I am wanting to write an application to create parts automatically in SW.  I am not using the common languages for this (VB, C++,C#), my language is Object Pascal (Delphi).  I have looked over the API help and have been successful in instantiating an OLE object for the Sldworks.application and started a NewPart.  I am not sure how to select a plane, create a sketch and then extrude, etc. the sketch into the solid part.  Would someone be so kind as to give some guidance with this.  In particular, if someone has done this in Delphi, that would be very helpful.
