An idea occurred to have a script to apply bumps to a surface.
The surface could be a plane, or a torus, or an elliptical torus, or a sphere, etc.
A sphere or ellipsoid would be created, intersecting the surface, or solid, to become the bump.
Multiple trims could be done, Merge of connecting edges, if any, and then a blend of the two edges done.

It seems that a script is not necessary.

Select the surface.

Select a point on the surface and create a sphere there. (Or other 3d shape, such as an ellipsoid.)

Move the sphere up or down on the surface, maintaining an overlap. Nudge would work here.
(It would be nice to have a Nudge with a slider. (?))
(The surface normal of the surface (of say a solid) are likely outward.)

Select the sphere, and select the surface.
Do a Fillet, with an appropriate radius, not too big.
The bottom % of the sphere is automatically deleted.
It would be nice to have a slider on the fillet. (?)
Join.

For an ellipsoid protruding from both sides, both ends are filleted.

A Blend could have a different profile than the arc of a fillet.

How about grafting the Blend command into the work flow of the Fillet command?

Hi Brian,

re:
> How about grafting the Blend command into the work flow of the Fillet command?

It is like that already, inside the Fillet command you can set the option for Shape: G1 Blend / G2 Blend / G3 Blend to have it make blend surfaces instead of circular arc cross-section surfaces.

Hi Michael,

Thank you, good to learn more about MoI's abilities.

- Brian

I see that for a sphere intersecting a plane, they can be filleted from the "top", or the "bottom" depending on which side of the sphere is picked.

Blendcap can also be used to make bumps.
Rough outline, limited testing:
Select closed curve on (flat?) surface, DelCorners or fillet corners.
The closed curve could be from polygon, voronoi, freeform curve, circle, ellipse, etc.
Extrude curve.
Delete curve,
Select edge of extrusion, Merge edges.
Blend edge, and adjust position, with respect to original surface.
Select the Blend surface and original surface, and Fillet with desired Fillet parameters and method.

have you a little image of the process or result ?

Hi Pilou,

I'll get some png's made.

- Brian

Hi Ben your creative approach is apreciated - would be great so see some images as Pilou asked for !

Safari hat has memories of grandfathers beekeeping hat, over which was a veil net. (It should have used an "ellipsoid" rather than a sphere.)

Two are fillet voronoi's, on which new Batch Fillet was applied to round corners, before surface ellipse. One of which utilized Blend Cap, giving slightly "wrinkled" surface.

One is skinny ellipsoid.

Still learning how to use imgbox site...There seem to be multiple permutations.
Only one of the above 3 links need be used. There are arrow keys for the other images...

I've been making an enclosure for Prusa 3+ filament printer, for printing higher temp filaments like Nylon, ASA, and Polycarbonate.
It is cubical, and uses 2020 aluminum extrusions, 6mm polycarbonate sheets, ventilation with activated carbon for the noxious fumes, etc.

<< Still learning how to use imgbox site...
Nothing more easy and speedy! And you will obtain a data base images very organized! :)
(just choice very descriptive names! )
and you can put little animations as GIF is permitted!
You can share your gallery! https://imgbox.com/g/bf5JrSWQD0
Click on the first image of your gallery then the arrow (up right page) until the last one if necessary!

For put an image on this forum use these 2 balises!


Here some tips! (made of course with imgbox! :)
It's free ...i have many Gigas on it!
At the end it's very more easy to click on image for have it's address!

Start


First Image(s) and coice of the nature of Gallery Target Gallery (don't use the Do not create a Gallery except for a speedy not important one)


Name and choose your image wanted on your computer


Again if you want another image(s)


You can take this code for only one image but more easy to display an image and Right Click on it for have the direct address link!


You can see all your Galleries in a glance! (i have for the moment 576 ones :)


Your gallery before i add this 7 th image! ;)


Have fun!
For any Gif animation...here the new BatchEditCircles by Michael Gibson;)

Thank you Pilou,
Very useful information!

- Brian

Maybe you miss this one for crossing post! :)

Another trick as there is not an easy list of your galleries (when you have many much like me) you can make this little tip
Upload tempo image in adding in a name gallery list!
Call this gallery see if wanted is inside
then erase the tempo image! ;)
It's that i made for the little image above
I had moi1, moi2...moi9 galleries but of course don't remember where was inside the moi9 ! :)
So...and you must click on it for be sure because thumbnails are like a close up in this particular case!
