Problem with loft

Anonymous — Thu, 28 Jan 2016 09:36:50 GMT

Hi community

I have a problem with the loft feature in autodesk fusion 360. I get the error "wire has self-intersection" or "coedges in a contiguous sequence are not vertex connected" depending on how i try to make my loft. Becouse english is not my native language i simply do not undestand these errors. I gather that the first one means i have something that intersect with itself but thats all i undestand. The wierd thing is i can make a sweep but not a loft.

What i am trying to do is make a trumpet that starts of as a square and ends in a circle. I made two planes at an angle to one another and drew a circle and a line on each of them. The point in which the two line segments should join i made a point and snapped to this point from both planes. As long as i only try to loft in one plane it works fine but when i try to loft over two planes it gives me the errors.

You can find my design here http://a360.co/1nQIkXX

What am i doing wrong?

Thanks for your help.

Morten

It works if i uncheck chain selection when making the loft.

I thought this worked but it doesn't. I was able to make the loft in a new design file, but it seemed to be a lucky shot. I can not do it again.

Please share your design. You can do this by sharing a public link of the file from the data panel in Fusion 360, or export the file as an .f3d and attach it to your next post.

I think the problem was because you were using curves from 2 sketches as the centreline, I made a new sketch and used 3d project to copy the curves into 1 sketch and it seem to work.

File attached

First of all thx for you replies. Secondly sorry for my abstinence. Third in reply to HughesTooling:

What you have done is not quite what i wanted but it works. You have made one loft but you have 3 profiles that the loft goes through. When looking at you design the profile 2 should not be there. That being said i went in and deleted this profile and the loft still works. I see you have to include the 3d geometry from the first sketch in order to make the loft.

Thanks a bunch HughesTooling 🙂

I've received the same error "coedges in a contiguous sequence are not vertex connected" when trying to loft 2 different shapes without using a path or points. After multiple attempts with various different methods, I edited each shape and used the 'Pedit' command to join multiple lines, and was then able to loft both shapes without any problem.

It may not work in all situations, but the Pedit command seems to overcome most errors experienced through using loft or revolve.
