conform objects on a spline to surface

Hey

Im very new to Fusion and I would like to create something like this, where the red circles are bolt caps:

I would share the model but I cant export it:

Thanks

You should export it as a .f3d file, which is the Fusion 360 native format 😉

Okey. also is there any way to cap the hole on the bolt cap?

Since none of the Sketches or Bodies have been named, I'm left guessing on what is meant by "hole" or "bolt cap".    If you're talking about making the half dome a solid Body with a flat Face connecting its Edge, enter the Patch Workspace > Create > Patch > Select Edge > then Stitch.

Attaching photos in-post makes everything much easier- just click the Photos button above the text window.Cap What..JPG

Sure- see the attached screencast.    Also, attend to the errors in your Timeline NOW before proceeding any further- these are  like bombs ticking away, waiting to blow up much more work down the road.

Thanks it worked now!

Can you please show the proper way to align bolt caps on a line. Ive attached another scene. You can see there, that the bolt caps are tilted and have gaps. Im using "Pattern on Path" option to do this.

There are a bunch of ways to do this- I'll describe a couple, see if any of those meet your needs.

If you just need the cap to be part of the surface with no undercuts and aren't concerned with minor deviations due to differences in the surface curve being conformed to, consider applying Model>Modify>Pull to the underside of the cap to extend the part far enough to be fully 'submerged' in Body 5. (again, dude- name your stuff)

You can move the parts manually using the... wait for it... wait for it...  the Move command- M on the keyboard.   When you do so, lasso-selecting the button will center the control point on the Body- if you just click on the Body to select it, you'll end up moving the part around wherever you clicked, which may displace it from a common space the other caps are aligned to.

There are other methods for precisely locating these parts, but all require much more consideration and time.

Again, fix those Yellow and RED warnings in your time line- right click on the Feature and select "Review Warning"; start with the oldest Feature first.   If you don't do this now, you will weep later.

Is there an option to align by normal?

If by "normal" you mean relative to the curved surface of your part -not that I know of.   Most automatic alignment in Fusion relate to Points, or regular Planar Faces- so when employing Move or Align- or Joints, for that matter -Fusion will need a reference.    Your options here include using Lines/Splines along the plane the caps are oriented on, then creating a Plane Along Path on those to place a Sketch, then a Point to snap to- for each and every cap.   Fun, huh?

Am I getting something wrong? What's about Create-> Pattern -> Pattern on Path?

Kinda fun...Im a professional 3ds max user, so im thinking in 3ds terminology and trying to use the same approach here, though  Fusion is like learning to walk again..

"Pattern on path" doesnt work as it suppose to.

It occurs to me it would be easiest to just make the cap bigger and create another path Offset from the first far enough to allow for full contact.

Doesn't it?   It's "Pattern On Path" not "Pattern on Surface".    Is the cap not tangent to the path?

Ha!   The problem is the orientation of the Body used for the pattern- it's not oriented to the path at all!

Ive got a spline curve that follows\conforms the surface, so yeah, the caps are not tangent.

Hmmm its suppose to be a references body, is it not?

Do you see anything in the Pattern on Path dialog that references a Body or Surface guide?    It's changing the orientation of the Body to the Path based on the Body's original orientation.     The body could be shaped like anything- say, an avocado -it would use the initial relationship to the Path for the orientation of the iterations.  You're going to need to extend the curve of the Construction Spline so that you can position the cap tangent to the curve.
