown in figure. More More More Curves Create yet another curve in y-z plane. Connect this curve to the bottom and top curve wherever the curve meets other curves See figure. Derived Curves Click the Derived Curved      tool on the surfacing toolbar.Select all curves along the top and the curve at the bottom till they meet the vertical curve drawn in last step. See figure. Click accept    on the ribbon bar. Derived Curves - Once More Similarly, create derived curves on the other side. The BlueSurf - First Curve Click the BlueSurf      tool on the surfacing toolbar.Select the curve as shown in figure. Click accept    on the ribbon bar. The BlueSurf - Second Curve Select the curve in the middle and click accept    on the ribbon bar. Both - correct and incorrect - ways of picking the second curve are shown in figure. Pick in the correct way. Continued to Part 2...
