Lofting issue. Unable to select the sketch to create loft

[Anonymous]

I'm new to Inventor.  So I'm playing around with designing an RC plane and in the middle of creating the nose for the plane and are hitting these challenges.  I can't figure out how to create a loft between the back sketch connecting to the front nose since Inventor wouldn't let me select the sketch on the back.  I checked everything to make sure that I have all lines connected appropriately but Inventos still won't let me create the loft.  Any suggestion?  Please help?

Your sketch had some profile issues.  Use the Close Loop function, or Sketch Doctor, to find these and make the loop continuous.  Take a look at the screencast.  Edit the sketch and then right click on one of the sketch entities then select Close Loop from the context menu.

OMG John.

You are amazing.  Thank you so much for answering my question with the video.  That's the best way for me to learn and you hit the point to the dot.  I really appreciate you spending your valuable time educating me on this problem resolution.  Thank you so much again and have a wonderful day/evening wherever you are.

BTW.  Moving from one sketch to another is absolutely a struggle for me with the spline or line not intersecting with the others.  Is there a best practice that I can follow in order for the line to just connect when it got created.  Every time I was done with the sketching and trying to loft it, I'm always faced with the same error of line not intersecting.  Have to run the whole close-loop just to hunt for the line that's not intersecting.  Is it just the way it is?  Coming from Solidworks, it's easier for me to find which line that's not intersecting and all I need to do is to click the two-line and tell it to intersect and it's done.  I'm liking the Inventor because it can let me get the job done and not needing a huge resource to do it.  My current desktop with crappy video card but 16gb ram do just fine for Inventor but it's slow as molasses for Solidworks.  Thus I'm learning how to use the inventor.  Am I missing something?  Please advise?
