Hello everyone!
 
I'm a new member in this forum. I have the following difficulty which I'd like to discuss with you.
 
I'm trying to create a 3D **surface** model with Inventor 11 using the loft feature with rails and sections.  I'm having difficulties to get the rails touching exactly the sections.
 
Can you please tell me how I can snap the rails such that they are exactly on the sections?
 
Thanks in advance
 
Philip

You can use Coincident constraint in a sketch to snap to the endpoints.

Here's a quick tutorial on lofting that may help.
