I'm stuck, need help from expert designing an object

[Anonymous]

Hi everyone,

first an foremost this is a nice community with lot of information I discovered yesterday while trying to bring to life my project.

I however am stuck and I need your help or at least comments to guide me to a nice and sweet solution 😛

As I'm not at home right, I will attach files later, but wanted to give you more context/info on my need in advance.

I soon be celebrating my 4th marriage anniversary and its a tradition to gift something related to an element or material.

For the 4th anniversary, it is wax. I reach out shapeways and they can 3D print wax even if its their beta stage with this material.

However they couldn't help me with designing what I would like to print and I need to submit a CAD file. And I do not have experience whatsoever in CAD.

So I decided to give it a go myself nontheless and followed steps to reach to the point where the design (an arabic callygraphy) is imported in SVG into Fusion with no problem (and thanks to youtube videos on that matter). 

My problem is rolling over this flat design on a cylinder (I wanted to do a vase out of it). As I've read here, this is not yet implemented on fusion so to speak (is the next maintenance bringing metal sheet officially ??). I've continue reading and found the add-in that would allow such operation. 

However, and I suspect the complex original design, I crashed Fusion twice. I guess there is too many spline points for fusion to handle AND the add-in (or metal sheet I've be reading about) would only allow to roll on half the cylinder and not create a complete cylinder out of the initial design.

Soooo.... with that said, what can I do else and/or who could help me ?

(again, attaching files later today).

Thanks a lot

Eric

Start here.

This thread shows how to simplify sketches with too many spline points.

Thank you.

However the first thread you mentionned is the one that talk later of the add-in i used, so been here 😉 

Unless you wanted me to read something more specific I would have passed by.

And for the second, I'm not sure how this would answer my need as I already have spline points. I do not need to convert something into spline points.

Unless you are telling me that the svg I import (created under inkscape) is not rendered as spline points ?

Thanks

Hi,

Could you please attach a picture of the final result you're trying to achieve

When you create a spline with lots of control points, it slows Fusion 360 down.  Redefining the splines using the mesh tools can make the splines with fewer control points.

I believe this is where my knowledge of CAD stops.  I will dig into that.

This is not the final result but i guess you'll get it.

The text as a cylinder.

Like this, 

In sheet metal, create flange for the circumference of the vase, cut a small section out of the circle

add a small extrude section to utilise the unfold command, then 

back to model space, extrude join the text, 

return to Sheet metal and refold the faces.

Might help...

This can be done with the sheet metal tool, but first the sketch needs to be simplified.

To answer one of your previous questions, no, the SVG curves that were imported are no longer splines.  When you import ANY curves from ANY source into fusion, fusion turns them in to garbage.  I don't know why, it just does.  Best practice is to redraw with fusion tools any imported curves.  You can sometimes get away with using imported curves without doing anything, but yours have way to many points.

It's not hard to trace over with splines to get a fresh drawing.  do focus on using as few points as possible.  With practice you will find you don't really need very many.

[laughingcreek]

well i'll be @davebYYPCU, my computer wasn't having it.  really didn't like that sketch.  did you put the flat section at one end, or in the middle like (guys whos name I forget) does?

[davebYYPCU]

My "Seam" is around the back, 

need a 20mm offset from the end of the graphic section at each end.  So graphic is centred.

Yeah Fusion chucked a few black screens at me, but I know now, not to click another thing until he/she comes back into the daylight.

Might help...

I've tried this road, but the result is still the certain amount of point that made my fusion crashed.

I will try again with fewer spline points. 

The results showed  is almost what I need, but I do not have metal sheet tool. I've ask access to it but have not yet been accepted.

Will the maintenance at the end of the week bring the tool live for everybody ?

Thanks.

[laughingcreek]

I believe sheet metal tool is available to everybody now.  You don't have it under the pull down tab labeled "model"?  If not you may consider asking in the support section about it.  I didn't have to do anything to get it, just showed up in a previous update not long ago.

Another question. It seems the design is only on half the cylinder.

To make the design to become the cylinder itself (and a complete one), using metal sheet I would have to split the design on 2 differents faces and roll them into the cylinder ?

[etfrench]

Are you saying you just want the design as a cylinder and you don't want the solid cylinder to be part of it and you also want the design to be continuous with no breaks?  If so, then make the outside circumference of the solid cylinder match the length of the design.  Once you have it wrapped around the solid cylinder following @davebYYPCU's instructions, use the Combine|Cut or Extrude|Cut to remove the solid cylinder.

[davebYYPCU]

It is your file, the text is 119mm long, the cylinder circumference is almost 160mm, 

to centre the text, used 20mm on each end, to position the seam.

Not right? Change sizes.

Sheet metal is for all now, you can swap in and out as you need.

[Anonymous]

yep sizes are not exact as of right now. Wanted the proof of concept first.

Thank you a lot for your help.

I will come back here, if I need more help, but I believe I can manage from what you told me.

[Anonymous]

yup. 

and thanks for the precision. Will try that.
