In the following surface modeling example, we will share a surface modeling of a gasoline bottle created in Siemens NX software. We will use a few simple curve and surface commands to create the shape of the bottle.
Create a sketch in the XY plane with the dimensions shown below and stretch it by 200mm;.
Create a sketch of the following dimensions on the XZ datum plane and rotate it to get a rotating body;
Use the “Isoparametric Curve” command to create a curve on the surface of the above rotating body (the curve is determined according to the position of the 8 points in the figure below).
Use the “Bridge Curve” command to create 8 bridge curves as shown below;
Use the “Through Curve Mesh” command to create a mesh surface as shown below;
Use the “Unite” command to combine the three individual bodies into a single body;
Use the “Edge Blend” command to create the rounded corners of the bottom edge of the bottle, R15mm.
Use the “shell” command to create the wall thickness of the bottle, the complete result is shown below;
