Assign Duplicated Sketches Line (Same Corner) along a line or bar to form a Loft (Rib Setup)

Thank you!

@Anonymous - that is not what Align does.  Align is for moving bodies or components by selecting geometry on both, and moving them together.  I think what you want to do here is:

• edit each sketch
• use Project -> Intersect to project the intersection of the edge of that body into the sketch
• use Coincident to constrain the sketch point to the projected point

if you share the design, I can record a screencast

How much experience have you had in Fusion, and timeline modelling?

You can't align the sketches to something that does not exist.

The bar comes after the profiles.

The profiles all reside in one sketch.

Two sketches are empty.

Your profiles are all the same, are you sure you need loft.

Work like this will send the Loft tool berserk.

Do you have a pic of the design you are making?

you can make this work, but I agree with @davebYYPCU that this is probably not the easiest way to go.  The attached screencast shows:

1. moving the "bar" back before the sketches in the timeline
2. editing the one sketch with all the profiles
3. using Include 3D Geometry to get one edge of that bar into the sketch
4. using Move to select the sketch geometry and move it into approximate location
5. using the Coincident constraint to force one point on the profile to exactly line up with the included edge

but, there is a lot still wrong here.  The profiles are not constrained, so when using Coincident, they won't move together.

This would be much easier if you put each profile on a separate 2D sketch, on an offset plane.  Then, you could use the power of 2D sketching to more easily dimension and constrain each profile

not much, about 15 hours, I am learning

reviewing now, thank you!

I will try this, thank you

WOW, got it looking great now! thank you, for some reason I can not set the dimensions for the sketch, other than that this is perfect!

since you are saying your new, I thought I would point out a few things.

-as a rule of thumb, you want to construct objects (either sketches or bodies) at the location where they are suppose to end up.  using move to position will cause you problems.  These forums are full of examples of that.

-loft is finicky.  your sketches have to be constructed carefully.  "moving" a sketches into place won't achieve that most of the time.  

-this example doesn't require loft.  sweep would be more appropriate.  see attached.

brain fart.   just extrude it all in one go. see attached

I am going to modify the duplicated sketches to create a tapered shape

[davebYYPCU]

No.

that is just plain hard work.

Make separate sketches.

Make them where you need them.

if the Loft Tool is the way to go, 

Sketch the second, third,...  profiles as needed, where needed.

Back to the first effort, your profiles were in one sketch, and therefore dimensions don’t work,

with new 3d updated sketch tools, I stop here.

3d Cad modelling has no short cuts, proper preparation saves time, quick short cutting doesn’t. (Save time).  Clever preparation makes Fusion do the hard yards.

Alex,  you been cooped up too long, already?

You got a pic of what you are modelling?
