Trying to move a sketch along a path

joshua.franklin · ‎02-20-2023

So I have a sketch that I made but unfortunately when I created it I put it on the wrong plane. Unfortunately its not just simple perpendicular plane. It is in a path that is 14 degree in one direction and 6 degrees in another. I would like to see if there is a way that i can move the sketch to the base plane that I have another sketch on(kind of like when you do a sweep/extrusion along a path. I have the path already created for the sweep extrusions that I need it moved along.

Can anything be done? Unfortunately this is something that is being designed from scratch and I'm trying to not have to 3D print this thing a bunch of times to get it to fit.

Long story short: Is there a move along a plane function? Thanks

Hi,

You can assign a sketch to another plane. But then it must be positioned correctly on the path.

Please share the file.

Guenther I figured you would have a good reply for me lol.

I am making sure as I design going forward that I am using a logical sequence of events to design. I am actually redoing the design that you helped me with due to a couple things I didn't like.

Also I did perform an import of a DWG file that I created off of a photo so it would line up on the mating part. that is why I have all of the white dots but that is another story all together.

Can you explain how you created this?

Your sketch is highly under constrained and under dimensioned. As such it is very easy to destroy by accident.

Also, is there a particular reason you have the timeline disabled?

As far as the base CAD sketch, it was done in AutoCAD off of 1:1 scan so it would match the contours, then that .DWG was uploaded and used as the base layer. I am then just trying to make a somewhat simple extrusion that has some simple but weird geometry's. I'm not a very avid 3D model person so I am using my 2d mind to try and back my way into what I need. I am then 3D printing a model to fit it up and see how it works on the bike. I have then had to modify the model as appropriate to fit the application. Each time I fit it up I see how I need to re-evaluate how the design is done. I am a novice at best but I do know what I am looking for so I just keep plugging away. as far as constraints I have a no formal training so I suspect I am probably not doing this right at all, I'm just plugging along until I get what I am looking for...eventually 🙂

Timeline; well its seems to be disabled every time I reopen Fusion 360, Not sure why it used to always be up but now it doesn't appear. I turned it on once recently but if I save and close the program it goes away.

I just opened an older file and the timeline was there. I suspect it has something to do with the fact that the very first thing I did was upload the DWG file with all of it weirdness. That's all I can think of.

In that case I would recommend to apply the fix constraint to all the sketch objects.

That way you cannot accidently pull things out of position.

You can do all of this natively in Fusion 360 - no need for import of dwg.

In Fusion you place the Image on a Canvas, scale and move to logical location to the Origin.

Then create your sketch(es) with Timeline on and Parametric dimensions and constraints.

When you import geometry you must turn on Capture Design History.

This is particularly important when working with geometry from a photo because of parallax error there will numerous edits that need to be made. For example - there are numerous locations where there are curves overlapping curves rather than ending at a Tangent coincident connection.

There are arcs that are illogical radii that I would expect to be one arc...

or at least logical radii and Tangent...

With history turn on you can Redefine Sketch Plane...

By the way - if you read the forum description at the top of the page - you will see that this area of the forum is for posting bugs (I know - the title is confusing).

You should be posting questions like this over here...

You probably feel more comfortable using AutoCAD.

To get comfortable using Fusion you simply need more practice - I recommend starting this project over using only Fusion and importing your canvas. Ask lots of questions.

I started out on the shop floor as a machinist the first 8 years of my career before moving into design, so working in 3D (just like on the shop floor machining real 3D geometry) came naturally to me. Once you get the hang of Fusion and 3D digital twin of the real world - you will never look back.

Thanks for the advice on doing the image directly in Fusion. I will try that. I do know that some of the radii are weird but that is because I was just following the path of the part.

@joshua.franklin

You are following an imprecise picture.

When I use an image I also use Calipers to measure critical dimensions and engineering/manufacturing experience to arrive at the true Design Intent.

When you attempt a project using an image Canvas in Fusion - I recommend that you Attach your file here to get instruction on how to Calibrate the image (understanding that nothing about an image is precise).
