problem

[stefano apostoli]

Good morning guys use inventor recently and I have some problems.
1 When I create a sketch the face no longer aligns parallel to the screen.
2 is there a more precise orbit to rotate the pieces?
3 Should I build a flange that in the upper part is a little rounded? What do I use the spline? but I cannot quote it. . .
4 together I do not understand the difference between binding 2 pieces or joining 2 pieces.

Thank you.
a thousand to all stefano

1) application options --> sketch card --> check " sketch plan view to sketch creation "

too many questions together remain indigestive.
read the rules of the inventor forum and remember that it is good to open a discussion for each topic, however, for the first question has already answered you stefanobruno, for the second:
if by more precise orbit you mean around a axis, next to the orbit command there is a dart, expand and choose " bound orbit".
for the third: open another discussion, hope better what your problem is and, better still attach the file
