Plane normal to line at point

[salvatore13]

Hi guys, I'm struggling with creating a plane that would be normal to the path and placed at a certain point. The "Plane Along The Path" doesn't let me choose the point so it won't work. 

So on the below screenshot, you can see the edges at which I need to create number of sketches that are normal to the line and are at very specific points...

Hi,

are you looking for something like this?

This would get the job done for 2D line but the profile I'm working on is a intersection curve which means it's a 3D line without a simple sketch where I could do what you've shown here.

How are you determining the specific points?  Use that to position the plane on path.

[salvatore13]

the point's are projected on to the line from another sketch. This is a hydrofoil design so I want to make sure dimensions are on the spot. Also I could actually use the method shown above but this would render my spline geometry useless because it would be cut into pieces and editing wouldn't be possible anymore.

What you see there is done manually so the planes are created using "plane along the path" option roughly where the points are but this unfortunately won't update if I change the geometry.

and here is the final result

On a copy of the spline, cut it at the intersection points (starting at one end). Use the Measure tool to get the length of the remainder.  (Set the precision in Preferences to the maximum in order to get accurate measurements.) Use the length to set the distance of the Plane on Path.

Hi,

1. Maybe "Split Face" will create what you want.

2. Be careful when using so many profiles. Less is more.

If I understand the problem correctly you want planes perpendicular to the projection of the 3D curve?

The workflow in my screencast will create planes perpendicular to the projection of the curve, the planes will be positioned on points along the curve and only rotated along one axis (Y).

And you can update the spline and the planes will update.

@salvatore13 

Is something like this what you are after?

(I forgot to show at the end that it is fully parametric if I change the spline.)

@TheCADWhisperer This is exactly the functionality I'm after in Fusion 360, but doesn't seem to be possible.

1. There ought to be a plane type that is "normal to curve at point", which simply appears to be missing from the list of plane options.

2. The generic workplane tool you used in the Inventor example would be a much more efficient way to create planes. The type of plane is determined by the types of reference geometries selected, eliminating the need to identify which specific plane tool is needed. This approach also allows planes to be redefined as different types, rather than having to create a new plane and update all dependencies before deleting the old plane.

@KristianLaholm workaround is somewhat acceptable for 2D curves but doesn't really work for 3D curves.
