I think that with a Pro version at least, you can deform (maybe not going into surface) a volume. But I would rather make a polygonal roll to obtain the desired result insofar as the product will not be straightened.
It looks very similar to the problems of circle involutes in gears. I think you would like to read the literature on this. The big difference is that you have a soft thing between your two reels: so a deformation that can change when rotating your reels.
(NB: You can very well replace the " Surface-Plan1 + Thick1 " combo with a simple extruded sketch. It's just that I started my tests with surface and I kept this base).
2 animations. According to my movement study, it seems to work:
On the other hand, I didn't manage to do the bending in the first blue box " inflection input" I tried to put surface delete which corresponds to the end but Sw doesn't want the functions can't be selected So I'm stuck in the FLEXION function
Small bonus question: when I made the half egg as an attachment I used the Insert an image in the sketch function. When I do this in a row when I zoom in the 3D is no longer in the middle of the screen at all and knows quite annoying, did I do something incorrect or is it a bug of sw 2020
Under 2020 it is impossible for me to have 360°. Based on @Sylk for my test under SW2020, I cheated with 359.82° and 50mm radius then extrusion to close the cylinder:
So the problem is that your models are not on the aligned planes like I did. Not that it's bad, only then you have to adapt the position of the Trihedron.
For you, as it stands, you have to enter these values: X Rotation Angle: 180deg Rotation Angle Y: 90deg Z Rotation Angle: 90deg
Wouldn't you have skipped the step of removing the faces at the ends? Because it is precisely to be able to allow the complete 360 with auto stitching, that I added this step. Otherwise, the 360 is effectively refused.
I know you skipped the step, because the "bending input" should be "DeleteFace1" and not the "Boss-Ext1" But I admit that I could have given more details. I'll make a video tutorial.
There for "inflection input" you have to select the surface body "DeleteFace1" from the tree that is superimposed on the viewport.
But you will encounter a problem, invisible face once your flexion is validated.
You have to choose the top plane for the sketch of the plate, then extrude it but the bottom (reverse direction) so that the top plane is also the top of the plate.
Then if you keep this value of 50mm thick the side faces of the cylinder will be invisible (already better than the top face), so either you enter a value one notch below 50mm (49.99), or you leave 50 and fill the faces with the "filled area" function (I think, but my SW just crashed). This function makes me crash, so I suggest you put less than 50, then after your bending, simply merge another cylinder body barely larger than the diameter of the hole, to have a full and closed final volume.
For all intents and purposes, I will post my coin, as well as my parametric egg (a single value to touch to change its size). Here is already the egg: Egg.SLDPRT (1.4 MB) (SW2020)
Thank you again Sylk, you have been a precious help to me you have a crazy level
I plugged the 2 sides with a circular extrusion (not fused)
Now I am in accordance with the customer's request to have a half egg conforming to its flat shape but deformed on a round of 100 mm diameter I'm now going to do the convex part, the bump to make a hollow egg
Then I try on my CAM software
I saw your 3D egg, the skin fits well
Can I use your 2 cinematic video to explain to the client the flat correspondence and make an advertising video on youtube
Hello @criss It is I who should thank you; It's thanks to your question that I was able to think about a method, and find this solution
Do you have a particular reason not to merge them? Oh yes, to convert the surface object into a density body you have to use the " Thicken " surface function, with a tiny thickness. Then you can merge the " caps ". However, as I recommended above, it is better to:
In other words, you make a rod that you align on the center of the roller, like an axis, and you fuse it.
Indeed, with a few adjustments to the settings to change the albedo of the base skin appearance, it's pretty convincing.
I have nothing against the use of videos, on the other hand if it's to make an ad/demo it's better that I make one again with the right egg size, so that the proportions match, because for my experiments I had sketched an egg with a snatch and used an arbitrary size (smaller than yours). I was scheduled to redo the play to share it, so it's not a problem.
Small bonus question: when I made the half egg as an attachment I used the Insert an image in the sketch function. When I do this in a row when I zoom in the 3D is no longer in the middle of the screen at all and knows quite annoying, did I do something incorrect or is it a bug of sw 2020
Sorry, I don't quite understand your question. If you have the opportunity to illustrate it, it will help us understand.
Otherwise, if I may say so, I notice a defect in the tracing on your egg, which is not made to make the final result happy, especially for the unmolding, or even more basically for the creation of the mold:
Just for machining, these defects at first glance insignificant make it go from the easy&cheapy category to the hard& expensive category. And of course, these shapes hinder the proper demoulding.
The on the screenshot below the 3D object egg instead of being in the middle of the screen with a zoom size enlarges and well it is very small and remote and I think the sketch image knows that produces this bug
Move your image to the middle of your original axis and it will no longer be offset. Or you break the link with the image and you re-constrain your sketch so that it is centered on your origin and no more problems. Edit: or last solution move a body and you re-constrain it on the origin
When opening your egg, all the sketches are under constraint (in blue), which is very risky, a bad handling and presto, everything goes to lollipop. Re-constrain all this, permanently delete your sketch image if useless and possibly if necessary you change your origin point for your half egg. In a sketch, the essential thing is not to leave anything in blue. (under duress)
help to me you have a crazy level
