1.I tried to loft these two bodies, but the outcome was different from the sketch in the drawing. what is the right approach?
2.Also even when everything was symmetric the lofted body was not, so I had to manually move the connections points in order to make the body symmetric. Is it the normal way or am I missing something?
I believe you need 2 more guide curves perpendicular to the ones you have in order to get the desired result. You will need 3d sketches to draw them.
I haven't thought about 3d sketches at all! I give it a try.
It is very annoying to work with 3d sketches and have perfect symmetry. My advice is to make the loft, cut the model in the middle and mirror it as a body to get the perfect symmetry, Good luck.
Sorry for the delay. Yes, if you create the guide curve for the left side with a 3d sketch you will see that you can't mirror it. What I usually do is make the loft and then cut the part in half and mirror the body in order to get perfect symmetry.
So what you mean is to cut whatever I get after loft and use one of the halves to mirror and get the the perfect shaped body?
