Tutorial by Sudhir Gill
Small

This tutorial mainly focus on using a image file to model a spark plug. I am no expert in SolidEdge but if you encounter any problem while performing any step let me know. I will help you in all possible ways.
The required Drawing file is attached with the model (Spark Plug) and also with the Question.

  1. Step 1:

    Start SolidEdge in ISO Part mode. The tutorial is made in Synchronous Mode but will work same for ordered.

    Adjust it so that the center line is at origin.

  9. Step 9:

    Select line tool.

  10. Step 10:

    With snapped to the X axis start making line.

  45. Step 45:

    Make lines.

  46. Step 46:

    Make vertical line so as to pass the virtual center axis of the plug.

  47. Step 47:

    Goto the left side and start making the line.

  48. Step 48:

    Pass it through the whole image.

  49. Step 49:
