Working with 3D Sketches

[docara]

Hello

I'm just working on a 3d sketch and found that I am unable to dimension or fillet line(s) away from the originally chosen sketch plane.

If you notice in the enclosed file I have proceeded around dimensioning and filleting the lines as necessary and come to an abrupt halt where the lines goes 'vertical' - how do I do it or is this a limitation of the command

Thanks

When I look at this - I see the Projected Intersection of 2 simple (and easy to dimension/control) 2D sketches.

For your Design Intent - would this work?

Hi 

Yeah! I'll try that good idea, but my original question still stands.

The profile was drawn continuously around a 3D Cube to make sure each section was in the correct plane then was being dimensioned unbtil Fusion said no - you would have thought it would be able to handle an edit to 3D line(s)

My intend was to use this continuous sketch as a path with the PIPE or SWEEP commands.

I'm  struggling!!

It seems the only way to achieve what I want to do is to define a cube and project the relevant edges to use as a guide for the 3d Sketch. Using this method I was able to do fillets between all corners.

To change the dimensions of the 3d Sketch I had to EDIT the original 2D rectangle sketch and if I wanted to edit the third dimension I had to use the edit the Extruded Feature via the Timeline. 

Firiggin' ridiculous! Surely this can't be the way the to do this sort of thing - can it???

Fusion either needs some sort of 3DLine command or a way to select a plane/face on the fly if it is.

3D sketches in Fusion 360 cannot be dimensioned.t There are other limitations and bugs as well when working with 3D sketches.

Thank you Peter

Further to my original question I found this on Youtube

3D Sketch

It shows how to use techniques to draw lines off the chosen plane I couldn't help feeling it highlights how 'clunky' the command is - for example having to use the Move command to draw off the plane, or having to utilise a Point to aim for is just madness. Give us a 3DLine which bypasses the plane/face draw criteria soo much easier

For a layout as simple as this one it can be done as a 3d sketch but you need to know all sizes as you can't edit once created.

I have worked on 3D sketching  for chassis designing . 

First I created a line skeleton By Adding points . Means I had all my dimensions so If there is line I used to plot points and connect them .

Any news how 3D sketching is going to be improved in future releases?

Hello all,

Thank you for posting the queries. We understand that currently there are limitations in sketch when it comes to 3D sketch.

But, I can assure you that we are working towards 3D Sketch. It is a big project so it's difficult to put timeline just now. But, we are definitely working towards it.

Please feel free to reach out at my work email rohit.bapat@autodesk.com if you have any questions or concerns. We would love to hear any suggestions or questions.

Thank you for you patience and support.

Thank you,

Best Regards

I realize this is an old thread, but thought somebody might be helped out by this:

1. When the desired outcome is relatively orthagonal in nature, as is the OP's situation in this thread, it's often both easier and more user-friendly to use a few different 2D sketches instead of one 3D sketch.

2. Depending on the complexity of the desired outcome, it may be easier to make a sacrificial body/component from which the edges can be selected as the path. I'll demonstrate in the following video:

In Solidworks you can change dimensions afterwards witch makes a life a lot easier in 3D sketching if you are just trying different designs when drawing. This is what Fusion should have also. Specially if you’re making buggy type frames etc. incl lot of tubes.

FWIW, the sketch team is even now working on 3D dimensions, and expanded 3D constraints!  Not sure when it will see the light of day, but definitely in progress!

Yeah, I know. @jeff_strater  said they're working on it. While you wait, call Dassault Systemes and price one seat of Solidworks.

Fusion 360 is a great software going to right directions and Mac OS native is a big plus for me. Had enough of Windows. Really happy to know that 3D sketching is taking a step forward.

Guess I will just go back to using my 2007 version Turbocad 3D that handles this flawlessly.
