Curves

I intersected two spheres

and I wanted to delete the face in the created circle. But it is not possible to delete the face. When I select, so it is whole sphere face selected. Why?

If your circle is well drawn on the sphere
with what have drawn this circle ?

Select the Sphere, select the circle: right click / Intersection Selected
Now you can select inside the circle and erase what you want

PS You can post the SKP file (save as V6) in the forum
Upload attachment
it's better than an image!

I did the circle with sphere, the little one. I saw a video tutorial but am confused. She speaks very fast and the demonstration is short.

Thx for the V6

Seems you have successed to kill the intersection's faces

Again when you speak about a video give the adress of the link

For draw on curvated surface there is a cool plug Tools on surface by Fredo 6

So with it you can draw a circle directly on a sphere

Your spheres are groups. When you do any intersection, the intersection lines are always created in the context you are in. In your model, they are outside of the groups therefore they do not interact with their geometry. This means that if you want to get the edges to separate the surfaces (so that you can delete them and make holes), you will need to edit the group, select its geometry and do the intersection that way (with the model).

Alternatively, you can explode the big sphere, select its surface and one or more of the smaller sphere group and intersect only selected.

Yet one thing I am interested how to make the sphere looking more smooth, more rounded. I have some tools like BZ toolbar or blend but this one does not seem to do the job. I can add more details with sandbox but this will not make it look like real sphere.

No me. I have done some action with LSS tools. As I remember that was Follow edges... There was not this kind of sphere in original modul. The original sphere was from 3D Warehouse: Geodesic sphere 02.

I tried to destroy the faces again, but did not succeed to get same result as before. The sphere looked more bizarre on previous try. The image from now:

You can see the 3D join component was the ovalish 3D object and face was a triangle just by purple dot.

You can draw your own sphere with the Follow me tool
from diffrent behaviour
here one
incease your number of segments / circle or arc circle following that you want
maybe max is 100

Click the circle call the Followme tool then click the surface

This is my result

Try with this one
Don't hesitate to make some try, Arc surface perpendicular, no perpendicular, rotate it, surface out the circle etc...
It's a funny world!

Very nice sphere. How to complete? I never succeed to close it with Follow me. I remember there was some truck in tutorial, but that one never worked for me.

Edit:
Now I succeed to close it. But if I would have bigger object, how to follow whole the path? I know there is some trick like double click or triple click.

When I will add a texture to the sphere, how can I resize size of the texture. I know how to do it with one face, but with more faces, it looks like imposible.

There is a hole in top and a stair. I had these problems. When I wanted to draw a circle inside circle:

I could not find the center point
I had to start upward so when I wanted to move it back, I could not to find centerpoint again
I had problem to draw the circle on different axis even that I hold arrow right or left.

FOr find the center of an arc circle or a circle use this plug by Chris Fullmer
Just 2 segments following are sufficient

Else you can just draw a line on the top, a mine on the bottom (so diameter)
then draw a line from middle of the 2 diameters)

rumcajs

Well, nice plug-ins you recommend to me. Nice tricks. I have seen one more plugin in the video here:
http://forums.sketchucation.com/viewtopic.php?t=18963
he bended a "pipe". Do you know what plugin it is? It also looks very cool.

pilou

Yes It's Fredo Scale by Fredo 6

For the diameter without plug you can also made this
Menu WIndows / Model Info and put the maximum precision (number of decimal)

When you draw your line after the first click look inside the little box screen right bottom
When the length is maximum it's your diameter

I something did wrong because around the sphere of mine, there is a circle in the middle. I wanted to delete the circle but the circle is exploded. I think I could just to rotate the sphere in good position (circle to be horizontal)... select, and then I found that ... oh no there are also other edges selected not only the circle... So is there a way how to select the whole cicle? I use selection tools but did not find a way. And the second problem, is that if I delete the circle, so it deletes some surface under it. Probably I had made some mistake when creating the sphere.

Group (or make component) for geometry you've finished to separate it and protect it from damage by your next actions. Back up work. Save an extra file now and then.

These are just funny tries no need for components here or backing up. But in the future work sure. Bending the tubes is very funny

rumcajs

Do you know how to bend her hand with fredo scale tools
so it would looked naturally bended?

pilou

Super cool never thought to bend a 2D image with the Fredo Scale!
