Hi, thank you for all your instant feedback for all my comments. Here in this part, i can't able to generate sketched form at the end, I re did the sketch many times still can't able to generate, I can't able to find what's the issue, checked the google as well, nothing is mentioned about the tangent surface sketched form issue. (I did exactly like you did) I tried it in new cylindrical surface, it's not working..
Imported data show their own Front, Top & Right plane which result in isometric view (Ctrl+D) other than my requirement. Basically I want to avoid creating my own orientations.
Yes this is possible but for this you need to be careful while exporting data to iges or step. The orientation you have before exporting the data is the orientation after importing the data. So you need to correct orientation before exporting the data. If this is correct, you will get correct orientation after importing the data.
Our customer give vehicle fitment CAD data so it is not possible for us to change their orientation which was created on their softwares (NX/Catia). Can we do something else on our end?
