how to make a line tangent to spline

[Anonymous]

I cannot make a line tangent to a spline.  Is there a workaround?

Attached is a simple example of a fully constrained spline I need to make tangent to a vertical line.

Thanks.

@TrippyLighting - completely agree that this request is justified, and even important.  However, as you well know, there are LOTS of important and justified requests for Fusion.  Eventually, we will get to them all.

And, thanks for being willing to illustrate a way to achieve this using existing tools.

I would be interested to see how you accomplish that.

Just jumping in for the notifications.

Hi Mr LoveThePirk,

Consider:

1. Draw any 2D/3D curve

2. Create a construction plane -  planeOnPath (via UI or API)

3.Normal to the plane at it's origin will be tangent to the curve.

4. It can be accessed using different methods: via sketch, construction axis,...

5. When basic rules are not broken it will be fully parametric also

Hi Mr Steve Ritter,

This is from the past, but still it might have some value to your F360 endeavors.

Hi,

I show my method in the screencast.

Nice!

Define affordable?

When you spend hours trying to get something to work in fusion where in solidworks it just works in minutes, then its really not that affordable.

I find myself spending more time doing work arounds than anything else, or waiting for fusion to update because I confused it doing something that should be second nature.

I cannot complain to much because as a hobbyist I am not paying for this, but I do use it at work too and they do pay for it. I am really very close to just forgetting fusion all together and go solidworks. Spend some more money up front, but at least you get a software that doesn't seem to be adding new features instead of fixing the already existing problems first. In the long run, the time saved, you might actually end up spending less money on solidworks.

Autodesk published this sometime last year.

Perhaps it not new, it looks the same as Jeff's method earlier in the thread.

Correct!

But thanks for providing the link.

I would love if this were to be fixed. I run into this issue not infrequently.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

It probably would be best to start a new discussion thread with a link back to this thread as reference.

I'll echo other repliers here - this is yet another example of simple functionality missing from Fusion. Many people may not bother complaining about these missing features...they just move along to other CAD platforms. As a professional user I can say I would NEVER recommend Fusion to anyone other than a hobbyist due to missing basic functionality such as this. All of the "solutions" shown in this thread are complex and burdensome, and I'm not sure any of them would actually work for me since I'm working off of projected and offset geometry. I certainly can't add a spline point in the right location since I don't know what that location is, and it's on another sketch anyways. 

In short, please renew some focus on adding these missing functionalities rather than developing new features. 

[lqg5960]

I already finished the project, it wasn't going into production anyways.

[lqg5960]

It annoys me so much. It feels like in nearly every project I find some new thing that seems like I should be able to do but can't, or the way I have to do it in fusion is insane and not easily adjustable. Then I look at the forums, and somebody else brought up the issue like 3-5 years ago, and Autodesk is just like, "It's not a priority," and the problem still persists.

I know I am in the minority, and this is a minor issue, but the fact that Fusion does not respect that some people want to have their scroll direction inverted, unlike every other app, including Adobe products that I switch back and forth between, infuriates me to no end. It's also a basic UI feature and I am pretty certain that this could be fixed in a couple of hours tops by adding a setting that literally just inverts the input when panning. It confuses me further because Fusion does have a setting for inverting the zoom direction. I have a feeling they will never add this basic QoL stuff, and their suggestion forums are all locked.

[jlarsonLP454]

Agree 100%. Every time I go to do something new I find another bug, missing basic functionality, or overly difficult workflow (having to use a text command to highlight unconstrained sketch elements, and it often being very unclear what's unconstrained about them since they won't move when I drag them, is one good example). Always something that seems pretty basic and easy to code up a fix for (how about a button instead of a text command for showing unconstrained elements?) that was brought up half a decade ago on these forums. Frustrating.

Like your zoom direction request, I would like to be able to program my mouse buttons for panning and rotating, instead of having to select between discrete options - basic settings in any other CAD program.

Anyways, I'll stop complaining, but I hope whoever at Autodesk monitors these forums starts paying attention to these comments and issues - I can see some of these basic functionality requests slipping through the cracks or truly not being a big enough issue to devote the time to, but the examples are so numerous it makes it pretty clear that your company doesn't value the fundamentals and would rather focus on what's new and flashy. Makes some sense for the hobbyist market, where users don't typically know any better, but it's a giant red flag for people who use CAD for their daily work and have experience with other programs.

+1 to implementing this feature. Seems like this is pretty basic functionality.

I'm pretty sure even freecad can do this...
