does anyone know what is this ,or how to make it a 3D model using inventor , it is confusing to me and am still a beginner so i hope someone could help
Ok what you have to imagine is that the Drawing has been split down the middle cutting the parts in half.to reconstruct them you have to trace the Part and then revolve the sketch around a middle axis. I have placed the part No 6 as in the drawing showing you how to do this. you need to practice doing this with other parts. Also I would recommend that you use YouTube to find out other methods you need to complete Safety valve.
