Hello.
I'm trying to make a shape with Loft command, but when I choose the path/guides it says "The selected entities are not valid" this is weird because I'm using a polyline as a patch. The HELP section says a polyline 2D/3D can be used. (Objects That Can Be Used as a Loft Path). I explode the polyline and I use arc and lines as guides and nothing happen either. I have to perform the whole Loft shape by steps in order to complete it, but I would to know how to do it without have to do it in long way. Somebody know why this happen? I left a link with a video what I'm saying. In fact, I left the file in case somebody wanna check it out. Thanks.
I'll appreciate your help.

Solved by nestly2. Go to Solution.
The polyline fails as a path because it does not maintain tangency between the arc segment and the straight segment at the transition between FormB and FormC
Thanks nestly2. I used your advice making a new drawing. I did the pacth with parametric constrain (tangent) and I reorganized the forms moving them point by point and then I apply the Loft command. It worked very well this time. Thanks again.

If you encounter something like this in the future, it may be quicker to use the FILLET command to make sure tangency exists.
