This is my first attempt at using loft… I’ve read the manual, watched the YouTubes and I’m still not able to successfully complete my design. I keep getting the error in the subject line when I try to apply the guide curves. Since I’m a new user I’m unable to upload the sample file I created. Hope someone can refer me to a reference.

Thanks

I was able to upload. It’s a very simple sketch. Hopefully someone can educate me as to where I am going wrong.

Hey, now you should be able to upload your design.

Thanks! I’ll give it a try in a few minutes.

Hello Rtk,  
I tried with your curves. The problem was there, as showed in the pictures :

I unlocked the points, moved them to cross the circle, and the loft worked fine.

Hi,  
@Atelier said it all. I was doing a video at the same time to show you.  
Guided Loft has no tolerance at all for the guide. They must be absolutely connected to the surface.  
The best way to be sure is to move each point a little and put them back, ensuring both the guide and the surface boundary blink.

Thanks so much!!! My big learning for today. I’m going to go practice right now.

Thanks again.
