Is there something wrong with my design? Why can't I do loft?

[itcomes]

Hi people! I've done four sketches for lofting. Two for profiles and two for rails. They are all fully constrained. When I try to select sketches for lofting I can select only one for profile. Is there maybe something wrong with using circular pattern option the way i used it. Here is the file.

Hi Itcomes,

it depends on missing coincident constraints due the 2d pattern.

As a test of your sketches - try Extruding rather than Loft.

You will need to run the Sketch Doctor on your sketches.

HI!

The question is, your sketch is not a closed loop, not all the segments are connect between each other, some are connected with other construction lines.

You must have all connected to have a closed profile.

...also, - have you installed all Service Packs and Updates for your version of Inventor?

Do you have an image or url of a similar design?

Yes..i doubt that your intent was this...but that is all you have told us

Thank you all for your replies. This design is something that's from my head and yeah that wasn't my original intent hehe. Maybe it's better off without rails. The problem was just like you all said and I've fixed it.
