Design disappears after extruding

[Anonymous]

My design keeps disappearing after I extrude a part of it and it has multiple parts and have to extrude them different distances. This is after I import my SVG onto an object and then have to extrude. Any reason why this would be happening? A video is attached of this happening. Any help is appreciated. Thank you!

it's a little hard to see what's going on in that video.  Is it the sketch disappearing that you are asking about?  If so, just click on the lightbulb icon in the component browser on the left to turn it back on.

Can you share the model here (export it as F3D, and attach it to the post).  Also, if you want better quality videos, I would recommend screencast.  It's a really useful tool for recording application interactions.

Am doing a 2nd version of flat plate 6mm thick by 120mm by 130mm with 3 vertical dividers 90mm high ,6mm, 6mm and 12mm thick, when I extrude the center one AOK, the 2nd looks ok at first I enter 90mm high the carriage return and the extrusion disappears. RG.  By the way Fusion 360 is really unstable in reference to Word 2013, Xcel 2013, Paint 2013, NotWorthy Composer 2, these programs are very stable and straight forward with no Weird problem, Fusion 360 is great when it works when I export Meshmixer (WHICH ALSO SOMETIME CRASHES) opens and all I have to do is open the resulting file with KIDI TECH. Happy New Year..RE.

Can you File>Export and then Attach your *.f3d file here that exhibits this behavior?

Just adding that I'm a new user and seeing exactly the same behaviour.  Imagine I create 3 2D rectangles next to each other because I want to create a "Olympics medal podium" by extracting these by shapes 2inches, 4 inches, 3inches respectively.  I select the first shape, extrude it 2 inches and get a box - but the other two shapes just vanish!

[paul_d_smithMNY]

And found the answer.  From your account (top-right), Preferences, Design, uncheck "Auto hide sketch on feature creation".  Seems like a bizarre option to me!

[jeff_strater]

why do you think that is bizarre?  I would guess that 90% of people create a sketch, consume it, and never use it again.  So auto-hiding it makes sense in that workflow.  Also, every other CAD tool that I know of auto-hides a sketch on consumption by default.

[paul_d_smithMNY]

Because I was creating a complex component that I sketched out as multiple elements, extruded each separately and then rotated and pieced them together to create the whole component.  But when I extruded part #1, my careful designs for parts 2, 3... all vanished.

Hi,

Please check if the sketches in timeline are behind the extrusion process.

If you then want to edit the extrusion, you will find yourself at a point in time where the sketches did not yet exist.

Please share the file and show your proccess in a screencast.

Sketch visibility can easily be toggled On/Off in the browser.

All of the experts I know use this technique as needed. (This includes Creo, SolidWorks, Autodesk Inventor Professional and Fusion 360 users.)

[jeff_strater]

Fusion does not know that this sketch was intended for parts 2, 3, and 4.  You can change that setting, certainly, but then all sketches will remain visible until you specifically turn them off.  Nothing wrong with that workflow, but most users prefer the auto-hide.

[paul_d_smithMNY]

Fair enough.  Do you have any suggestions for sites where I could learn how to do what I want without using this technique?  Here's an example of the problem I want to solve.
Imagine I want to create a piece that is three different sized, stacked shapes, one with a hole through the X axis, one through the Y and one through the Z.

Using the "layout, extrude, rotate/join, it's easy to centre/place the holes and then extrude "part piece with hole" but how else could I do this?

Thanks for any suggestions - very new to this and there are normally different ways to "skin the cat".

No need to merely imagine.  Create what you want using any techniques that you can, then ...

Sketch and first Extrusion) then simply hand sketch or post image to something similar that already exists in the real world.

[paul_d_smithMNY]

This is the object I created.  The base was sketched as three "parts" next to each other, each extruded independently and the uprights/pivots were an additional part that I extruded, then rotated and moved to join to the (after extrusions) base.

This will be an easy one.  That can be done with a single sketch.

Double click on the sketch dimensions to change to your design.  (See Attached 15 min example.)

@paul_d_smithMNY 

Did you figure out how to toggle the visibility of sketches?

[paul_d_smithMNY]

One minor mistake - the back "pivot" should be from 1/2 to 3/4 back from the front.  The spacing is pivot, blank, pivot, blank (effectively two of these can be connected together to produce a clamp).  However I doubt that changes much in the design.

I'll take a look when I get a little time (work, family etc... also expect some of my time - how unreasonable of them 😉 ) and see how I get from your sketch to 3D.  This was my first attempt so there is plenty for me to learn as to how to achieve something like this.

Many thanks for your help and guidance.

🙄All I had to go on was a pretty picture.

For future reference you should always Attach your *.f3d file along with problem description.

If you have any trouble figuring out my model or how to fix your model - post back.

I didn't necessarily use the technique that I would actually use - I just wanted to demonstrate that the model can be made from one sketch.  Usually it is better to use several sketches (some would advise one sketch per feature) but this model was so simple I demonstrated with one sketch.

[robert_sprecher]

Bizarre indeed. Beat my head against the wall for 3 hours trying to figure this out. Thanks for the simple solution.
